title: Estramustine phosphate reversibly inhibits an early stage during adenovirus replication.
abstract: Estramustine phosphate, an estradiol-mustard conjugate, was shown to reversibly inhibit a stage during the first hour of productive adenovirus 2 infection of HeLa cells. This drug, employed in the therapy of advanced prostatic cancer, specifically interacts with microtubule-associated proteins (MAPs) of the cytoskeleton. The results obtained under physiological conditions in vivo suggest a MAPs-interference with the microtubule-mediated vectorial migration of the virus inoculum to the nucleus. Virus attachment, uncoating kinetics and the appearance of established uncoating intermediates were not affected.
