Amphiphilic prodrugs of general formula A-X are disclosed, wherein A is a biologically active agent or may be metabolised to a biologically active agent; and X is selected from the group consisting of R, or up to three R moieties attached to a linker, Y1, Y2 or Y3, wherein R is selected from a group consisting of alkyl, alkenyl, alkynyl, branched alkyl, branched alkenyl, branched alkynyl, substituted alkyl, substituted alkenyl and substituted alkynyl groups and their analogues; Y1 is a linker group which covalently attached to an R group at one site and is attached to A at a further independent site; Y2 is a linker group which is covalently attached to two R groups at two independent sites and is attached to A at a further independent site; and Y3 is a linker group which is covalently attached to three R groups at three independent sites and is attached to A at a further independent site. Self-assembly of the amphiphilic prodrugs into reverse lyotropic phases, particularly hexagonal, cubic and sponge, is disclosed. In preferred embodiments A is dopamine or a 5-fluorouracil prodrug.
本发明公开了一般式A-X的两亲性前药,其中A是生物活性剂或可代谢为生物活性剂;X选自以下组中的一种:R,或连接剂Y1、Y2或Y3上附着的最多三个R基团,其中R选自烷基、烯基、炔基、支链烷基、支链烯基、支链炔基、取代烷基、取代烯基和取代炔基及其类似物的组;Y1是一个连接基团,该连接基团与一个位点上的R基团共价连接,并在另一个独立位点上连接到A;Y2是一个连接基团,该连接基团在两个独立位点上与两个R基团共价连接,并在另一个独立位点上连接到A;Y3是一个连接基团,该连接基团在三个独立位点上与三个R基团共价连接,并在另一个独立位点上连接到A。本发明公开了两亲性前药的自组装成反向亲水相,特别是六角形、立方体和海绵相。在优选实施例中,A是多巴胺或5-氟尿嘧啶前药。
