Based on our prior work, we reported the design, synthesis, and biological evaluation of fifty-two new triazolothiadiazine-based analogues of CA-4 and their preliminary structure-activity relationship. Among synthesized compounds, Iab was found to be the most potent derivative possessing IC50 values ranging from single-to double-digit nanomolar in vitro, and also exhibited excellent selectivity over the normal human embryonic kidney HEK-293 cells (IC50 > 100 μM). Further mechanistic studies revealed that Iab significantly blocked tubulin polymerization and disrupted the intracellular microtubule network of A549 cells. Moreover, Iab induced G2/M cell cycle arrest by regulation of p-cdc2 and cyclin B1 expressions, and caused cell apoptosis through up-regulating cleaved PARP and cleaved caspase-3 expressions, and down-regulating of Bcl-2. Importantly, in vivo, Iab effectively suppressed tumor growth of A549 lung cancers in a xenograft mouse model without obvious signs of toxicity, confirming its potential as a promising candidate for cancer treatment.

(Chemical Equation Presented) A fast, efficient synthesis of 5-substituted-1,3,4-thiadiazole-2-thiols was successfully developed, assessed using green chemistry matrices, and compounds were screened for their in vitro nitrification inhibitory activity. The greener method was superior with higher energy efficiency, E(nvironmental) factor, atom economy, atom efficiency, carbon efficiency, and reaction mass efficiency.

A series of substituted 3,6-diphenyl-7H-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazines were prepared and analyzed as inhibitors of phosphodiesterase 4 (PDE4). Synthesis, structure-activity relationships, and the selectivity of a highly potent analogue against related phosphodiesterase isoforms are presented.
