Disclosed is a compound represented by the general formula (I) or a salt thereof:
wherein any one of R1, R2 and R3 represents a group represented by the formula: -(CH2)m-NR11R12 (wherein m is 1 or 2; and R11 and R12 independently represent a hydrogen atom or a C1-6 alkyl group or may, together with a nitrogen atom to which R11 and R12 are bound, form a 4- or 5-membered cyclic group); the remaining two or R1, R2 and R3 independently represent a group represented by the formula: -(O)n-R21 (wherein n is 0 or 1; and R21 represents a hydrogen atom, a C1-6 alkyl group, a C2-6 alkenyl group, a C2-6 alkynyl group, or the like); and R4 represents a C1-6 alkyl group which may have a substituent or the like.
本发明公开了通式 (I) 所代表的化合物或其盐:
其中 R1、R2 和 R3 中的任何一个代表由式表示的基团:-(CH2)m-NR11R12(其中m为1或2;R11和R12独立地代表氢原子或C1-6烷基,或可与R11和R12所结合的氮原子一起形成4或5元环状基团);其余两个或R1、R2和R3独立地代表由式表示的基团:-(O)n-R21(其中 n 为 0 或 1;R21 代表氢原子、C1-6 烷基、C2-6 烯基、C2-6 炔基或类似基团);以及 R4 代表可具有取代基或类似基团的 C1-6 烷基。
