Claim 1
Independent Claim
115 words
A compound of the formula ##STR37## wherein R 1 is hydrogen or methyl, and R 2 is a substituent of the formula ##STR38## wherein R 4 , R 5 and R 6 are the same or different and are hydrogen or lower alkyl or R 4 and R 5 are joined to form a ring in II and IIa, which rings are unsubstituted or mono- or poly-substituted by alkyl, hydroxy, carboxy or di-(lower)-alkylamino, m is 2 or 3, and n is 1, 2 or 3 or a salt thereof or a zwitterion thereof, with the proviso that when R 1 is hydrogen and the group containing it has R- configuration, R 2 is not acetylaminoethyl.
