Published: January 2019

Stimuli-responsive biomaterials are useful platforms for environmentally triggered drug delivery. By varying the molecular architecture of orthogonal stimuli-labile linkages between small molecules and non-degradable materials, we demonstrate the Boolean logic-based release of model therapeutics from gels. Programmable responses are demonstrated for materials sensitive to input combinations involving enzymes, chemical reductants, and light via YES, OR, and AND logic gates.

Targeted protein degradation (TPD) offers a promising approach for chemical probe and drug discovery that uses small molecules or biologics to direct proteins to the cellular machinery for destruction. Among the >600 human E3 ligases, CRBN and VHL have served as workhorses for ubiquitin-proteasome system-dependent TPD. Identification of additional E3 ligases capable of supporting TPD would unlock the full potential of this mechanism for both research and pharmaceutical applications.

Flow chemistry-enabled asymmetric synthesis of cyproterone acetate in a chemo-biocatalytic approach.

Engineering Center of Catalysis and Synthesis for Chiral Molecules, Department of Chemistry, Fudan University, Shanghai, 200433, China.

Flow chemistry has many advantages over batch synthesis of organic small-molecules in terms of environmental compatibility, safety and synthetic efficiency when scale-up is considered. Herein, we report the 10-step chemo-biocatalytic continuous flow asymmetric synthesis of cyproterone acetate (4) in which 10 transformations are combined into a telescoped flow linear sequence from commercially available 4-androstene-3, 17-dione (11). This integrated one-flow synthesis features an engineered 3-ketosteroid-Δ-dehydrogenase (ReM2)-catalyzed Δ-dehydrogenation to form the C1, C2-double bond of A ring, a substrate-controlled Co-catalyzed Mukaiyama hydration of 9 to forge the crucial chiral C17α-OH group of D ring with excellent stereoselectivity, and a rapid flow Corey-Chaykovsky cyclopropanation of 7 to build the cyclopropyl core of A ring.

Multi-Resonance 1,4-BN-Heteroarene for Filterless Narrowband Photodetector.

Angew Chem Int Ed Engl

January 2025

Nankai University, College of Chemistry, Weijin Road 94, 300071, Tianjin, CHINA.

As an emerging class of optoelectronic materials, multi-resonance (MR) 1,4-BN-heteroarenes have been extensively employed as narrowband electroluminescence materials, whereas their absorption feature has largely been neglected. Here we construct the first MR-molecule-based phototransistor for filterless narrowband photodetectors (NBPDs) by anchoring narrowband absorption MR molecules on the high-mobility semiconductor indium-zinc-oxide (IZO) film. The resulting device exhibits high-performance photodetection with a small full-width at half-maximum (FWHM) of 33 nm, which represents a new record for NBPDs based on intrinsic narrowband absorbing materials.

Aptazyme-directed A-to-I RNA editing.

Methods Enzymol

January 2025

Natural Products Research Center, Chengdu Institute of Biology, Chinese Academy of Science, Chengdu, P.R. China. Electronic address:

As a promising therapeutic approach, the RNA editing process can correct pathogenic mutations and is reversible and tunable, without permanently altering the genome. RNA editing mediated by human ADAR proteins offers unique advantages, including high specificity and low immunogenicity. Compared to CRISPR-based gene editing techniques, RNA editing events are temporary, which can reduce the risk of long-term unintended side effects, making off-target edits less concerning than DNA-targeting methods.
