(In the formula, R1, R2, R6, and R7 each independently represents hydrogen, C1-5 alkyl, etc., provided that they may be bonded to each other; R3, R4, and R5 each independently represents C1-5 alkyl or C5-8 aryl; Y and Z each independently represents atoms necessary for the formation of a 5- or 6-membered heterocycle; m and n each is 0 or 1; Q represents a physiologically acceptable anion; and k is an integer of 0-2 which is necessary for making the charge of the whole molecule zero.) |
