The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 5-Fluoroindoline(SMILESS: FC1=CC2=C(NCC2)C=C1,cas:2343-22-8) is researched.Quality Control of 1,10-Phenanthroline. The article 《Activation of Nrf2 and Hypoxic Adaptive Response Contribute to Neuroprotection Elicited by Phenylhydroxamic Acid Selective HDAC6 Inhibitors》 in relation to this compound, is published in ACS Chemical Neuroscience. Let’s take a look at the latest research on this compound (cas:2343-22-8).

Activation of HIF-1α and Nrf2 is a primary component of cellular response to oxidative stress, and activation of HIF-1α and Nrf2 provides neuroprotection in models of neurodegenerative disorders, including ischemic stroke, Alzheimer’s and Parkinson’s diseases. Screening a library of CNS-targeted drugs using novel reporters for HIF-1α and Nrf2 elevation in neuronal cells revealed histone deacetylase (HDAC) inhibitors as potential activators of these pathways. We report the identification of phenylhydroxamates as single agents exhibiting tripartite inhibition of HDAC6, inhibition of HIF-1 prolyl hydroxylase (PHD), and activation of Nrf2. Two superior tripartite agents, ING-6 and ING-66, showed neuroprotection against various cellular insults, associated with stabilization of both Nrf2 and HIF-1, and expression of their resp. target genes in vitro and in vivo. Discovery of the innate ability of phenylhydroxamate HDAC inhibitors to activate Nrf2 and HIF provides a novel route to multifunctional neuroprotective agents and cautions against HDAC6 selective inhibitors as chem. probes of specific HDAC isoform function.

This literature about this compound(2343-22-8)Synthetic Route of C8H8FNhas given us a lot of inspiration, and I hope that the research on this compound(5-Fluoroindoline) can be further advanced. Maybe we can get more compounds in a similar way.

Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:2343-22-8) through the article.

The hydroamination of internal alkynes via tandem rhodium catalysis gives branched N-allylic indolines with high regio- and enantioselectivity. An acid switch provides access to the linear isomer in preference to the branched isomer by an isomerization mechanism. Mechanistic studies suggest formation of an allene intermediate, which undergoes hydroamination to generate allylic amines instead of the enamine or imine products typically observed in alkyne hydroaminations.

Author is Bermudez, Jose; Dabbs, Steven; Joiner, Karen A.; King, Frank D..

Indazole I is a potent and selective 5-HT3 receptor antagonist. A novel series of potent 5-HT3 receptor antagonists, 1-indoline- and 1-indolecarboxamides II [R = H , F, Cl, MeO, O2N; R1 = H, Me, Et, Ph; R2 = H, Me; R1R2 = (CH2)2, (CH2)4, (CH2)5; R3 = H, Me; n = 2,3] and III (R1 = H, Me, Et, Ph), resp., is described. The activity of II suggests that aromaticity of the 5-membered ring is not an essential requirement for potency provided that an in plane orientation of the CO group is favored. On the basis of this hypothesis indene IV was prepared In IV the in plane orientation of the CO group is maintained by conjugation with the aromatic ring through the sp2-hybridized C. IV is also a potent 5-HT3 receptor antagonist.

Compound: 5-Fluoroindoline, is researched, Molecular C8H8FN, CAS is 2343-22-8, about Dual-Active-Sites Design of Co@C Catalysts for Ultrahigh Selective Hydrogenation of N-Heteroarenes. Author is Zhang, Sai; Gan, Jie; Xia, Zhaoming; Chen, Xiao; Zou, Yong; Duan, Xuezhi; Qu, Yongquan.

Herein, a general yet powerful strategy to design and fabricate dual-active-sites Co@C core-shell nanoparticle for boosting selective hydrogenation of various N-heteroarenes was reported. It could break the limitation of scaling relation on traditional metal surfaces and thus afford unprecedentedly high selectivity, activity and stability. Combining kinetics anal. and DFT calculations with multiple techniques directly unveil that the critical porous carbon shell with a pore size of 0.53 nm not only allowed H2 diffusion to Co sites for activation and blocked accessibility of N-heteroarenes but also catalyzed hydrogenation of N-heteroarenes via hydrogen spillover from Co sites. In addition, the presence of surface/subsurface carbon at the Co sites showed high anti-sulfur poisoning and anti-oxidant capability. This work was valuable for guiding the design and manipulation of cost-effective and robust hydrogenation catalysts.
