Hirsutenone is an active botanical diarylheptanoid present in Alnus species and exhibits many biological activities, including anti-inflammatory, anti-tumor promoting and anti-atopic dermatitis effects. Hirsutenone attenuates adipogenesis by binding directly to PI3K and ERK1 in a non-ATP competitive manner. Hirsutenone can be used for the study of obesity[1].

Hirsutenone (0-100 μM; 48 hours) inhibits adipogenesis in 3T3-L1 preadipocytes and exhibits non-toxicity at 20-100 μM[1].Hirsutenone (0-100 μM; 48 hours) attenuates MDI-induced lipid accumulation in 3T3-L1 preadipocytes in a dose-dependent manner. In particular, HST at 40 and 80 μM significantly reduces MDI-induced adipogenesis in 3T3-L1 preadipocytes[1].Hirsutenone (0-100 μM; 48 hours) reduces the protein expression levels of PPARg, C/EBPa, and FAS in a dose-dependent manner in 3T3-L1 preadipocytes[1].Hirsutenone (80 μM; 20-24 hours) suppresses the cell cycle entry to S and G2/M phases occurrs at 20 hours when compares with at 20 hours. At 24 h, more cells are arrested in G1 phase (53% of total cells) when compares with the MDI-induced group which contains the majority of cells (56% of total cells) in G2/M phase[1].
