Biological Activity

Description Palbociclib (PD 0332991) is a highly specific inhibitor of cyclin-dependent kinase 4 (Cdk4) and Cdk6 with IC50 of 11 nM and 16 nM, respectively.This product has poor solubility, animal experiments are available, cell experiments please choose carefully!
Targets
Cdk4 [1]
(Cell-free assay)
Cdk6 [1]
(Cell-free assay)
11 nM 16 nM
In vitro

Palbociclib, a CKD4/6 inhibitor, significantly reduces HR+/HER2+ tumor cell viability when combinates with tucatinib and fulvestrant.[2]

In vivo

Palbociclib, a CKD4/6 inhibitor, shows superior efficacy in suppression of tumor growth in vivo when combinates with tucatinib and fulvestrant.[2]

Protocol (from reference)

Cell Assay:

[2]

  • Cell lines

    BT474 and MDA-MB-361 tumor cell lines

  • Concentrations

    0-15 μM

  • Incubation Time

    72 h

  • Method

    Cell viability is measured by Cell Titer Glo assay after 72 hours of treatment with vehicle or drugs. For all experiments with fulvestrant, cells are grown in estrogen free conditions, and estradiol is added to a final concentration of 10-8 M prior to drug treatment. Palbociclib, fulvestrant, and tucatinib IC30 values are calculated for each cell line, and the IC30 concentrations are used for subsequent experiments.

Animal Study:

[2]

  • Animal Models

    NCG mice injected with MDA-MB-361 cells

  • Dosages

    50mg/kg

  • Administration

    o.g.
