Ren, Jing-Ling published the artcileLimonoids containing a C₁-O-C₂₉ moiety: isolation, structural modification, and antiviral activity, Quality Control of 6313-54-8, the publication is Marine Drugs (2018), 16(11), 434, database is CAplus and MEDLINE.

Five new limonoids named thaigranatins A-E (1-5), containing a C1-O-C29 moiety, were isolated from seeds of the Thai Xylocarpus granatum, collected at the mangrove swamp of Trang Province, together with the known limonoid, granatumin L (6). The structures of these compounds were established by HR-ESIMS and extensive NMR spectroscopic data. The absolute configuration of 1 was unequivocally determined by single-crystal X-ray diffraction anal., conducted with Cu Kα radiation; whereas that of 2 or 6 was established to be the same as that of 1 by the similarity of their electronic CD (ECD) spectra. In view of the marked antiviral activity of 6, its structure was modified via hydrolysis with alk. KOH, esterification with diazomethane and various organic acids, and oximization with hydroxyamine. Finally, 18 derivatives, viz. 7-10, 8a-8i, 9a-9b, and 10a-10c, were obtained. In vitro antiviral activities of these derivatives against human immunodeficiency virus 1 (HIV-1) and influenza A virus (IAV) were evaluated. Most notably, 8i exhibited marked inhibitory activity against HIV-1 with an IC50 value of 15.98 ± 6.87 μM and a CC50 value greater than 100.0 μM; whereas 10b showed significant inhibitory activity against IAV with an IC50 value of 14.02 ± 3.54 μM and a CC50 value greater than 100.0 μM.

A unified strategy was conceived and implemented to deliver conformationally constrained anilides based on their preferred cis-amide conformers. The imidazole/triazole mimicing amide bonds were designed, building upon an earlier discovery of a novel series of tricyclic lactams MK2 kinase inhibitors. This approach enabled rapid, modular synthesis of structurally novel analogs. The efficient SAR development led to the discovery of low mol. weight and potent MK2 non-ATP competitive inhibitors with good ligand efficiency, which led to improved permeability and oral exposure in rats.

A photoredox/nickel dual catalyzed reductive hydrobenzylation of alkynes and benzyl chlorides by employing alkyl amines as a stoichiometric reductant is described. This synergistic protocol proceeds via Markovnikov-selective migratory insertion of an alkyne into nickel hydride, followed by cross-coupling with benzyl chloride, providing facile access to important 1,1-disubstituted olefins. This reaction enables the generation of nickel hydride by utilizing readily available alkyl amines as the hydrogen source. The mild conditions are compatible with a wide range of aryl and alkyl alkynes as well as chlorides.
