Photochemical synthesis of benzoxazolo[3,2-b]isoquinolin-11-one and isoquinolino[3,2-b][1,3]benzoxazin-11-one under basic conditions
摘要:
Irradiation of N-phenyl substituted isoquinolines in acetonitrile containing 1 M NaOH in a multilamp reactor (MLR) furnished benzoxazolo[3,2-b]isoquinolin-11-ones. In contrast, irradiation of the N-benzyl substituted isoquinoline derivative under the same conditions afforded the hydrolysed N-benzylbenzamide derivative. The isoquinolinobenzoxazine was obtained by irradiating the N-benzyl substituted isoquinoline derivative at higher basic conditions. The required isoquinolines were synthesized under solvent-free, solid supported microwave conditions. (c) 2005 Elsevier Ltd. 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
