A chemically fueled supramolecular glue for self-healing gels.

Chemically fueled supramolecular materials offer unique properties that include spatial and temporal control and even the ability to self-heal. Indeed, a few studies have demonstrated the ability to self-heal, however, the underlying mechanisms remain unclear. Here, we designed a peptide that forms a fibrillar network upon chemical fueling.

Picomolar FKBP inhibitors enabled by a single water-displacing methyl group in bicyclic [4.3.1] aza-amides.

Methyl groups can have profound effects in drug discovery but the underlying mechanisms are diverse and incompletely understood. Here we report the stereospecific effect of a single, solvent-exposed methyl group in bicyclic [4.3.

Dissipative assemblies that inhibit their deactivation.

Dissipative self-assembly is a process in which energy-consuming chemical reaction networks drive the assembly of molecules. Prominent examples from biology include the GTP-fueled microtubule and ATP-driven actin assembly. Pattern formation and oscillatory behavior are some of the unique properties of the emerging assemblies.

Self-selection of dissipative assemblies driven by primitive chemical reaction networks.

Life is a dissipative nonequilibrium structure that requires constant consumption of energy to sustain itself. How such an unstable state could have selected from an abiotic pool of molecules remains a mystery. Here we show that liquid phase-separation offers a mechanism for the selection of dissipative products from a library of reacting molecules.

Chemogenomic Profiling of Human and Microbial FK506-Binding Proteins.

FK506-binding proteins (FKBPs) are evolutionarily conserved proteins that display peptidyl-prolyl isomerase activities and act as coreceptors for immunosuppressants. Microbial macrophage-infectivity-potentiator (Mip)-type FKBPs can enhance infectivity. However, developing druglike ligands for FKBPs or Mips has proven difficult, and many FKBPs and Mips still lack biologically useful ligands.

Non-equilibrium dissipative supramolecular materials with a tunable lifetime.

Many biological materials exist in non-equilibrium states driven by the irreversible consumption of high-energy molecules like ATP or GTP. These energy-dissipating structures are governed by kinetics and are thus endowed with unique properties including spatiotemporal control over their presence. Here we show man-made equivalents of materials driven by the consumption of high-energy molecules and explore their unique properties.
