(4-Oxo-2-thioxothiazolidin-3-yl)acetic acids as potent and selective aldose reductase inhibitors

(4-Oxo-2-thioxothiazolidin-3-yl)acetic acids exhibit a wide range of pharmacological activities. Among them, the only derivative used in clinical practice is the aldose reductase inhibitor epalrestat. Structurally related compounds, [(5Z)-(5-arylalkylidene-4-oxo-2-thioxo-1,3-thiazolidin-3-yl)]acetic acid derivatives were prepared previously as potential antifungal agents. This study was aimed at the determination of aldose reductase inhibitory action of the compounds in comparison with epalrestat and evaluation of structure-activity relationships (SAR). The aldose reductase (ALR2) enzyme was isolated from the rat eye lenses, while aldehyde reductase (ALR1) was obtained from the kidneys. The compounds studied were found to be potent inhibitors of ALR2 with submicromolar IC50 values. (Z)-2-(5-(1-(5-butylpyrazin-2-yl)ethylidene)-4-oxo-2-thioxothiazolidin-3-yl)acetic acid (3) was identified as the most efficacious inhibitor (over five times more potent than epalrestat) with mixed-type inhibition. All the compounds also exhibited low antiproliferative (cytotoxic) activity to the HepG2 cell line. Molecular docking simulations of 3 into the binding site of the aldose reductase enzyme identified His110, Trp111, Tyr48, and Leu300 as the crucial interaction counterparts responsible for the high-affinity binding. The selectivity factor for 3 in relation to the structurally related ALR1 was comparable to that for epalrestat. SAR conclusions suggest possible modifications to improve further inhibition efficacy, selectivity, and biological availability in the group of rhodanine carboxylic acids.

Linear and nonlinear optical properties of new azo aminosalicylic acid derivatives

4-(3-Allyl-4-oxo-2-thioxo-thiazolidin-5-ylazo) salicylic acid (4-ATS) and 5-(3-allyl-4-oxo-2-thioxo-thiazolidin-5ylazo) salicylic acid (5-ATS) were synthesized and characterized by different spectroscopic techniques. The XRD patterns of 4-ATS and 5-ATS in powder form were recorded and found to be polycrystalline with monoclinic crystal system. Thin films of 4-ATS and 5-ATS were successfully prepared by thermal evaporation technique onto optical flat quartz substrates. Linear and nonlinear optical properties of 4-ATS and 5-ATS were investigated by spectrophotometric measurements. The spectral distribution of refractive index of 5-ATS thin films showed normal dispersion in the non-absorbing region of spectra, while 4-ATS showed nonlinear response. The optical energy gap and the electronic transition type for 4-ATS and 5-ATS were calculated. The electronic absorption and emission spectra were recorded for pristine and UV-irradiated 4-ATS and 5-ATS thin films. The absorption coefficient spectra for 4-ATS and 5-ATS were found to decrease with increasing UV exposure time, while the intensity of emission spectra for both of the derivatives were enhanced with increasing UV exposure time. Recovery in dark reversed the effect of UV-radiation.

Structural design, synthesis and pharmacological evaluation of thiazoles against Trypanosoma cruzi

Chagas disease is one of the most significant health problems in the American continent. benznidazole (BDZ) and nifurtimox (NFX) are the only drugs approved for treatment and exhibit strong side effects and ineffectiveness in the chronic stage, besides different susceptibility among T. cruzi DTUs (Discrete Typing Units). Therefore, new drugs to treat this disease are necessary. Thiazole compounds have been described as potent trypanocidal agents. Here we report the structural planning, synthesis and anti-T cruzi evaluation of a new series of 1,3-thiazoles (7-28), which were designed by placing this heterocycle instead of thiazolidin-4-one ring. The synthesis was conducted in an ultrasonic bath with 2-propanol as solvent at room temperature. By varying substituents attached to the phenyl and thiazole rings, substituents were observed to retain, enhance or greatly increase their anti-T. cruzi activity. In some cases, methyl at position 5 of the thiazole (compounds 9, 12 and 23) increased trypanocidal property. The exchange of phenyl for pyridinyl heterocycle resulted in increased activity, giving rise to the most potent compound against the trypomasigote form (14, IC50trypo = 0.37 mu M). Importantly, these new thiazoles were toxic for trypomastigotes without affecting macrophages and cardiomyoblast viability. The compounds were also evaluated against cruzain, and five of the most active compounds against trypomastigotes (7, 9, 12, 16 and 23) inhibited more than 70% of enzymatic activity at 10 mu M, among which compound 7 had an IC50 in the submicromolar range, suggesting a possible mechanism of action. In addition, examination of T. cruzi cell death showed that compound 14 induces apoptosis. We also examined the activity against intracellular parasites, revealing that compound 14 inhibited T cruzi infection with potency similar to benznidazole. The antiparasitic effect of 14 and benznidazole in combination was also investigated against trypomastigotes and revealed that they have synergistic effects, showing a promising profile for drug combination. Finally, in mice acutely-infected with T cruzi, 14 treatment significanty reduced the blood parasitaemia and had a protective effect on mortality. In conclusion, we report the identification of compounds (7), (12), (15), (23) and (26) with similar trypanocidal activity of benznidazole; compounds (9) and (21) as trypanocidal agents equipotent with BDZ, and compound 14 with potency 28 times better than the reference drug without affecting macrophages and cardiomyoblast viability. Mechanistically, the compounds inhibit cruzain, and 14 induces T. cruzi cell death by an apoptotic process, being considered a good starting point for the development of new anti-Chagas drug candidates.

Synthesis of Diflunisal Thiazolidinones as Anticancer Agents

A series of diflunisal 4-thiazolidinones were synthesized. Some selected compounds were determined at one dose towards the full panel of 60 human cancer cell lines by National Cancer Institute. 2′,4′-Difluoro-4-hydroxy-N-[4-oxo-2-(thiophen-2-yl)-1,3-thiazolidin-3-yl]biphenyl-3-carboxamide (4a) demonstrated the most marked effect on K-562 cancer cell line with 58.59 % growth inhibition at 10 mu M. Compound 4a was evaluated in vitro using the MTT colorimetric method against human leukemia cell line K-562 and mouse embryonic fibroblasts cell line NIH-3T3 at different doses for cell viability and growth inhibition. Compound 4a exhibited anticancer activity with IC50 value of 5.2 mu M against K-562 cells and did not display cytotoxicity towards NIH-3T3 cells compared with diflunisal. In addition, this compound could be an interesting prototype as an antiproliferative agent.

Synthesis, Biological Evaluation and Molecular Docking Studies of Novel Coumarinylthiazolyl Iminothiazolidinone Hybrids as Potent Urease Inhibitors

The present paper is designed to explore the potential of an important class of heterocycles coumarinylthiazolyl iminothiazolidinone to inhibit jack bean urease. The final products 6a-j were prepared by condensation of substituted aldehydes with intermediate 5 in sodium methoxide/methanol mixture. The synthesized compounds were characterized by their FTIR, H-1, C-13 NMR and mass spectral data. The synthesized coumarinylthiazolyl iminothiazolidinone hybrids 6 a-j were evaluated for their potential to inhibit urease activity. All the synthesized derivatives showed remarkable inhibitory activity with IC50 ranging 8 to 34 nM, while IC50 of standard thiourea is 18.5 nM. The compound 5-(2,4-Dichlorobenzylidene)-2-(4-(2-oxo-2H-chromen-3-yl)thiazol-2-yl imino) thiazolidin-4-one 6 h bearing 2,4-di-chloro substituted phenyl ring exhibited excellent activity with IC50 value 8 nM. In silico molecular docking studies was performed against urease enzyme PDBID 4H9 M and predicted possible binding modes in catalytic site for these active compounds. The thiazole nitrogen in compound 6 h formed a strong hydrogen bonding interaction with side chain Gln635 having distance 2.01 angstrom and rest part of this inhibitor is present close to Val640. The most potent derivative 6 h have highest binding affinity with binding energy -6.178 kcal/mol. It is concluded based upon our results that 6 a and 6 h are most promising compounds from this series and provide a basis for rationale design of most potent urease inhibitors.
