Description
The present invention relates to novel derivatives of indolin-2-one, a process for their preparation and pharmaceutical formulations including them, which are potent and selective ligands of oxytocin receptors and can therefore be used as an active ingredient in pharmaceutical formulations, particularly in obstetrics and gynecology.
Oxytocin (OT) is a neurohypophyse hormone with a cyclic nonapeptide structure similar to arginine vasopressin (AVP).Oxytocin receptors are mainly found in the smooth muscle of the uterus and on the myoepithelial cells of the mammary glands.Oxytocin plays an important role in childbirth as it is involved in uterine muscle contraction and lactation.Oxytocin receptors are also located in other peripheral tissues and in the central nervous system; therefore, oxytocin can have effects in the cardiovascular, renal, endocrine or behavioral domains.
Indolin-2-one derivatives have been described in some patent applications as ligands of vasopressin receptors and possibly oxytocin receptors, including patent applications WO 93/15051, EP 636608, EP 636609, WO 95/18105, WO 97/15556 and WO 98/25901.
It has now been found that some indolin-2-one derivatives are potent and selective ligands of oxytocin receptors.

When a compound of the invention has one or more asymmetrical carbons, the optical isomers of that compound are an integral part of the invention. When a compound of the invention has a stereoisomer, e.g. axial-equatorial or Z-E, the invention includes all stereoisomers of that compound.
The present invention includes compounds of formula (I) as pure isomers but also as mixtures of isomers in any proportion.
The compounds (I) are isolated as pure isomers by conventional separation techniques: recrystallizations fractionated from a racemic salt with an acid or an optically active base, the principle of which is well known, or conventional techniques of chiral or nonchiral phase chromatography may be used.
The compounds of formula (I) above also include those in which one or more hydrogen, carbon or halogen atoms, in particular iodine, chlorine or fluorine, have been replaced by their radioactive isotope e.g. tritium or carbon-14. Such labelled compounds are useful in research, metabolism or pharmacokinetics, in biochemical assays as receptor ligands.
The functional groups possibly present in the molecule of formula (I) compounds and in the reaction intermediates can be protected either permanently or temporarily by protective groups that ensure a univocal synthesis of the expected compounds. The protective and deprotective reactions are performed according to techniques well known to man of the art. By temporary protective group of amines or alcohols are meant protective groups such as those described in Protective Groups in Organic Synthesis, Greene T.W. and Wuts P.G.M., Ed. Wiley Intersciences 1999 and in Protecting Groups, Kocienski P.J., 1994, Georgeme Thi Verlag.
Examples of temporary protective groups of amines include: benzyls, carbamates (such as tert-butyloxycarbonyl cleasable in acidic media, benzyloxycarbonyl cleasable by hydrogenolysis); carboxylic acids: alkyl esters (such as methyl or ethyl, tert-butyl hydrolysable in basic media or acids) and hydrogenolysable benzylic groups; alcohols or phenols such as tetrahydropyranyl, methyloxymethyl or methyl ether, tert-butyl and benzyl; carbonyl derivatives such as linear acetals or cyclic groups described as 1,3-dioxylan or 1,3-dioxylan; and the well-known protective groups referred to above, the 2-cylindric groups.
The man of art will be able to choose the appropriate protective groups.The compounds of formula (I) may contain precursor groups of other functions which are generated later in one or more other steps.
