We screened 10,000 heterocyclic small molecules and identified a novel hit core skeleton of 3-(8-chloro-6-(trifluoromethyl) imidazo[1,2-a]pyridine-2-yl)phenyl acetate derivatives. It has been selected as a potential glucagon-like peptide 1 receptor (GLP-1R) activator and demonstrated its effects in increasing GLP-1 secretion, and thereby increasing the glucose responsiveness in both in vitro and pharmacology analyses. Further studies are currently underway to optimize the potency and selectivity of 3-(8-chloro-6-(trifluoromethyl)imidazo[1,2-a]pyridine-2-yl)phenyl acetate derivatives (hit compounds 2 and 8), and address their in vivo efficacy and therapeutic potential. These molecules may serve as useful evidence showing that compounds with a 3-(8-chloro-6-(trifluoromethyl)imidazo[1,2-a]pyridine-2-yl)phenyl acetate moiety are selective GLP-1R agonists, and have potential as anti-diabetic treatment agents.

We report the solid-phase library construction of 222 number of a novel N-[alkyl sulfonamido-spiro(2H-1-benzopyran-2,4-piperidine)-6-yl] substituted amide 1A and amine 1B derivatives. The polymer-bound N-[alkylsulfonamido-spiro(2H-1-benzopyran-2,4-piperidine)-6-yl] substituted amide 9 and amine 10 derivatives were obtained by first diversity generation with various acid chlorides and alkyl halides. Further reactions on the resins 9 and 10 with substituted sulfonyl chlorides produced the desired N-[alkylsulfonamido-spiro(2H-1-benzopyran-2,4-piperidine)-6-yl] substituted amide 1A and amine 1B analogues.
