Abstract:
The present invention provides a compound represented by formula (I) or a pharmaceutically acceptable salt thereof as a cationic lipid, and the like.

Claim (Index 1):
A compound represented by formula (I): wherein R 1  is a hydrogen atom, C1-C3 alkyl, hydroxyC2-C4 alkyl, di-C1-C3 alkylaminoC2-C4 alkyl, formula (A): wherein R 2  and R 3  are, the same or different, a hydrogen atom or C1-C3 alkyl, or R 2  and R 3 , together with the nitrogen atom to which they are attached, may form a C2-C6 nitrogen-containing heterocycle, and n 3  is an integer from 2 to 6, or formula (B): wherein R 4  and R 5  are, the same or different, a hydrogen atom or C1-C3 alkyl, or R 4  and R 5 , together with the nitrogen atom to which they are attached, may form a C2-C6 nitrogen-containing heterocycle, and n 4  is an integer from 1 to 6; n 1  is an integer from 0 to 4; n 2  is an integer from 1 to 4, provided that the case where n 1  is 0 and n 2  is 1 is excluded; Z 1  is, independently for each carbon atom bonded thereto, a hydrogen atom or C1-C3 alkyl; Z 2  is, independently for each carbon atom bonded thereto, a hydrogen atom or C1-C3 alkyl; A 1  and A 2  are, the same or different, linear or branched C8-C20 alkylene or C8-C20 alkenylene, or C6-C18 alkyleneoxyC1-C3 alkylene or C6-C18 alkenyleneoxyC1-C3 alkylene; M 1  and M 2  are, the same or different, selected from the group consisting of \u2014OC(O)\u2014, \u2014C(O)O\u2014, \u2014SC(O)\u2014, \u2014C(O)S\u2014, \u2014OC(S)\u2014, \u2014C(S)O\u2014, \u2014SS\u2014, \u2014C(R 6 )\u2550N\u2014, \u2014N\u2550C(R 6 )\u2014, \u2014C(R 6 )\u2550N\u2014O\u2014, \u2014O\u2014N\u2550C(R 6 )\u2014, \u2014N(R 6 )C(O)\u2014, \u2014C(O)N(R 6 )\u2014, \u2014N(R 6 )C(S)\u2014, \u2014C(S)N(R 6 )\u2014, \u2014N(R 6 )C(O)N(R 7 )\u2014, \u2014N(R 6 )C(O)O\u2014, \u2014OC(O)N(R 6 )\u2014, and \u2014OC(O)O\u2014; R 6  and R 7  are, the same or different, a hydrogen atom or C1-C4 alkyl; and B 1  and B 2  are, the same or different, linear or branched C1-C16 alkyl or C2-C16 alkenyl or a pharmaceutically acceptable salt thereof.
