Abstract
Digestive tract contractile motion stimulant contg. an erythromycin A, B, C, D, E or F deriv. of formula (I), or its salt, is new. R1 = H or opt. substd. acyl; R2 = H, acyl or alkyl opt. substd.; R3 = H or Me; R4 = H or OH; R = NR20R21 or (+)NR22R23R24 X(-); R20 H H, lower alkyl or cycloalkyl; R21 = H, lower alkyl, cycloalkyl, lower alkenyl or lower alkynyl opt. substd.; or NR20R21 = cyclic alkylamino radical; R22 = lower alkyl; R23, R24 = lower alkyl, cycloalkyl, lower alkenyl or lower alkynyl opt. substd.; or NR23R24 = cyclic alkylamino radical X = anion; A = e.g. gp. of formula (II) or (III) Z = e.g. -CH(OR5)-CMe(OR6)-, -CH(OR7)-CHMe-, =CH-CMe(OH)- where R5, R7 = H, acyl or alkyl opt. substd.; R6 = H, acyl of a lower carboxylic acid or alkyl opt. substd. by alkylthio; either R11=R12 = H; or R11+R12 = bond.
