Investigation of the fungus Phoma herbarum PSU-H256 isolated from a leaf of Hevea brasiliensis resulted in the isolation of eight terezine derivatives (E-L) together with four known compounds. Their structures were established by analysis of spectroscopic evidence. For terezines E and H, their structures were confirmed by single-crystal X-ray diffraction crystallography. In addition, the absolute configuration at C-7 in terezine E was established by Mosher's method. Terezines K and L were tested for antibacterial, antimalarial, antimycobacterial and cytotoxic activities, but were inactive.
对从巴西橡胶树叶中分离出的草本茎点霉PSU - H256进行研究,结果分离出了8种特瑞嗪衍生物(E - L)以及4种已知化合物。通过光谱证据分析确定了它们的结构。对于特瑞嗪E和H,通过单晶X射线衍射晶体学确定了它们的结构。此外,通过莫舍尔方法确定了特瑞嗪E中C - 7位的绝对构型。对特瑞嗪K和L进行了抗菌、抗疟、抗分枝杆菌和细胞毒性活性测试,但它们没有活性。
