Alternariol 9-O-methyl ether dimethyl sulfoxide monosolvate
THE TITLE COMPOUND (SYSTEMATIC NAME 3,7-dihy-droxy-9-meth-oxy-1-methyl-6H-benzo[c]chromen-6-one dimethyl sulfoxide monosolvate), C15H12O5·C2H6OS, was isolated from an unidentified endophytic fungus (belonging to class Ascomycetes) of Taxus sp. In the crystal, both the alternariol 9-O-methyl ether (AME) and the dimethyl sulfoxide (DMSO) mol-ecules exhibit crystallographic mirror symmetry. One of...
متن کاملAlternariol 9-O-methyl ether
The title compound (AME; systematic name: 3,7-dihy-droxy-9-meth-oxy-1-methyl-6H-benzo[c]chromen-6-one), C(15)H(12)O(5), was isolated from an endophytic fungi Alternaria sp., from Catharanthus roseus (common name: Madagascar periwinkle). There is an intramolecular O-H⋯O hydrogen bond in the essentially planar mol-ecule (r.m.s. deviation 0.02 Å). In the crystal, the molecule forms an O-H⋯O hydrog...
متن کاملIdentification of a Polyketide Synthase Required for Alternariol (AOH) and Alternariol-9-Methyl Ether (AME) Formation in Alternaria alternata
Alternaria alternata produces more than 60 secondary metabolites, among which alternariol (AOH) and alternariol-9-methyl ether (AME) are important mycotoxins. Whereas the toxicology of these two polyketide-based compounds has been studied, nothing is known about the genetics of their biosynthesis. One of the postulated core enzymes in the biosynthesis of AOH and AME is polyketide synthase (PKS)...
متن کاملcis-Dichloridotetrakis(dimethyl sulfoxide-κO)chromium(III) chloride dimethyl sulfoxide monosolvate
The structure of the title compound, [CrCl2(C2H6OS)4]Cl·C2H6OS, consists of a Cr(III) ion coordinated by four O atoms of dimethyl sulfoxide (DMSO) ligands and two chloride ions in cis positions, forming a distorted CrCl2O4 octa-hedron. An isolated Cl(-) counter-anion and a positionally disordered DMSO mol-ecule [occupancy ratio 0.654 (4):0.346 (4)] are also present. In the structure, the comple...
متن کامل2-Amino-1-methyl-1H-imidazol-4(5H)-one dimethyl sulfoxide monosolvate
In the title compound, C(4)H(7)N(3)O·C(2)H(6)OS, creatinine [2-amino-1-methyl-1H-imidazol-4(5H)one] exists in the amine form. The ring is planar (r.m.s. deviation for all non-H atoms = 0.017 Å). In the crystal, two creatinine mol-ecules form centrosymmetric hydrogen-bonded dimers linked by pairs of N-H⋯N hydrogen bonds. In addition, creatinine is linked to a dimethyl sulfoxide mol-ecule by an N...
