PDI-IN-P1 is an inhibitor of protein disulfide isomerase.

SZL P1-41, a skp2 inhibitor, can prevent assembly of Skp2-Skp1 complexes. It selectively suppresses Skp2 SCF E3 ligase activity but exhibits no effect on the activity of other SCF complexes. It also inhibits Skp2-mediated p27 and Akt ubiquitination in vivo and in vitro. It suppresses the survival of Y cells and Y stem cells by triggering cell senescence and inhibiting glycolysis. It exhibits antitumor effects in multiple animal models and Y cell lines.

The phosphatidylinositol (PtdIns) phosphates represent a small percentage of total membrane phospholipids. However, they play a critical role in the generation and transmission of cellular signals. PtdIns-(4)-P1 (1,2-dioctanoyl) is a synthetic analog of natural phosphatidylinositol (PtdIns) featuring C8:0 fatty acids at the sn-1 and sn-2 positions. The compound contains the same inositol and diacylglycerol (DAG) stereochemistry as the natural compound. PtdIns-(4)-P1 can be phosphorylated to di- (PtdIns-P2; PIP2) and triphosphates (PtdIns-P3; PIP3). Hydrolysis of PtdIns-(4,5)-P2 by phosphoinositide (PI)-specific phospholipase C generates inositol triphosphate (IP3) and DAG which are key second messengers in an intricate biochemical signal transduction cascade.
