DNA-templated functional group transformations enable sequence-programmed synthesis using small-molecule reagents

DNA-templated organic synthesis (DTS) has previously been used primarily to direct coupling reactions between two DNA-linked reactants. In some cases, reactants are difficult or impossible to tether to DNA oligonucleotides. The development of strategies t

Engineering of carbon based nanomaterials by ring-opening reactions of a reactive azlactone graphene platform

A reactive azlactone-based graphene nanoplatform was successfully synthesized by the ligation of azido-azlactone with alkyne-terminated graphene via Cu(i)-catalyzed cycloaddition. The reactive azlactone rings, grafted on graphene sheets, were subjected to highly efficient ring-opening reactions with functionalized primary amine derivatives incorporating an aminosilane coupling agent or a biological fragment.

Lanthanide directed self-assembly of highly luminescent supramolecular "peptide" bundles from α-amino acid functionalized 2,6-bis(1,2,3-triazol-4-yl)pyridine (btp) ligands

Ligands containing the [2,6-bis(1,2,3-triazol-4-yl)pyridine] (btp) motif have recently shown promise in coordination chemistry. The motif is synthesized via the Cu(I)-catalyzed "click" reaction and can be conveniently functionalized when compared to other

Hybrid Nanomedicine Fabricated from Photosensitizer-Terminated Metal–Organic Framework Nanoparticles for Photodynamic Therapy and Hypoxia-Activated Cascade Chemotherapy

During photodynamic therapy (PDT), severe hypoxia often occurs as an undesirable limitation of PDT owing to the O2-consuming photodynamic process, compromising the effectiveness of PDT. To overcome this problem, several strategies aiming to improve tumor oxygenation are developed. Unlike these traditional approaches, an opposite method combining hypoxia-activated prodrug and PDT may provide a promising strategy for cancer synergistic therapy. In light of this, azido-/photosensitizer-terminated UiO-66 nanoscale metal–organic frameworks (UiO-66-H/N3 NMOFs) which serve as nanocarriers for the bioreductive prodrug banoxantrone (AQ4N) are engineered. Owing to the effective shielding of the nanoparticles, the stability of AQ4N is well preserved, highlighting the vital function of the nanocarriers. By virtue of strain-promoted azide–alkyne cycloaddition, the nanocarriers are further decorated with a dense PEG layer to enhance their dispersion in the physiological environment and improve their therapeutic performance. Both in vitro and in vivo studies reveal that the O2-depleting PDT process indeed aggravates intracellular/tumor hypoxia that activates the cytotoxicity of AQ4N through a cascade process, consequently achieving PDT-induced and hypoxia-activated synergistic therapy. Benefiting from the localized therapeutic effect of PDT and hypoxia-activated cytotoxicity of AQ4N, this hybrid nanomedicine exhibits enhanced therapeutic efficacy with negligible systemic toxicity, making it a promising candidate for cancer therapy.

Dipolar HCP materials as alternatives to DMF solvent for azide-based synthesis

Hypercrosslinked polymers HCP-DMF and HCP-DMF-SO3H containing abundant and flexible DMF moieties were designed and synthesized. Benefitting from the solvation microenvironment provided by the pseudo-DMF moities, the polar HCPs manifested outstanding performances in the conversions of NaN3 to benzylic azides and 1,2,3-triazoles in EtOH (95%), respectively, avoiding the use of risky DMF and improving the separation processes of the products.

Thymol as an Interesting Building Block for Promising Fungicides against Fusarium solani

The semisynthesis of 15 new thymol derivatives was achieved through Williamson synthesis and copper-catalyzed azide-alkyne cycloaddition (CuAAC) approaches. The reaction of CuAAC using the "Click Chemistry"strategy, in the presence of an alkynyl thymol de

Discovery of triazolyl thalidomide derivatives as anti-fibrosis agents

Fibrosis with excessive accumulation of extracellular matrix (ECM) often causes progressive organ dysfunction and results in many inflammatory and metabolic diseases, including systemic sclerosis, pulmonary fibrosis, advanced liver disease and advanced kidney disease. The store-operated calcium entry (SOCE) pathway and the related signaling pathway were both found to be the important routes for fibrogenesis. Our aim in this study was to discover novel compounds to inhibit fibrogenesis. A number of triazolyl thalidomide derivatives were synthesized and evaluated for their anti-fibrosis activities. Compounds 7b-e, 8c-d, 10a-b and 10e inhibited intracellular Ca2+ activation and showed no cytotoxicity. Among them, 6-{4-[(3-(1,3-dioxoisoindolin-2-yl)-2,6-dioxopiperidin-1-yl)methyl]-1H-1,2,3-triazol-1-yl}hexanoic acid (10e) with the most potent inhibitory effect was chosen for further examination. The results revealed that compound 10e, a SOCE inhibitor, reversed the migratory ability of TGF-β1-induced myofibroblasts, dedifferentiated myofibroblasts to fibroblasts due to cytoskeleton remodeling, and restrained myofibroblast activation by targeting Orai1 and TGF-β1/SMAD2/3 signaling pathways. The in silico study indicated that compound 10e, with the appropriate lipophilic carbon chain and carboxylic acid, showed a good drug-likeness model score. Conclusively, the SOCE inhibitor, compound 10e, is used as a promising lead compound for the development of a new treatment for fibrosis. This journal is

Chemical Targeting of Voltage Sensitive Dyes to Specific Cells and Molecules in the Brain

Voltage sensitive fluorescent dyes (VSDs) are important tools for probing signal transduction in neurons and other excitable cells. The impact of these highly lipophilic sensors has, however, been limited due to the lack of cell-specific targeting methods in brain tissue or living animals. We address this key challenge by introducing a nongenetic molecular platform for cell- and molecule-specific targeting of synthetic VSDs in the brain. We employ a dextran polymer particle to overcome the inherent lipophilicity of VSDs by dynamic encapsulation and high-affinity ligands to target the construct to specific neuronal cells utilizing only native components of the neurotransmission machinery at physiological expression levels. Dichloropane, a monoamine transporter ligand, enables targeting of dense dopaminergic axons in the mouse striatum and sparse noradrenergic axons in the mouse cortex in acute brain slices. PFQX in conjunction with ligand-directed acyl imidazole chemistry enables covalent labeling of AMPA-type glutamate receptors in the same brain regions. Probe variants bearing either a classical electrochromic ANEP dye or state-of-the-art VoltageFluor-type dye respond to membrane potential changes in a similar manner to the parent dyes, as shown by whole-cell patch recording. We demonstrate the feasibility of optical voltage recording with our probes in brain tissue with one-photon and two-photon fluorescence microscopy and define the signal limits of optical voltage imaging with synthetic sensors under a low photon budget determined by the native expression levels of the target proteins. This work demonstrates the feasibility of a chemical targeting approach and expands the possibilities of cell-specific imaging and pharmacology.

Spherical Supramolecular Structures Constructed via Chemically Symmetric Perylene Bisimides: Beyond Columnar Assembly

Like other discotic molecules, self-assembled supramolecular structures of perylene bisimides (PBIs) are commonly limited to columnar or lamellar structures due to their distinct π-conjugated scaffolds and unique rectangular shape of perylene cores. The discovery of PBIs with supramolecular structures beyond layers and columns may expand the scope of PBI-based materials. A series of unconventional spherical packing phases in PBIs, including A15 phase, σ phase, dodecagonal quasicrystalline (DQC) phase, and body-centered cubic (BCC) phase, is reported. A strategy involving functionalization of perylene core with several polyhedral oligomeric silsesquioxane (POSS) cages achieved spherical assemblies of PBIs, instead of columnar assemblies, due to the significantly increased steric hindrance at the periphery. This strategy may also be employed for the discovery of unconventional spherical assemblies in other related discotic molecules by the introduction of similar bulky functional groups at their periphery. An unusual inverse phase transition sequence from a BCC phase to a σ phase was observed by increasing annealing temperature.
