One-pot synthesis of 4-thiazolidinone derivatives catalyzed by zinc acetate-schiff base complex immobilized on mesoporous molecular sieve MCM-41

A new simple and efficient one-pot synthesis of thiazolidinone derivatives via aldehydes, amines and mercaptoacetic acid in the presence of Zn(OAc)2-Schiff base complex immobilized on MCM-41 is described. A variety of aldehydes and amines were engaged in the study and afforded respective thiazolidinones in high yield (up to 98%). Moreover, consistent activity of recovered catalyst was found to be almost same up to five cycles in 80% yield.

Synthesis and identification of quinoline derivatives as topoisomerase I inhibitors with potent antipsoriasis activity in an animal model

Psoriasis is a chronic inflammatory and immune-mediated skin disease. Although certain agents have shown clinical success in treating psoriasis, development of safe and effective strategies for the treatment of this condition remains important. Research suggests that DNA topoisomerase I (Topo I)inhibitors may have potent psoriasis-ameliorating effects. Here, 25 quinoline derivatives were synthesized and identified as Topo I inhibitors. These compounds inhibited the 12?O?tetradecanoylphorbol-13-acetate-induced mouse ear inflammation. The most potent analogs, 5i and 5l, suppressed the expression of inflammatory cytokines in lipopolysaccharide-stimulated HaCaT cells. Additionally, the lead compounds significantly improved imiquimod-induced psoriasis-like inflammation in mice. Moreover, the expression levels of cytokines and inflammatory mediators, such as interleukin (IL)-17A, IL-22, IL-23, nuclear factor-kappaB subunit p65, tumor necrosis factor-alpha, and interferon-gamma, were dramatically inhibited in the dorsal skin of 5i- and 5l-treated mice. These findings indicate that the inhibition of Topo I activity may potentially be an effective strategy for psoriasis treatment.

Theoretical study of the structural features and antioxidant potential of 4-thiazolidinones

4-Thiazolidinone compounds have been reported to display good antioxidant activity. In the present work, the five-membered ring has been studied extensively at the DFT-B3LYP/6-311(++)G(d,p) level of theory. The geometrical features of the ring have been explored in the gas and solvent phase. Various molecular descriptor characteristics of the antioxidant compound have been calculated and compared with the reference antioxidant, trolox. Three probable antioxidant mechanisms, hydrogen atom transfer (HAT), single electron transfer (SET), and sequential proton loss electron transfer (SPLET), have been explored, both in the gas and solvent phase. It has been found that the ring exerts its antioxidant activity predominantly following the HAT pathway, both in the gas and solvent phase. In order to determine the feasibility of the overall redox reaction, the standard redox potentials have been calculated for the ring and free radicals. Furthermore, the effect of substitution on the antioxidant parameters of the ring has been explored. Results indicate that substitution at the C2 position is advantageous over that at C5 in improving such parameters. Along with this, the effect of substitution at the C2 position on the proton affinity of the C5 position has also been investigated in detail.

Microwave-assisted synthesis, characterization and antimicrobial potencies of n-substituted iminothiazodin-4-one derivatives

The biggest and most multifaceted class of organic compounds includes heterocyclic compounds. Currently, several heterocyclic compounds are iden-tified, and persistently gratefulness to tremendous synthetic work and synthetic usefulness, the number is increasing exponentially. In most fields of science, including medicinal, pharmaceutical, and agro-chemistry, heterocyclic compounds have a function, and biochemistry is also another area. In this research article, the green approach is administered for achieving the nitrogen, oxygen and sulphur centered five-membered heterocyclic derivatives. By taking the whole thing in to account of hetero-chemistry, the moderately effective analog for gram-positive and gram-negative bacterial strains was shown for the five-membered heterocyclic compound series of N-substituted iminothiazodine-4-one and N-(benzylideneamino)thiazol-4(5H). Throughout the synthesized series of the compound 6c revealed very much active potent against the gram-negative Escherichia coli bacterial strain and the compound 6b point out moderately active against the gram-positive Bacillus subtilis bacteria strains in accordance with the standard drug. The 5a and 6a compounds showed very strong activity against the fungal strain of Candida albicans and 6b as well as 6c were more active and highly potent than the standard drugs against Aspergillus niger species. In the view of this research drive states that all the synthesized compounds might be used for the development for further heterocyclic entities.
