Two classes of piperazinone-containing thieno[3,2-d]pyrimidines were designed and synthesized as new PI3Kδ inhibitors in this study. Detailed SAR study with respect to the piperazinone substituents at the 6-position of thieno[3,2-d]pyrimidine core demonstrated that piperazinone-containing thieno[3,2-d]pyrimidines would be more potent and selective for PI3Kδ than their piperazine counterparts, which
在本研究中,设计并合成了两类含哌嗪酮的噻吩并[3,2- d ]嘧啶类化合物作为新的PI3Kδ抑制剂。关于噻吩并[3,2- d ]嘧啶核6-位哌嗪酮取代基的详细SAR研究表明,含哌嗪酮的噻吩并[3,2- d ]嘧啶比哌嗪对PI3Kδ更有效且更具选择性对应物,从而导致发现了几种有效的PI3Kδ抑制剂,与艾德拉利西比相比,它们对一组非霍奇金淋巴瘤(NHL)细胞系具有相当或更好的抗增殖活性。我们的研究将促进基于含哌嗪酮的噻吩并[3,2- d ]嘧啶骨架的新型PI3Kδ抑制剂的开发。

A class of substituted or 6,7-ring fused [1, 2, 3]triazolo[1,5-&agr;]-pyrimidine derivatives, possessing an optionally substituted cycloalkyl, phenyl or heteroaryl substituent at the 3-position and an amino moiety at the 5-position, are selective ligands for GABA
A
receptors, in particular having high affinity for the &agr;2 and/or ◯subunit thereof, and are accordingly of benefit in the treatment and/or prevention of disorders of the central nervous system, including anxiety and convulsions.
Guided by structure-based design, we synthesized two novel series of potent inhibitors of BACE1 and generated extensive SAR around both the prime and non-prime side binding pockets. The key feature of both series is a cyclic amine motif specifically crafted to achieve interactions with both the flap and with the S2' pocket.
