Methyl-triflate-mediated dearylmethylation of N-(arylmethyl)carboxamides via the retro-Mannich reaction induced by electrophilic dearomatization/rearomatization in an aqueous medium at room temperature
Serine/threonine protein kinases Aurora A, B, and C play essential roles in cell mitosis and cytokinesis, and a number of Aurora kinase inhibitors have been evaluated in the clinic. Herein we report the synthesis and their antiproliferation of 3,5-disubstituted-2-aminopyrazines as kinases inhibitors. Amongst, 4-((3-amino-6- (3,5-dimethylisoxazol-4-yl)pyrazin-2-yl)oxy)-N-(3-chlorophenyl) benzamide (12Aj)
The present invention relates to new compounds having modulatory (inhibitory and stimulatory) activity on serine peptidases and proteases in general and dipeptidyl peptidase IV, prolyl oligopeptidase (PO), dipeptidyl peptidase II (DPP II), fibroblast activation protein &agr; (FAP&agr;), lysosomal Pro—X carboxypeptidase and elastase in particular. These new compounds can be used for the treatment of a variety of disease states in which these peptidases are involved.

Using 3‐(4‐cyano phenoxy)‐6‐methyl‐4‐(3‐trifluoromethylphenyl) pyridazine (compound A) as a leading compound, a total of 24 novel 3‐(substituted phenoxy)‐6‐methyl‐4‐(3‐trifluoromethylphenyl) pyridazine derivatives containing two electron‐withdrawing groups on the benzene ring (acylamine and oxime ether) were synthesized. Their herbicidal, insecticidal activities were bioassayed, and the herbicidal
使用3-(4-氰基苯氧基)-6-甲基-4-(3-三氟甲基苯基)哒嗪(化合物A)作为主要化合物,总共有24种新颖的3-(取代苯氧基)-6-甲基-4-(合成了在苯环上含有两个吸电子基团的3-三氟甲基苯基)哒嗪衍生物(酰胺和肟醚)。对它们的除草,杀虫活性进行了生物测定,化合物CD-2在300 g / ha下对甘蓝型油菜的除草活性为97.6%,在此浓度下优于商品除草剂双氟苯尼草,并且与前者的活性相当。化合物甲。化合物CD-4,CD-5,CJ-3和CJ-5表现出出色的杀灭蚜虫Kaltenbach的杀虫活性(> 95%)。结果表明,肟醚取代基比酰基胺具有更好的漂白和除草活性。对位取代的漂白和除草活性优于间位取代。肟醚哒嗪衍生物苯环上的对位似乎是影响其除草活性的关键活性部位之一。
