Discovery of novel N-(5-(arylcarbonyl)thiazol-2-yl)amides and N-(5-(arylcarbonyl)thiophen-2-yl)amides as potent RORγt inhibitors

Novel series of N-(5-(arylcarbonyl)thiazol-2-yl)amides and N-(5-(arylcarbonyl)thiophen-2-yl)amides were discovered as potent retinoic acid receptor-related orphan receptor-gamma-t (RORγt) inhibitors. SAR studies of the RORγt HTS hit 6a led to identification of thiazole ketone amide 8h and thiophene ketone amide 9g with high binding affinity and inhibitory activity of Th17 cell differentiation. Compound 8h showed in vivo efficacy in both mouse experimental autoimmune encephalomyelitis (EAE) and collagen induced arthritis (CIA) models via oral administration.

Reaction of 2-Thiophenamines with Hydrazine

Depending on their substituents 2-thiophenamines react with hydrazine hydrate on different ways: Hydrazinolysis of the ester 1 yields the 2-amino-3-thiophenecarbohydrazide 2. 4-Phenyl-2-thiophenamine (4) is converted into the 2(5H)-thiophenone hydrazone 5 by exchange of the amino group.The thiophenamines 7, 9, 12 undergo ring transformation to yield pyridazine derivatives, the N,N'-bis(dihydro-3-pyridazinyl)hydrazine 8, the 3-pyridazinylhydrazine 10, and the pyrazolopyridazine 13.From 10 the 1,2,4-triazolopyridazine 11 is obtained.
