The present study describes a novel series of ATP-competitive PKC inhibitors based on the 2,6-naphthyridine template. Example compounds potently inhibit the novel Protein Kinase C (PKC) isotypes δ, ε, η, θ (in particular PKCε/η, and display a 10–100-fold selectivity over the classical PKC isotypes. The prototype compound 11 was found to inhibit PKCθ-dependent pathways in vitro and in vivo. In vitro
本研究描述了基于2,6-萘啶模板的一系列新的ATP竞争性PKC抑制剂。示例化合物有效抑制新型蛋白激酶C(PKC)同种型δ,ε,η,θ(尤其是PKCε/η),并且相对于经典PKC同种型具有10-100倍的选择性,原型化合物11具有抑制作用。体外和体内PKCθ依赖性途径,在体外,α-CD3/ a-CD28诱导的淋巴细胞增殖可在10%大鼠全血中被有效阻滞;在小鼠中,有11种剂量依赖性抑制金黄色葡萄球菌肠毒素B触发的IL口服给药后-2血清水平。
