PD0332991 Isethionate Chemical Properties,Usage,Production
Uses
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
Biological Activity
cyclin-dependent kinases (cdks) are a family of protein kinases first discovered for their role in regulating the cell cycle. they are also involved in regulating transcription, mrna processing, and the differentiation of nerve cells. a cyclin-dependent kinase inhibitor (cki) is a protein that interacts with a cyclin-cdk complex to block kinase activity, usually during g1 or in response to signals from the environment or from damaged dna. palbociclib is an experimental drug for the treatment of breast cancer being developed by pfizer. it is a selective inhibitor of the cyclin-dependent kinases cdk4 and cdk6.
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.
in vitro
half-maximal inhibitory concentrations (ic50) of pd-0332991 were determined with cell line proliferation assays. resutls showed that ic50 values for pd-0332991 ranged from 25.0 nm to 700 nm, and the agent demonstrated g0/g1 cell-cycle arrest, induction of late apoptosis, and blockade of rb phosphorylation. through genotype and expression data p16, p15 and e2f1 were identified as having significant association between loss and sensitivity to pd-0332991: p16 (p=0.021), p15 (p=0.047), and e2f1 (p=0.041) [1].
in vivo
oral administration of pd 0332991 to mice bearing the colo-205 human colon carcinoma produces marked tumor regression. therapeutic doses of pd 0332991 cause elimination of phospho-rb and the proliferative marker ki-67 in tumor tissue and down-regulation of genes under the transcriptional control of e2f. the results indicate that inhibition of cdk4/6 alone is sufficient to cause tumor regression and a net reduction in tumor burden in some tumors [2].
target
CDK4
IC 50
palbociclib is an orally active, potent and highly selective inhibitor of cdk4 and cdk6, with ic50 values for cdk4/cyclind1, cdk4/cyclind3 and cdk6/cyclind2 of 11, 9 and 15 nmol/l, respectively.
