SIRT1-IN-1 is a selective SIRT1 inhibitor with an IC50 of 0.205 μM. SIRT1-IN-1 inhibits SIRT2 with an IC50 of 11.5 μM[1]. SIRT1-IN-1, a indole, is a cytomegalovirus (CMV) inhibitors and has antiviral activity[2].
SIRT1-IN-1 (compound 2) has little effect on SIRT3 (IC50>100 μM) and HDAC (IC50>100 μM)[1].
