Sam Jin is investigating SJ-3366, a non-nucleoside reverse transcriptase inhibitor (NNRTI), for the potential treatment of HIV infection [302450]. As well as acting as an NNRTI, SJ-3366 also interferes with HIV-1 entry via an intermediate target formed after virus-cell attachment [341146], [363900]. As of June 1998, Sam Jin had been awarded a patent for SJ-3366 in South Africa, with applications pending in 22 other countries [302450].
