4-Hydroxy-4-(3-hydroxy-1-butenyl)-3,5,5-trimethyl-2-cyclohexen-1-one, (4S,3R)-(E)-(±)- (Blumenol A) is a major secondary metabolite initially isolated from the leaves of Annona glabra L. (Annonaceae), commonly known as pond apple, which is a tropical tree distributed mainly in the Americas and in Southeast Asia, and used in traditional medicine as an insecticide and a parasiticide. Blumenol A was reported to display inhibitory activity against a panel of human solid tumor cell lines

MK-912 is non-specific alpha-2 adrenergic receptor antagonist, with high affinity for the alpha-2-A, alpha-2B, and alpha-2C variants. Originally developed by Merk & Co, it has been investigated for potential therapeutic properties for the treatment of depression and diabetes. MK-912 is also regularly used as a molecular probe in biomedical studies seeking information about alpha-2 adrenergic receptors.
