Some anti-inflammatory molecules are also known to possess anti-human immunodeficiency virus (HIV) activity. We found that o-(acetoxyphenyl)hept-2-ynyl sulfide (APHS), a recently synthesized non-steroidal anti-inflammatory molecule can inhibit HIV-1 replication. The aim of this study was to clarify the mechanism of action of APHS. When administered during the first steps of the infection, APHS was capable of inhibiting the replication of several HIV-1 strains (macrophage-tropic and/or lymphocytotropic) in a dose-dependent manner in both peripheral blood mononuclear cells (PBMC), monocyte-derived macrophages and peripheral blood lymphocytes with 50% inhibitory concentration values of approximately 10 microM. The 50% toxic concentration of APHS varied between 100 and 200 microM in the different primary cells tested. APHS did not affect HIV-1 replication once the provirus was already inserted into the cellular genome. APHS also did not inhibit HIV-1 entry into the host cells as determined by quantification of gag RNA inside PBMC 2h after infection. However, APHS did inhibit gag DNA synthesis during reverse transcription in primary cells, which indicates that APHS may target the reverse transcription process.

UI	MeSH Term	Description	Entries
D007963	Leukocytes, Mononuclear	Mature LYMPHOCYTES and MONOCYTES transported by the blood to the body's extravascular space. They are morphologically distinguishable from mature granulocytic leukocytes by their large, non-lobed nuclei and lack of coarse, heavily stained cytoplasmic granules.	Mononuclear Leukocyte,Mononuclear Leukocytes,PBMC Peripheral Blood Mononuclear Cells,Peripheral Blood Human Mononuclear Cells,Peripheral Blood Mononuclear Cell,Peripheral Blood Mononuclear Cells,Leukocyte, Mononuclear
D008214	Lymphocytes	White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS.	Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
D008264	Macrophages	The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.
