Sakata, Yoko published the artcileMetallonanobelt: A Kinetically Stable Shape-Persistent Molecular Belt Prepared by Reversible Self-Assembly Processes, Computed Properties of 68569-14-2, the publication is Inorganic Chemistry (2018), 57(24), 15500-15506, database is CAplus and MEDLINE.

A triptycene-based shape-persistent belt-shaped macrocycle, metallonanobelt, was synthesized by the self-assembly of 2,3,6,7-tetraaminotriptycene L and square planar Pd²⁺. The pentamer was selectively formed by the complexation of L with Pd²⁺ in the presence of the pillar[6]arene derivative P6 having triethylene glycol pendant as a template, whereas a mixture of a trimer, tetramer, and pentamer was obtained in the absence of the template. The pentamer was successfully isolated based on the solubility difference between the metallonanobelt and the template. Also the isolated pentamer was remarkably stable in solutions such as acetonitrile or methanol thanks to the relatively inert planar chelate metal complex, [Pd(o-phenylenediamine)₂] unit. Thus, the authors can handle the metallonanobelt almost as a static organic nanobelt that was synthesized covalently.

Chan, Kelvin S. L. published the artcileLigand-enabled cross-coupling of C(sp³)-H bonds with arylboron reagents via Pd(II)/Pd(0) catalysis, Safety of Tetrakis(acetonitrile)palladium(II) Ditriflate, the publication is Nature Chemistry (2014), 6(2), 146-150, database is CAplus and MEDLINE.

There have been numerous developments in C-H activation reactions in the past decade. Attracted by the ability to functionalize mols. directly at ostensibly unreactive C-H bonds, chemists have discovered reaction conditions that enable reactions of C(sp²)-H and C(sp³)-H bonds with a variety of coupling partners. Despite these advances, the development of suitable ligands that enable catalytic C(sp³)-H bond functionalization remains a significant challenge. Herein we report the discovery of a mono-N-protected amino acid ligand that enables Pd(II)-catalyzed coupling of γ-C(sp³)-H bonds in triflyl-protected amines with arylboron reagents. Remarkably, no background reaction was observed in the absence of ligand. A variety of amine substrates and arylboron reagents were cross-coupled using this method. Arylation of optically active substrates derived from amino acids also provides a potential route for preparing non-proteinogenic amino acids.

Huang, Yunyuan published the artcileDiscovery of novel allosteric site and covalent inhibitors of FBPase with potent hypoglycemic effects, Related Products of nitriles-buliding-blocks, the publication is European Journal of Medicinal Chemistry (2019), 111749, database is CAplus and MEDLINE.

Fructose-1,6-bisphosphatase (FBPase) is an essential enzyme of GNG pathway. Significant advances demonstrate the FBPase plays a critical role in treatment of diabetes. Numerous FBPase inhibitors were developed by targeting AMP site, nevertheless, none of these inhibitors has exhibited suitable potency and druggability. Herein, a new allosteric site (C128) on FBPase was discovered, and several nitrostyrene compounds exhibiting potent FBPase inhibitions were found covalently bind to C128 site on FBPase. Mutagenesis suggest that C128 is the only cysteine that can influence FBPase inhibition, the N125-S124-S123 pathway was most likely involved in allosteric signaling transmission between C128 and active site. However, these nitrostyrenes may bind with multiple cysteine besides C128 in FBPase. To improve pocket selectivity, a series of novel compounds (14a-14n) were re-designed rationally by integrating fragment-based covalent virtual screening and machine-learning-based synthetic complexity evaluation. As expected, the mass spectrometry validated that the proportion of title compounds binding to the C128 in FBPase was significantly higher than that of nitrostyrenes. Notably, under physiol. and pathol. conditions, the treatment of compounds 14b(I), 14c(II), 14i(III) or 14n(IV) led to potent inhibition of glucose production, as well as decreased triglyceride and total cholesterol levels in mouse primary hepatocytes. We highlight a novel paradigm that mol. targeting C128 site on FBPase can have potent hypoglycemic effect.

Jing, Ke published the artcileVisible-light photoredox-catalyzed carboxylation of benzyl halides with CO₂: Mild and transition-metal-free, Computed Properties of 612-13-5, the publication is Chinese Journal of Catalysis (2022), 43(7), 1667-1673, database is CAplus.

The visible-light photoredox-catalyzed carboxylation of benzyl chlorides and bromides with CO₂ has been reported. With inexpensive organic dyes as photocatalysts and amines as electron donors, this carboxylation proceeds well in the absence of sensitive organometallic reagents, transition metal catalysts, or metallic reductants. A wide range of com. available and inexpensive benzyl halides undergo such carboxylation to give valuable aryl acetic acids, including several pharmaceutical mols. and drug precursors, in moderate to high yields. Moreover, this reaction features mild reaction conditions (one atm. pressure of CO₂ and room temperature), broad substrate scope, good functional group tolerance, easy scalability, and low catalyst loading, thus providing an efficient approach for the assembly of aryl acetic acids.
