Characterize the anti-HIV-1 activity of a kinase inhibitor kenpaullone and the HIV-1 integrase association with DIC1 and DYNLT1
Advances in the antiretroviral therapy (ART) have dramatically reduced the death rate from human immunodeficiency virus type 1 (HIV-1) induced acquired immune deficiency syndrome (AIDS). However, it is still necessary to develop anti-HIV-1 new drugs. In this study, two projects were conducted and may contribute to the new drug development. The first project is focused on characterizing the anti-HIV activity of a kinase inhibitor Kenpaullone (Ken). We found a cyclin dependent kinase (CDK) and glycogen synthase kinase-3β (GSK-3β) inhibitor named Ken can significantly inhibit HIV-1 replication. Mechanistic analysis by RT-PCR revealed that Ken inhibited HIV-1 replication by disrupting transcription possibly through CDK-dependent pathways. The second project is focused on understanding the association between HIV-1 integrase (IN) and dynein components. Our investigation indicated that HIV-1 IN is associated with DIC1 and DYNLT1. Further investigation this IN/dynein component association may help to reveal new anti-HIV targets.
