Mahmood, Abid; Ali Shah, Syed Jawad; Iqbal, Jamshed published the artcile< Design and synthesis of adamantane-1-carbonyl thiourea derivatives as potent and selective inhibitors of h-P2X4 and h-P2X7 receptors: An Emerging therapeutic tool for treatment of inflammation and neurological disorders>, Quality Control of 51605-97-1, the main research area is adamantanoyl thiourea preparation SAR receptor inhibitor inflammation docking; Ca(2+) flux assay; Carboxamides; Fura-2 AM dye; Molecular docking studies; P2XR antagonists; Purinergic signaling; Thiourea derivatives.

Adamantane ring has been reported to exhibit significant inhibitory potential towards P2X receptors, especially for P2X7R. Uniqueness of adamantan radicals in synthesized compounds RC(O)NHC(S)NHR1 [R = adamantan-1-yl; R1 = 2-bromo-4-isopropylphenyl, quinolin-8-yl, 3-(dimethylamino)propan-1-yl, etc.] introduced different substitutes to improve potency and selectivity for the P2XR subtypes used. Among synthesized derivatives, RC(O)NHC(S)NHR1 [R = adamantan-1-yl; R1 = 2-bromo-4-isopropylphenyl, quinolin-8-yl] were found to be most potent and selective inhibitors for h-P2X4R and h-P2X7R, resp. Compound RC(O)NHC(S)NHR1 [R = adamantan-1-yl; R1 = 2-bromo-4-isopropylphenyl] was found to be highly selective for h-P2X4R with IC50 ± SEM = 0.04 ± 0.01μM, that is 22 times more potent than BX-430, a standard selective inhibitor of h-P2X4R. Compound RC(O)NHC(S)NHR1 [R = adamantan-1-yl; R1 = quinolin-8-yl] has IC50 ± SEM of 0.073 ± 0.04μM, which is comparable with the known antagonists of h-P2X7R. In silico studies were also conducted to find the type of interactions as well as mode of inhibition. Compound RC(O)NHC(S)NHR1 [R = adamantan-1-yl; R1 = 2-bromo-4-isopropylphenyl, quinolin-8-yl] were studied for mode of inhibition of P2XRs and both were found to be neg. allosteric modulators.

A palladium-catalyzed intramol. enantioselective Mizoroki-Heck reaction of naphthalenes was developed via dearomative migratory insertion of an endocyclic π-bond of naphthalene, followed by δ-hydride elimination. This reaction relies on the use of chiral sulfonamide phosphine type Xu-Phos ligand, which successfully inhibited the competitive and undesired C-H arylation reaction and efficiently promoted the formation of spirooxindole and spiroisoindolin-1-one products. Synthetic transformations of the product afforded a series of unique heterocyclic compounds with enantiomeric excess (ee) values retained.

A highly efficient potassium carbonate-mediated [3 + 2] cycloaddition reaction of hydrazonoyl chlorides with cinnamic aldehydes to furnish multi-substituted pyrazoles under nontoxic and mild conditions was developed. A plausible stepwise cycloaddition reaction mechanism was proposed. This protocol featured broad substrate coverage, good functional group tolerance, wide scalability, and operational simplicity, as well as conveniently constructed pyrazole scaffolds.

Genetic and pharmacol. evidence indicates that the reduction of ataxia telangiectasia-mutated (ATM) kinase activity can ameliorate mutant huntingtin (mHTT) toxicity in cellular and animal models of Huntington’s disease (HD), suggesting that selective inhibition of ATM could provide a novel clin. intervention to treat HD. Here, we describe the development and characterization of ATM inhibitor mols. to enable in vivo proof-of-concept studies in HD animal models. Starting from previously reported ATM inhibitors, we aimed with few modifications to increase brain exposure by decreasing P-glycoprotein liability while maintaining potency and selectivity. Here, we report brain-penetrant ATM inhibitors that have robust pharmacodynamic (PD) effects consistent with ATM kinase inhibition in the mouse brain and an understandable pharmacokinetic/PD (PK/PD) relationship. Compound 17 engages ATM kinase and shows robust dose-dependent inhibition of X-ray irradiation-induced KAP1 phosphorylation in the mouse brain. Furthermore, compound 17 protects against mHTT (Q73)-induced cytotoxicity in a cortical-striatal cell model of HD.

Chen, Xiang-Yu; Zhao, Kun; Liu, Qiang; Zhi, Ying; Ward, James; Rissanen, Kari; Enders, Dieter published the artcile< N-heterocyclic carbene-catalyzed 1,6-addition of homoenolate equivalent intermediates: asymmetric synthesis of nonspirocyclic quaternary oxindoles>, Related Products of 3893-18-3, the main research area is nonspirocyclic diarylmethyl isoxazolyl oxindole ester preparation stereoselective; quinone methide cinnamaldehyde isatin isoxazole cycloaddition heterocyclic carbene catalyst.

Although there is a growing interest in developing asym. 1,6-addition reactions of carbon nucleophiles to Michael acceptors, the corresponding 1,6-addition of homoenolates remains an unsolved problem. Currently, the N-heterocyclic carbene (NHC)-catalyzed cycloadditions of homoenolate equivalent intermediates have achieved widespread success. However, considerable limitations still exist for the linear reactions with electron-deficient alkenes, which are limited to 1,4-Michael acceptors. This report presents the first NHC-catalyzed asym. homoenolate addition of enals to 1,6-Michael acceptors. The strategy leads to the challenging nonspirocyclic 3,3-disubstituted oxindoles with two adjacent stereocenters, a quaternary and a trisubstituted one, in good yields and high stereoselectivities with a wide variety of substrates.
