A peptide comprising a unit of formula (I) and having a molecular weight of less than 2000 wherein each X is independently an organic group, e.g. a C1-6 alkyl or C1-6 alkenyl group, preferably —CH2—CH═CH2, or the two X groups taken together can form a covalent or non-covalent link between the two O groups, preferably a C1-10 saturated or unsaturated carbon chain optionally interrupted by one or more heteroatoms selected from O, S, N, P, or Si, especially a C3-10 carbon chain or one X represents an azido group and the other an C2-6-alkynyl group; both Z's are the same and are O or S; each Y is independently C, CH, CH2, N or NH; R1 is H or C1-6 alkyl; R2 is H or C1-6 alkyl; R5 is a C1-6 alkyl group, preferably isopropyl; or a salt, ester or prodrug thereof.
一种肽,包括式(I)的单元,分子量小于2000,其中每个X独立地是一个有机基团,例如C1-6烷基或C1-6烯基基团,首选为—CH2—CH═CH2,或者两个X基团一起形成两个O基团之间的共价或非共价连接,首选为C1-10饱和或不饱和碳链,可以由O、S、N、P或Si中选择的一个或多个杂原子中断,特别是C3-10碳链,或一个X代表一个叠氮基团,另一个代表一个C2-6-炔基基团;两个Z相同,都是O或S;每个Y独立地是C、CH、CH2、N或NH;R1是H或C1-6烷基;R2是H或C1-6烷基;R5是C1-6烷基基团,首选异丙基;或其盐、酯或前药。
