Synthesis of ortho-functionalized 4-aminomethylpyridazines as substrate-like semicarbazide-sensitive amine oxidase inhibitors.
A series of 4-aminomethylpyridazines and -pyridazin-3(2H)-ones ("diaza-benzylamines"), bearing alkylamino side chains in ortho position relative to the CH(2)NH(2) unit, was synthesized by catalytic hydrogenation of the corresponding nitriles in strongly acidic medium. N-Benzyl protecting groups either at the pyridazinone ring nitrogen or at an exocyclic nitrogen were selectively removed hydroge...
متن کاملOrigins of serum semicarbazide-sensitive amine oxidase.
Semicarbazide-sensitive amine oxidases (SSAO) are enzymes that are capable of deaminating primary amines to produce aldehyde, ammonia, and hydrogen peroxide. This activity has been associated with vascular adhesion protein-1 (VAP-1) and is found in the serum, endothelium, adipose, and smooth muscle of mammals. Circulating SSAO activity is increased in congestive heart failure, diabetes, and inf...
متن کاملDesign, synthesis, and biological evaluation of semicarbazide-sensitive amine oxidase (SSAO) inhibitors with anti-inflammatory activity.
In an attempt to examine the effect of inhibition of semicarbazide-sensitive amine oxidase (SSAO; EC 1.4.3.6, also known as VAP-1) as a novel anti-inflammatory target, the structure/mechanism based design and synthesis of a series of novel hydrazino-containing small molecules are described. The in vitro biological results show that compounds 4a,c are highly potent SSAO inhibitors with notable s...
متن کاملSemicarbazide-sensitive amine oxidase and kidney disease.
With better understanding of the molecular mechanisms underpinning chronic kidney disease, the roles of inflammation and fibrosis are becoming increasingly inseparable. The progression of renal disease is characterized by pathomorphological changes that consist of early inflammatory responses followed by tubulointerstitial fibrosis, tubular atrophy, and glomerular and vascular sclerosis. Curren...
متن کاملAnti-inflammatory effects of inhibiting the amine oxidase activity of semicarbazide-sensitive amine oxidase.
Human semicarbazide-sensitive amine oxidase (SSAO) or vascular adhesion protein-1 (VAP-1) is a copper-containing amine oxidase (AOC3, EC 1.4.3.6) that has both enzymatic and adhesive function. SSAO catalyzes the oxidative deamination of primary amines, resulting in the formation of the corresponding aldehyde and release of hydrogen peroxide and ammonia. Membrane-bound SSAO is an inflammation-in...
