Synthesis of Hybrid Cyclic Peptoids and Identification of Autophagy Enhancer

Cyclic peptoids are potential candidates for diverse biological activities. However, applications of cyclic peptoids are limited by the synthetic difficulties, conformational flexibility of large cyclic peptoids, and lack of secondary amide in the backbone. Herein, an elegant methodology for the synthesis of small and medium-size cyclic hybrid peptoids is developed. α N-Alkyl and α N-acyl substituents in N-(2-aminoethyl)glycine monomers enforce...
