Abstract Background The positive transcription elongation factor b P-TEFb is an essential cellular cofactor for the transcription of the human immunodeficiency virus type 1 HIV-1 . The cyclin T1 CycT1 subunit of P-TEFb associates with a viral protein Tat at the transactivation response element TAR . This represents a critical and necessary step for the stimulation of transcriptional elongation. Therefore CycT1 may serve as a potential target for the development of anti-HIV therapies. Results To create effective inhibitors of HIV transcription
