Abstract
The subject of the invention is indolin-2-one derivatives of formula: ##STR1## in which: W represents a --CH.sub.2 -- or --SO.sub.2 -- group; PA1 Cy forms, with the carbon to which it is bonded, a non-aromatic, saturated or unsaturated C.sub.3 -C.sub.12 hydrocarbon ring which is optionally condensed or substituted by one or a number of (C.sub.1 -C.sub.7)alkyl groups, it being possible for the said groups to substitute the same carbon atom one or a number of times, or by a C.sub.3 -C.sub.6 spirocycloalkyl; PA1 T represents a (C.sub.1 -C.sub.4)alkylene which is optionally interrupted by a (C.sub.3 -C.sub.6)cycloalkylene, the said alkylenes optionally being substituted one or a number of times on the same carbon atom by a (C.sub.1 -C.sub.3)alkyl; or alternatively T represents a direct bond; PA1 Z represents in particular an amino group; PA1 R.sub.1 and R.sub.2, as well as R.sub.3 and R.sub.4, are either hydrogen or substituents, such as, for example, a halogen, an alkyl, and the like.
