(EN) Fused polycyclic 2-aminopyrimidines of formula (1) wherein Ar is an optionally substituted aromatic or heteroaromatic group; X is a carbon or nitrogen atom; Y is a carbon or nitrogen atom; Z is a linker group; A together with X and Y forms an optionally substituted monocyclic or bicyclic aromatic or heteroaromatic group; and the salts, solvates, hydrates and N-oxides thereof are described. The compounds are potent and selective inhibitors of the protein tyrosine kinases p56lck and p59fyn and are of use in the prophylaxis and treatment of immune diseases, hyperproliferative disorders and other diseases in which inappropriate p56lck and/or p59fyn activity is believed to have a role.(FR) L'invention concerne des 2-aminopyrimidine polycycliques fondus, ainsi que leurs sels, solvates, hydrates et N-oxydes, et représentés par la formule (1), dans laquelle Ar est un groupe aromatique ou hétéro-aromatique éventuellement substitué; X est atome de carbone ou d'azote; Y est atome de carbone ou d'azote; Z est un groupe lieur; A, X et Y forment un groupe aromatique ou hétéro-aromatique, monocyclique ou bicyclique, éventuellement substitué. Ces composés, qui sont des inhibiteurs puissants et sélectifs des protéines tyrosines kinases p561ck et p59fyn, conviennent particulièrement à la prophylaxie et au traitement de maladies immunitaires, de maladies hyperproliférantes et d'autres maladies dans lesquelles on pense qu'une activité inappropriée de la p561ck et/ou p59fyn joue un rôle.

Mitogen-activated protein kinase (MAPK) phosphatase 5 (MKP5) is responsible for regulating the activity of the stress-responsive MAPKs and has been put forth as a potential therapeutic target for a number of diseases, including dystrophic muscle disease a fatal rare disease which has neither a treatment nor cure. In previous work, we identified Compound 1 (3,3-dimethyl-1-((9-(methylthio)-5,6-dihydrothieno[3
A number of new furo and thienoquinolinones carrying an electron-withdrawing function or unsubstituted at the position 3 were synthesized in order to obtain new potential photochemotherapeutic agents with increased anti proliferative activity and decreased toxic side effects. Our interest in studying the SAR of these derivatives also prompted us to investigate the influence of N-methylation on biological activity, by preparing N-methyl derivatives. The antiproliferative activity of all the newly synthesized compounds was evaluated and compared to 8-methoxypsoralen (8-MOP), the drug widely used in PUVA-therapy. The 3-unsubstituted thienoquinolinones were generally the most potent derivatives, followed by the furo-analogues. In particular. the unsubstituted thieno[2.3-h]quinoline-2(1H)one showed the highest activity in T2 bacteriophage, HeLa cells and Ehrlich cells tests. All the compounds, assayed on Escherichia coli WP2 TM9, showed a similar mutagenic activity, very close to that of 8-MOP. Except for 2-oxo-1,2-dihydrothieno[2.3-h]quinoline-3-carboxylic acid, which appeared to be very effective, all compounds generated singlet oxygen to slightly larger amounts when compared to 8-MOP. The N-methyl analogues only induced moderate skin erythemas on albino guinea pigs, while all other derivatives appeared to be entirely inactive. On the basis of these results, the unsubstituted thieno[2,3h]quinoline 2(1H)one seems to be the most interesting potential drug for PUVA photochemotherapy and photopheresis.
