Description

Application

PD 0332991 isethionate has been used:

• to incubate MCF10A cells to verify cyclin D1 inhibition of autophagy involved cyclin-dependent kinase activity
• as a cyclin dependent kinase 4 (CDK4) inhibitor to study its anticonvulsive property in Drosophila
• to mimic the inhibitory effect of 5α-dihydrotestosterone (DHT) on HPr-1AR cell cycle progression and growth

Biochem/physiol Actions

PD 0332991 is a potent selective inhibitor of cyclin dependent kinases CDK4 and CDK6 with in vitro IC₅₀ = 11 nM (CDK4) and 16 nM (CDK6). PD 0332991 induces G1 arrest in retinoblastoma (Rb)-positive tumor cells.

PD 0332991 might act as a chemsensitizer. It is useful in the treatment of breast cancer along with antioestrogens. PD 0332991 is also known to possess antitumor action.
