Suppression of HIV-1 replication in peripheral blood mononuclear cells by fasudil

Fasudil is a potent inhibitor for various protein kinases such as myosin light chain kinase and protein kinase C. It has been used as a drug for improvement of intracranial vasospasm and following ischaemic diseases. In this report, we demonstrate that fasudil suppressed the replication of human immunodeficiency virus type 1 (HIV-1) in mitogen-activated peripheral blood mononuclear cells. Our finding shows that fasudil may be useful as a new and distinct chemotherapeutic agent against HIV-1 infection.
