  Exploring the isoform selectivity of TGX-221 related pyrido[1,2-a]pyrimidinone-based Class IA PI 3-kinase inhibitors: Synthesis, biological evaluation and molecular modelling

  摘要：

  A novel series of TGX-221 analogues was prepared and tested for their potency against the p110 alpha, p110 beta, and p110 delta isoforms of the PI3K enzyme, and in two cellular assays. The biological results were interpreted in terms of a p110 beta comparative model, in order to account for their selectivity towards this isoform. A CH2NH type linker is proposed to allow binding into the specificity pocket proposed to accommodate the high p110 beta-selectivity of TGX-221, although there was limited steric tolerance for substituents on the pendant ring with the 2-position most favourable for substitution.
