Li, Xuemei; Hong, Duidui; Zhang, Mengmeng; Xu, Lei; Zhou, Yubo; Li, Jia; Liu, Tao published the article 《Development of peptide epoxyketones as selective immunoproteasome inhibitors》. Keywords: epoxyketone peptide synthesis peptidomimetic immunoproteasome inhibitor structure activity; antitumor agent drug design mol docking hydrogen bond chirality; isocyanate peptide coupling; Epoxyketones; Immunoproteasome inhibitor; Multiple myeloma; Selectivity.They researched the compound: 4-Methoxypiperidine( cas:4045-24-3 ).Product Details of 4045-24-3. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:4045-24-3) here.

A series of epoxyketone analogs with varying N-caps and P3-configurations were designed, synthesized and evaluated. We found that D-Ala in P3 was crucial for β5i selectivity over β5c. Notably, compounds (I) (R1 = II) (β5i IC50 = 26.0 nM, 25-fold selectivity) and I (r1 = III) (β5i IC50 = 25.1 nM, 24-fold selectivity) with the D-configuration at P3 were the most selective inhibitors. Although I (R1 = II and III) showed only moderate anti-proliferative activity against RPMI-8226 and MM.1S cell lines, based on our experiments, it indicates that the inhibition of β5i alone is not sufficient to exert anticancer effects and may rely on the complementary inhibition of β1i, β5c and β5i. These data further increase our understanding of immunoproteasome inhibitors in hematol. malignancies.

There is still a lot of research devoted to this compound(SMILES：COC1CCNCC1)Product Details of 4045-24-3, and with the development of science, more effects of this compound(4045-24-3) can be discovered.

Formula: C5H3ClFN. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 4-Chloro-2-fluoropyridine, is researched, Molecular C5H3ClFN, CAS is 34941-92-9, about The reactivity of 2-fluoro- and 2-chloropyridines toward sodium ethoxide: Factors governing the rates of nucleophilic (het)aromatic substitutions. Author is Schlosser, Manfred; Rausis, Thierry.

The relative displacement rates of the halide substituent from 2-fluoro- and 2-chloropyridines by EtONa in EtOH at +25° were assessed by competition kinetics. The 2-fluoropyridine reacts 320 times faster than the chloro analog. A CF3 group increases the reactivity more than single halogen atoms do, whatever the element, and the latter are superior to Me3Si groups. Substituents accommodated at the 4-position operate through their inductive effect, whereas at the 3-position, this action may be attenuated by steric hindrance. Almost all 5-substituents enhance the rate of the nucleophilic substitution occurring at the 2-position. The sole exception concerns the F-atom at the 5-position which retards the reaction, presumably by lone-pair/lone-pair repulsion with the neg. charge building up at the central C-atom of the intermediate Meisenheimer complex. The substituent effects are additive. Therefore, by using the increments derived from the present work, the rates of future reactions should be predictable with fair accuracy.

There is still a lot of research devoted to this compound(SMILES：ClC1=CC(=NC=C1)F)Formula: C5H3ClFN, and with the development of science, more effects of this compound(34941-92-9) can be discovered.

Application In Synthesis of 4-Methoxypiperidine. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 4-Methoxypiperidine, is researched, Molecular C6H13NO, CAS is 4045-24-3, about Discovery of Novel Thiophene-arylamide Derivatives as DprE1 Inhibitors with Potent Antimycobacterial Activities. Author is Wang, Pengxu; Batt, Sarah M.; Wang, Bin; Fu, Lei; Qin, Rongfei; Lu, Yu; Li, Gang; Besra, Gurdyal S.; Huang, Haihong.

In this study, we report the design and synthesis of a series of novel thiophene-arylamide compounds derived from the noncovalent decaprenylphosphoryl-β-D-ribose 2′-epimerase (DprE1) inhibitor TCA1 through a structure-based scaffold hopping strategy. Systematic optimization of the two side chains flanking the thiophene core led to new lead compounds bearing a thiophene-arylamide scaffold with potent antimycobacterial activity and low cytotoxicity. Compounds I, II, III [X = H,F] exhibited potent in vitro activity against both drug-susceptible (min. inhibitory concentration (MIC) = 0.02-0.12μg/mL) and drug-resistant (MIC = 0.031-0.24μg/mL) tuberculosis strains while retaining potent DprE1 inhibition (half maximal inhibitory concentration (IC50) = 0.2-0.9μg/mL) and good intracellular antimycobacterial activity. In addition, these compounds showed good hepatocyte stability and low inhibition of the human ether-á-go-go related gene (hERG) channel. The representative compound III [X = H] with acceptable pharmacokinetic property demonstrated significant bactericidal activity in an acute mouse model of tuberculosis. Moreover, the mol. docking study of template compound I provides new insight into the discovery of novel antitubercular agents targeting DprE1.

Keywords: indoline tetrahydroisoquinoline aminobenzimidazole preparation; structure activity relationship pharmacokinetics NOD1 induced NFkappaB activation inhibitor. We’ll tell you more about this compound (cas:879562-21-7).

NOD1 (nucleotide-binding oligomerization domain 1) protein is a member of the NLR (NACHT and leucine rich repeat domain containing proteins) protein family, which plays a key role in innate immunity as a sensor of specific microbial components derived from bacterial peptidoglycans and induction of inflammatory responses. Mutations in NOD proteins have been associated with various inflammatory diseases that affect NF-κB (nuclear factor κB) activity, a major signaling pathway involved in apoptosis, inflammation, and immune response. A luciferase-based reporter gene assay was utilized in a high-throughput screening program conducted under the NIH-sponsored Mol. Libraries Probe Production Center Network program to identify the active scaffolds. Herein, we report the chem. synthesis, structure-activity relationship studies, downstream counterscreens, secondary assay data, and pharmacol. profiling of the 2-aminobenzimidazole lead, I, as a potent and selective inhibitor of NOD1-induced NF-κB activation.

SDS of cas: 4045-24-3. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 4-Methoxypiperidine, is researched, Molecular C6H13NO, CAS is 4045-24-3, about Optimization of WZ4003 as NUAK inhibitors against human colorectal cancer. Author is Yang, Huali; Wang, Xiaobing; Wang, Cheng; Yin, Fucheng; Qu, Lailiang; Shi, Cunjian; Zhao, Jinhua; Li, Shang; Ji, Limei; Peng, Wan; Luo, Heng; Cheng, Maosheng; Kong, Lingyi.

NUAK, the member of AMPK (AMP-activated protein kinase) family of protein kinases, is phosphorylated and activated by the LKB1 (liver kinase B1) tumor suppressor protein kinase. Recent work has indicated that NUAK1 is a key component of the antioxidant stress response pathway, and the inhibition of NUAK1 will suppress the growth and survival of colorectal tumors. As a promising target for anticancer drugs, few inhibitors of NUAK were developed. With this goal in mind, based on NUAK inhibitor WZ4003, a series of derivatives has been synthesized and evaluated for anticancer activity. Compound I, a derivative of WZ4003 by removing a methoxy group, was found to be the most potential one with stronger inhibitory against NUAK1/2 enzyme activity, tumor cell proliferation and inducing apoptosis of tumor cells. By in vivo efficacy evaluations of colorectal SW480 xenografts, I suppresses tumor growth more effectively with an excellent safety profile in vivo and is therefore seen as a suitable candidate for further investigation.
