Eupenicillium sp.E-UN41产活性物质的分离与结构分析
在筛选微生物来源代谢产物的过程中,分离得到一株正青霉Eupenicillium sp.E-UN41,发酵液经离子交换树脂和葡聚糖凝胶等方法分离得到化合物UN41A.通过核磁共振波谱和X-单晶衍射进行该化合物的分子构型和晶体结构分析,确定其为4-氨甲酰基-1-β-D-呋喃核糖-5-羟基咪唑,与咪唑立宾同质.晶体属斜方晶系,空间群P212121,晶胞参数a=7.4897(7),b=11.3801 (15),c=14.0090(13)(A),V=1194.0(2) (A)3,Z=4,Dc=1.553g/m3,F(000) =592.晶体结构分析表明,分子中存在咪唑环共平面.
