生物活性:
FIT-039 is a selective, ATP-competitive and orally active CDK9 inhibitor with an IC50 of 5.8 μM for CKD9/cyclin T1. FIT-039 does not inhibit other CDKs and other kinases. FIT-039 inhibits replication of HSV-1 (IC50 of 0.69 μM), HSV-2, human adenovirus, and human CMV. FIT-039 is a promising antiviral agent for inhibiting drug-resistant HSVs and other DNA viruses.

体内研究:
Treatment with the FIT-039 ointment twice a day suppresses skin lesions and rescues mice (male BALB/c mice injected with HSV-1) from lethality in a dose-dependent manner. The healing of lesions is observed with 5% to 10% FIT-039 ointment, leading to the complete regression of zosteriform spread on day 10, which is also observed with the 5% ACV ointment.FIT-039 does not affect body weight gain in mice administrated with an overdose of this compound (1000 mg/kg/d) for 14 days, and no changes are observed in biological markers in their blood.

体外研究:
FIT-039 (30 μM; 3 hours; HEK293 cells) treatment decreases phosphorylated CTD in the infected or noninfected cells to a level lower than that shown by Flavopiridol. FIT-039 reduces the expression levels of HSV-1 immediate-early genes (IEGs) and early and late genes.FIT-039 inhibits replication of the HSV-1 genome in a dose-dependent manner (EC50 and EC80 are 0.69 μM and 4.0 μM, respectively).FIT-039 potently suppresses 8 kinases (GSK3β, PKN1, haspin, p70s6K, DYRK1B, GSK3α, IRR, and DYRK3) other than CDK9 on the 332-kinase panel. These kinases are involved in the replication of various viruses.
