Discovery of Second Generation RORγ Inhibitors Composed of an Azole Scaffold
摘要:
Starting from a previously reported ROR gamma inhibitor (1), successive efforts to improve in vivo potency were continued. Introduction of metabolically beneficial motifs in conjunction with scaffold hopping was examined, resulting in discovery of the second generation ROR gamma inhibitor composed of a 4-(isoxazol-3-yl)butanoic acid scaffold (24). Compound 24 achieved a 10-fold improvement in in vivo potency in a mouse CD3 challenge model along with significant anti-inflammatory effects in a mouse dermatitis model.

Sulfone 15, derived from d-glutamic acid, and aldehyde 23, made by diastereoselective alkylation, were linked and elaborated into enamine sulfone 33. This underwent 5-exo radical cyclization to 34, which was desulfonylated to (−)-35, a compound that represents the spirobicyclic core of halichlorine.
Practical Synthesis of Chiral 3-(Hydroxyiminomethyl)adipic Acid, a Key Intermediate of the ROR-γ Inhibitor JTE-151, via Crystallization-Induced Dynamic Resolution
A practical six-step process for the production of chiral 3-(hydroxyiminomethyl)adipic acid 4 featuring highly efficient crystallization-induced dynamic resolution (CIDR) as the key step is reported. This compound was converted to isoxazole 23, an API starting material candidate of the ROR-γ inhibitor JTE-151, via isoxazole core construction by 1,3-dipolar cycloaddition and subsequent Ag2O-catalyzed
