The discovery of pamaquine, developed by replacing one of the methyl groups of methylene blue by a dialkylaminoalkyl chain, was a landmark in the design of drugs for malaria. It is closely related to primaquine. The administration of pamaquine during the incubation period delayed but did not prevent primary attacks of a New Guinea strain of Plasmodium vivax malaria. Hemolytic anemia after administration of the antimalarial drug pamaquine was reported in patients with Glucose-6-phosphate dehydrogenase (G6PD) deficiency. Pamaquine itself could not be used clinically due to high toxicity.

Hexylresorcinol is an organic compound with local anaesthetic, antiseptic and anthelmintic properties. It is available for use topically on small skin infections, or as an ingredient in throat lozenges. Hexylresorcinol may be used as a cosmetic biocide. Hexylresorcinol was introduced by Leonard as a urinary antiseptic with great possibilities. Used in alkaline solution it promised success in experiments in vitro. Boots Hexylresorcinol 2.4mg Throat Lozenges, marketed in UK, are used to relieve sore throat pain. Hexylresorcinol has being shown to be useful for the topical treatment of hyperpigmentation.

Scopolamine Aminoxide Hydrobromide is one of Scopolamine metabolites, with remarkable Acetylcholinesterase inhibitory activity.
