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: —(CH
2
)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.
本发明涉及一种由通式(I)表示的化合物或其盐:其中R1、R2和R3中的任意一个表示公式表示的基团:—(CH2)m-NR11R12(其中m为1或2;R11和R12独立地表示氢原子或C1-6烷基或可能与R11和R12结合的氮原子一起形成4-或5-成员环状基团);剩余的两个或R1、R2和R3独立地表示公式表示的基团:—(O)n-R21(其中n为0或1;R21表示氢原子、C1-6烷基、C2-6烯基、C2-6炔基等);R4表示可能具有取代基的C1-6烷基。
