Molarity Calculator

Trilaciclib (G1T28) hydrochloride is an orally active CDK4/6 inhibitor with IC50 values of 1 nM and 4 nM for CDK4 and CDK6, respectively. Trilaciclib hydrochloride can effectively inhibit tumor cell proliferation and reduce the hematological toxicity caused by chemotherapy. Trilaciclib hydrochloride attenuates apoptosis and myelosuppression induced by 5FU (HY-90006) chemotherapy.

Description

Trilaciclib (G1T28) hydrochloride is an orally active CDK4/6 inhibitor with IC50 values of 1 nM and 4 nM for CDK4 and CDK6, respectively. Trilaciclib hydrochloride can effectively inhibit tumor cell proliferation and reduce the hematological toxicity caused by chemotherapy. Trilaciclib hydrochloride attenuates apoptosis and myelosuppression induced by 5FU (HY-90006) chemotherapy[1].

IC50 & Target[1]

Cdk4/cyclin D1

1 nM (IC50)

cdk6/cyclin D3

4 nM (IC50)

In Vitro

Trilaciclib hydrochloride (10-1000 nM; 24 h) reversibly modulates the proliferation of mouse and canine bone marrow hematopoietic stem and progenitor cells[1].
Trilaciclib hydrochloride (10-1000 nM; 24 h) can arrest the cell cycle of CDK4/6-dependent cells in the G1 phase, with an EC50 of 30 nM for HS68[1].
Trilaciclib hydrochloride (300 nM; 16 or 48 h) protects CDK4/6 dependent cells (HS68, WM2664) from chemotherapy-induced damage, and attenuates chemotherapy-induced-apoptosis[1].

Cell Proliferation Assay[1]

Cell Line: HS68, WM2664 cells
Concentration: 300 nM
Incubation Time: 8h for measure γH2AX foci (DNA damage); 48 hours to measure caspase 3/7 activity (apoptosis).
Result: Elicited a robust dose-dependent decrease in caspase 3/7 activation suggesting an attenuation of apoptosis.
Resulted a dose-dependent decrease in γH2AX foci in all DNA damaging chemotherapies tested (carboplatin, doxorubicin, etoposide, camptothecin).

Cell Cycle Analysis[1]

Cell Line: HS68, WM2664 cells
Concentration: 10, 30, 100, 300, 1000 nM
Incubation Time: 24 h
Result: Inhibited only CDK4/6-dependent cells, with EC50 of 30 nM for HS68 cell.
Singnificantly decreased the S phase cell numbers, increased the G1 phase cell numbers.

Western Blot Analysis[1]

Cell Line: HS68, WM2664 cells
Concentration: 10, 30, 100, 300, 1000 nM
Incubation Time: 16 h
Result: Blocked RB phosphorylation in the RB dependent cell lines by 16 hours post exposure, while the CDK4/6-independent cell line (A2058) exhibits no RB or pRB expression. Suggesting an attenuation of chemotherapy-induced DNA damag
In Vivo

Trilaciclib hydrochloride (50-150 mg/kg; po; single dose) protects mouse bone marrow cells from chemotherapy-induced apoptosis and attenuates chemotherapy-induced myelosuppression in vivo. Trilaciclib hydrochloride at 150 mg/kg reduces HSPC damage induced by 5FU (150 mg/kg; ip) chemotherapy, thereby accelerating blood count recovery after chemotherapy[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: FVB/n female C57Bl6 mice[1]
Dosage: 50, 100, 150 mg/kg
Administration: Po; single dose; treated followed 11 or 23 hours later by a single injection of EdU (HY-118411) (100 μg; ip); mouse were euthanized 1 hour after EdU injection.
Result: Showed a dose-dependent decrease in caspase 3/7 activation.
Attenuated chemotherapy-induced myelosuppression in mice.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
