Equisetin 是从陆生真菌 Fusarium equiseti NRRL 5537 中分离出的 N-甲基丝氨酸衍生的酰基特拉姆酸，它作为一种含有四联体的天然产物，具有抗生素和细胞毒活性，可以抑制革兰氏阳性菌的生长和 HIV-1 整合酶活性，但对革兰氏阴性菌没有活性。Equisetin 是一种群体感应抑制剂 (QSI)，可减弱铜绿假单胞菌中 QS 调节的毒性表型而不影响细菌的生长，是研究铜绿假单胞菌感染的主要化合物。
| 生物活性 |
Equisetin is an N-methylserine-derived acyl tetramic acid isolated from a terrestrial fungus Fusarium equiseti NRRL 5537. Equisetin is a tetramate-containing natural product with antibiotic and cytotoxic activity. Equisetin inhibits the growth of Gram-positive bacteria and HIV-1 integrase activity but shows no activity against Gram-negative bacteria. Equisetin is a Quorum-sensing inhibitor (QSI) that attenuates QS-regulated virulence phenotypes in P. aeruginosa without affecting the growth of bacterias, serves as a leading compound for the treatment of P. aeruginosa infections. |
