An expedient synthesis of new 2-(furoxan-3-yl)thiazolidin-4-one derivatives

A series of new biologically interesting furoxan-3-thiazolidinones have been synthesized via onepot three-component reaction of furoxan aldehydes, anilines and mercaptoacetic acid. The multicomponent reaction involves condensation of furoxan aldehyde with aniline to give imine; the formed imine undergoes nucleophilic addition with mercaptoacetic acid, followed by cyclisation with loss of H2O to obtain the desired products. All the synthesized compounds were well characterized using spectral techniques and confirmed by an X-ray crystal structure for one compound.

Leucettamine B analogs and their carborane derivative as potential anti-cancer agents: Design, synthesis, and biological evaluation

Leucettamine B is a natural product found in marine sponge Leucetta microraphis. Several of analogs of its family, such as aplysinopsine and clathridine, are medicinally active molecules which have applications in many pharmaceuticals and healthcare products; however, thus far, leucettamine B has not been studied. In this report, we describe the synthesis of a new class of analogs of leucettamine B obtained by Knoevenagel condensation using a microwave reactor. The 25 newly synthesized compounds were tested against MDA-MB-468, SW480, and Mahlavu cell lines for anticancer activity. Among them, the carborane-based compound (Z)-5-(benzo[d] [1,3] dioxol-5-ylmethylene)-3-(1-closo-carboranyl)-2-thioxo -thiazolidin-4-one (49) and (Z)-5-(benzo[d][1,3]dioxo1-5-ylmethylene) 3 (2 (pyrrolidin-1-yl)ethyl)-2-thioxothiazolidin-4-one (31) derivatives were found to have the most potential for use against tumor cells. The carborane derivative 49 had the lowest IC50 value against the SW480 cell line (4.7 mu M) and the Mahlavu (6.6 mu M) cell line. Furthermore, compound 31 also had a low IC50, value against SW480 (7.5 mu M). Our research shows that leucettamine B analogs might have potential for use in cancer chemotherapy.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 627-93-0 help many people in the next few years. Quality Control of Dimethyl adipate.

NOVEL 4-OX0-[1, 3-THIAZOLIDINE-3-YL] BENZAMIDE AND ITS DERIVATIVES AS POTENT ANTIPROTOZOAL FERREDOXIN MARKER INTERACTION WITH LIGANDS: DISCOVERY OF NEW DRUG

In this paper, we synthesized the compound N-[2-(4-methoxyphenyl)-4-oxo-1,3-thiazolidin-3-yl]pyridine-4- carboximide(IV) were synthesized. . The chosen ligands have conformational stability and structural diversity in relation to the bound ligands of the N-[2-(4-methoxyphenyl)-4-oxo-1,3-thiazolidin-3-yl]pyridine-4-carboximide (IV) crystal structure. The ligand structures used in docking were obtained from Pubchem compound database. Ligands were identified as per the pharmacokinetic parameter and solubility. The active site i.e. ferredoxin enzyme in the protein interacts with ligands of the substrate and gives rise to the catalytic activity to test ligands that helps in determining the binding pattern of the ligands to the active site of ferredoxin enzyme. The pharmacological study was undertaken to evaluate the effects of substituents on the antiprotozoal activity. The synthesized compounds exhibited better antiprotozoal activity towards Paramecium caudatum, Vorticella campanula, it can be inferred that as the OCH3, SH, NH group substitution on the ring causes an increase in the intensity of the activity against Paramecium caudatum, Vorticella campanula , Opalina ranarum and have potent antiprotozoal activity.

Evaluation of 4-thiazolidinone derivatives as potential reverse transcriptase inhibitors against HIV-1 drug resistant strains

Rapid emergence of drug resistance is crucial in management of HIV infection limiting implementation of efficacious drugs in the ART regimen. Designing new molecules against HIV drug resistant strains is utmost essential. Based on the anti-HIV-1 activity, we selected four 4-thiazolidinone derivatives (S009-1908, S009-1909, S009-1911, S009-1912) and studied their interaction with reverse transcriptase (RT) from a panel of 10 clinical isolates (8 nevirapine resistant and two susceptible) using in silico methods, and inhibition pattern using in vitro cell based assays. On the basis of binding affinity observed in in silico analysis, 2-(2-chloro-6-nitrophenyl)-3-(4, 6-dimethylpyridin-2-yl) thiazolidin-4-one (S009-1912) was identified as the lead molecule followed by S009-1908, S009-1909 and S009-1911. The in vitro activity against the same panel was assessed using TZM-bl assay (IC50: 0.4-11.44 mu g/ml, TI: 4-126) and subsequently in PBMC assay against a nevirapine resistant clinical isolate (IC50: 0.8-6.65 mu g/ml, TI: 8.31-11.43) and standard strain from NIH ARRRP (IC50: 0.95-3.6 mu g/ml, TI: 9-26). The study shows analogue with pyrimidin-2-yl amino substitution at N-3 position of thiazolidin-4-one ring (S009-1908, S009-1909, S009-1911) exhibited enhanced activity as compared to pyridin-2-yl substituted derivatives (S009-1912), suggesting the use 4-thiazolidinones for developing potent inhibitors against HIV-1 drug resistant strains.

Thiazolidine Derivatives Attenuate Carrageenan-Induced Inflammatory Pain in Mice

Background: Peripheral inflammation leads to the development of persistent thermal hyperalgesia and mechanical allodynia associated with increased expression of interleukin-1 beta (IL-1 beta) in the spinal cord. The aim of the present study was to investigate the effects of thiazolidine derivatives, 1b ([2-(2-hydroxyphenyl)-1,3-thiazolidin-4-yl](morpholin-4-yl) methanone) and 1d (2-hydroxy-4-{[2-(2-hydroxyphenyl)-1,3-thiazolidine-4-carbonyl] amino}benzoic acid), on thermal hyperalgesia, mechanical allodynia and on IL-1 beta expression during carrageenan-induced inflammation in the spinal cord in mice. Inflammatory pain was induced by injecting 1% carrageenan into the right hind paw of the mice. Methods: The animals were administered thiazolidine derivatives, 1b and 1d (1 mg/kg, 3 mg/kg, or 10 mg/kg), intraperitoneally 30 minutes before carrageenan administration. The animals’ behavior was evaluated by measuring thermal hyperalgesia, mechanical allodynia, and motor coordination. The IL-1 beta expression was measured by enzyme-linked immunosorbent assay. Acute and sub-acute toxicity studies were conducted to evaluate the toxicity profile of compounds. Results: Treatment with the thiazolidine derivative, 1b and 1d, attenuated carrageenan-induced thermal hyperalgesia and mechanical allodynia at doses of 1 mg/kg, 3 mg/kg, and 10 mg/kg. No motor coordination deficits were observed in animals. The compounds also reduced IL-1 beta expression in the spinal cord of mice. Acute and sub-acute toxicity studies revealed that both compounds were safe. Conclusion: The compounds exhibit promising activity against inflammatory pain due to their ability to produce anti-hyperalgesic and anti-allodynic effects and to inhibit IL-1 beta expression in the spinal cord.

Thiazole-Bearing 4-Thiazolidinones as New Anticonvulsant Agents

Here, we describe the synthesis and anticonvulsant activity of thiazole-bearing hybrids based on 2-imino-4-thiazolidinone and 2,4-dioxothiazolidine-5-carboxylic acid cores. The structure of target compounds was based on the following: (i) A combination of two thiazole cores; (ii) similarity to ralitolin’s structure; (iii) the compliance with structural requirements for the new anticonvulsants. Target compounds were synthesized via known approaches based on Knoenavegel reaction, alkylation reaction, and one-pot three-component reaction. Anticonvulsant properties of compounds were evaluated in two different models-pentylenetetrazole-induced seizures and maximal electroshock seizure tests. Among the tested compounds 5Z-(3-nitrobenzylidene)-2-(thiazol-2-ylimino)-thiazolidin-4-one Ib, 2-[2,4-dioxo-5-(thiazol-2- ylcarbamoylmethyl)-thiazolidin-3-yl]-N-(2-trifluoromethylphenyl)acetamide IId and (2,4-dioxo-5- (thiazol-2-ylcarbamoylmethylene)-thiazolidin-3-yl)acetic acid ethyl ester IIj showed excellent anticonvulsant activity in both models. The directions of compounds modification based on SAR aspects were discussed. The results of the study provide a basis for further study of the anticonvulsant properties of selected thiazole-thiazolidinones.

Crystal structures of two (Z)-2-(4-oxo-1,3-thiazolidin-2-ylidene) acetamides

The crystal structures of two (oxothiazolidin-2-ylidene) acetamides, namely (Z)-2-[2-(morpholin-4-yl)-2-oxoethylidene] thiazolidin-4-one, C9H12N2O3S, (I), and (Z)-N-(4-methoxyphenyl)-2-(4-oxothiazolidin-2-ylidene) acetamide, C12H12N2O3S, (II), are described and compared with a related structure. The Z conformation was observed for both the compounds. In (I), the morpholin-4-yl ring has a chair conformation and its mean plane is inclined to the thiazolidine ring mean plane by 37.12 (12)degrees. In (II), the benzene ring is inclined to the mean plane of the thiazolidine ring by 20.34 (14) degrees. In the crystal of (I), molecules are linked by N-H center dot center dot center dot O hydrogen bonds, forming C(6) chains along the b-axis direction. The edge-to-edge arrangement of the molecules results in short C-H center dot center dot center dot O and C-H center dot center dot center dot S interactions, which consolidate the chain into a ribbon-like structure. In the crystal of (II), two N-H center dot center dot center dot O hydrogen bonds result in the formation of C(8) chains along the b-axis direction and C(6) chains along the c-axis direction. The combination of these interactions leads to the formation of layers parallel to the bc plane, enclosing R-4(4) (28) rings involving four molecules.
