GSK3β/p38α mitogen-activated proteinkinaseinhibitors and identified N-(4-(4-(4-fluorophenyl)-2-methyl-1H-imidazol-5-yl)pyridin-2-yl)cyclopropanecarboxamide (1) as a potent dual inhibitor of both target kinases. In this study, we aimed to design selective GSK3β inhibitors based on our pyridinylimidazole scaffold. Our efforts resulted in several novel and potent GSK3β inhibitors with IC50 values in the
the structural and magnetic investigation, electronic spectroscopy was used to investigate the spin-state transition. An initial attempt to utilize the bifunctional coordination ability of the ω-(1H-tetrazol-1-yl) carboxylicacids for preparation of mixed-metallic 3d–4f coordinationpolymers resulted in a novel one-dimensional gadolinium-oxo chain system with the ω-(1H-tetrazol-1-yl) carboxylic acid

A new and efficient total synthesis has been developed to obtain plagiochin G (22), a macrocyclic bisbibenzyl, and four derivatives. The key 16-membered ringcontainingbiphenyl ether and biaryl units was closed via an intramolecular SNAr reaction. All synthesized macrocyclic bisbibenzyls inhibited Epstein–Barr virus early antigen (EBV-EA) activation induced by the tumor promoter 12-O-tetradecanoylphorbol-13-acetate
已开发出一种新的有效的全合成方法以获得斜角烷基素G(22),大环双联苄基和四种衍生物。含有联苯醚和联芳基单元的关键的16元环是通过分子内的S N Ar反应封闭的。所有合成的大环双联二苄基均抑制了Raji细胞中肿瘤启动子12 - O-十四烷酰phorbol -13-乙酸盐(TPA)诱导的爱泼斯坦-巴尔病毒早期抗原(EBV-EA)活化,因此是潜在的癌症化学预防剂。
Synthesis of tetrazole analogues of phosphonohydroxamic acids: An attempt to improve the inhibitory activity against the DXR
lipophilic inhibitors of the DXR, the second enzyme of the MEP pathway for the biosynthesis of isoprene units in most bacteria, by replacing the phosphonate group of fosmidomycin derivatives by a tetrazoyl moiety capable of multiple hydrogen bonding. The N- and C-substituted tetrazole analogues of phosphonohydroxamate inhibitors were synthesized and tested on the DXR of Escherichia coli. This work
