Purpurides B and C (1 and 2, resp.), two new sesquiterpene alcohol esters generated from a drimane-type sesquiterpenoid lactone and an amino acid, together with two known analogs, berkedrimane B (3) and purpuride (4), were isolated from the aciduric fungus Penicillium purpurogenum JS03-21. Their structures were elucidated by spectroscopic analysis, X-ray single-crystal diffraction, and application
分离出紫癜B和C(分别为1和2),两种由drimane型倍半萜内酯和一种氨基酸生成的新的倍半萜烯醇酯,以及两个已知的类似物,伯克瑞丹烷B(3)和紫杉醇(4)。来自酸性尿真菌紫青霉JS03-21。通过光谱分析,X射线单晶衍射和Marfey方法的应用阐明了它们的结构。化合物1-4对白色念珠菌显示适度的抗真菌活性,MIC值为1.2-3.3μM。化合物1和2对产气肠杆菌和铜绿假单胞菌显示中等的抗菌活性,MIC值在1.2-2.6μM的范围内。
