    Discovery of targeted therapies for cancer patients: CDK2/4/6 inhibitor Ebvaciclib and EZH2 inhibitor PF-06821497 (ACS-Fall 2023)
    Ebvaciclib, is a CDK2/4/6 inhibitor designed to be co-dosed with hormone therapy (letrozole or fulvestrant) to treat HR+ breast cancer. PF-06821497 is an EZH2 inhibitor currently being evaluated alone and in combination with enzalutamide to treat patients with castration resistant prostate cancer who have received either abiraterone and/or enzalutamide treatment and have evidence of prostate cancer progression. Discovery, synthesis, and early clinical results will be presented.

    Expanding control of the tumor cell cycle with a CDK2/4/6 inhibitor. (PubMed, Cancer Cell)
    The CDK4/6 inhibitor, palbociclib (PAL), significantly improves progression-free survival in HR/HER2 breast cancer when combined with anti-hormonals...We describe the pharmacodynamics and efficacy of PF-06873600 (PF3600), a pyridopyrimidine with potent inhibition of CDK2/4/6 activity and efficacy in multiple in vivo tumor models...Finally, we find that CDK2/4/6 inhibition does not compromise tumor-specific immune checkpoint blockade responses in syngeneic models. We anticipate that (PF3600), currently in phase 1 clinical trials, offers a therapeutic option to cancer patients in whom CDK4/6 inhibition is insufficient to alter disease progression.

    Discovery of PF-06873600, a CDK2/4/6 Inhibitor for the Treatment of Cancer. (PubMed, J Med Chem)
    Further, we detail the use of molecular dynamics simulations to provide insights into the basis for selectivity against CDK9. Based on overall potency, selectivity, and ADME profile, PF-06873600 (22) was identified as a candidate for the treatment of cancer and advanced to phase 1 clinical trials.
