The alpha-methyl chalcone SD400 is a potent inhibitor of tubulin assembly and possesses potent anticancer activity. Various chalcone analogues were synthesized and evaluated for their cell growth inhibitory properties against the K562 human chronic myelogenous leukemia cell line (SD400, IC50 0.21 nM; combretastatin A4 CA4, IC50 2.0 nM). Cell cycle analysis by flow cytometry indicated that these agents are antimitotic (SD400, 83% of the cells are in G2/M phase; CA4 90%). They inhibit tubulin assembly at low concentration (SD400, IC50 0.46 muM; CA4, 0.10 muM) and compete with [3H]colchicine for binding to tubulin (8% [3H]colchicine remained bound to tubulin after competition with SD400 or CA4). Upon treatment with SD400, remarkable cell shape changes were elicited in HUVEC cells, consistent with vasculature damaging activity.

The appropriate choice of redox mediator can avoid electrode passivation and overpotential, which strongly inhibit the efficient activation of substrates in electrolysis. 2879-20-1, Name is 1-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)ethanone,introducing its new discovery.

A green atom-economical method for the synthesis of highly functionalized 1-amino and 1-carbon substituted isoquinolines from the reaction of N?-hydroxybenzimidamides and aryl ketoximes, respectively, with alkynes via pentamethylcyclopentadienylcobalt(III)-catalyzed C – H/N – O bond activation is described. The external oxidant-free annulation reaction uses the =NOH moiety in N?-hydroxybenzimidamides or N-aromatic ketone oximes as the directing group and internal oxidant. This first row transition metal-catalyzed annulation serves as an efficient alternative for the synthesis of isoquinolines, as water is the only by-product and expensive noble metals such as rhodium(III), iridium(III), palladium(II), and ruthenium(II) are not required. The reaction proceeds via C – H activation, alkyne insertion, reductive elimination, and N – O activation.

The growing field of applications of O-alkyl hydroxylamines in medicinal chemistry and chemical biology has motivated the search for a parallel synthesis. A solid-phase approach based on the alkylation by alcohols of a new supported N-hydroxyphthalimide reagent using a Mitsunobu reaction followed by methylaminolysis has been optimized. This study points out the importance of the linker and a specific base effect for the Mitsunobu reaction. A large variety of alcohols can be used to give with moderate to high yields diverse O-alkyl hydroxylamines in high purity.

The hydrofunctionalization of alkenes, explored for over 100 years, offers the potential for a direct, atom-economical approach to value-added products. While thermodynamically favored, the kinetic barrier to such processes necessitates the use of catalysts to control selectivity and reactivity. Modern variants typically rely on noble metals that require different ligands for each class of hydrofunctionalization, thereby limiting generality. This Letter describes a general iron-based system that catalyzes the hydroamination and hydroetherification of simple unactivated olefins.

Chemical Research Letters, May 2021. The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. Which mentioned a new discovery about SDS of cas: 2879-20-1, SDS of cas: 2879-20-1

Purpose: To evaluate the antihepatotoxic activity of dihydropyrimidinone derivative linked with 1,4-benzodioxane. Methods: A series of novel dihydropyrimidinone derivatives linked with 1,4-benzodioxane moiety were synthesized in good yield. Modern spectroscopic techniques and elemental analysis were used for the identification of the synthesized compounds. The hepatoprotective properties of compound 2, 4-(4-nitrophenyl)-5-(2,3-dihydro-1,4-benzodioxin-6-ylcarbonyl)-3,4-dihydropyrimidin-2(1H)-one, was evaluated in a carbon tetrachloride (CCl4 )-induced hepatotoxicity rat model. Results: Administration of compound 2 prior to CCl4 exposure produced a dose-dependent decrease in the levels of elevated biochemical parameters compared with the standard drug silymarin. CCl4 induced oxidative stress, increased lipid profile, and decreased high-density lipoprotein (HDL) levels. Compound 2 (20 mg/kg) significantly reduced the lipid profile and significantly improved HDL levels in a dose-dependent manner. CCl4 treatment increased malondialdehyde (MDA) level and decreased nonprotein thiol (NP-SH) and total protein (TP) in liver tissues. Pretreatment of rats with compound 2 (20 mg/kg) decreased MDA level and increased NP-SH and TP in liver tissues. Histopathological examination of liver tissues also confirmed the hepatoprotective activity of compound 2. Conclusion: These results demonstrate the antihepatotoxic activity of compound 2 in CCl4-induced hepatotoxicity model.
