Nigranoic acid 

Nigranoic acid is a triterpenoid separated from Schisandra chinensis. Nigranoic acid inhibits HIV-1 reverse transcriptase. Nigranoic acid exhibits protective effects on brain through PARP/AIF signaling pathway in cerebral ischemia-reperfusion animal model^[1][2].

HIV-1 reverse transcriptase

Nigranoic acid has a strong protective effect on rat cerebral ischemia-reperfusion injury, and acts by downregulating nerve cell apoptosis by preventing the overactivation of PARP and AIF nuclear translocation^[2].
Nigranoic acid (1 mg/kg; i.g.; 6 hours and 2 hours before brain ischemia) significantly decreases apoptosis and the expression levels of AIF protein, PARP protein, and AIF mRNA at different time-points^[2].
