Herbicidal activity of 2-substituted 1,3,4-(2H)-isoquinolinetriones
摘要:
A series of 2-substituted 1,3,4-isoquinolinetriones (B) 1-15, precursors of the phthalamic acids and of the 1,3-dihydro-1-hydroxy-3-oxo-1-isobenzofurancarboxamides (F), possessing root antigravitropic activities, were prepared and evaluated for herbicidal activity on weeds and crops. Among the compounds examined, several derivatives were very active against weeds, in many cases more active than the commercially available herbicides used as the reference standards. Phytotoxicities on crops, selectivity and persistence of herbicidal effect were observed. (C) 1999 Elsevier Science S.A. All rights reserved.
Specific inhibitor of puromycin-sensitive aminopeptidase with a homophthalimide skeleton: identification of the target molecule and a structure–activity relationship study
,3-dione (2: PIQ-22) was found to be a potent and specific inhibitor of puromycin-sensitive aminopeptidase (PSA). Lineweaver-Burk plot analysis showed that PSA is inhibited by PIQ-22 in a non-competitive manner. Structure -activity relationship studies indicated that tautomerism of the imidobenzoylketone group in the cyclicimide moiety of the PIQ-22 skeleton is important for the inhibitory activity
Thalidomide shows moderate inhibitory activity toward neuronal nitric oxide synthase (nNOS) and inducible NOS (iNOS), but not toward endothelial NOS (eNOS). Structural development studies of thalidomide yielded novel phenylhomophthalimide-type NOS inhibitors with enhanced activity and different subtype selectivity. (C) 2004 Elsevier Ltd.
