beauvericin beauvericin beauvericin is a depsipeptide with antibiotic and insecticidal effects belonging to the enniatin family. it was isolated from the fungus beauveria bassiana, but is also produced by several other fungi, including several fusarium species; it may therefore occur in grain (such as corn, wheat and barley) contaminated with these fungi. beauvericin is active against gram-positive bacteria and mycobacteria, and is also capable of inducing programmed cell death in mammals. beauvericin names iupac name (3s,6r,9s,12r,15s,18r)-3,9,15-tribenzyl-6,12,18-triisopropyl-4,10,16-trimethyl-1,7,13-trioxa-4,10,16-triazacyclooctadecane-2,5,8,11,14,17-hexone identifiers cas number 26048-05-5 y 3d model (jsmol) interactive image chebi chebi:3000 y chembl chembl373872 n chemspider 2277520 y kegg c11590 n pubchem cid 3007984 unii 26s048ls2r y comptox dashboard (epa) dtxsid00891834 inchi inchi=1s/c45h57n3o9/c1-28(2)37-40(49)46(7)35(26-32-21-15-11-16-22-32)44(53)56-39(30(5)6)42(51)48(9)36(27-33-23-17-12-18-24-33)45(54)57-38(29(3)4)41(50)47(8)34(43(52)55-37)25-31-19-13-10-14-20-31/h10-24,28-30,34-39h,25-27h2,1-9h3/t34-,35-,36-,37+,38+,39+/m0/s1 ykey: gyscaqfhasjxrs-ffcojmsvsa-n yinchi=1/c45h57n3o9/c1-28(2)37-40(49)46(7)35(26-32-21-15-11-16-22-32)44(53)56-39(30(5)6)42(51)48(9)36(27-33-23-17-12-18-24-33)45(54)57-38(29(3)4)41(50)47(8)34(43(52)55-37)25-31-19-13-10-14-20-31/h10-24,28-30,34-39h,25-27h2,1-9h3/t34-,35-,36-,37+,38+,39+/m0/s1key: gyscaqfhasjxrs-ffcojmsvbb smiles o=c1n(c)(c(=o)o(c(=o)n((c(=o)o(c(=o)n((c(=o)o1c(c)c)cc2ccccc2)c)c(c)c)cc3ccccc3)c)c(c)c)cc4ccccc4 properties chemical formula c45h57n3o9 molar mass 783.963 g·mol−1 except where otherwise noted, data are given for materials in their standard state (at 25 °c , 100 kpa). n verify (what is yn ?) infobox references chemically, beauvericin is a cyclic hexadepsipeptide with alternating n-methyl-phenylalanyl and d-hydroxy-iso-valeryl residues. its ion-complexing capability allows beauvericin to transport alkaline earth metal and alkali metal ions across cell membranes. beauvericin has in vitro fungicidal effects on candida parapsilosis when used in combination with the antifungal drug ketoconazole at dosages of 0.1 μg/ml. increased survivability rates and low cytotoxicity were also observed in mouse models.
