Description

colibactin: a hybrid peptide-polyketide secreted by E coli [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

colibactin : A member of the class of 1,3-thiazoles that comprises of two units of 2-[(2-{6-[(2S)-2-methyl-3,4-dihydro-2H-pyrrol-5-yl]-5-oxo-4-azaspiro[2.4]hept-6-en-7-yl}acetamido)methyl]-1,3-thiazole-4-carboxylic acid linked together via the formal condensation of the carboxy groups. It is a secondary metabolite produced by certain strains of bacteria found in the human gut such as Escherichia coli. It has the ability to bind covalently to DNA and is strongly associated with colorectal cancer.

Research Excerpts

Overview

Colibactin is a genotoxic natural product produced by select commensal bacteria in the human gut microbiota. It is a virulence factor and a putative pro-carcinogenic compound. Colibac is long suspected of playing an etiological role in colorectal cancer.

Roles (4)

RoleDescription
alkylating agentHighly reactive chemical that introduces alkyl radicals into biologically active molecules and thereby prevents their proper functioning. It could be used as an antineoplastic agent, but it might be very toxic, with carcinogenic, mutagenic, teratogenic, and immunosuppressant actions. It could also be used as a component of poison gases.
Escherichia coli metaboliteAny bacterial metabolite produced during a metabolic reaction in Escherichia coli.
genotoxinA role played by a chemical compound to induce direct or indirect DNA damage. Such damage can potentially lead to the formation of a malignant tumour, but DNA damage does not lead inevitably to the creation of cancerous cells.
carcinogenic agentA role played by a chemical compound which is known to induce a process of carcinogenesis by corrupting normal cellular pathways, leading to the acquistion of tumoral capabilities.

Drug Classes (5)

ClassDescription
1,3-thiazoles
polyketideNatural and synthetic compounds containing alternating carbonyl and methylene groups ('beta-polyketones'), biogenetically derived from repeated condensation of acetyl coenzyme A (via malonyl coenzyme A), and usually the compounds derived from them by further condensations, etc. Considered by many to be synonymous with the less frequently used terms acetogenins and ketides.
pyrrolineAny organic heteromonocyclic compound with a structure based on a dihydropyrrole.
secondary carboxamideA carboxamide resulting from the formal condensation of a carboxylic acid with a primary amine; formula RC(=O)NHR(1).
azaspiro compoundAn azaspiro compound is a spiro compound in which at least one of the cyclic components is a nitrogen heterocyle.
