Altenusin is a natural nonsteroidal fungal metabolite, as a novel selective agonist of FXR with an EC50 value of 3.2 ± 0.2 μM.

Treatment of primary mouse hepatocytes with altenusin inhibited oleic acid–induced steatosis in vitro [1].

Administration of 2076A protected mice from high-fat diet (HFD)-induced obesity by reducing the body weight and fat mass by 22.9% and 50.0%, respectively. Administration of 2076A also decreased the blood glucose level from 178.3 ± 12.4 mg/dl to 116.2 ± 4.1 mg/dl and the serum insulin level from 1.4 ± 0.6 ng/dl to 0.4 ± 0.1 ng/dl[1].
