These are organic compounds containing a sequence of between three and ten alpha-amino acids joined by peptide bonds. Kororamide is found in Lyngbya majuscula. Kororamide was first documented in 2000 (PMID: 10691729). Based on a literature review very few articles have been published on 2-[(4S,10S,13S,23S,26S,29S)-23-[(2S)-butan-2-yl]-2,11,14,21,24,27-hexahydroxy-13-(hydroxymethyl)-29-[(4-hydroxyphenyl)methyl]-16,26-bis(2-methylpropyl)-5-oxo-18,31-dithia-3,6,12,15,22,25,28,33,34-nonaazatetracyclo[28.2.1.1¹⁷,²⁰.0⁶,¹⁰]Tetratriaconta-1(32),2,11,14,17(34),21,24,27,30(33)-nonaen-4-yl]ethanimidic acid.
