Dasatinib (GMP)

Dasatinib (BMS-354825) (GMP) is a GMP-grade Dasatinib (HY-10181). GMP-grade small molecules can be used as adjuvant agents in cell therapy. Dasatinib (BMS-354825) is an orally active, ATP-competitive, dual Src/Bcr-Abl inhibitor with potent antitumor activity. The K_i values ​​for Src and Bcr-Abl are 16 pM and 30 pM, respectively. Dasatinib inhibits Bcr-Abl and Src with IC₅₀ values ​​of less than 1.0 nM and 0.5 nM, respectively. Dasatinib also induces apoptosis and autophagy^[1]. In Vitro:Dasatinib demonstrates significant activity against Bcr-Abl, Src, Lck, Yes, c-Kit, PDGFRβ, p38, Her1, Her2, FGFR-1, and MEK with IC₅₀s of <1.0, 0.50, 0.40, 0.50, 5.0, 28, 100, 180, 720, 880, and 1700 nM, respectively^[1].
Dasatinib shows antiproliferative activities aversus K562 chronic myelogenous leukemia (CML), PC3 human prostate tumor, MDA-MB-231 human breast tumor, and WiDr human colon tumor cell lines with IC₅₀s of <1.0 nM, 9.4 nM, 12 nM, and 52 nM, respectively^[1]. In Vivo:Dasatinib (5 mg/kg and 50 mg/kg, qd×10d, 5 on-2 off) possesses potent antitumor activity and a high safety margin in a K562 xenograft model of chronic myelogenous leukemia (CML), demonstrating complete tumor regressions and low toxicity at multiple dose levels^[1].
Dasatinib (10 mg/kg) has a pharmacokinetic profile appropriate for continued advancement into in vivo efficacy studies. Dasatinib (10 mg/kg) demonstrates favorable half-lives (t_1/2s) of 3.3 and 3.1 h for i.v. and oral, respectively. The oral bioavailability (F_po) in this study is 27%^[1].
