Chang, Ying-Hsin published the artcileEffects of cannabinoids on LPS-stimulated inflammatory mediator release from macrophages: involvement of eicosanoids, Product Details of C23H23ClN2O4, the publication is Journal of Cellular Biochemistry (2001), 81(4), 715-723, database is CAplus and MEDLINE.

螖⁹-Tetrahydrocannabinol (螖⁹-THC) is the major psychoactive component of marijuana and elicits pharmacol. actions via cannabinoid receptors. Anandamide (AEA) and 2-arachidonoyl-glycerol (2-AG) are endogenous ligands for cannabinoid receptors, which because of their structural similarities to arachidonic acid (AA), AEA, and 2-AG could serve as substrates for lipoxygenases and cyclooxygenases (COXs) that metabolize polyunsaturated fatty acids to potent bioactive mols. In this study, we have compared the effects of 螖⁹-THC, AEA, 2-AG, and another cannabinoid agonist, indomethacin morpholinylamide (IMMA), on lipopolysaccharide (LPS)-induced NO, IL-6, and PGE₂ release from J774 macrophages. 螖⁹-THC, IMMA, and AEA diminish LPS-induced NO and IL-6 production in a concentration-dependent manner. 2-AG inhibits the production of IL-6 but slightly increases iNOS-dependent NO production 螖⁹-THC and IMMA also inhibit LPS-induced PGE₂ production and COX-2 induction, while AEA and 2-AG have no effects. These discrepant results of 2-AG on iNOS and COX-2 induction might be due to its bioactive metabolites, AA and PGE₂, whose incubation cause the potentiation of both iNOS and COX-2 induction. On the contrary, the AEA metabolite, PGE₂-ethanolamide, influences neither the LPS-induced NO nor IL-6 production Taken together, direct cannabinoid receptor activation leads to anti-inflammatory action via inhibition of macrophage function. The endogenous cannabinoid, 2-AG, also serves as a substrate for COX-catalyzing PGE₂ production, which in turn modulates the action of CB2.

Bartscht, Tobias published the artcileThe Src family kinase inhibitors PP2 and PP1 effectively block TGF-beta1-induced cell migration and invasion in both established and primary carcinoma cells, Category: indole-building-block, the publication is Cancer Chemotherapy and Pharmacology (2012), 70(2), 221-230, database is CAplus and MEDLINE.

Purpose: We have previously demonstrated that in pancreatic ductal adenocarcinoma (PDAC)-derived cell lines, the common Src family kinase inhibitors PP2 and PP1 effectively inhibited morphol. alterations associated with TGF尾1-mediated epithelial-to-mesenchymal transition (EMT) by blocking the kinase activity of the TGF-尾 type I receptor ALK5 rather than Src (Ungefroren et al. in Curr Cancer Drug Targets 11:524, 2011). In this report, the ability of PP2 and PP1, the more specific Src inhibitor SU6656, and the ALK5 inhibitor SB431542 to functionally block TGF-尾1-dependent EMT and cell motility in established PDAC (Panc-1, Colo 357) and primary NSCLC (Tu459) cell lines were investigated. Methods: The effects of PP2, PP1, SU6656, and SB431542 on TGF-尾1-dependent cell scattering/EMT, cell migration/invasion, and expression of invasion-associated genes were measured by using the real-time cell anal. assay on the xCELLigence system and quant. real-time RT-PCR, resp. Results: In all three cell lines tested, PP1, PP2, and SB431542 effectively blocked TGF-尾1-induced cell scattering/EMT, migration, and invasion and in Colo 357 cells inhibited the induction of the invasion-associated MMP2 and MMP9 genes. In contrast, SU6656 only blocked TGF-尾1-induced invasion in Panc-1 and Tu459 but not Colo 357 cells. PP1, and to a greater extent PP2, also inhibited the high spontaneous migratory activity of Panc-1 cells expressing a kinase-active ALK5 mutant. Conclusions: These data provide evidence that PP2 and PP1 are powerful inhibitors of TGF-尾-induced cell migration and invasion in vitro and directly target ALK5. Both agents may be useful as dual TGF-尾/Src inhibitors in exptl. therapeutics to prevent metastatic spread in late-stage PDAC and NSCLC.

Tan, Yu Jia published the artcileAmide-Amine Replacement in Indole-2-carboxamides Yields Potent Mycobactericidal Agents with Improved Water Solubility, Recommanded Product: 5-Fluoro-1H-indole-2-carbaldehyde, the publication is ACS Medicinal Chemistry Letters (2021), 12(5), 704-712, database is CAplus and MEDLINE.

Indolecarboxamides are potent but poorly soluble mycobactericidal agents. Here, it was found that modifying the incipient scaffold by amide-amine substitution and replacing the indole ring with benzothiophene or benzoselenophene led to striking (10-20-fold) improvements in solubility Potent activity could be achieved without the carboxamide linker but not in the absence of the indole ring. The indolylmethylamine, N-cyclooctyl-6-trifluoromethylindol-2-ylmethylamine (MIC_90Mtb 0.13渭M, MBC_99.9Mtb 0.63渭M), exemplifies a promising member that is more soluble and equipotent to its carboxamide equivalent It is also an inhibitor of the mycolate transporter MmpL3, a property shared by the methylamines of benzothiophene and benzoselenophene.

An improved procedure for the synthesis of indole-2-carboxylic acid esters, e.g. Et 1-methoxy-1H-indole-2-carboxylate, in excellent yields has been achieved by the condensation of 2-halo aryl aldehydes or ketones and Et isocyanoacetate using ionic liquid under controlled microwave irradiation (100 W) at 50 掳C. This method offers a number of advantages in terms of methodol., high-product yield, short period of conversion, mild reaction conditions and easy workup.

A preliminary investigation into the prospect of a common synthetic intermediate for the synthesis of a variety of indole alkaloids has led to a synthesis of substituted piperidinones and the corresponding piperidines. These common natural product cores are accessed via a reductive amination-lactamization sequence of di-Me 3-ethyl-3-formylpimelate. The synthetic utility of this initial study has been displayed in the formal synthesis of (±)-quebrachamine.

Morgan, Amanda J. published the artcileDetection of Cyclooxygenase-2-Derived Oxygenation Products of the Endogenous Cannabinoid 2-Arachidonoylglycerol in Mouse Brain, Recommanded Product: 2-(1-(4-Chlorobenzoyl)-5-methoxy-2-methyl-1H-indol-3-yl)-1-morpholinoethanone, the publication is ACS Chemical Neuroscience (2018), 9(7), 1552-1559, database is CAplus and MEDLINE.

Cyclooxygenase-2 (COX-2) catalyzes the formation of prostaglandins, which are involved in immune regulation, vascular function, and synaptic signaling. COX-2 also inactivates the endogenous cannabinoid (eCB) 2-arachidonoylglycerol (2-AG) via oxygenation of its arachidonic acid backbone to form a variety of prostaglandin glyceryl esters (PG-Gs). Although this oxygenation reaction is readily observed in vitro and in intact cells, detection of COX-2-derived 2-AG oxygenation products has not been previously reported in neuronal tissue. Here we show that 2-AG is metabolized in the brain of transgenic COX-2-overexpressing mice and mice treated with the lipopolysaccharide to form multiple species of PG-Gs that are detectable only when monoacylglycerol lipase is concomitantly blocked. Formation of these PG-Gs is prevented by acute pharmacol. inhibition of COX-2. These data provide evidence that neuronal COX-2 is capable of oxygenating 2-AG to form a variety PG-Gs in vivo and support further investigation of the physiol. functions of PG-Gs.

Paveliev, Mikhail published the artcileAcute brain trauma in mice followed by longitudinal two-photon imaging, Synthetic Route of 330161-87-0, the publication is Journal of Visualized Experiments (2014), e51559/1-e51559/8, database is CAplus and MEDLINE.

Although acute brain trauma often results from head damage in different accidents and affects a substantial fraction of the population, there is no effective treatment for it yet. Limitations of currently used animal models impede understanding of the pathol. mechanism. Multiphoton microscopy allows studying cells and tissues within intact animal brains longitudinally under physiol. and pathol. conditions. Here, we describe two models of acute brain injury studied by means of two-photon imaging of brain cell behavior under posttraumatic conditions. A selected brain region is injured with a sharp needle to produce a trauma of a controlled width and depth in the brain parenchyma. Our method uses stereotaxic prick with a syringe needle, which can be combined with simultaneous drug application. We propose that this method can be used as an advanced tool to study cellular mechanisms of pathophysiol. consequences of acute trauma in mammalian brain in vivo. In this video, we combine acute brain injury with two preparations: cranial window and skull thinning. We also discuss advantages and limitations of both preparations for multisession imaging of brain regeneration after trauma.
