The present invention describes pyridazinone compounds of formula (I) which are cyclooxygenase (COX) inhibitors, and in particular, are selective inhibitors of cyclooxygenase-2 (COX-2). COX-2 is the inducible isoform associated with inflammation, as opposed to the constitutive isoform, cyclooxygenase-1 (COX-1) which is an important 'housekeeping' enzyme in many tissues, including the gastrointestinal (GI) tract and the kidneys. The selectively of these compounds for COX-2 minimizes the unwanted GI and renal side-effects seen with currently marketed non-steroidal anti-inflammatory drugs (NSAIDs).
The present invention is directed to pyridazinone compounds of formula (I) and furan compounds of formula (II), pharmaceutical compositions of compounds of formula (I) and (II), kits containing these compounds, methods of syntheses, and a method of treatment of a proliferative disease in a subject by administration of a therapeutically effective amount of a compound of formulae (I) or (II). Both classes of compounds were identified through screening of a collection of small molecule libraries.

A novel series of pyridazinone-functionalized phenylalanine analogues was prepared and evaluated for inhibition of cellular adhesion mediated by alpha(4)beta(1)/VCAM-1 and alpha(4)beta(7)/MAdCAM-1 interactions. Concise syntheses were developed and applied for exploration of structure-activity relationships pertaining to the pyridazinone ring as well as the N-acyl phenylalanine scaffold. Potent dual antagonists of alpha(4)beta(1) and alpha(4)beta(7) were generated from an amide subseries; antagonists selective for alpha(4)beta(7) were identified from urea and carbamate-based subseries. The pharmacokinetic properties of selected members of the series have been determined in rats and demonstrate that the use of ester prodrugs and alterations to the amide linkage can lead to improved oral bioavailability in this series. An alpha(4),beta(7)-selective member of the carbamate subseries (36c), upon oral admininstration, demonstrated in vivo efficacy in the mouse DSS colitis model.

Suzuki reactions on chloropyridazinones: an easy approach towards arylated 3(2 H )-pyridazinones
The synthesis of 4-aryl-5-methoxy-, 5-aryl-4-methoxy- and 4,5-diaryl-3(2H)-pyridazinones via Suzuki palladium-catalysed cross-coupling reactions with the corresponding chloro-3(2H)-pyridazinones is described. (C) 2001 Elsevier Science Ltd. All rights reserved.
