Overview

Information

G1T38 (Lerociclib) is a novel, potent, selective, and orally bioavailableCDK4/6inhibitor with IC50 values of 0.001 μM, 0.002 μM and 0.028 μM for CDK4, CDK6 and CDK9 respectively.

Targets

CDK4 (Cell-free assay); CDK6 (Cell-free assay); CDK9 (Cell-free assay) 1 nM; 2 nM; 28 nM

In vitro

G1T38 is highly potent and selective for CDK4/cyclin D1 and CDK6/cyclin D3 over CDK1, CDK2, CDK5 and CDK7 and their respective binding partners. G1T38 decreases RB1 (RB) phosphorylation, causes a precise G1 arrest, and inhibits cell proliferation in a variety of CDK4/6-dependent tumorigenic cell lines including breast, melanoma, leukemia, and lymphoma cells with EC50 concentrations as low as 23 nM.

In vivo

G1T38 treatment leads to equivalent or improved tumor efficacy compared to the first-in-class CDK4/6 inhibitor, palbociclib, in an ER+ breast cancer xenograft model. Furthermore, G1T38 accumulates in mouse xenograft tumors but not plasma, resulting in less inhibition of mouse myeloid progenitors than after palbociclib treatment. In larger mammals, this difference in pharmacokinetics allows for 28 day continuous dosing of G1T38 in beagle dogs without producing severe neutropenia.
