ADDRESS: Requests for a copy of these patents, inquiries, comments, and other materials relating to the contemplated license should be directed to: J. Peter Kim, Technology Licensing Specialist, Office of Technology Transfer, National Institutes of Health, 6011 Executive Boulevard, Suite 325, Rockville, Maryland 20852-3804; Telephone: (301) 496-7056, ext. 264; Facsimile: (301) 402-0220.
SUPPLEMENTARY INFORMATION: The present invention relates to a method of treating retroviral infections in mammals via the use of an effective amount of topoisomerase I inhibitor such as camptothecin (CPT) and similar compounds which act as inhibitors of retroviral topoisomerase I, blocking both the initiation of retroviral infection and replication in target cells. As a consequence of this mechanism of action, use of such inhibitors provides a potential means of reducing or eliminating retroviral
