Y1085>, SDS of cas: 2873-36-1, the main research area is diketopiperazine isolation structure antibacterial activity Bionectria.
Two new diketopiperazines, 1 new polyprenol, together with 19 known compounds were obtained from the EtOAc extract of Bionectria sp. Y1085, an endophytic fungus isolated from the plant Huperzia serrata. Their structures were elucidated by extensive NMR and MS anal. Bionectin D (I) is a rare diketopiperazine with a single methylthio substitution at the α-carbon of cyclized amino acid residue. The antibacterial activity of compounds was assayed against Escherichia coli, Staphylococcus aureus, and Salmonella typhimurium ATCC 6539, and some metabolites exhibited evident antibacterial activity.
Journal of Antibiotics published new progress about Antibacterial agents. 2873-36-1 belongs to class pyrazines, and the molecular formula is C11H18N2O2, SDS of cas: 2873-36-1.
