Abstract
Hydrocinnamic acid derivatives of the formula ##STR1## wherein one or two of the symbols R.sup.1 to R.sup.4 are halogen or methoxy and the others are hydrogen; PA1 R.sup.5 is hydrogen or phenyl; PA1 R.sup.6 is a residue of the formula ##STR2## R.sup.7 is (C.sub.1 -C.sub.4)-alkyl, (C.sub.2 -C.sub.5)-alkanoylamino-(C.sub.2 -C.sub.5)-alkyl, amino or (C.sub.1 -C.sub.4)-alkoxyphenyl; PA1 R.sup.8 and R.sup.9 each, independently, are hydrogen or (C.sub.1 -C.sub.4)-alkyl; PA1 R.sup.10 is hydrogen and R.sup.11 is hydroxy or R.sup.10 and R.sup.11 taken together are oxo; PA1 R.sup.12 is hydrogen, (C.sub.1 -C.sub.10)-alkyl, pyridylmethyl or carbamoylmethyl; PA1 R.sup.13 is hydrogen, (C.sub.1 -C.sub.4)-alkyl and R.sup.14 is hydrogen, (C.sub.1 -C.sub.4)-alkyl, pyridyl, phenyl-(C.sub.1 -C.sub.4)-alkyl, carboxy-(C.sub.1 -C.sub.4)-alkyl, carbamoyl-(C.sub.1 -C.sub.4)-alkyl, (C.sub.1 -C.sub.4)-alkoxy carbonyl-(C.sub.1 -C.sub.4)-alkyl, di-(C.sub.1 -C.sub.4)-alkoxy carbonyl-C.sub.2 -C.sub.5)-alky, piperidino-C.sub.2 -C.sub.4)-alkyl or halopyridinecarboxamido-(C.sub.2 -C.sub.4)-alkyl or R.sup.13 and R.sup.14 taken together with the nitrogen atom are 4-(C.sub.1 -C.sub.4)-alkyl-piperazin-1-yl, as well as …
