PG 34 is a weak O-GlcNAc transferase (OGT) inhibitor (IC50=68 μM), and a close structural analog of OSMI-1 .
PG34 (0.5-50 µM; 24 h) shows no detectable inhibition of OGT in CHO cells, displays no effect on apoptotic signaling, and shows a moderate effect on cell viability only at the highest concentration[1].
