Sodium aurothiomalate (also known as gold sodium thiomalate) is a gold compound that is used for its immunosuppressive anti-rheumatic effects. It was indicated in the treatment of selected cases of active rheumatoid arthritis—both adult and juvenile type. The greatest benefit occurs in the early active stage. In late stages of the illness when cartilage and bone damage have occurred, gold can only check the progression of rheumatoid arthritis and prevent further structural damage to joints. It cannot repair damage caused by previously active disease. Gold Sodium Thiomalate should be used only as one part of a complete program of therapy; alone it is not a complete treatment. The mode of action is unknown, but was found, that aurothiomalate is able to inhibit Microsomal prostaglandin E synthase-1 (mPGES-1 expression. mPGES-1 is a terminal enzyme in the production of prostaglandin E2 (PGE2) and its expression is upregulated during inflammation. mPGES-1 is considered as a potential drug target for the treatment of arthritis to reduce adverse effects related to the current non-steroidal anti-inflammatory drugs (NSAIDs).

Ponceau xylidine is a component of the Masson's trichrome stain as a red counterstain.

Erucamide is a fatty acid amide, which is similar to the classical endocannabinoid analog oleoylethanolamide. It was discovered in mice, that erucamide may regulate the central nervous system and may have the potential to antagonize depression and anxiety and these effects of the compound may be related to the regulation of the hypothalamus-pituitary-adrenal axis (HPA).
