Specific Inhibitors of Puromycin-Sensitive Aminopeptidase with a 3-(Halogenated Phenyl)-2,4(1H,3H)-quinazolinedione Skeleton
摘要:
Specific puromycin-sensitive aminopeptidase (PSA) inhibitors with a 3-(halogenated phenyl)-2,4(1H,3H)-quinazolinedione skeleton were prepared and their structure-activity relationships were investigated. The nature (F, Cl or Br), number and position(s) of the halogen atom(s) introduced into the 3-phenyl group were concluded to be critical determinants of the inhibitory activity.
6-trisubstituted phenyl)uracil derivatives has been synthesised and assayed for insecticidal/acaricidalactivity. The assay indicated certain requirements for optimal insecticidalactivity, which can be summarised as follows: (a) the substituents on the phenyl ring should possess hydrophobicity and electron-withdrawing properties, and the sum of their volumes determines the level of activity; (b) the substituent

presence of variously functionalized substituents on the nitrogen atom, including sterically demanding ones and reactive halogens. No erosion of the enantiopurity was observed in the case of optically active isocyanates. One of the substrates prepared has been employed in Charette's type chemoselective addition of a Grignardreagent to access an alpha-chloroketone.

日期:——
A derivative of (+)-(E)-4-phenylbut-3-ene-2-ol is shown by X-ray crystallography to be of (R) configuration, confirming the assumption in the literature that the absoluteconfiguration of (+)-(E)-4-phenylbut-3-ene-2-ol is (R).
