PHA-793887

White to Off-White Solid

PHA-793887 is a potent CDK (cyclin-dependent kinase) inhibitor. Recent studies shows that PHA-793887 has promising therapeutic activity against acute leukemias in vitro and in vivo. PHA-793887 was used to successfully modulate E2F transcriptional factor-dependent cell cycle, DNA replication, mitosis and apoptosis related gene in both tumors and skin biopsy from patients with solid tumors.

ChEBI: N-[6,6-dimethyl-5-[(1-methyl-4-piperidinyl)-oxomethyl]-1,4-dihydropyrrolo[3,4-c]pyrazol-3-yl]-3-methylbutanamide is a piperidinecarboxamide.

PHA-793887 is a highly potent and selective pan-CDK inhibitor (CDK1/2//4/5/7/9 IC50 5-140 nM; IC50 >10 μM against 34 other kinases) with anti-proliferative activity against several solid tumor cell lines (IC50 <1 μM) by blocking Rb phosphorylation and the expression of S-phase cyclins, such as cyclin A. PHA-793887 exhibits in vivo anti-leukemia efficacy in murine xenograft models (20 mg/kg via daily i.v.; HL60, K562, ALL-2 or AML-PS).
