K-252c是蛋白激酶C(PKC)和蛋白激酶A(PKA)的抑制剂,具有细胞渗透性、可逆性和ATP竞争性,IC50值分别为2.45 μM和25.7 μM。K-252c可抑制β内酰胺酶(β-lactamase)、苹果酸脱氢酶和糜蛋白酶,IC50值分别为8、8和10 μM[1]。
蛋白激酶可通过化学添加磷酸基团修饰其它蛋白质(磷酸化)。磷酸化可通过改变酶活性、细胞定位或与细胞内其它蛋白的相互作用导致靶蛋白(底物)功能的改变。PKA及PKC是AGC激酶家族的重要成员。
在PC12h细胞中,K-252a可以阻断神经生长因子(NGF)诱导的突起生长和蛋白磷酸化的改变[2]。
在严重联合免疫缺陷(SCID)小鼠-人皮肤银屑病模型中,使用 K-252c治疗2周后,病情得到显著改善[3]。
