Abstract: The invention concerns novel benzamides and their pharmacologically acceptable salts which are useful as gastromotor agents and correspond to the following general formula (I): ##STR1## in which: R.sub.1 is lower alkyl, lower alkenyl or a hydrogen atom;R.sub.2 is alkyl, lower alkenyl, benzyl, cycloalkylalkyl, cycloalkenylalkyl or a hydrogen atom;R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7 and R.sub.8 each are lower alkyl or a hydrogen atom, andX is a halogen atom.

Abstract: The invention provides compounds of formula: ##STR1## in which R=H, halogen, alkyl, alkyloxy, alkythio, NH.sub.2, alkylamino, dialkylamino or CF.sub.3, R.sub.3 =H or alkyl, either R.sub.4 and R.sub.5 =H and R.sub.1 and R.sub.2 =H or alkyl, optionally substituted by alkenyl (2 to 4 C) or alternatively R.sub.1 and R.sub.2 form together a saturated heterocyclic ring containing 4 to 7 ring members and optionally containing another heteroatom such as O, S or N optionally substituted by alkyl, or R.sub.4 =H, R.sub.1 =H or alkyl and R.sub.2 and R.sub.5 together form an alkylene (3 to 4 C) radical and (i) either A=alkyl or phenyl which is unsubstituted or substituted by one or two substituents chosen from halogen, alkyl, alkyloxy, alkylthio, NH.sub.2, alkylamino, dialkylamino, NO.sub.2 or CF.sub.3 or alternatively A=pyridyl, benzyl or cycloalkyl (3 to 6C), Y=S, SO or SO.sub.2 or a radical: ##STR2## in which R.sub.6 =H or alkyl and R.sub.

Abstract: Benzenesulfonamides with a substituted-alkyl-S(O).sub.n -substituent are carbonic anhydrase inhibitors useful in the treatment of elevated intraocular pressure.

Abstract: The invention relates to certain substituted phenoxypropionaldehyde derivatives, formulations of said derivatives and the use thereof for preemergence or postemergence control of noxious plants, i.e., weeds.
