Dimecrotic acid is a choleretic agent with spasmolytic properties. It is obtained by reaction of resorcinol with acetoacetate to give 4-methyl-7-hydroxycoumarin. It is indicated for the treatment of hepato-digestive insufficiency and its manifestations. It shouldn’t be used in case of blockage of bile ducts, severe liver failure and severe renal impairment. Diarrhea may be associated with high doses of dimecrotic acid.

Camphoric acid is a product of oxidation of camphor, naturally occurring in rosemary. In the early twentieth century, camphoric acid was used in the night-sweats of phthisis and was also employed in solution as a local antiseptic to the nose, throat, and bladder. Camphoric acid was found to induce the expression of glutamate receptors NMDAR1, GluR3/4, and mGluR8.

Agaricic acid is a resin acid that obtained by extraction with alcohol from obtained from various fungus plants (mushroom) such as Polyporus officinalis (a wood-decay fungus). Since the late 19th century it was used as an antipyretic and antiperspirant, and was official in the German Pharmacopoeia under the name of Agaricinum. Agaricic acid is a sesquihydrate, odorless, almost tasteless, crystalline powder, little soluble in cold water. It is irritant to the gastro-intestinal tract. Experiments on the synthesis of agaricic acid as well as studies of its pharmacological properties are known since 1960s. It was found that Agaricic acid was highly inhibitory (50 to 100%) to malic and alpha-glycerophosphate dehydrogenases of the insect trypanosomatid, Crithidia fasciculata. Agaricic acid is a mycotoxin and is considered under regulations and guidelines established in European Union to protect the consumer from the harmful effects mycotoxins in food. Agaricic acid is among the newest agents to function in the treatment of wrinkles: it inhibits the cross-linking process which leads to dermal proteins denaturation.

Glucuronic acid (α-D-GLUCURONIC ACID) is a carboxylic acid that has the structure of a glucose molecule that has had its sixth carbon atom (of six total) oxidized. The salts of glucuronic acid are known as glucuronates. Glucuronic acid is highly soluble in water. In humans, glucuronic acid is often linked to toxic or poisonous substances to allow for subsequent elimination, and to hormones to allow for easier transport. These linkages involve O-glycosidic bonds. The process is known as glucuronidation, and the resulting substances are known as glucuronides (or glucuronosides). Glucuronidation uses UDP-glucuronic acid (glucuronic acid linked via a glycosidic bond to uridine diphosphate) as an intermediate. UDP-glucuronic acid is formed in the liver of all animals. α-D-GLUCURONIC ACID is used as pharmaceutical intermediate and in chemical research.
