PHA-793887 is an inhibitor of multiple cyclin dependent kinases (CDK) with activity against CDK2, CDK1 and CDK4. PHA-793887 was cytotoxic for leukemic cell lines in vitro, with IC(50) ranging from 0.3 to 7 uM. In colony assays PHA-793887 showed very high activity against leukemia cell lines, with an IC(50) <0.1 uM indicating that it has efficient and prolonged antiproliferative activity. PHA-793887 induced cell-cycle arrest, inhibited Rb and nucleophosmin phosphorylation. PHA-793887 has promising therapeutic activity against acute leukemias in vitro and in vivo.

Sample Use Guides

Mice: PHA-793887 was administered at 20 mg/kg intravenous (IV) once a day, continuously for 10 days (from day 9 to day 18) in HL60 model and with a two 5-day cycles (from day 9 to day 13 and from day 17 to day 21) in K562-bearing mice.
Route of Administration: Oral
PHA-793887 was cytotoxic for leukemic cell lines in vitro, with IC(50) ranging from 0.3 to 7 uM (mean: 2.9 uM). in colony assays PHA-793887 showed very high activity against leukemia cell lines, with an IC(50) <0.1 uM (mean: 0.08 uM). PHA-793887 induced cell-cycle arrest, inhibited Rb and nucleophosmin phosphorylation, and modulated cyclin E and cdc6 expression at low doses (0.2-1 uM) and induced apoptosis at the highest dose (5 uM).
