CNX-500 是一种由与生物素化学连接的共价 Btk 抑制剂 (CC-292) 组成的探针。CNX-500 保留了对 Btk 的抑制活性 (IC50 为 0.5 nM) 以及与 Btk 形成共价键的能力。CNX-500 对激酶表皮生长因子受体和上游 Src 家族激酶 (包括 Syk 和 Lyn) 的抑制作用较低。
CNX-500 is a probe consisting of a covalent Btk inhibitor (CC-292) chemically linked to biotin. CNX-500 retains inhibitory activity against Btk (IC50 of 0.5 nM) and the ability to form a covalent bond with Btk. CNX-500 has low inhibitory effects on kinase epidermal growth factor receptor, and upstream Src-family kinases including Syk and Lyn[1].
