AS-85, a potent inhibitor of ASH1L histone methyltransferase (IC50 = 0.6 μM), exhibits anti-leukemic activity by strongly binding to the ASH1L SET domain (Kd = 0.78 μM).

calmodulin antagonist.

Grossamide possesses potential anti-inflammatory effects, it also has potential anti-neuroinflammatory effects against lipopolysaccharide (LPS)-induced inflammatory response in BV2 microglia cells. Cis-Grossamide K exerts a particularly strong anti-melanogenic activity on the cells without high cell toxicity.
