Despite the continuous efforts, the current repertoire of detergents is still far from sufficient for the biophysics studies of membrane proteins (MPs). Toward the rapid expansion of detergent diversity, we herein report a new strategy based on Ugi reaction mediated modular assembly. Structural varieties, including hydrophobic tails and hydrophilic heads, could be conveniently introduced from the multiple reaction components. New detergents then were comprehensively evaluated in the physical properties and preliminarily screened by the thermal stabilization for a transporter MsbA and a spectrum of G protein-coupled receptors (GPCRs). For the glucagon-like peptide-1 receptor (GLP-1R), a class B GPCR, detergent M-23-M finally stood out in a second evaluation for the maintenance of homogeneity and was further illustrated its application in the improvement of NMR study. Besides the promising utility in the MP study, the current results exhibit intriguing structural-physical relationship that would allow the guidance in the tuning of detergent properties in the future. © 2022 Wiley-VCH GmbH.
