A series of head to head linked dimers of heterocyclic amino acids has been prepared for investigation of affinity and selectivity in binding to the minor groove of DNA. The selection of targets for synthesis was led by computer based design. Several novel dicarboxylic acid linkers including indoles, phenanthrenes, a fluorenone, and a bisbenzothiophene have been included. Analysis of binding to DNA

Phenanthrenyl-based metallocycles are mechanically interlinked to form an infinite catenated chain. The formation of the catenane is governed by an infinite Ïâ¯Ï stack involving the phenanthrenyl moieties.

Cross-linked proteins and peptides, and methods of making and uses of such cross-linked proteins and peptides. The cross-linked proteins and peptides have rigid, distance-matching bismethylene aryl cross-linking moieties. Compositions comprising the cross-linked proteins and peptides can be used as pharmaceutical delivery formulations. The cross-linked proteins and peptides can have improved properties, such as cell permeability, as compared to the parent protein or peptide.

We report the synthesis of a series of distance-matching aryl and vinylaryl cross-linkers for constructing stapled peptides containing cysteines at i,i+7 positions. Langevin dynamics simulation studies helped to classify these cross-linkers into two categories: the rigid cross-linkers with narrower S S distance distribution and the flexible cross-linkers with wider S S distance distribution. The stapled Noxa BH3 peptides with the flexible distance-matching cross-linkers gave the highest degree of helicity as well as the most potent inhibitory activity against Mcl-1. However, the stapled peptides with the highest hydrophobicity showed the most efficient cellular uptake. Together, this work illustrates the divergent nature of binding affinity and cellular uptake, and the vital importance of choosing appropriate cross-linkers in constructing stapled peptides with the drug-like properties.
