SUV39H2/KMT1B Inhibitor

OTS193320, a imidazo[1,2-a]pyridine compound, is a SUV39H2 methyltransferase activity inhibitor. OTS193320 decreases global histone H3 lysine 9 tri-methylation levels in breast cancer cells and triggers apoptotic cell death. Combination of OTS193320 with Doxorubicin (HY-15142A) results in reduction of γ-H2AX levels as well as cancer cell viability compared to a single agent OTS193320 or DOX.

Go 6983 GMP is Go 6983 (HY-13689) produced by using GMP guidelines. GMP small molecules works appropriately as an auxiliary reagent for cell therapy manufacture. Go 6983 is a dual inhibitor targeting Suv39h1/2 (KMT1A/KMT1B) and PKC, as well as a transcriptional activator capable of inducing DNA hypomethylation. Go 6983 stimulates the transcription of Prdm14 by reducing Suv39h1/2 protein levels, decreasing histone modifications in the Prdm14 promoter region, and increasing the recruitment of RNA polymerase II. Go 6983 induces genome-wide DNA hypomethylation by inhibiting de novo methyltransferase expression and increasing Tet1/Tet2 levels, thereby promoting self-renewal and pluripotency maintenance of stem cells. Meanwhile, Go 6983 can block PKC-mediated signaling pathways to reduce the expression of EMT-related genes and eliminate the upregulation of antioxidant genes downstream of NRF2. Go 6983 is mainly used in mechanism studies related to myocardial ischemia/reperfusion injury.
