PU 02

PU02, a derivative of 6-MP (HY-13677), is a negative allosteric modulator (NAM) of 5-HT3 receptor, with IC50 values of 0.36 and 0.73 μM in HEK293 cells transfected with human 5-HT3A and 5-HT3AB receptors respectively[1][2].

PU02 (NMMP) (0-200 μM) leads to a steady decrease in cell viability of HepG2 cells (IC50=48.585 μM). PU02 (NMMP) shows less toxicity on L02 cells than did 6-MP after 48 h of treatment[2]. PU02 (NMMP) at 6.25 or 25 μM exhibits inhibitory effects on the viability of the tested cell lines, including SMMC-7721, MDA-MB-231, RKO and HCT-8 cells[2]. PU02 (NMMP) induces cell cycle arrest at the G2/M phase. PU02 (NMMP) downregulats the expression of cyclin B1/D1 and CDK4 in a time-dependent manner in HepG2 cells,but the expression of cyclin E is not affected[2]. PU02 (NMMP)-treated cells exhibits a significant increase in caspase-3 cleavage, suggesting enhanced apoptotic activity[2]. Apoptosis Analysis[2] Cell Line: HepG2 cells. Concentration: 6.26, 12.5, 25, 50 μM. Incubation Time: 6, 12, 24, 36 h. Result: Induced mitochondria-dependent apoptosis.
