GZD824 是一种口服生物可利用的 Bcr-Abl 抑制剂，适用于 Bcr-Abl(WT, IC50: 0.34 nM) 和 Bcr-Abl(T315I, IC50: 0.68 nM)。

GZD824 is a novel orally bioavailable inhibitor against a broad spectrum of Bcr-Abl mutants including T315I. GZD824 tightly bound to Bcr-Abl(WT) and Bcr-Abl(T315I) with K(d) values of 0.32 and 0.71 nM, respectively, and strongly inhibited the kinase functions with nanomolar IC(50) values. GZD824 potently suppressed proliferation of Bcr-Abl-positive K562 and Ku812 human CML cells with IC(50) values of 0.2 and 0.13 nM, respectively. GZD824 also displayed good oral bioavailability (48.7%), a reasonable half-life (10.6 h), and promising in vivo antitumor efficacy. It induced tumor regression in mouse xenograft tumor models driven by Bcr-Abl(WT) or the mutants and significantly improved the survival of mice bearing an allograft leukemia model with Ba/F3 cells harboring Bcr-Abl(T315I). GZD824 represents a promising lead candidate for development of Bcr-Abl inhibitors to overcome acquired imatinib resistance.
