Lerociclib (G1T38) is a selective and highly potent CDK4/6 inhibitor with anticancer and antitumor activity, inhibits CDK4/CyclinD1 and CDK6/CyclinD3, and inhibits tumor growth in an animal model of endocrine-resistant breast cancer. Due to the poor solubility, for animal studies, the salt form T11345L is recommended.

| In vitro | Lerociclib is highly potent and selective for CDK4/cyclin D1 and CDK6/cyclin D3 over CDK1, CDK2, CDK5 and CDK7 and their respective binding partners. Lerociclib produced a robust and sustained G1 arrest in CDK4/6 dependent cells with an EC50 of ~20 nmol/L. [1] |
| In vivo | To evaluate the murine PK/PD relationship of Lerociclib, an ER+ MCF7 xenograft model was utilized. Compound concentrations were measured in plasma and tumors from tumor-bearing mice given a single oral dose of Lerociclib (100 mg/kg). Oral Lerociclib has sufficient mouse PK/PD for assessing efficacy in tumor models. [1] |
