DescriptionReblastatin belongs to the class of organic compounds known as macrolactams. These are cyclic amides of amino carboxylic acids, having a 1-azacycloalkan-2-one structure, or analogues having unsaturation or heteroatoms replacing one or more carbon atoms of the ring. They are nitrogen analogues (the a nitrogen atom replacing the o atom of the cyclic carboxylic acid group ) of the naturally occurring macrolides. {[(4e,8s,9s,10e,12s,13r,14s,16r)-3,13,20-trihydroxy-8,14,19-trimethoxy-4,10,12,16-tetramethyl-2-azabicyclo[16.3.1]docosa-1(21),2,4,10,18(22),19-hexaen-9-yl]oxy}methanimidic acid is found in Streptomyces hygroscopicus. It was first documented in 2018 (PMID: 29265716). Based on a literature review a significant number of articles have been published on reblastatin (PMID: 30893410) (PMID: 32663707) (PMID: 32395369) (PMID: 31089638).
