SHIN1 is an inhibitor of human serine hydroxymethyltransferse 1(SHMT1) with IC50 of 5 nM and human serine hydroxymethyltransferse 2 (SHMT2) with an IC50 of 13 nM.

O-Acetylserine (OASS) is an acylated amino acid derivative. It is an intermediate in the biosynthesis of the common amino acid cysteine in bacteria and plants. Its presence in humans arises from either microbial metabolism in the gut or through consumption of foods containing OASS.

Dynamin-related protein 1 (Drp1) inhibitor, inhibits Drp1 GTPase activity. Displays no effect on dynamin 1 or other mitochondrial dynamics-related proteins. Inhibits mitochondrial fission, dysfunction and reactive oxygen species (ROS) production in vitro. Reduces programmed cell death and improves cell viability by protecting mitochondrial integrity. Reduces mitochondrial fragmentation and mitochondrial ROS production in mouse model of Parkinson's disease. Cell permeable.
