Definitions
- the present invention relates to a new family of compounds having anti-inflammatory, and anti-viral, and broncho-dilating activity which, additionally, in combination with a reverse transcriptase inhibitor results in an additive or synergistic effect which is useful in inhibiting or suppressing retroviral replication or eliminating a retrovirus in a human cell population.
- HIV Human Immunodeficiency Virus
- part of the reverse transcription process also can occur in unactivated T cells, a process that results in the accumulation of incomplete DNA molecules, which may persist for several hours and remain capable of being integrated into the host genome if the cell undergoes sufficient activation (Zack J.A, et al. , Cell. 1990; 61: 213-222) . Therefore, infected "resting" CD4+T lymphocytes can be considered a transient viral reservoir in infected individuals (Bukrinsky M.I, et al. Science. 1991; 254: 423-427), and a high HIV burden has also been observed in lymphoid tissue as intracellular virus in latent form (Embretson J, et al., Nature. 1993; 362: 359- 362) .
