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.

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

Inverted positioning of dnmt1 inhibitor in the active site of dnmt1 caused by hydrophobicity/hydrophilicity of the terminal structure

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.

Modular Medical Imaging Agents Based on Azide–Alkyne Huisgen Cycloadditions: Synthesis and Pre-Clinical Evaluation of 18F-Labeled PSMA-Tracers for Prostate Cancer Imaging

Since the seminal contribution of Rolf Huisgen to develop the [3+2] cycloaddition of 1,3-dipolar compounds, its azide–alkyne variant has established itself as the key step in numerous organic syntheses and bioorthogonal processes in materials science and chemical biology. In the present study, the copper(I)-catalyzed azide–alkyne cycloaddition was applied for the development of a modular molecular platform for medical imaging of the prostate-specific membrane antigen (PSMA), using positron emission tomography. This process is shown from molecular design, through synthesis automation and in vitro studies, all the way to pre-clinical in vivo evaluation of fluorine-18- labeled PSMA-targeting ‘F-PSMA-MIC’ radiotracers (t1/2=109.7 min). Pre-clinical data indicate that the modular PSMA-scaffold has similar binding affinity and imaging properties to the clinically used [68Ga]PSMA-11. Furthermore, we demonstrated that targeting the arene-binding in PSMA, facilitated through the [3+2]cycloaddition, can improve binding affinity, which was rationalized by molecular modeling. The here presented PSMA-binding scaffold potentially facilitates easy coupling to other medical imaging moieties, enabling future developments of new modular imaging agents.
