2,6,4'-Trihydroxy-4-methoxybenzophenone shows weak inhibitory activity of testosterone 5alpha-reductase, it also shows significant inhibition of pancreatic lipase activity.

Diphenylterazine is a bioluminescence compound.Diphenylterazine alone yields very little background with excellent signal-to-background ratios. Furthermore, Diphenylterazine elicits minimal cell toxicity at millimolar concentrations. Diphenylterazine injections into untransfected BALB/c mice do not yield any background emission.
