Photocaging of a tight-binding bisubstrateinhibitor of cAMP-dependent proteinkinase (PKA) with a nitrodibenzofuran-based group fully abolished its inhibitory potency. The affinity difference between the photocaged and the active inhibitor was over 5 orders of magnitude. The photocaged inhibitor disrupted the PKA holoenzyme in cell lysates upon photolysis under a 398 nm LED.

A series of 4‐(piperazin‐1‐yl)‐7H‐pyrrolo[2,3‐d]pyrimidine derivatives was synthesized and evaluated as Akt inhibitors by optimization of a weak screening lead (1). Typically, compounds 5q and 5t significantly improved the Akt1 inhibitory potency with IC50 values of 18.0 and 21.3 nM, respectively, with desirable antiproliferative effect against the celllines LNCaP and PC‐3. The inhibitors 5q and 5t
Design, Synthesis and Biological Evaluation of Histone Deacetylase Inhibitors Based on Pyrrolo[2,3‐<i>d</i>]pyrimidine and Pyrrolo[2,3‐<i>b</i>]pyridine Scaffolds
We designed and synthesized a series of HDACinhibitorsbased on pyrrolo[2,3-d]pyrimidine and pyrrolo[2,3-b]pyridine scaffolds. Compound B3 (in grey) exhibits potentinhibitory activity against HDACs 1, 2, 3, 6, and 8. It shows potent antiproliferative effects against three tumour cell lines, with two- to sixfold improvement over SAHA. This series provides valuable lead compounds for the future treatment
我们设计并合成了一系列基于吡咯并[2,3- d ]嘧啶和吡咯并[2,3- b ]吡啶支架的HDAC抑制剂。化合物B3(灰色)对 HDAC 1、2、3、6 和 8 表现出有效的抑制活性。它对三种肿瘤细胞系表现出有效的抗增殖作用,比 SAHA 提高两到六倍。该系列为未来血液恶性肿瘤的治疗提供了有价值的先导化合物。
