Background

FIT-039 is an inhibitor of cyclin-dependent kinase 9 (Cdk9; IC₅₀ = 5.8 ?M for Cdk9/cyclin T1).¹ It is selective for Cdk9/cyclin T1 over Cdk4/cyclin D3 at 30 ?M and Cdk2/cyclin A2, Cdk2/cyclin E1, Cdk5/p25, Cdk6/cyclin D3, and Cdk7/cyclin/MAT1 at 10 ?M but also inhibits GSK3α, GSK3β, PKN1, haspin, p70S6K, DYRK1B, DYRK3, and IRR at 10 ?M. FIT-039 inhibits DNA replication of herpes simplex virus 1 (HSV-1) in HeLa cells (IC₅₀ = 0.69 ?M). Topical application of FIT-039 (1.25-10% w/w) reduces skin lesions and improves survival in HSV-1-infected mice. FIT-039 (300 mg/kg) also reduces tumor growth in a human papillomavirus (HPV) type 16-positive Ca Ski cervical cancer mouse xenograft model.²
