How to use

In Vitro:

Incubation with Trilaciclib hydrochloride (G1T28) for 24 hours induces a robust G1 cell-cycle arrest (time=0). By 16 hours after Trilaciclib hydrochloride washout, cells have reentered the cell cycle and demonstrate cell-cycle kinetics similar to untreated control cells. These results demonstrate that Trilaciclib hydrochloride causes a transient, and reversible G1 arrest. A transient Trilaciclib hydrochloride-mediated G1 cell-cycle arrest in CDK4/6-sensitive cells decreases the in vitro toxicity of a variety of commonly used cytotoxic chemotherapy agents associated with myelosuppression.

In Vivo:

Trilaciclib hydrochloride (G1T28) treatment results in a robust and dose-dependent suppression of proliferation in HSPCs at 12 hours, with 5-ethynyl-2′-deoxyuridine (EdU) incorporation returning near baseline levels in a dose-dependent manner by 24 hours after administration. These data demonstrate that a single oral dose of Trilaciclib hydrochloride can produce reversible cell-cycle arrest in HSPCs in a dose-dependent manner in vivo. Mice given 100 mg/kg Trilaciclib hydrochloride 30 minutes prior to etoposide treatment, exhibits only background levels of caspase-3/7 activity. These data demonstrate that Trilaciclib hydrochloride can protect the bone marrow from chemotherapy-induced apoptosis in vivo. The data demonstrate that treatment with Trilaciclib hydrochloride prior to 5-fluorouracil (5-FU) likely decreases 5-FU-induced damage by chemotherapy in HSPCs, thus accelerating blood count recovery after chemotherapy.
