General description

A cell-permeable and highly selective inhibitor of cyclin-dependent protein kinases (Cdks) that inhibits cell cycle progression at the G1/S and G2/M transitions. Inhibits p34cdk1/cyclinB (Cdk1; IC50 = 680 nM). Also selectively inhibits Cdk2 and Cdk5 kinases. Has little effect on casein kinase I, casein kinase II, EGF receptor kinase, MAP kinase, PKA, and PKC. Shown to prevent the phosphorylation of retinoblastoma protein and H1 histone. Also blocks Fas-induced apoptosis in HL-60 cells and shows antitumor effects on human lung cancer cell lines.

Hematopoietic stem cells (HSCs) reside in the bone marrow (BM) niche, which includes bone-forming and bone-resorbing cells, i.e., osteoblasts (OBs) and osteoclasts (OCs). OBs originate from mesenchymal progenitors, while OCs are derived from HSCs. Self-renewal, proliferation and differentiation of HSCs
