Common NameFumiquinazoline F
DescriptionFumiquinazoline F is a peptidyl alkaloid belonging to the chemical class of nonribosomal peptides. Its chemical structure features an indole side chain that is intricately linked to an alaninyl or aminoisobutyryl unit through nonribosomal peptide synthetase (NRPS) enzymes, which facilitate its biosynthesis via a series of condensation reactions (PMID:21591693 ). This compound exhibits notable bioactivity, demonstrating efficacy against hormone-dependent epithelial MCF-7 and hormone-resistant triple-negative MDA-MB-231 breast cancer cells, with IC50 values of 48 μM and 54.1 μM, respectively (PMID:40806710 ). In MDA-MB-231 cells treated with fumiquinazoline F, fluctuations in proteins associated with epithelial-mesenchymal transition (EMT), such as E-cadherin and vimentin, lead to reduced cell migration and adhesion (PMID:40806710 ). The biosynthetic pathway of fumiquinazoline F involves the enzyme FqzB, a flavin monooxygenase (FMO) that catalyzes its epoxidation and exhibits broad substrate specificity, accepting various substrates including tryprostatins (PMID:33332106 ). This pathway also intersects with the fumitremorgin biosynthetic route, contributing to the formation of spirotryprostatin A (PMID:33332106 ).
