Abstract As part of a continued search for more efficient anti-HIV-1 drugs we are focusing on the possibility that small molecules could efficiently inhibit HIV-1 replication through the restoration of p53 and p21WAF1 functions which are inactivated by HIV-1 infection. Here we describe the molecular mechanism of 9-aminoacridine 9AA mediated HIV-1 inhibition. 9AA treatment resulted in inhibition of HIV LTR transcription in a specific manner that was highly dependent on the presence and location of the amino moiety. Importantly virus replication was found to be inhibited .
