N‐ or C‐methylation in natural and synthetic cyclic peptides can increase membrane permeability, but it remains unclear why this happens in some cases but not others. Here we compare three‐dimensional structures for cyclic peptides from six families, including isomers differing only in the location of an N‐ or Cα‐methyl substituent. We show that a single methyl group only increases membrane permeability

Backbone stereochemistry of cyclic peptides has been reported to have a great influence on microsomal stability and membrane permeability, two important factors that determine oral bioavailability. Here, we comprehensively investigated the correlation between the backbone stereochemistry of cyclic hexapeptide stereoisomers and their stability in liver microsomes, as well as passive membrane permeability
