| Common Name | (2s,5r,6r)-6-{[(2,6-dimethoxyphenyl)(hydroxy)methylidene]amino}-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo[3.2.0]heptane-2-carboxylic acid |

| Description | Meticillin, also known as staphcillin or metin, belongs to the class of organic compounds known as dipeptides. These are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. Meticillin is a drug which is used to treat infections caused by susceptible gram-positive bacteria, particularly beta-lactamase-producing organisms such as staphylococcus aureus that would otherwise be resistant to most penicillins. Meticillin is an extremely weak basic (essentially neutral) compound (based on its pKa). (2s,5r,6r)-6-{[(2,6-dimethoxyphenyl)(hydroxy)methylidene]amino}-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo[3.2.0]heptane-2-carboxylic acid is found in Diphasiastrum digitatum, Lycopodium deuterodensum, Streptomyces cavourensis and Tanacetum argenteum. (2s,5r,6r)-6-{[(2,6-dimethoxyphenyl)(hydroxy)methylidene]amino}-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo[3.2.0]heptane-2-carboxylic acid was first documented in 2014 (PMID: 24433925). A penicillin that is 6-aminopenicillanic acid in which one of the amino hydrogens is replaced by a 2,6-dimethoxybenzoyl group. |
