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

Description

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

IC50 & Target

IC50: 1 nM (CDK4), 4 nM (CDK6)[1]
In Vitro

Trilaciclib (10-1000 nM; 24 h) reversibly modulates the proliferation of mouse and canine bone marrow hematopoietic stem and progenitor cells[1].
Trilaciclib (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 (300 nM; 16 or 48 h) protects CDK4/6 dependent cells (HS68, WM2664) from chemotherapy-induced damage, and attenuates chemotherapy-induced-apoptosis[1].

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

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: Produced a strong dose-dependent inhibition of HSPC proliferation within 12 hours.
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).

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

Cell Cycle Analysis[1]

Cell Line: HS68, WM2664 cells
Concentration: 300 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.
In Vivo

Trilaciclib (50-150 mg/kg; po; single dose) protects mouse bone marrow cells from chemotherapy-induced apoptosis and attenuates chemotherapy-induced myelosuppression in vivo. Trilaciclib at 150 mg/kg reduces HSPC damage induced by 5FU (HY-90006) (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.
