Use of Dihydrocoumarin

Dihydrocoumarin is a compound found in Melilotus officinalis. Dihydrocoumarin is a yeast Sir2p inhibitor. Dihydrocoumarin also inhibits human SIRT1 and SIRT2 with IC50s of 208 μM and 295 μM, respectively[1].

Description	Dihydrocoumarin is a compound found in Melilotus officinalis. Dihydrocoumarin is a yeast Sir2p inhibitor. Dihydrocoumarin also inhibits human SIRT1 and SIRT2 with IC50s of 208 μM and 295 μM, respectively[1].

In Vitro	Dihydrocoumarin induces a concentration-dependent inhibition of SIRT1 (IC50 of 208 μM) in an in vitro enzymatic assay. A decrease in SIRT1 deacetylase activity is observed even at micromolar doses (85±5.8 and 73±13.7% activity at 1.6 μM and 8 μM, respectively). The microtubule SIRT2 deacetylase is also inhibited with a similar dose dependency (IC50 of 295 μM)[1]. Dihydrocoumarin (1-5 mM) increases cytotoxicity in the TK6 cell line in a dose-dependent manner following a 24-h exposure. Dihydrocoumarin (1-5 mM) increases apoptosis in a dose-dependent manner in the TK6 cell line at the 6-h time point. A 5-mM dose of Dihydrocoumarin increases apoptosis at the 6-h time point in the TK6 cell line[1]. Dihydrocoumarin (1-5 mM) increases p53 lysine 373 and 382 acetylation in a dose-dependent manner in the TK6 cell line following a 24-h exposure period[1].
