pd-0332991

Palbociclib (PD 0332991) is a CDK inhibitor that inhibits CDK4 and CDK6 (IC50=11 16 nM) and is orally active. Palbociclib has anti-tumorigenic activity and has investigational potential for use in ER-positive and HER2-negative breast cancer.

Palbociclib Isethionate (PD 0332991 isethionate) is a selective inhibitor of CDK4 6 (IC50s: 11 16 nM). It exhibits no inhibition against a panel of 36 additional protein kinases.

Palbociclib monohydrochloride (PD 0332991 hydrochloride) is a selective inhibitor of CDK4 6 (IC50s: 11 16 nM). It exhibits no inhibition against a panel of 36 additional protein kinases.

Palbociclib (PD 0332991) dihydrochloride is an orally active, selective inhibitor of CDK4 (IC50: 11 nM) and CDK6 (IC50: 16 nM), exhibiting anti-proliferative activity and inducing cell cycle arrest in HR-positive and HER2-negative breast cancers and hepatocellular carcinoma studies.

Palbociclib-d8 (PD 0332991 D8) is the 2H-labeled form of Palbociclib. Palbociclib is an orally active CDK inhibitor that inhibits CDK4 and CDK6 (IC50=11 16 nM). Palbociclib has anti-tumor activity and is used in research for estrogen receptor-positive and HER2-negative breast cancer.

N-Methyl Palbociclib is an impurity of the orally active, selective CDK4 and CDK6 inhibitor Palbociclib (PD 0332991).

Palbociclib hydrochloride (pabociclib hydrochloride) is the salt form of Palbociclib, a selective and orally available CDK4 and CDK6 inhibitor with anti-tumor proliferative activity for use in breast and hepatocellular carcinoma.

PD 0332991, an unsymmetrical indolocarbazole compound, is cell-permeable and exhibits antiproliferative effects by functioning as a potent, selective, reversible, and ATP-competitive inhibitor of Cdk4/D1 (IC 50 = 76 nM). Although it can inhibit other Cdks, such as Cdk2/E and Cdk1/B, effectiveness requires higher concentrations (IC 50 = 520 nM and 2.1 µM, respectively) and demonstrates minimal activity against CaMKII, PKA, or GSK-3β (IC 50 ≥ 12.4 µM). PD 0332991 efficiently inhibits tumor cell growth in HCT-116 and NCI-H460 cell lines with an IC 50 < 3.0 µM, primarily through blocking Rb phosphorylation and inducing G1 cell cycle arrest.

Palbociclib (PD 0332991) orotate, an orally active selective inhibitor of CDK4 and CDK6, exhibits IC50 values of 11 and 16 nM, respectively. This compound demonstrates potent anti-proliferative effects and induces cell cycle arrest in cancer cells, applicable in research concerning HR-positive, HER2-negative breast cancer, and hepatocellular carcinoma [1] [3] [4].

Palbociclib-SMCC is a Palbociclib derivative with a SMCC linker.
