identified as potent inhibitors of 5-lipoxygenase in vitro exhibiting IC50's of less than 1 microM. An investigation of structure-activity relationships showed that the most potent inhibitors of this series are the 5-phenyl derivatives. The corresponding thiazolidin-4-one analogues were found to be relatively inactive. The 4-hydroxythiazoles were active inhibitors against 5-lipoxygenase in both intact rat

The MEK1 kinase plays a critical role in key cellular processes, and as such, its dysfunction is strongly linked to several human diseases, particularly cancer. MEK1 has consequently received considerable attention as a drug target, and a significant number of small-molecule inhibitors of this kinase have been reported. The majority of these inhibitors target an allosteric pocket proximal to the ATP
(GABA) receptor antagonists (e.g., fipronil), new GABAergic 5,5-disubstituted 4,5-dihydropyrazolo[1,5-a]quinazolines were designed via a scaffold-hopping strategy and synthesized with a facile method. Among the 50 target compounds obtained, compounds 5a, 5b, 7a, and 7g showed excellent insecticidal activities against a susceptible strain of Plutella xylostella (LC50 values ranging from 1.03 to 1.44 μg/mL)

its amphiphilic derivatives markedly activate the enzyme. To date, all porphyrins studied are naturally occurring compounds or their derivatives, possessing substituents at β‐positions. Such porphyrins are of limited abundance and their derivatives or analogues are difficult to synthesize, while synthetic meso‐substituted porphyrins are easy to prepare. Thus, we have decided to study their effect on
