Shikimic acid Chemical Properties,Usage,Production

Description

Shikimic acid (3,4,5-trihydroxy-1-cyclohexene-1-carboxylic acid) is a natural organic compound. Plant and microbial sources are the only sources of this compound. The isolation of shikimic acid from the fruit of Illicium religiosum was primarily reported by Ekmann in 1885. The name shikimic acid was derived from the oriental plant shikimi-no-ki in Japanese. It is now available in more quantities through the extraction from the fruit Illicium verum (Chinese star anise). This compound is generally utilized as a starting material for the industrial synthesis of the antiviral oseltamivir, a drug against the H1N1 influenza virus. It is also an essential intermediate in the biosynthesis of lignin, aromatic amino acids (phenylalanine, tyrosine, and tryptophan), and most alkaloids of plants and microorganisms[1]. The neuraminidase inhibitors oseltamivir or Tamiflu derived from the shikimic acid pathway are potent influenza viral neuraminidase inhibitors against most influenza strains ( influenza A and B infections). The mode of application is by mouth, either in the form of a pill or liquid.

Chemical Properties

White Solid

Uses

Shikimic acid has been used as a standard for the quantification of shikimate in apical parts of roots. It has also been used as a substrate in shikimate kinase assay.

Uses

Naturally occurring (-)-form is a major biosynthetic precursor of phenylalanine, tyrosine, and tryptophan and hence of the majority of plant alkaloids. It is also involved in the biosynthesis of lignin, flavonpids and other important aromatic compounds.

Definition

ChEBI: A cyclohexenecarboxylic acid that is cyclohex-1-ene-1-carboxylic acid substituted by hydroxy groups at positions 3, 4 and 5 (the 3R,4S,5R stereoisomer). It is an intermediate metabolite in plants and micro rganisms.

Biochem/physiol Actions

Shikimic acid is observed to be carcinogenic in rat models, when administered. It serves as a precursor for the biosynthesis of aromatic amino acids, alkaloids and other aromatic metabolites in microorganisms. Shikimic acid is known to inhibit adenosine diphosphate (ADP) induced platelet aggregation and blood coagulation in rabbits.
