AbstractThe mass spectral fragmentations of some 2,3‐diaryl‐1,3‐thiazolidin‐4‐ones were established by comparing spectra and by using exact mass measurements. The major fragment ions were identified and their relative importances related to substituent effects and bond strengths. Good correlations were observed between the relative abundances of some of the breakdown products and the Hammett σ constants of substituents in the aromatic rings.
Visible-light-driven photocatalytic activity of ZnO/g-C3N4 heterojunction for the green synthesis of biologically interest small molecules of thiazolidinones
properties including high surface area, high loading, extraordinary electronic properties, and easy separation for increases photocatalytic performance has remained a challenge in photocatalytic applications. Herein, an environmentally benign approach was developed to fabricate graphiticcarbonnitride (g-C3N4) decorated with nanorods zinc oxide (ZnO). The photocatalytic activity of ZnO decorated on the

tubulin-targeting anticancer agents. In the current study, a novel series of thiazolidin-4-one-based derivatives (7a–q) was designed by merging the pharmacophoric features of some COXs inhibitors and tubulin polymerization inhibitors. Compounds 7a–q were synthesized and evaluated for their cytotoxicactivity against MCF7, HT29, and A2780 cancer cell lines (IC50 = 0.02–17.02 μM). The cytotoxicity of 7a–q was also
