N-methyl-D-leucine, L-proline (or trans-4-methyl L-proline), D-isoleucine (or D-valine), (3R)-piperazic acid [or (3R,5S)-5-chloropiperazic acid, or (3R)-4,5 (or 5,6)-dehydropiperazic acid], and (3S,5S)-5-hydroxypiperazic acid. The name piperazic acid is assigned to hexahydropyridazine-3-carboxylic acid.
莫纳霉素是一种结晶的抗菌制剂,从牙买加链霉菌的培养物中分离出来,由十五种环六肽肽的混合物组成,其中六种含氯。每个分子种类由一个α-羟基酸残基(L -2-羟基-3-甲基丁酸或L -2-羟基-3-甲基戊酸)和五个α-氨基或亚氨基酸残基组成。后者由N-甲基-D-亮氨酸,L-脯氨酸(或反式-4-甲基L-脯氨酸),D-异亮氨酸(或D-缬氨酸),(3 R)-哌嗪酸[或(3 R, 5 S)-5-氯哌嗪酸或(3R)-4,5(或5,6)-脱氢哌嗪酸]和(3 S,5 S)-5-羟基哌嗪酸。名称哌嗪酸被指定为六氢哒嗪-3-羧酸。
