SIRT7 inhibitor 97491 是SIRT7的有效抑制剂，IC50为 325 nM。SIRT7 inhibitor 97491以剂量依赖性的方式降低 SIRT7 去乙酰化酶活性。它通过在 K373/382 处进行乙酰化来提高 p53 的稳定性，从而防止肿瘤进展。它通过 Caspase 途径促进凋亡。

SIRT7 inhibitor 97491 is an HDAC inhibitor with high specificity for SIRT7 (IC50 = 325 nM). SIRT7 inhibitor 97491 promotes apoptosis through caspase pathway.

SIRT7 inhibitor 97491 decreased SIRT7 activity in a dose-dependent manner. SIRT7 inhibitor 97491 induced expression of p53 and its acetylation by inhibited SIRT7. SIRT7 inhibitor 97491 (1-10 μM) reduces cell growth in MES-SA cells, without causing cytotoxicity in HEK293 cells[1].

In xenograft mice, SIRT7 inhibitor 97491 (2 mg/kg; i.p) inhibited tumor growth. SIRT7 inhibitor 97491 upregulated apoptotic effects through the caspase related proteins and inhibited cancer growth in vivo[1].
