Overview

Review outlines drug discovery lessons from oral small-molecule GLP-1 receptor agonists in metabolic disease, highlighting rational design frameworks for next-generation therapies.

Key Points

To analyze first-generation oral small-molecule GLP-1 receptor agonists, assess their structural and clinical challenges, and establish a blueprint for designing next-generation nonpeptidic drugs targeting complex GPCRs.
Evaluated clinical candidates including danuglipron, lotiglipron, DA-302168S, and orforglipron as case studies for small-molecule receptor activation.
Synthesized molecular design and translational strategies, focusing on peptidomimetics, multi-target agonists, allosteric cooperativity, screening cascades, and formulation optimization.
Clinical progress of candidates like orforglipron demonstrates that nonpeptidic small molecules can effectively activate the GLP-1 receptor and overcome previous peptide-only barriers.
Addressing remaining clinical bottlenecks requires leveraging orthosteric and allosteric cooperativity, developing multi-target agonists, and refining preclinical species selection and safety assessments.
