Description: Palbociclib isethionate(PD-0332991 isethionate) is a highly specific inhibitor of Cdk4 (IC50=11 nM) and Cdk6 (IC50=16 nM), having no activity against a panel of 36 additional protein kinases.
In Vivo: Palbociclib(150 mg/kg. p.o.) produces rapid Colo-205 colon carcinoma xenografts regressions and a corresponding tumor growth delay. Palbociclib (150 mg/kg, p.o.) induces complete tumor stasis and cell kill in MDA-MB-435 breast carcinoma. Palbociclib (150 mg/kg) also induces significant tumor regression in mice bearing the SF-295 glioblastoma xenografts, and in ZR-75-1 breast and PC-3 prostate tumor models (complete suppression of tumor growth). Palbociclib (150 mg/kg) suppresses Rb Ser780 phosphorylation in MDA-MB-435 breast carcinoma over the full 24-hour period. Palbociclib (150 mg/kg) down-regulates expression of four E2F-regulated genes CDC2, CCNE2, TK1, and TOP2A in Colo-205 carcinoma xenografts[1]. Palbociclib also rapidly inhibits myeloma tumor growth[2].
In Vitro: Palbociclib exhibits absolute selectivity for CDK4/6 with little or no activity against other CDKs. Palbociclib is effective at reducing Rb phosphorylation at Ser780 and Ser795 in MDA-MB-435 breast carcinoma cells with IC50 of 66 nM and 63 nM, respectively. Palbociclib is a potent inhibitor of cell growth and suppresses DNA replication by preventing cells from entering S phase. Palbociclib inhibits thymidine incorporation into the DNA of Rb-positive human breast (such as MDA-MB-435, MCF-7), colon (H1299), and lung carcinomas (Colo-205) as well as human leukemias (CRRF-CEM and K562), with IC50 values ranging from 0.04-0.17 μM. Palbociclib significant increases the percentage of MDA-MB-453 in G1 period[1]. Palbociclib inhibits phosphorylation of Rb in cycling CD138+ primary bone marrow myeloma cells, nontransformed primary B cells, MM1.S and CAG HMCLs cells line with IC50 of <0.1 μM, 0.05 μM, and 60-70 nM, respectively. Palbociclib treatment also induces G1 arrest of CD138+ primary bone marrow myeloma and nontransformed primary B cells. Palbociclib induces G1 arrest in MM1.S with IC50 of appr 0.05 μM[2]. Palbociclib preferentially inhibits proliferation of luminal estrogen receptor-positive (including HER2-positive) human breast cancer cell lines. Palbociclib increases gene expression of pRb and cyclin D1 and decreases gene expression of CDKN2A (p16) in most sensitive lines. Palbociclib enhances sensitivity to tamoxifen in cell lines with conditioned resistance to ER blockade[3].

DC27001 SR-4835 SR-4835 is a highly selective dual inhibitor of CDK12 and CDK13.
DC70595 MFH290 MFH290 (MFH-290) is a potent, highly selective, covalent inhibitor of CDK12/13 with IC50 of 25/49 nM.MFH290 forms a covalent bond with Cys-1039 of CDK12, and CDK12-dependent as mutation of Cys-1039 rendered the kinase refractory to MFH290.MFH290 exhibits excellent kinome selectivity, inhibits the phosphorylation of serine-2 in the C-terminal domain (CTD) of RNA-polymerase II (Pol II), and reduces the expression of key DNA damage repair genes.MFH290 restored Pol II CTD phosphorylation and DNA damage repair gene expression AND augments the antiproliferative effect of the PARP inhibitor olaparib.
DC50184 dCeMM3 dCeMM3 (Compound 3) is a glue degrader. dCeMM3 induces ubiquitination and degradation of cyclin K by prompting an interaction of CDK12-cyclin K with a CRL4B ligase complex.
DC49082 CDK5-IN-2 CDK5-IN-2 (compound 15) is a highly selective CDK5 inhibitor with IC50s of 0.2 and 23 for CDK5/p25 and CDK2/CycA, respectively.
