The unusual cyclobutanol containing dipeptide (1,2)-1-Hydroxy-2-[(S)-valylamino]cyclobutane-1-acetic acid (1), produced by an as yet unidentified Streptomyces species X-1092, has been synthesised a short stereoselective route. Acid hydrolysis of (1) gave (1,2)-1-hydroxy-2-aminocyclobutane-1-acetic acid (2) which in direct comparison tests to (1) gave enhanced antibacterial activity against the gram-positive
由一种尚未鉴定的链霉菌种X-1092生产的不寻常的含二肽(1,2 )-1-羟基-2-[((S)-戊基氨基]环丁烷-1-乙酸)的环丁醇已被合成为短的立体选择性途径。(1)的酸水解得到(1,2 )-1-羟基-2-氨基环丁烷-1-乙酸(2),在与(1)的直接比较试验中,其增强了对革兰氏阳性生物ATCC 6633的抗菌活性。提出了一种有趣的机制,其中(2)充当基于吡咯醛的关键酶胱硫醚-γ-合成酶的“自杀底物”,从而产生抗菌作用;仿生研究支持该建议。
