Lokhov, R. E. published the artcile< Kinetics of N-oxidation of compounds of the quinoline series and isomeric benzoquinolines by perbenzoic acid in chloroform and aqueous dioxane>, Recommanded Product: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is oxidation quinoline benzoquinoline peroxybenzoic acid.

Rate constants and activation parameters were determined for the title reactions; a bimol. mechanism was indicated. Annelation of pyridine lowered its oxidation rate. The rate constant for oxidation of 4-amino-2,3-benzoquinoline was nearly an order of magnitude higher in CHCl3 than in aqueous dioxane. Correlations with nucleophilicity parameters and half-wave potentials for the reduction of the azine cations were discussed. The electron d. at N had a small effect; π conjugation between the substituent and the reaction center was an important factor.

Amey, Ronald L.; Martin, J. C. published the artcile< Synthesis and reactions of stable alkoxyaryltrifluoroperiodinanes. A ""tamed"" analog of iodine pentafluoride for use in oxidations of amines, alcohols, and other species>, Synthetic Route of 112-63-0, the main research area is iodinane per alkoxyaryl trifluoro; periodinane alkoxyaryl trifluoro; oxidation periodinane alc amine; iodine pentafluoride analog; benziodoxole preparation reaction.

Stable alkoxyaryltrifluoroperiodinanes I and II were prepared by oxidation of the resp. parent iodo alcs. 5,2-MeIC6H3C(CF3)2OH and 2-IC6H4CMe2OH with excess CF3OF. The stability and low reactivity of I and II are ascribed to the strong stabilizing influence of the 5-membered ring. The reaction of I with Me3SiCl gives the corresponding iodine(III) species, III, and chlorine. I is hydrolyzed with aqueous base to give a species thought to be iodinane oxide (IV). I is a selective reagent for the oxidation of primary and secondary amines or alcs. bearing α hydrogens to the corresponding aldehyde or ketone. In contrast to iodine pentafluoride, I does not further oxidize the product aldehydes to acids. tert-Butylamine is oxidized by I to give 1,1,1′,1′-tetramethylazoethane. PhMgBr reacts with I to give PhF. Possible mechanisms for these selective oxidations are discussed. It is suggested that the stabilizing structural features of I make it a tamed analog of IF5.

Schoene, Jens; Gazzi, Thais; Lindemann, Peter; Christmann, Mathias; Volkamer, Andrea; Nazare, Marc published the artcile< Probing 2H-Indazoles as Templates for SGK1, Tie2, and SRC Kinase Inhibitors>, Computed Properties of 112-63-0, the main research area is nitrogen heterocycle indazole synthesis SGK1 Tie2 SRC kinase; docking; drug design; focused library; kinase inhibition; nitrogen heterocycles; scaffolds.

The broader and systematic application of a novel scaffold is often hampered by the unavailability of a short and reliable synthetic access. We investigated a new strategy for the design and synthesis of an array of N2-substituted aza-2H-indazole derivatives as potential kinase inhibitors. Guided by a rational ligand alignment approach to qualify the so-far underrepresented aza-2H-indazole scaffold, indazoles were connected at the N2 position with a Ph spacer and an arylsulfonamide or amide linkage. Initial profiling against a panel of 30 kinases confirmed the in silico predicted selectivity bias. A synthesized focused library of 52 different aza-2H-indazole derivatives showed good initial selective inhibition against SGK1, Tie2, and SRC kinases, with the best representatives having IC50 values in the range of 500 nM. In a comparative computational study, these data were analyzed and rationalized in light of docking studies.

Schleicher, Kristin D.; Jamison, Timothy F. published the artcile< A reductive coupling strategy towards ripostatin A>, COA of Formula: C6H10O5, the main research area is ripostatin A synthesis reductive coupling enyne epoxide; catalysis; natural product; nickel; reductive coupling; ripostatin A; synthesis.

Synthetic studies on the antibiotic natural product ripostatin A have been carried out with the aim to construct the C9-C10 bond by a nickel(0)-catalyzed coupling reaction of an enyne and an epoxide, followed by rearrangement of the resulting dienylcyclopropane intermediate to afford the skipped 1,4,7-triene. A cyclopropyl enyne fragment, I, corresponding to C1-C9 has been synthesized in high yield and demonstrated to be a competent substrate for the nickel(0)-catalyzed coupling with a model epoxide. Several synthetic approaches toward the C10-C26 epoxide have been pursued. The C13 stereocenter can be set by allylation and reductive decyanation of a cyanohydrin acetonide. A mild, fluoride-promoted decarboxylation enables construction of the C15-C16 bond by an aldol reaction. The product of this transformation, ketone II, is of the correct oxidation state and potentially three steps removed from the targeted epoxide fragment.

Temozolomide (TMZ), an oral alkylating agent, is the widely used first-line chemotherapeutic reagent for glioma in clinical practice. However, TMZ-induced autophagy is another cellular process favoring glioma cell survival. This study aimed to explore whether hispidulin can facilitate TMZ-induced cell death of glioma. The MTT assay showed that coadministration with hispidulin and TMZ could significantly decrease the viability of glioma U87MG cells. Meanwhile, hispidulin administration was also observed to promote TMZ-induced apoptosis. Furthermore, additional hispidulin treatment further elevated TMZ-induced expression of Bax, cleaved-caspase-9, and cleaved-caspase-3 protein but decreased Bcl-2 protein expression in U87MG cells. We also observed that hispidulin suppressed TMZ-induced autophagy to promote apoptosis, as showed by decreased AVOs and LC3B-I/II protein expression. These results collectively suggested that the combination of hispidulin and TMZ could improve the antitumor efficiency of TMZ against malignant gliomas.

Zhao, Xin; Cui, Lijuan; Zhang, Yushan; Guo, Chao; Deng, Lijiao; Wen, Zhitong; Lu, Zhihong; Shi, Xiaoyuan; Xing, Haojie; Liu, Yunfeng; Zhang, Yi published the artcile< Screening for potential therapeutic agents for non-small cell lung cancer by targeting ferroptosis>, COA of Formula: C15H22N2O2, the main research area is NSCLC ferroptosis therapeutic agent screening target.

Ferroptosis is a form of non-apoptotic and iron-dependent cell death originally identified in cancer cells. Recently, emerging evidence showed that ferroptosis-targeting therapy could be a novel promising anti-tumor treatment. However, systematic analyses of ferroptosis-related genes for the prognosis of non-small cell lung cancer (NSCLC) and the development of antitumor drugs exploiting the ferroptosis process remain rare. This study aimed to identify genes related to ferroptosis and NSCLC and to initially screen lead compounds that induce ferroptosis in tumor cells. We downloaded mRNA expression profiles and NSCLC clin. data from The Cancer Genome Atlas database to explore the prognostic role of ferroptosis-related genes. Four prognosis-associated ferroptosis-related genes were screened using univariate Cox regression anal. and the lasso Cox regression anal., which could divide patients with NSCLC into high- and low-risk groups. Then, based on differentially expressed risk- and ferroptosis-related genes, the neg. correlated lead compound flufenamic acid (FFA) was screened through the Connective Map database. This project confirmed that FFA induced ferroptosis in A549 cells and inhibited growth and migration in a dose-dependent manner through CCK-8, scratch, and immunofluorescence assays. In conclusion, targeting ferroptosis might be a therapeutic alternative for NSCLC.

The title compound, C17H13NO3, adopts a Z configuration about the C=C bond. The isoxazole and methoxybenzylidene rings are almost coplanar with a dihedral angle of 9.63 (7)° between them. In contrast, the Ph substituent is twisted significantly out of the plane of the oxazole ring, with the two rings inclined to each other by 46.22 (4)°. The crystal structure features C-H···O, C-H···N and C-H···π hydrogen bonds and π-π contacts. An anal. of the Hirshfeld surfaces points to the importance of H···H, H···C/C···H and H···O/O···H contacts. The included surface areas of the title compound were compared to those of the isomeric structure (Z)-4-(4-methoxybenzylidene)-3-phenylisoxazol-5(4H)-one [Zhang et al. (2015).

Yang, Xinwei; Li, Xiao; Zhu, Yanbo; Gao, YingYing; Xu, Liping published the artcile< Paeoniflorin upregulates mitochondrial thioredoxin of Schwann cells to improve diabetic peripheral neuropathy indicated by 4D label-free quantitative proteomics>, Application of C19H34O2, the main research area is .

Diabetic peripheral neuropathy (DPN) is a diabetic complication characterized by demyelination. The pathogenesis of DPN has not been fully elucidated, thus lacking therapies. In the current study, we aimed to confirm whether paeoniflorin (PF) could improve DPN by upregulating mitochondrial thioredoxin (Trx2) based on 4D Label-free proteomic experiments of Schwann cells (SCs) mitochondria. Firstly, PF increased the expression of mitochondrial processing peptidase α (Pmpca) and small ubiquitin-related modifier 1 (Sumo1) to increase mitochondrial protein processing of Trx2. Then, PF increased the protein expression of Trx reductase 2 (TrxR2) and peroxiredoxin 3 (Prx3), which belong to mitochondrial Trx systems. Accordingly, PF decreased mitochondrial reactive oxygen species (ROS) while increasing mtDNA and mitochondrial membrane potential to improve mitochondria function under high glucose environment. Furthermore, total glucosides of paeony capsules (TGP), containing more than 90% PF, increased the Trx2, TrxR2, and Prx3 levels in sciatic nerve of DPN rats, thus reducing demyelination as well as improving mech. pain threshold, thermal pain threshold, motor nerve conduction velocity (MNCV), and sensor nerve conduction velocity (SNCV). Overall, these results suggest that PF could provide protection for DPN by upregulating Trx2.
