DNA-encoded combinatorial synthesis provides efficient and dense coverage of chemical space around privileged molecular structures. The indole side chain of tryptophan plays a prominent role in key, or “hot spot”, regions of protein–protein interactions. A DNA-encoded combinatorial peptoid library was designed based on the Ugi four-component reaction by employing tryptophan-mimetic indole side chains to probe the surface of target proteins. Several peptoids were synthesized on a chemically stable hexathymidine adapter oligonucleotide “hexT”, encoded by DNA sequences, and substituted by azide-alkyne cycloaddition to yield a library of 8112 molecules. Selection experiments for the tumor-relevant proteins MDM2 and TEAD4 yielded MDM2 binders and a novel class of TEAD-YAP interaction inhibitors that perturbed the expression of a gene under the control of these Hippo pathway effectors.

The systemic investigation of the structural impacts of side chains on the pH- and thermo-responsiveness of tertiary amine functionalized poly(l-glutamate)s (TA-PGs) was carried out. The TA-PGs polymers were effectively synthesized by Cu(I)-catalyzed azide-alkyne cycloaddition click reaction of azido tertiary amines with poly(γ-propargyl-l-glutamate) (PPLG). Turbimetric measurements were performed to characterize the pH- and temperature-induced phase transition of TA-PGs in aqueous solution, which suggested a structural dependence of the properties on the N-substituted groups and the "linkers" between 1,2,3-triazole ring and the tertiary amine groups in the side chains. In detail, the pH responsive properties of TA-PGs were basically determined by the hydrophobicity of the N-substituted groups in the side chains and the pH transition point (pHt) decreased as the increasing hydrophobicity of the N-substituted groups, while the temperature-responsiveness of TA-PGs were affected by either the N-substituted groups or the "linkers." TA-PGs with a moderate N-substituted amine group (e.g., DEA, PR, and PD) or a branched "linker" (e.g., iso-propylene and 2-methylpropylene group) were more likely to express the LCST-type phase transition tuned by pH variation. These structure-property relationships revealed in this study would help to develop the applications of TA-PGs in smart drug delivery systems. Copyright
