Application

PHA 767491 hydrochloride has been used to study its effect on estrogen-induced DNA damage. It has also been used in western blot analysis and to study the S9.6 nuclear signal in HeLa cells.

Biochem/physiol Actions

PHA 767491 serves as a potential anticancer drug. It shows an ameliorating effect against acute myeloid leukemia, colon and breast cancer models. PHA 767491 possesses anti proliferating and apoptotic effect.
PHA-767491 is a potent and selective ATP-competitive dual inhibitor cdc7/cdk9. PHA-767491 blocks DNA synthesis and affects the phosphorylation of the replicative DNA helicase at Cdc7-dependent phosphorylation sites.

Lesions on DNA uncouple DNA synthesis from the replisome, generating stretches of unreplicated single-stranded DNA (ssDNA) behind the replication fork. These ssDNA gaps need to be filled in to complete DNA duplication. Gap-filling synthesis involves either translesion DNA synthesis (TLS)
