Imperatorin is a furocoumarin present in citrus fruits, which is used in HIV-1 research. Studies indicate that the transcription factor Sp1 is essential in the inhibitory functions of Imperatorin. In addition, Imperatorin inhibits cyclin D1 expression and stops the cell cycle at G1. These studies also suggest that Imperatorin suppresses HIV-1 replication in primary T lymphocytes and transformed cell lines. Furthermore, it has been suggested that the inhibitory effects of Imperatorin on HIV-1 at the transcriptional level can be monitored effectively in HeLa cells. Imperatorin can also cause apoptosis in human promyelocytic leukaemia, HL-60 via the cytochrome c/caspase-9 pathway.
