PF-07104091 is an orally bioavailable inhibitor of cyclin-dependent kinase 2 (CDK2), with potential antineoplastic activity. Upon administration, CDK2 inhibitor PF-07104091 selectively targets, binds to and inhibits the activity of CDK2. This may lead to cell cycle arrest, the induction of apoptosis, and the inhibition of tumor cell proliferation. CDKs are serine/threonine kinases that are important regulators of cell cycle progression and cellular proliferation and are frequently overexpressed in tumor cells. CDK2/cyclin E complex plays an important role in retinoblastoma (Rb) protein phosphorylation and the G1-S phase cell cycle transition. CDK2/cyclin A complex plays an important role in DNA synthesis in S phase and the activation of CDK1/cyclin B for the G2-M phase cell cycle transition.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
