Selection Of DNA-Encoded Libraries For Membrane-Permeable Scaffolds

Combinatorial encoded library technologies can provide a set of tools for discovering protein-targeting ligands (molecules) and for drug discovery. These techniques can accelerate ligand discovery by leveraging chemical diversity achievable through genetically encoded combinatorial libraries, for example, by combinatorial permutation of chemical building blocks. Although display technologies such as mRNA and phage display use biological translation machinery to produce peptide-based libraries, hits from these libraries often lack key drug-like properties, for example, cell permeability. This limitation can arise from the peptide backbone's inherent polarity and the tendency to select compounds with polar/charged side chains. Backbone N-methylation can increase scaffold lipophilicity in mRNA display; however, codon table constraints can necessitate longer sequences to fully utilize the available space.DNA-encoded libraries (DELs) offer an alternative approach towards discovering hits against drug targets. However, like other encoded library techniques, DELs face significant obstacles in affinity selections, which tend to enrich library members bearing polar and/or charged moieties, which can have low (poor) passive cell membrane permeability, especially in larger molecular weight libraries, resulting in hits with poor drug-like properties. This selection bias is especially problematic for larger constructs beyond the rule of 5, where fine-tuning lipophilicity can be critical. Furthermore, DNA-encoded libraries can be of low quality. Although algorithmic predictions of lipophilicity exist, these two-dimensional (2D) atomistic calculations cannot capture conformational effects exhibited by larger molecules like peptide macrocycles. Despite over a decade of DEL technology development, no method exists to measure physical properties of encoded molecules across an entire DNA-encoded library. That is, successful translation of hits from encoded library selections can be impeded by low quality libraries and enrichment of highly polar members which tend to have poor passive cell permeability, especially for larger molecular weight libraries.DELs are produced through split-pool synthesis with DNA barcoding to encode the building block of each chemical step. Although this approach can draw on a large number of building blocks and allow for the formation of non-peptidic libraries with a large number of members, synthetic challenges persist. The formation of DELs can be synthetically inefficient. Truncations multiply ( are compounded) throughout synthesis, reducing the representation of properly synthesized constructs. Although strategies to improve library purity, to enable reaction monitoring for macrocycle formation, and to identify problematic chemistry affecting DNA tag amplification may be applied, a direct method for assessing DEL quality on a library-wide basis has yet to be developed.

Rippled Beta-Sheets and Related Materials and Methods

Amyloid-β (Aβ) is a protein that is implicated in Alzheimer’s disease. Aβ oligomers aggregate to form amyloid plaques, which are found in the brains of individuals with Alzheimer’s disease. These plaques have high polydispersity; they vary in shape and size. Previously, researchers at UC Santa Cruz demonstrated that using a racemic mixture of Aβ promoted fibril formation, an aggregation that is less neurotoxic than plaques of high polydispersity. Furthermore, these racemic counterparts form rippled β-sheets.

METHOD FOR DETECTION AND SEPARATION OF ENANTIOMERS USING VESICLE-LIKE NANOSTRUCTURES SELF-ASSEMBLED FROM JANUS NANOPARTICLES

Something that is chiral cannot be superposed over its mirror image, no matter how it is shifted (ex. our hands). These two mirror images, called enantiomers, rotate plane-polarized light in opposite directions.Chiral nanostructures have unique materials properties that can be used in many applications. In pharmaceutical research and development, chiral analysis is critical, as one enantiomer may be more effective than the other. Researchers at UC Santa Cruz have developed new ways of performing enantiomeric analyses using the plasmonic circular dichroism absorption qualities of nanostructures.

Thiazole-Based Covalent Organic Frameworks For Low-Humidity Water Adsorption

The critical challenge of providing clean, potable water in arid and semi-arid regions can be addressed by technologies that efficiently harvest atmospheric water, particularly under low-humidity conditions. UC Berkeley researchers have developed novel thiazole-based Covalent Organic Frameworks (COFs) that serve as highly efficient sorbents for this purpose. These COFs are crystalline, porous materials characterized by high porosity, permanent pore structures, and a chemically tunable nature. The disclosed COFs demonstrate a significant advantage over alternatives by exhibiting a low-humidity water uptake onset, coupled with fast adsorption kinetics, a high water working capacity, and excellent cycling stability. Furthermore, the development includes scalable synthetic methods, such as microwave-assisted and reflux routes, which enable gram-level, practical production.

Chemoenzymatic Synthesis Of Neuroexcitatory And Cuaac-Compatible Kainoid Aalogs

Kainate receptors, also known as kainic acid receptors are ionotropic receptors that bind to and are responsive to glutamate in neurons. These were originally identified as being activated by the compund kainic acid, orignally isolated from algae. Postsynaptic kainate receptors are involved in excitatory neurotransmission while presynaptic kainate receptors are involved in inhibitory neurotransmission. Kainic acid is a potentially very useful compound but very difficult to synthesize. As a result, there are very few pharmacological tool compounds to study kainate receptors and none that are readily tunable to install labeling compounds.
