The invention provides a compound of the formula I (see formula I) wherein Ar represents pyridyl; R1 represents lower alkyl, cycloalkyl, carbocyclic-lower alkyl, lower alkoxy-lower alkyl, or halogen-lower alkyl; R2 represents hydrogen or lower alkyl; R3 and R4 represent independently hydrogen, lower alkyl, lower alkoxy, halogen, hydroxy, acyloxy, lower alkoxy-lower alkoxy, trifluoromethyl or cyano; or R3 and R4 together on adjacent carbon atoms represent lower alkylenedioxy; n represents an integer from 1 to 5; wherein cycloalkyl represents a saturated cyclic hydrocarbon, unsubstituted or substituted by lower alkyl, which contains 3 to 10 ring carbons; a pharmaceutically acceptable prodrug derivative thereof in which the CONHOH group is derivatised in the form of an O-acyl wherein acyl is derived from an organic carboxylic acid, carbonic acid or carbamic acid; or a substituted or unsubstituted O-benzyl derivative; or a pharmaceutically acceptable salt thereof. It can be used as anti- inflammatory, for example in treatment of osteoarthritis or rheumatoid arthritis, or as an antitumor agent, for example in treatment and prevention of tumor growth, tumor metastasis, tumor invasion and progression.

L'invention concerne des composés de la formule (I). Dans cette formule, Ar, n, R1, R2, R3 et R4 sont comme défini dans la description. L'invention concerne également des précurseurs de ces composés acceptables sur le plan pharmaceutique et des sels de ces composés acceptables sur le plan pharmaceutique. Ces produits ont des propriétés pharmaceutiques très utiles, en particulier comme inhibiteurs du facteur nécrosant des tumeurs alpha et des métalloprotéinases agissant sur les tissus de support. Par conséquent, on peut les uiliser pour le traitement d'un spectre de maladies, en particulier comme agents anti-inflammatoires pour le traitement de l'arthrose, la polyarthrite rhumatoïde ou comme agents antitumoraux, par exemple pour le traitement et la prévention de la croissance de tumeurs et de métastases, l'invasion ou la progression de tumeurs. Ces composés sont préparés par des procédés connus.
