A new series of gallic hydrazones containing an indole moiety was synthesized through the reaction of gallic hydrazide and different indole carboxaldehydes. Their antioxidant activities were determined on DPPH radical scavenging and inhibition of lipid peroxidation. The in-vitro cytotoxic activities of the compounds were evaluated against HCT-116 (human colon cancer cell line) and MCF-7 (estrogen-dependent human breast cancer cell line) by the MTT method. An attempt to correlate the biological results with their structural characteristics has been done. A limited positive structure activity relationship was found between cytotoxic and antioxidant activities. Gallic acid derivatives are naturally occurring compounds with interesting biological properties. Similarly, indolic compounds represent an important class of therapeutical agents in medicinal chemistry. A series of hybrid molecules incorporating these two pharmacophores has been synthesized and assessed for their antioxidant and cytotoxic activities. Copyright

A new palladium-catalyzed asymmetric addition reaction of indoles to alkoxyallenes is reported. Remarkably, the reaction showed complete regioselectivity toward the nitrogen. A new mechanism distinct from that of conventional pi-allyl chemistry is proposed to explain this unique selectivity. The utility of the reaction is demonstrated by highly efficient and flexible synthesis of N-glycosylindoles.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 93247-78-0 is helpful to your research. Safety of Methyl 1H-indole-7-carboxylate

Heterocyclic sulfinates are effective reagents in palladium-catalyzed coupling reactions with aryl and heteroaryl halides, often providing high yields of the targeted biaryl. However, the preparation and purification of complex heterocylic sulfinates can be problematic. In addition, sulfinate functionality is not tolerant of the majority of synthetic transformations, making these reagents unsuitable for multistep elaboration. Herein, we show that heterocyclic allylsulfones can function as latent sulfinate reagents and, when treated with a Pd(0) catalyst and an aryl halide, undergo deallylation, followed by efficient desulfinylative cross-coupling. A broad range of allyl heteroarylsulfones are conveniently prepared, using several complementary routes, and are shown to be effective coupling partners with a variety of aryl and heteroaryl halides. We demonstrate that the allylsulfone functional group can tolerate a range of standard synthetic transformations, including orthogonal C- and N-coupling reactions, allowing multistep elaboration. The allylsulfones are successfully coupled with a variety of medicinally relevant substrates, demonstrating their applicability in demanding cross-coupling transformations. In addition, pharmaceutical agents crizotinib and etoricoxib were prepared using allyl heteroaryl sulfone coupling partners, further demonstrating the utility of these new reagents.

Hepatocellular carcinoma (HCC) accounts for most cases of liver cancer worldwide; contraction of hepatitis C (HCV) is considered a major risk factor for liver cancer even when individuals have not developed formal cirrhosis. Global, untargeted metabolic profiling methods were applied to serum samples from patients with either HCV alone or HCC (with underlying HCV). The main objective of the study was to identify metabolite based biomarkers associated with cancer risk, with the long term goal of ultimately improving early detection and prognosis. Serum global metabolite profiles from patients with HCC (n= 37) and HCV (n= 21) were obtained using high performance liquid chromatography-mass spectrometry (HPLC-MS) methods. The selection of statistically significant metabolites for partial least-squares discriminant analysis (PLS-DA) model creation based on biological and statistical significance was contrasted to that of a traditional approach utilizing p-values alone. A PLS-DA model created using the former approach resulted in a model with 92% sensitivity, 95% specificity, and an AUROC of 0.93. A series of PLS-DA models iteratively utilizing three to seven metabolites that were altered significantly (p<. 0.05) and sufficiently (FC. ?. 0.7 or FC. ?. 1.3) showed good performance using p-values alone ; the best of these PLS-DA models was capable of generating 73% sensitivity, 95% specificity, and an AUROC of 0.92. Metabolic profiles derived from LC-MS readily distinguish patients with HCC and HCV from those with HCV only. Differences in the metabolic profiles between high-risk individuals and HCC indicate the possibility of identifying the early development of liver cancer in at risk patients. The use of biological significance as a selection process prior to PLS-DA modeling may offer improved probabilities for translation of newly discovered biomarkers to clinical application.

Trifluoromethanesulfinyl chloride (CF3SOCl) has been introduced as a new reagent for C?H trifluoromethylthiolation of indoles, thiophenes, and ketones under catalyst-free conditions and in the absence of reductant. The disproportionation of CF3SOCl to CF3SO2Cl and CF3SCl provides two pathways for the trifluoromethylthiolation. Direct trifluoromethylthiolation with CF3SCl or trifluoromethylsulfoxidation with CF3SOCl is followed by reduction with CF3SOCl. This reagent can be used to functionalize benzothiophenes, benzofurans, and indenes under the promotion of Ag2CO3. It can also be used for trifluoromethylthiolation of thiols and benzeneselenols, and 1,2-bifunctional chlorotrifluoromethylthiolation of indoles, styrenes, and alkyenes. The method can also be extended for difluorometylthiolation reactions using CF2HSOCl.

Converging evidence has suggested that anandamide (AEA), an endogenous agonist of cannabinoid (CB) receptors, can directly interact with certain types of ligand-gated ion channels (LGICs). However, little is known about the molecular and cellular mechanisms of AEA-induced direct effects on LGICs. Here, we report that AEA inhibited the function of serotonin-gated ion channels (5-HT3A) expressed in Xenopus laevis oocytes and human embryonic kidney 293 cells in a manner that was dependent on the steady-state receptor density at the cell surface. The magnitude of AEA inhibition was inversely correlated with the expression levels of receptor protein and function. With increasing surface receptor expression, the magnitude of AEA inhibition decreased. Consistent with this idea, pretreatment with actinomycin D, which inhibits transcription, decreased the amplitude of current activated by maximal concentrations of 5-hydroxytryptamine (5-HT) and increased the magnitude of AEA inhibition. AEA did not significantly alter 5-HT3A receptor trafficking. However, AEA accelerated 5-HT3A receptor desensitization time in a concentration-dependent manner without significantly changing receptor activation and deactivation time. The desensitization time was correlated with the AEA-induced inhibiting effect and mean 5-HT current density. Applications of 5-hydroxyindole and nocodazole, a microtubule disruptor, significantly slowed 5-HT3A receptor desensitization and reduced the magnitude of AEA inhibition. These observations suggest that 5-HT3 receptor density at the steady state regulates receptor desensitization kinetics and the potency of AEA-induced inhibiting effect on the receptors. The inhibition of 5-HT3 receptors by AEA may contribute to its physiological roles in control of pain and emesis. Copyright
