Gu, Yu-lei published the artcileGene knockout or inhibition of macrophage migration inhibitory factor alleviates lipopolysaccharide-induced liver injury via inhibiting inflammatory response, Application of 4-Iodo-6-phenylpyrimidine, the publication is Hepatobiliary & Pancreatic Diseases International (2021), 20(5), 469-477, database is CAplus and MEDLINE.

Background: Liver injury is one of the most common complications during sepsis. Macrophage migration inhibitory factor (MIF) is an important proinflammatory cytokine. This study explored the role of MIF in the lipopolysaccharide (LPS)-induced liver injury through genetically manipulated mouse strains. Methods: The model of LPS-induced liver injury was established in wild-type and Mif-knockout C57/BL6 mice. Serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin (TBil) were detected, and the expressions of MIF, tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) were measured. Liver histopathol. was conducted to assess liver injury. Moreover, the inhibitions of MIF with (S, R)-3-(4-hydroxyphenyl)-4, 5-dihydro-5-isoxazole acetic acid Me ester (ISO-1) and 4-iodo-6-phenylpyrimidine (4-IPP) were used to evaluate their therapeutic potential of liver injury. Results: Compared with wild-type mice, the liver function indexes and inflammation factors presented no significant difference in the Mif^-/- mice. After 72 h of the LPS-induced liver injury, serum levels of ALT, AST, and TBil as well as TNF-α and IL-1β were significantly increased, but the knockout of Mif attenuated liver injury and inflammatory response. In liver tissue, m RNA levels of TNF-α, IL-1β and NF-κB p65 were remarkably elevated in LPS-induced liver injury, while the knockout of Mif reduced these levels. Moreover, in LPS-induced liver injury, the inhibitions of MIF with ISO-1 and 4-IPP alleviated liver injury and slightly attenuated inflammatory response. Importantly, compared to mice with LPS-induced liver injury, Mif knockout or MIF inhibitions significantly prolonged the survival of the mice. Conclusions: In LPS-induced liver injury, the knockout of Mif or MIF inhibitions alleviated liver injury and slightly attenuated inflammatory response, thereby prolonged the survival of the mice. Targeting MIF may be an important strategy to protect the liver from injury during sepsis.

Lu, Xi published the artcilePractical carbon-carbon bond formation from olefins through nickel-catalyzed reductive olefin hydrocarbonation, HPLC of Formula: 161370-66-7, the publication is Nature Communications (2016), 11129pp., database is CAplus and MEDLINE.

A general process for the intermol. reductive coupling of unactivated olefins with alkyl or aryl electrophiles under the promotion of a simple nickel catalyst system was reported. This new reaction presented a conceptually unique and practical strategy for the construction of C(sp²)-C(sp³) and C(sp³)-C(sp³) bonds without using any organometallic reagent. The reductive olefin hydrocarbonation also exhibited excellent compatibility with varieties of synthetically important functional groups and therefore, provided a straightforward approach for modification of complex organic mols. containing olefin groups.

This paper discloses a transition metal-free selective C-H dithiocarbamation of drug skeletons using disulfiram (DSF) in the presence of KI/K₂S₂O₈ in DMF/H₂O. Drug skeletons, including 5-aminopyrazoles, indoles, pyrroloquinoline, and Julolidine, underwent C-H dithiocarbamation smoothly to afford a variety of drug-like mols. in moderate to good yields. It was found that the in situ formed 5-aminopyrazole iodide is the key intermediate for the dithiocarbamation. Bioassay results show that some of these N-heterocyclic dithiocarbamate derivatives exhibit good antifungal activity against Colletotrichum gloeosprioides and Fusarium oxysporum, F. proliferatum, Fusarium solani, Geotrichum candidum, Penicillium digitatum, Penicillium italicum, Pyricularia grisea.

Han, Jie published the artcileSynthesis, liquid crystalline and photoluminescent properties of 1,3,4-oxadiazole derivatives: From calamitic monomers, H-Shaped dimers to calix[4]arene-based tetramers, Quality Control of 39115-95-2, the publication is Dyes and Pigments (2018), 234-241, database is CAplus.

A new class of calamitic 1,3,4-oxadiazole monomers H-shaped dimers , and calix [4]arene-based tetramer have been synthesized and characterized fully by means of ¹H NMR (proton NMR), ¹³C-NMR, high resolution mass spectroscopy (HRMS) and elemental anal., and the thermal properties and photoluminescent behaviors have been investigated systemically. All of the monomers display stable liquid crystalline properties with smectic and/or nematic mesophases determined by the electronic and steric nature of the terminal groups. In contrast, both the H-shaped dimers and the calix [4]arene based tetramer are not mesogenic, while they show specific recognition for Cu²⁺ through the fluorescent emission intensity quenching. The relationship between the mol. structures and properties has been discussed according to the mol. shapes.

Wu, Fu-Peng published the artcileCopper-Catalyzed Borylative Methylation of Alkyl Iodides with CO as the C1 Source: Advantaged by Faster Reaction of CuH over CuBpin, Application In Synthesis of 638-45-9, the publication is Angewandte Chemie, International Edition (2021), 60(21), 11730-11734, database is CAplus and MEDLINE.

CuH and CuBpin are versatile catalysts and intermediates in organic chem. However, studies that involve both CuH and CuBpin in the same reaction is still rarely reported due to their high reactivity. Now, a study on CuH- and CuBpin-catalyzed borylative methylation of alkyl iodides with CO as the C1 source is reported. Various one carbon prolongated alkyl boranes (RCH₂Bpin and RCH(Bpin)₂) were produced in moderate to good yields from the corresponding alkyl iodides (RI). In this cooperative system, CuH reacts with alkyl iodide faster than CuBpin.

Yu, Tao published the artcileDiscovery of dimethyl pent-4-ynoic acid derivatives, as potent and orally bioavailable DGAT1 inhibitors that suppress body weight in diet-induced mouse obesity model, Category: iodides-buliding-blocks, the publication is Bioorganic & Medicinal Chemistry Letters (2018), 28(10), 1686-1692, database is CAplus and MEDLINE.

Diacylglycerol acetyltransferase (DGAT) is expressed abundantly in intestine, liver, and adipose tissues. DGAT1 is the crucial and rate-limiting enzyme that mediates the final step in triacylglycerol (TAG) resynthesis during dietary fat absorption. However, too much triacylglycerol (TAG) reserve will lead to genetic obesity (Hubert et al., 2000). DGAT1 knockout mice could survive and displayed a reduction in the postprandial rise of plasma TG, and increased sensitivity of insulin and leptin. Here the authors report the discovery and characterization of a novel selective DGAT1 inhibitor 29 (5-(4-(4-amino-5-oxo-7,8-dihydropyrimido[5,4f][1,4] oxazepin-6(5H)-yl)-2,6-dimethylphenyl)-3,3-dimethylpent-4-ynoic acid) to potentially treat obesity. Compound 29 showed lipid lowering effect in mouse lipid tolerance test (LTT) and also reduced body weight in DIO mice without observable liver damage.

Guo, Yongxian published the artcileForce-Induced Molecular Isomerization for the Construction of Multicolor Luminescent Segmented Molecular Crystals, Related Products of iodides-buliding-blocks, the publication is Advanced Optical Materials (2022), 10(2), 2101794, database is CAplus.

Multicolor luminescent segmented materials have attracted tremendous research interest due to their potential applications as barcoding materials in information security and anti-counterfeiting. Although much effort has been devoted to the preparation of photonic barcodes based on different light-emitting materials, the rational design of barcoding materials with well-controlled emission color and length at desired position remains a challenge. Here, a novel strategy to fabricate multicolor luminescent segmented 1D mol. crystals is reported by manipulating the mol. conformation and intermol. interactions of the mechanochromic crystals, which are assembled from a rationally designed twisting conjugated mol. The emission color of these mechanochromic crystals changes from green to orange with the mechanism of synergy effect of force-induced mol. isomerization from trans to cis state and mol. packing changes from cross to parallel, which is revealed by single crystal X-ray diffraction. Multicolor luminescent segmented 1D microribbons are fabricated by applying precisely controlled forces by tapping mode at. force microscope, which shows the encoding capability. These findings provide a new method that allows the controllable fabrication of segmented materials with tunable emission color and length at desired position toward barcoding applications.
