Olverembatinib (GZD824) dimesylate is a potent and orally active pan-Bcr-Abl inhibitor. Olverembatinib dimesylate potently inhibits a broad spectrum of Bcr-Abl mutants. Olverembatinib dimesylate strongly inhibits native Bcr-Abl and Bcr-AblT315I with IC50s of 0.34 nM and 0.68 nM, respectively. Olverembatinib dimesylate has antitumor activity.IC50 & Target:IC50: 0.68 nM (Bcr-AblT315I), 0.27 nM (Bcr-AblE255K) , 0.71 nM (Bcr-AblG250E) , 0.15 nM (Bcr-AblQ252H), 0.35 nM (Bcr-Abl H396P), 0.29 nM (Bcr-Abl M351T), 0.35 nM (Bcr-AblY253F), Bcr-AblF317LIn Vitro: Olverembatinib dimesylate shows antiproliferative activity in stably transformed Ba/F3 cells whose growth was driven by native Bcr-Abl or Bcr-Abl mutants.
Olverembatinib dimesylate selectively and potently inhibits the proliferation of Bcr-Abl-positive leukemia cells.
Olverembatinib dimesylate inhibits Bcr-Abl signaling in K562 (1-20 nM; 4.0 hours) and Ba/F3 stable cell lines expressing native Bcr-Abl (0.1-100 nM; 4.0 hours) or Bcr-AblT315I(0.1-100 nM; 4.0 hours).
In Vivo: Olverembatinib dimesylate suppresses tumor growth in mice bearing allografted Ba/F3 cells expressing Bcr-Abl WT.
Olverembatinib dimesylate (1-20 mg/kg; i.g.; daily; for 10 days) significantly increases the median survival of the mice bearing allografted Ba/F3 cells expressing Bcr-AblT315I.
Olverembatinib dimesylate exhibits a good oral bioavailability (rat 48.7%) and Cmax (rat 390.5 μg/L) following oral administration (rat; 25 mg/kg).
Olverembatinib dimesylate exhibits terminal elimination half-lives (rat 5.6 h) due to high plasma clearance (rat 1.7 L/h/kg) following intravenous administration (rat 5 mg/kg).
