Four new polyketides named trichodermatides A-D (1-4), along with five known analogues (5-9), were isolated from the fungus Trichoderma sp. XM-3. Their structures were elucidated on the basis of HRESIMS and NMR analyses, and their absolute configurations were determined by ECD comparison, H and C NMR calculation, DP4+ analysis, modified Mosher's method, and X-ray crystallography. Trichodermaketone D (9) showed mild antibacterial activity against Pseudomonas aeruginosa.
从真菌 Trichoderma sp. XM-3 中分离得到了四个新的聚酮化合物，分别命名为 trichodermatides A-D（1-4），以及五个已知类似物（5-9）。基于高分辨质谱（HRESIMS）和核磁共振（NMR）分析，确定了它们的结构，并通过 ECD 比较、1H 和 13C NMR 计算、DP4+分析、改进的 Mosher 法和 X 射线晶体学确定了它们的绝对构型。trichodermaketone D（9）对铜绿假单胞菌表现出轻微的抗菌活性。
