B.;Xiang, Jianing;Guan, Xiaoming;Wren, Paul;Ren, Feng research published 《 Discovery of Novel 1-Cyclopentenyl-3-phenylureas as Selective, Brain Penetrant, and Orally Bioavailable CXCR2 Antagonists》, the research content is summarized as follows. CXCR2 has emerged as a therapeutic target for not only peripheral inflammatory diseases but also neurol. abnormalities in the central nervous system (CNS). Herein, we describe the discovery of a novel 1-cyclopentenyl-3-phenylurea series as potent and CNS penetrant CXCR2 antagonists. Extensive SAR studies, wherein mols.’ property forecast index (PFI) was carefully optimized for overall balanced developability profiles, led to the discovery of the advanced lead compound I with a desirable PFI. Compound I demonstrated good in vitro pharmacol. with excellent selectivity over CXCR1 and other chemokine receptors. Rat and dog pharmacokinetics (PK) revealed good oral bioavailability, high oral exposure, and desirable elimination half-life of the compound in both species. In addition, the compound demonstrated dose-dependent efficacy in the in vivo pharmacol. neutrophil infiltration “air pouch” model in rodents after oral administration. Further, compound I is a CNS penetrant mol. with high unbound fraction in brain tissue.

Lopez-Grancha, Matilde;Bernardelli, Patrick;Moindrot, Nicolas;Genet, Elisabeth;Vincent, Carine;Roudieres, Valerie;Krick, Alain;Sabuco, Jean-Francois;Machnik, David;Ibghi, Delphine;Pradier, Laurent;Taupin, Veronique research published 《 A novel selective PKR inhibitor restores cognitive deficits and neurodegeneration in Alzheimer disease experimental models》, the research content is summarized as follows. In Alzheimer disease (AD), the double-strand RNA-dependent kinase protein kinase R (PKR )/EIF2AK2 is activated in brain with increased phosphorylation of its substrate eukaryotic initiation factor 2α (eIF2α). AD risk-promoting factors, such as ApoE4 allele or the accumulation of neurotoxic amyloid-β oligomers (AβOs), have been associated with activation of PKR-dependent signaling. Here, we report the discovery of a novel potent and selective PKR inhibitor (SAR439883) and demonstrate its neuroprotective pharmacol. activity in AD exptl. models. In ApoE4 human replacement male mice, 1-wk oral treatment with SAR439883 rescued short-term memory impairment in the spatial object recognition test and dose-dependently reduced learning and memory deficits in the Barnes maze test. Moreover, in AβO-injected male mice, a 2-wk administration of SAR439883 in diet dose-dependently ameliorated the AβO-induced cognitive impairment in both Y-maze and Morris Water Maze, prevented loss of synaptic proteins, and reduced levels of the proinflammatory cytokine interleukin-1β. In both mouse models, these effects were associated with a dose-dependent inhibition of brain PKR activity as measured by both PKR occupancy and partial lowering of peIF2α levels. Our results provide evidence that selective pharmacol. inhibition of PKR by a small selective mol. can rescue memory deficits and prevent neurodegeneration in animal models of AD-like pathol., suggesting that inhibition of PKR is a potential therapeutic approach for AD.

Application In Synthesis of 72824-04-5, Allylboronic acid pinacol ester is a useful research compound. Its molecular formula is C9H17BO2 and its molecular weight is 168.04 g/mol. The purity is usually 95%.
Allylboronic acid pinacol ester is an allylation reagent that is used to produce aldehydes from ketones. It reacts with water, yielding the desired product and formaldehyde as a byproduct. The reaction proceeds through a sequence of steps, in which the boronate ester first reacts with water to form an allylboronate ion and hydrogen gas. This intermediate then reacts with potassium t-butoxide to produce the desired allyl alcohol and potassium borohydride. Finally, the palladium complex catalyst reduces the carbonyl group of the starting material, converting it into an aldehyde. Allylboronic acid pinacol ester is commercially available as a white solid, but can also be synthesized from 2-chloro-5-pinacolylborane (pinacol) in high yield using catalytic cross coupling reactions., 72824-04-5.

Liu, Yong-Zhe;Pan, Li-Hua;Bai, Yu;Yang, Kun;Dong, Pei-Pei;Fang, Zhong-Ze research published 《 Per- and polyfluoroalkyl substances exert strong inhibition towards human carboxylesterases》, the research content is summarized as follows. PFASs are highly persistent in both natural and living environment, and pose a significant risk for wildlife and human beings. The present study was carried out to determine the inhibitory behaviors of fourteen PFASs on metabolic activity of two major isoforms of carboxylesterases (CES). The probe substrates 2-(2-benzoyl-3-methoxyphenyl) benzothiazole (BMBT) for CES1 and fluorescein diacetate (FD) for CES2 were utilized to determine the inhibitory potentials of PFASs on CES in vitro. The results demonstrated that perfluorododecanoic acid (PFDoA), perfluorotetradecanoic acid (PFTA) and perfluorooctadecanoic acid (PFOcDA) strongly inhibited CES1 and CES2. The half inhibition concentration (IC₅₀) value of PFDoA, PFTA and PFOcDA for CES1 inhibition was 10.6μM, 13.4μM and 12.6μM, resp. The IC₅₀ for the inhibition of PFDoA, PFTA and PFOcDA towards CES2 were calculated to be 9.56μM, 17.2μM and 8.73μM, resp. PFDoA, PFTA and PFOcDA exhibited noncompetitive inhibition towards both CES1 and CES2. The inhibition kinetics parameters (K_i) were 27.7μM, 26.9μM, 11.9μM, 4.04μM, 29.1μM, 27.4μM for PFDoA-CES1, PFTA-CES1, PFOcDA-CES1, PFDoA-CES2, PFTA-CES2, PFOcDA-CES2, resp. In vitro-in vivo extrapolation (IVIVE) predicted that when the plasma concentrations of PFDoA, PFTA and PFOcDA were greater than 2.77μM, 2.69μM and 1.19μM, resp., it might interfere with the metabolic reaction catalyzed by CES1 in vivo; when the plasma concentrations of PFDoA, PFTA and PFOcDA were greater than 0.40μM, 2.91μM, 2.74μM, it might interfere with the metabolic reaction catalyzed by CES2 in vivo. Mol. docking was used to explore the interactions between PFASs and CES. In conclusion, PFASs were found to cause inhibitory effects on CES in vitro, and this finding would provide an important exptl. basis for further in-vivo testing of PFASs focused on CES inhibition endpoints.
