AB  - bstract: Concomitant use of two or more drugs in therapy is becoming a more frequent phenomenon and clinically relevant drug–drug interactions at the level of binding to human serum albumin (HSA) are more often. The influence of fluoroquinolones–sparfloxacin, levofloxacin, and ciprofloxacin, on the interaction between tigecycline and HSA, was investigated in vitro by means of fluorescence and absorption spectroscopy. The results of UV–Vis and fluorescence spectroscopy showed that the fluorescence quenching of HSA was a result of the formation of new complexes through a static quenching process. The binding constants (Ka) and the number of binding sites (n) of all systems were calculated. The presence of sparfloxacin and ciprofloxacin increases and that of levofloxacin slightly decreases the binding constant of the HSA–tigecycline system. Competitive binding studies in the presence of site-specific markers showed that tigecycline was not significantly displaced by ibuprofen, but warfarin showed a significant displacement of tigecycline. These results suggest that the competitive binding of tigecycline and warfarin to HSA exists. The results confirm that the binding site of tigecycline is mainly located in Sudlow’s site I (subdomain IIA) of HSA. Graphic abstract: [Figure not available: see fulltext.

AB  - Hesperidin is the flavonoid heteroside most found in citrus species, such
as grapefruit, lemon and orange. It is applied in the treatment of numerous
cardiovascular diseases, with many products containing hesperidin in
combination with other flavonoid heterosides or vitamin C. The aim of this
study was to develop and validate a simple, rapid and sensitive and lowcost
method for determination of hesperidin in tablets and orange juices.
The developed spectrophotometric method is based on the formation of
the Zn(II)-hesperidin complex in 70 v/v% methanol at pH 3.12, with max of
absorption at λmax= 283 nm. The method of variation of equimolar solutions
confirmed the stoichiometry of the complex as hesperidin: zinc= 2:1.
The stability constant of the complex was obtained by the Bjerrum method
and it is logβ2 = 17.01 at pH 3.12. Linearity range for the developed method
was defined as 0.61-7.32 μg/mL, (confirmed by coefficient of determination,
r2 = 0.9882), while limits of detection and quantification were calculated
as LOD = 0.15 μg/mL and LOQ = 0.45 μg/mL. Fairly high precision of the
method is indicated by low values of CV, varying in the range 0.26-1.23%.
The proposed method fulfills all aimed requirements, and it was successfully
applied for determination of hesperidin in tablets with recovery value 92.2
% and commercially available orange juices.

AB  - ABSTRACT  Aggregation of the cationic surfactant cetyltrimethylammonium bromide 
(CTAB) in water (W) and acetonitrile-water (ACN-W) mixtures of different 
composition (10-20% (v/v) of ACN) was studied through fluorescence 
measurements. The CTAB critical micellar concentration (CMC) and the 
micelle aggregation number (Nagg) were determined at T = 22.0 °C. It was 
found that for increasing volume ratios of ACN to W, the CMC value attains 
a minimum (1.22 mM) at 15% (v/v) ACN while Nagg is continuously 
decreasing as ACN content in the ACN-W mixture increases. The effect of 
this dipolar aprotic solvent on the CTAB micelle formation can be interpreted 
in terms of its considerably hydrogen bonding ability and influence on balk phase properties (solvophobic effect).

AB  - Flavonoids are a group of polyphenolic compounds widely present in the herbal world
representing an important part of human diet. Quercetin, which is a flavanol, makes 70% of total daily
intake of flavonoids. Because of the characteristic chemical structure, quercetin has the ability of
complexing metals and antioxidative ability.
Using equimolar solution variation method it was determined that quercetin makes a complex
with zinc(II)-ion in acidic environment (pH 5.25), in stoichiometric relation quercetin:zinc(II)-ion =
2:1, with absorption maximum on λmax=363 nm. The ability of quercetin to make complex
compounds with zinc(II)-ion was used to develop simple, precise and accurate assay to determine the
content of quercetin in various samples of heterogeneous composition.
The proposed indirect spectrophotometric method can selectively determine quercetin in
concentrations ranging from 0.1 to 6.0 mg/L. LOD and LOQ were derived from the calibration curve
and estimated as 0.03 mg/L and 0.1 mg/L respectively. Developed method is reproductive and
accurate, as indicated by high value of correlation coefficient R=0.99996 and low value of
SD=0.00122. Method was successfully used to determine quercetin content in dietary supplement
tablets. Dietary supplements, proscribed for therapeutic and/or profilactic pruposes, usualy content
quercetin combined with other flavonoids and ascorbic acid. Therefore, it was necessary to test the
selectivity of proposed method.
The reliability of the method was checked out by newly developed RP-HPLC/UV method for
capsules with direct determination of quercetin after separation. The good agreement between the two
methods indicates the applicability of the proposed spectrophotometric method for quercetin
determination in dietary supplement tablets with high reproducibility, and enables direct and simple
determination without its prior extraction from samples.
In addition, the antioxidative ability of quecetin and zinc(II)-quercetin complex was
determined using oxidation-reduction standardized methods DPPH and FRAP. The same samples
were tested for antimicrobial activity against seven laboratory control strains of bacteria and one
yeast. As a result of those tests, there are no obstacles to combine quercetin and zinc in the same
formulation.

methods indicates the applicability of the proposed spectrophotometric method for quercetin
determination in dietary supplement tablets with high reproducibility, and enables direct and simple
determination without its prior extraction from samples.
In addition, the antioxidative ability of quecetin and zinc(II)-quercetin complex was
determined using oxidation-reduction standardized methods DPPH and FRAP. The same samples
were tested for antimicrobial activity against seven laboratory control strains of bacteria and one
yeast. As a result of those tests, there are no obstacles to combine quercetin and zinc in the same
formulation.",

AB  - We propose a sensitive and selective spectrofluorimetric method for the determination of flavonoids as expressed in 'quercetin equivalent' in apple juices. The method is based on the strong emission of the aluminium(III)-quercetin complex at 480 nm with excitation at 420 nm, and it is successfully applied for the determination of flavonoids in commercial apple juices and compared with results obtained in reference spectrophotometric determination. The flavonoid content in commercial apple juices was found to range from 5.53 to 15.55 mg/l quercetin equivalent. The very good agreement between the two methods indicates the suitability of the proposed spectrofluorimetric method for the precise and accurate determination of flavonoids. In addition, the total polyphenol content was determined spectrophotometrically using the Folin-Ciocalteu (FC) method and the antioxidative activity of the tested juices was tested in a DPPH assay and these values were correlated with each other. The obtained profiles of compounds with antioxidative ability lead us to conclude that fruit juice labels based only on fruit % might sometimes misinform consumers.

AB  - A series of 23 novel anthraquinone-chalcone hybrids containing amide function was synthesized and structurally characterized. Sixteen compounds exerted strong cytotoxic activities against K562, Jurkat and HL-60 leukemia cell lines and significantly lower cytotoxic effects against normal MRC-5 cells, indicating very high selectivity in their anticancer action. The compounds 6g, 6u and 6v activate apoptosis in K562 cells through the extrinsic and intrinsic apoptotic pathway. The compound 6e triggered apoptosis in K562 cells only through the extrinsic apoptotic pathway. Treatment of K562 cells with each of these four compounds caused decrease in the expression levels of MMP2, MMP9, and VEGF, suggesting their anti-invasive, antimetastatic and antiangiogenic properties. The compounds 6g and 6v downregulated expression levels of miR-155 in K562 cells, while compounds 6e and 6u upregulated miR-155 levels in treated cells, in comparison with control cells. The structurebased 3-D QSAR models for 6f, 6e, 6i and 61 describe pro-apoptotic activity against caspase-3.

AB  - The co-administration of several drugs in multidrug therapy may alter the binding of each drug to human serum albumin (HSA) and, thus, their pharmacology effect. Therefore, in this study, the interaction mechanism between HSA and two fluoroquinolones (FQs), sparfloxacin (SPF) and levofloxacin (LVF), was investigated using fluorescence and absorption methods in the absence and presence of the competing drugtigecycline (TGC). The UV-Vis and fluorescence spectroscopy results showed that the fluorescence quenching of HSA was a result of the formation of the HSA-SPF and HSA-LVF complexes. The fluorescence quenching of HSA-TGC revealed that tigecycline can regulate the binding sites, binding mode and binding affinity of fl uoroquinolones. The binding constants (KA) and binding sites (n) of the interaction systems were calculated. The results confirmed that the KA values of the HSA-FQ system decreased in the presence of TGC, indicating that TGC can affect the binding ability of FQ for HSA. This interaction may increase the free plasma concentration of unbound FQ and enhance their pharmacology effect.
AB  - Istovremena primena nekoliko lekova, u multilek terapiji, može izmeniti njihovo vezivanje za humani serumski albumin (HSA) i njihov farmakološki efekat. Zbog toga, u ovom radu je proučavan mehanizam interakcije između HSA i dva fluorohinolona (FQs): sparfloksacina (SPF) i levofloksacina (LVF) fluorescentnim i apsorpcionim metodama u odsustvu i prisustvu konkurentskog leka - tigeciklina (TGC). Rezultati UV-Vis i fluorescentne spektroskopije su pokazali da je gašenje fluorescencije u HSA rezultat formiranja HSA-SPF i HSA-LVF kompleksa. Gašenje fluoroscencije u HSA-TGC je pokazalo da tigeciklin može regulisati mesta vezivanja, način vezivanja i afinitet vezivanja fluorohinolona. Konstante vezivanja (KA) i broj vezujućih mesta (n) za interakcije u sistemu su izračunate. Rezultati su potvrdili da su vrednosti KA u HSA-FQ sistemu, smanjene u prisustvu TGC, a to ukazuje da TGC može da utiče na sposobnost vezivanja FQ za HSA. Ova interakcija može povećati slobodnu koncentraciju u plazmi nevezanog FQ i poboljšati njegov farmakološki efekat.

AB  - The plasma protein binding (PPB) data of twelve antipsychotics (aripiprazole, clozapine, olanzapine, quetiapine, risperidone, sertindole, ziprasidone, chlorpromazine, flupentixol, fluphenazine, haloperidol, zuclopenthixol) were estimated using computed molecular descriptors, which included the electronic descriptor - polar surface area (PSA), the constitutional parameter - molecular weight (Mw), the geometric descriptor - volume value (Vol), the lipophilicity descriptor (logP) and aqueous solubility data (logS), and the acidity descriptor (pK(a)). The relationships between computed molecular properties of the selected antipsychotics and their PPB data were investigated by simple linear regression analysis. Low correlations were obtained between the PPB data of the antipsychotics and PSA, Mw, Vol, pKa, logS (R  lt  0.30) values, while relatively higher correlations (0.35 lt R-2 lt 0.70) were obtained for the majority of logP values. Multiple linear regression (MLR) analysis was applied to access reliable correlations of the PPB data of the antipsychotics and the computed molecular descriptors. Relationships with acceptable probability values (P lt 0.05) were established for five lipophilicity descriptors (logP values) with application of the acidity descriptor (pKa) as independent variables: AlogP (R-2=0.705), XlogP3 (R-2=0.679), ClogP (R-2=0.590), XlogP2 (R-2=0.567), as well as for the experimental lipophilicity parameter, logPexp (R-2=0.635). The best correlations obtained in MLR using AlogP and pKa as independent variables were checked using three additional antipsychotics: loxapine, sulpiride and amisulpride, with the PPB values of 97%, "less than" 40% and 17%, respectively. Their predicted PPB values were relatively close to the literature data. The proposed technique confirmed that lipophilicity, together with acidity significantly influences the PPB of antipsychotics. The described procedure can be regarded as an additional in vitro approach to the modeling of the investigated group of drugs.

The proposed spectrophotometric method is based on the formation of the Zn2+-rutin complex in methanol 70% (v/v) at pH 8.52, and detection at lambda(max)= 410 nm. The concentration range over which the response was linear was 0.3-12.2 mu g ml(-1). The limit of detection (LOD) and the limit of quantification (LOQ) were 0.21 mu g ml(-1) and 0.63 mu g ml(-1), respectively. The proposed method was successfully applied to the determination of rutin in herbal dietary supplements. The reliability of the method was checked by comparison with results obtained by the established RP-HPLC/UV method. The proposed method fulfills all aimed requirements.

AB  - A simple, accurate and precise method based on the fluorescence properties of the aluminum(III)-quercetin complex, for the determination of quercetin, has been developed and validated. The complex has strong emission at pH 3.30, lambda(em) = 480 nm, with lambda(ex) = 420 nm. The linearity range of quercetin determination was 1.5-60.5 ng ml(-1) with LOD 0.09 ng ml(-1) and LOQ 0.27 ng ml(-1). Recovery values in the range of 99.9-100.2% indicate a good accuracy of the method. The established method was applied for the determination of quercetin in capsules, with a recovery value of 98.3%, standard deviation of 0.22% and coefficient of variation of 0.09%. The reliability of the method was checked by the newly developed RP-HPLC/UV method for capsules with the direct determination of quercetin after separation. The good agreement between the two methods indicates the applicability of the proposed spectrofluorimetric method for quercetin determination in pharmaceutical dosage forms, with high reproducibility, and enables the direct and simple determination without its prior extraction from samples. The proposed spectrofluorimetric method has much better sensitivity and LOD and LOQ values that are about 1000 times lower than data reported in the literature.

AB  - The speciation of Cu2+, Ni2+ and Zn2+ ions in the presence of the fluoroquinolones (FQs) moxifloxacin, ofloxacin, levofloxacin and ciprofloxacin, in human blood plasma was studied under physiological conditions by computer simulation. The speciation was calculated using an updated model of human blood plasma including over 6,000 species with the aid of the program Hyss2009. The identity and stability of metal-FQ complexes were determined by potentiometric (310 K, 0.15 mol/L NaCl), spectrophotometric, spectrofluorimetric, ESI-MS and H-1-NMR measurements. In the case of Cu2+ ion the concentration of main low molecular weight (LMW) plasma complex (Cu(Cis) His) is very slightly influenced by all examined FQs. FQs show much higher influence on main plasma Ni2+ and Zn2+ complexes: (Ni(His)(2) and Zn(Cys) Cit, respectively. Levofloxacin exhibits the highest influence on the fraction of the main nickel complex, Ni(His)(2), even at a concentration level of 3 x 10(-5) mol/L. The same effect is seen on the main zinc complex, Zn(Cys) Cit. Calculated plasma mobilizing indexes indicate that ciprofloxacin possesses the highest mobilizing power from plasma proteins, toward copper ion, while levofloxacin is the most influential on nickel and zinc ions. The results obtained indicate that the drugs studied are safe in relation to mobilization of essential metal ions under physiological conditions. The observed effects were explained in terms of competitive equilibrium reactions between the FQs and the main LMW complexes of the metal ions.

AB  - In the present work, the rapid RP-HPLC method with UV (DAD) detection for simultaneous quantification of bioflavonoids: quercetin, apigenin, catechin, epicatechin, kaempferol, and luteolin in Brassica oleracea species samples (cauliflower, broccoli, and Brussels sprouts) was developed with the aid of LC-Simulator (ACD LabsA (R) suite) software. A series of extracts obtained with different extraction method were evaluated for antioxidant activity. The optimal conditions for separation and quantification were established after nine scouting runs entered to LC-Simulator software. The optimized separation was achieved on Hypersil GOLD aQ column with isocratic elution and mobile phase composition A:2 % acetic acid in water and B:acetonitrile in 91:9 (v/v %) ratio. The R (s) values were in the range from 2.6 to 8.00, indicating good selectivity of the method. The obtained results generally show good agreement with published data. Low detection limits (0.02-0.055 mu g/mL) were obtained with acceptable recoveries (90-109 %). Total time of analysis was less than 11 min; therefore, the proposed method represents significant improvement over existing methods. Extracts from Brassica vegetables, obtained using different extraction procedures, were studied for their radical scavenging effects. Scavenging of DPPH showed different kinetics at the beginning of the assay period and after 15 min from the initialization of reaction. Different kinetics suggested the presence of polymerized and/or less active antioxidants with different scavenging mechanisms for particular polyphenolic compounds.

AB  - In this review, Raman spectroscopy is described as a new and potentially powerful diagnostic tool in comparison to routine biochemical tests. Advanced instrumentation and new Raman spectroscopy techniques enable rapid and simultaneous identification and/or determination of several biochemical parameters, such as glucose, acetone, creatinine, urea, lipid profile, uric acid, total protein, etc., with a very low limit of detection. Raman spectroscopy could also be applied in molecule and cell characterization, as well as diagnostics of atherosclerosis in its early stage. Raman spectroscopy is nondestructive and could be applied to all kinds of samples, which simplifies the diagnostics of numerous diseases and pathologic states. Special attention is paid to literature data illustrating the application of Raman spectroscopy for transdermal glucose monitoring and cancer diagnostics.

AB  - The spectrofluorometric method based on fluorescence ability of aluminium - hesperidin complex for the determination of hesperidin in orange juice is proposed. The linearity range of hesperidin in methanolicaqueous solution was 0.08 - 18.0 μg/mL with LOD and LOQ values as 0.023 μg/mL and 0.070 μg/mL, respectively, and recovery values in the range 97.8 - 99.7 %. Method was simplified by omitting any of surphactant agents usually applied in similar procedures, and successfully applied for the determination of hesperidin in orange juices commercially available on the Serbian market.

Utvrđena je oblast linearnosti za određivanje hesperidina u metanolno-vodenim rastvora od 0.08 do 18.0 μg/mL, pri čemu je LOD= 0.023 μg/mL i LOQ= 0.070 μg/mL, a recovery vrednost 97.8 - 99.7 %. Metoda je pojednostavljena izostavljanjem često korišćenih površinski aktivnih materija koje se koriste u sličnim procedurama i uspešno je primenjena za određivanje sadržaja hesperidina u sokovima od pomorandže prisutnim na tržištu Srbije.",

AB  - A fluorometric method, based on the fluorescence properties of the aluminium(III)-hesperidin complex, for the determination of hesperidin in human plasma and pharmaceutical forms has been developed and validated. The complex shows a strong emission in the presence of the surfactant betain sulphonate SB 12 at 476 nm with excitation at 390 nm. The linearity range for pharmaceutical forms of hesperidin was 0.06-24.4 μg mL-1 with a limit of detection, LOD, of 0.016 μg mL-1 and a limit of quantification, LOQ, of 0.049 μg mL-1. Recovery values in the range 99.3-99.7 % indicate good accuracy of the method. A linear dependence of the intensity of fluorescence of the complex on the concentration of hesperidin in plasma was obtained in concentration range from 0.1-12.2 μg mL-1. The LOD was 0.032 μg mL-1 while LOQ was 0.096 μg mL-1. Recovery values were in the range 98.4-99.8 %. The reliability of the method was checked by an LC-MS/MS method for plasma samples and an HPLC/UV method for tablets with direct determination of hesperidin after separation. Linearity range in determination of hesperidin in pharmaceutical forms was obtained in the range from 0.05 to 10.00 μg mL-1. The LOD was 0.01 μg mL-1 and the LOQ was 0.03 μg mL-1. The linearity range for the determination of hesperidin in plasma was 0.02-10.00 μg mL-1 with an LOD 0.005 μg mL-1 and an LOQ of 0.015 μg mL-1. The good agreement between the two methods indicates the usability of the proposed fluorometric method for the simple, precise and accurate determination of hesperidin in clinical and quality control laboratories.

AB  - Twenty five 4-aminomethylidene derivatives obtained from 3-phenyl-2-pyrazolin-5-one and 1,3-diphenyl-2-pyrazolin-5-one were synthesized and tested for their antiproliferative activity against human breast cancer MDA-MB-361 and MDA-MB-453 cell lines. The compounds derived from 1,3-diphenyl-2-pyrazolin-5-one exhibited the most remarkable activity in the treatment of both cell lines. In vitro antiproliferative activities were accompanied by an important apoptotic fraction of both cell lines; also, compounds inhibited key endothelial cell functions implicated in invasion and angiogenesis. QSAR methods were performed in order to analyze the influence of structural features of the compounds investigated on the antiproliferative potential on MDA-MB-361 and MDA-MB-453 cancer cells. One-parameter heuristic analysis was performed and different whole molecule and fragmental descriptors were considered for rationalization of mechanism of interaction of these compounds with active place of hypothetical target included in tumorigenesis.
