7,12-Dimethylbenz[a]anthracene is a highly potent carcinogen that is activated by microsomal enzymes to a diol epoxide metabolite that binds covalently to DNA in mammalian cells, leading ultimately to tumor induction.

[Met5]-Enkephalin, amide is an agonist for δ opioid receptors as well as putative ζ (zeta) opioid receptors.Met-enkephalin circulates in several forms, some of which may be derived from proteins other than proenkephalin A, and plasma levels of both free native, and peptidase-derivable Met-enkephalin are modulated physiologically.

1-((3R,4S)-3-hydroxy-2,2-dimethyl-6-(phenylsulfonyl)chroman-4-yl)pyrrolidin-2-one is an isomer of Rilmakalim, a potassium channel opener (PCO), which can activate ATP-sensitive K+ channels in the heart or other tissues
