Synthesis and anti-angiogenic activity of 6-(1,2,4-thiadiazol-5-yl)-3-amino pyridazine derivatives

General screening for inhibitors of microvessel growth in vitro in the rat aortic ring assay led to the discovery of a novel series of thiadiazole pyridazine compounds with potential anti-angiogenic activity. Chemical optimization produced orally active compounds with potent in vitro and in vivo anti-angiogenesis and anti-tumor activities.

Angiogenesis inhibiting 5-substituted-1,2,4,-thiadiazolyl derivatives

This invention concerns compounds of formula the N-oxide forms, the pharmaceutically acceptable acid addition salts and stereochemically isomeric forms thereof, wherein X is CH or N; R1 is hydrogen, C1-6alkyl, C1-6alkyloxy, C1-6alkylthio, amino, mono- or di(C1-6alkyl)amino, Ar1, Ar1NH—, C3-6cycloalkyl, hydroxymethyl or benzyloxymethyl; R2 is hydrogen, C1-6alkyl, amino, aminocarbonyl, mono- or di(C1-6alkyl)amino, C1-6alkyloxycarbonyl, C1-6alkylcarbonylamino, hydroxy or C1-6alkyloxy; R3, R4 and R5 are each independently selected from hydrogen, halo, C1-6alkyl, C1-6alkyloxy, trifluoromethyl, nitro, amino, cyano, azido, C1-6alkyloxyC1-6alkyl, C1-6alkylthio, C1-6alkyloxycarbonyl or Het1; is Ar2, Ar2CH2— or Het2; Ar1 and Ar2 optionally substituted phenyl; Het1 and Het2 are optionally substituted monocyclic heterocycles; having angiogenesis inhibiting activity; their preparation, compositions containing them and their use as a medicine.
