Exploring Passive Permeability Profiles of Cyclic Heptapeptide Chemical Space Uncovers Bioactivity of Mortiamide Scaffold Driven by Colloidal Aggregation

open access: yesChemBioChem, Volume 27, Issue 9, 14 May 2026.
A comprehensive stereochemical and physicochemical survey of cyclic heptapeptide chemical space reveals that the mortiamide natural product scaffold possesses intrinsically low aqueous solubility and forms amyloid‐like fibril aggregates. Multiple orthogonal assays demonstrate that the observed cytotoxicity arises from colloidal aggregation rather than ...
