Natural products have long served as critical raw materials in chemical and pharmaceutical manufacturing, primarily which can provide superior scaffolds or intermediates for drug discovery development. Over the last century, natural contributed to more than a third of therapeutic production. However, traditional methods producing drugs from become less efficient expensive over past few decades. The combined utilization genome mining synthetic biology based on sequencing, bioinformatics tools, big data analytics, genetic engineering, metabolic systems promises counter this trend. Here, we reviewed recent (2020–2023) examples used resolve challenges production products, such variety, poor efficiency, low yield. Additionally, emerging design principles, building strategies its application prospects NPs synthesis also been discussed.

The recent COVID-19 pandemic underscored the limitations of currently available direct-acting antiviral treatments against acute respiratory RNA-viral infections and stimulated major research initiatives targeting anticoronavirus agents. Two novel nsp5 protease (MPro) inhibitors have been approved, nirmatrelvir ensitrelvir, along with two existing nucleos(t)ide analogues repurposed as nsp12 polymerase inhibitors, remdesivir molnupiravir, but a need still exists for therapies improved potency systemic exposure oral dosing, better metabolic stability, reduced resistance toxicity risks. Herein, we summarize our toward identifying that led to nucleoside 10e 10n, which showed favorable pan-coronavirus activity in cell-infection screens, were metabolized active triphosphate nucleotides cell-incubation studies, demonstrated target (nsp12) engagement biochemical assays.

Comprehensive Summary Dragocins A—C are structurally unique marine natural products featuring an uncommon tri‐oxa‐tricyclic[6.2.1]undecane moiety. However, their extremely low abundance has hindered extensive screening of bioactivities. We hereby describe efficient and modular approach to synthesizing dragocins analogues using commercially available inexpensive anisomycin D‐ribosyl thioglycoside derivative as the starting materials. A key feature our synthesis is construction skeleton. This challenging architecture achieved by stereocontrolled formation β‐ribofuranosidic bond DDQ (2,3‐dichloro‐5,6‐dicyano‐1,4‐benzoquinone)‐promoted intramolecular cross‐dehydrogenative etherification at benzylic position. Our also characterized successful installation a chlorine atom methoxy group tertiary C‐4' position via late‐stage silver‐catalyzed decarboxylative chlorination reaction electrophilic enol intermediate. Cytotoxicity evaluations synthesized compounds revealed demethyl dragocin A, N ‐demethylated potential anticancer candidate due its strong cytotoxicity against A549 lung, HCT116 colorectal MCF7 breast cancer cell lines. work demonstrated preliminary structure‐activity relationship this compound, setting solid foundation for developing novel candidates.

Abstract A visible light‐induced perfluoroalkylative cyclization of 3‐aza‐1,5‐dienes leading to pentasubstituted 1,3‐dihydropyrrole‐2‐ones is presented. The reaction regiospecific, for the radical adds across acrylamido moiety, whereas enaminic double bond functions as a built‐in trap. It could be carried out on 2‐gram scale, and sunlight usable light source. Other virtues protocol include short time, low catalyst loading, mild conditions broad substrate scope.
