Design, synthesis and biological evaluation of N-hydroxy- aminobenzyloxyarylamide analogues as novel selective kappa opioid receptor antagonists

Aminobenzyloxyarylamide derivatives la-i and 2a-t were designed and synthesized as novel selective kappa opioid receptor (KOR) antagonists. The benzoyl amide moiety of LY2456302 was changed into N-hydroxybenzamide and benzisoxazole-3(2H)-one to investigate whether it could increase the binding affinity or selectivity for KOR. All target compounds were evaluated in radioligand binding assays for opioid receptor binding affinity. These efforts led to the identification of compound lc (kappa K-i = 179.9 nM), which exhibited high affinity for KOR. Moreover, the selectivity of KOR over MOR and DOR increased nearly 2-fold and 7-fold, respectively, compared with ( +/- )LY2456302.

Ring-enlargement and ring-opening reactions of benzoxazole, thiazoles, and benzisoxazole by zirconocene-alkyne complexes

Zirconocene alkyne complexes Cp(2)Zr(L)(Me(3)SiC(2)R) (L = Py, THF; R = SiMe(3), tBu) react with heterocyclic compounds like benzoxazole and related thiazoles to yield ring-expanded adducts Cp(2)Zr-C(SiMe(3))=C(R)-CH=N-o-C6H4-X (1-3) and Cp(2)Zr-C(SiMe(3))=C(SiMe(3))-CH=N-C(R’)=C(R’)-X (R’ = Me, H) (4, 5) by formal C-X (X = O, S) bond cleavage and coupling with the coordinated alkyne. In the case of benzisoxazole, the alkyne is not coupled but eliminated, and with ring-enlargement of the benzisoxazole a N-bridged dimer [Cp(2)Zr-N=CH-o-C6H4-O](2) (6) is formed. The obtained complexes 1, 3, and 6 were characterized by NMR spectra and crystal structure analysis.

Heavy-Atom Tunneling Through Crossing Potential Energy Surfaces: Cyclization of a Triplet 2-Formylarylnitrene to a Singlet 2,1-Benzisoxazole

Not long ago, the occurrence of quantum mechanical tunneling (QMT) chemistry involving atoms heavier than hydrogen was considered unreasonable. Contributing to the shift of this paradigm, we present here the discovery of a new and distinct heavy-atom QMT reaction. Triplet syn-2-formyl-3-fluorophenylnitrene, generated in argon matrices by UV-irradiation of an azide precursor, was found to spontaneously cyclize to singlet 4-fluoro-2,1-benzisoxazole. Monitoring the transformation by IR spectroscopy, temperature-independent rate constants (k approximate to 1.4×10(-3) s(-1); half-life of approximate to 8 min) were measured from 10 to 20 K. Computational estimated rate constants are in fair agreement with experimental values, providing evidence for a mechanism involving heavy-atom QMT through crossing triplet to singlet potential energy surfaces. Moreover, the heavy-atom QMT takes place with considerable displacement of the oxygen atom, which establishes a new limit for the heavier atom involved in a QMT reaction in cryogenic matrices.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 6009-70-7. Formula: C2H10N2O5.

A new series of spiro-quinoline compounds have been accomplished by the reaction of barbituric acid or thiobarbituric acid with derivatives of benzisoxazole-5-carbaldehyde or 2-substituted benzaldehyde. These compounds were evaluated for their in vitro cytotoxicity on two mammalian cancer cell lines MCF-7 and KB. The compounds exhibit cytotoxicity against these cell lines in micromolar range. Among the series of compounds, 11(a-j) particularly 11b and 11e showed relatively good activity against both the tested cell lines. Compound 11b was found to exhibit the highest cytotoxic activity with IC50 value 90.2 mu M for MCF-7 and 49.8 mu M for KB cell line.

Imprinted polymers: Versatile new tools in synthesis

The use of molecularly imprinted polymers in synthetic organic chemistry is reviewed. These materials are prepared in the presence of a template for which they carry a functional and stereochemical memory and can be likened to artificial antibodies or enzymes. Their unique properties have been exploited by the use of imprinted polymers as stereo- and regio-selective solid supports in condensation reactions and hydride reduction, as protecting groups in the acylation of polyols and as catalysts to enhance the rates of reactions as diverse a Diels-Alder reaction, an Aldol condensation, beta-elimination, the benzisoxazole isomerization, transesterification and ester hydrolyses.

Dependence of isotope effects on conformation in decarboxylation of 3-carboxybenzisoxazoles

Conformational analysis of 3-carboxybenzisoxazole and its 4-hydroxy-substituted derivative was performed by a semiempirical molecular dynamics approach. The most stable conformers of the reactants and transition states from these simulations were used in calculations of the kinetic isotope effects of carbon, nitrogen, oxygen and deuterium. It was shown that the conformation of either reactant or transition state can significantly affect the magnitude of an isotope effect, especially for atoms involved in hydrogen bonding.

Rational design of novel benzisoxazole derivatives with acetylcholinesterase inhibitory and serotoninergic 5-HT4 receptors activities for the treatment of Alzheimer’s disease

A rigidification strategy was applied to the preclinical candidate donecopride, an acetylcholinesterase inhibitor possessing 5-HT4R agonist activity. Inspired by promising bioactive benzisoxazole compounds, we have conducted a pharmacomodulation study to generate a novel series of multitarget directed ligands. The chemical synthesis of the ligand was optimized and compounds were evaluated in vitro against each target and in cellulo. Structure-activity relationship was supported by docking analysis in human acetylcholinesterase binding site. Among the synthesized compounds, we have identified a novel hybrid 32a (3-[2-[1-(cyclohexylmethyl)-4-piperidyl]ethyl]-4-methoxy-1,2-benzoxazole) able to display nanomolar acetylcholinesterase inhibitory effects and nanomolar Ki for 5-HT4R.
