Aim: A novel series of 2-arylimino-5-arylidenethiazolidin-4-ones 12a-n were synthesized and all the target compounds were fully characterized by IR, 1H NMR, 13C NMR, mass spectroscopy and elemental analysis. Materials & methods: All the target compounds were evaluated for their COX inhibition by enzyme immunoassay kit and in vivo anti-inflammatory activity. Results: Tested compounds were found more potent inhibitors of COX-2 (IC50 = 0.54-3.14 M) than COX-1 (IC50 = 4.97-11.52 M). The ulcerogenic liability of compounds 12(d, e, f, h, k, m) was performed and showed gastric safety more than or comparable to celecoxib. Conclusion: In addition, docking study of the most potent and selective compound 12h into COX-2 active site revealed that this target compound assumed interactions and binding pattern similar to that of as a cocrystallized ligand bromocelecoxib (S-58).

A new series of benzimidazole bearing pyridine derivatives were synthesized by condensation of 1,2-phenylenediamine with 2-oxo-1,2-dihydro-pyridine-3-carboxylic acid derivative 2 in phosphoric acid to give 3-(1Hbenzo[ d]imidazol-2-yl)-pyridin-2(1H)-one derivative 3. Compound 3 on further reaction with a mixture of phosphorus oxychloride and phosphorus pentachloride gave 2-(2-chloro-) pyridin-3-yl)-1H-benzo[d] imidazole derivative 4. Moreover, 4 were reacted with different amines to give 3-(1H-benzo[d]imidazol-2-yl)-N-(substituted) pyridin-2-amine derivatives 5a-c. Meanwhile, N-(N-(substituted) sulfamoyl) pyridin-3-yl)-1H-benzo[d]imidazole-1-carboxamide derivatives 7a,b were synthesized by reaction of 5c with chlorosulfonyl isocyanate to give 2-(pyridin-3-yl)-1H-benzo [d]imidazole-1-carbonyl) sulfamoyl chloride derivative followed by reaction of the latter with different amines. On the other hand, upon treatment compound 4 with hydrazine hydrate gave the hydrazide derivative 8. The reaction of compound 8 with different alkyl/arylisothiocyanates gave the corresponding thiosemicarbazide derivatives 9a-d, while their cyclo condensation reaction with ethyl chloro acetate gave the corresponding thiazolidin-4-one derivatives 10a-c. Moreover, condensation of 10a,c with aromatic aldehydes afforded the corresponding 5-arylidine-thiazolidin-4-one derivatives 11a,b. Cytotoxic evaluation of some of the newly synthesized compounds against human breast carcinoma cell line MCF-7 revealed that, these compounds showed promising activity compared with Doxorubicin as positive control.

New Advances in Chemical Research, May 2021. Electric Literature of 7025-19-6, Chemical engineers ensure the efficiency and safety of chemical processes, adapt the chemical make-up of products to meet environmental or economic needs, and apply new technologies to improve existing processes. In a document type is Article, and a compound is mentioned, 7025-19-6, 3-(4-Oxo-2-thioxothiazolidin-3-yl)propanoic acid, introducing its new discovery.

In this study, a series of benzimidazole-rhodanine conjugates were designed, synthesized and investigated for their topoisomerase II (Topo II) inhibitory and cytotoxic activities. The results from Topo II-mediated pBR322 DNA relaxation and cleavage assays showed that the synthesized compounds might act as Topo II catalytic inhibitors. Certain compounds displayed potent Topo II inhibition at 10 muM. The cytotoxic activities of these compounds against HeLa, A549, Raji, PC-3, MDA-MB-201, and HL-60 cancer cell lines were evaluated. The results indicated that these compounds exhibited strong antiproliferative activity. A good relationship was observed between the Topo II inhibitory potency and the cytotoxicity of these compounds. The structure-activity relationship revealed that the electronic effects, the phenyl group, and the rhodanine moiety were particularly important for the Topo II inhibitory potency and cytotoxicity.
