Time-resolved monitoring of the permeability of analytes is of utmost importance in membrane research. Existing methods are restricted to single-point determinations or flat synthetic membranes, limiting access to biologically relevant kinetic parameters (permeation rate constant, permeation coefficients). We now use the recently introduced fluorescent artificial receptor membrane assay (FARMA) as a method to monitor, in real time, the permeation of indole derivatives through liposomal membranes of different lipid compositions. This method is based on the liposomal encapsulation of a chemosensing ensemble or fluorescent artificial receptor, consisting of 2,7-dimethyldiazapyrenium as a fluorescent dye and cucurbit[8]uril as the macrocyclic receptor, that responds to the complexation of a permeating aromatic analyte by fluorescence quenching. FARMA does not require a fluorescent labeling of the analytes and allows access to permeability coefficients in the range from 10(-8) to 10(-4) cm s(-1). The effect of temperature on the permeation rate of a series of indole derivatives across the phospholipid membranes was studied. The activation energies for permeation through POPC/POPS phospholipid membranes were in the range of 28-96 kJ mol(-1). To study the effect of different lipid phases on the membrane permeability, we performed experiments with DPPC/DOPS vesicles, which showed a phase transition from a gel phase to a liquid-crystalline phase, where the activation energies for the permeation process were expected to show a dramatic change. Accordingly, for the permeation of the indole derivatives into the DPPC/DOPS liposomes, discontinuities were observed in the Arrhenius plots, from which the permeation activation energies for the distinct phases could be determined, for example, for tryptamine 245 kJ mol(-1) in the gel phase and 47 kJ mol(-1) in the liquid-crystalline phase.

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 135729-62-3. HPLC of Formula: https://www.ambeed.com/products/135729-62-3.html.

Gramine-based structure optimization to enhance anti-gastric cancer activity

Gramine is a natural indole alkaloid with a wide range of biological activities, but its anti-gastric cancer activity is poor. Herein, a pharmacophore fusion strategy was adopted to design and synthesize a new series of indole-azole hybrids on the structural basis of gramine. Based on our previous studies, different nitrogen-containing five-membered heterocyclic rings and terminal alkyne group were introduced into the indole-based scaffold to investigate their effect on improving the anti-gastric cancer activity of gramine derivatives. Structure-activity relationship (SAR) studies highlighted the role played by terminal alkyne in enhancing the inhibitory effect, and compound 16h displayed the best antiproliferative activity against gastric cancer MGC803 cells with IC50 value of 3.74 mu M. Further investigations displayed compound 16h could induce mitochondria-mediated apoptosis, and caused cell cycle arrest at G2/M phase. Besides, compound 16h could inhibit the metastasis ability of MGC803 cells. Our studies may provide a new strategy for structural optimization of gramine to enhance anti-gastric cancer activity, and provide a potential candidate for the treatment of gastric cancer.

Concise approach to the syntheses of (+/-)-gliocladin C and related diketopiperazine alkaloids

A unique approach to the diketopiperazine indole alkaloid (+/-)-gliocladin C was developed and applied to formal syntheses of the related alkaloids (+/-)-gliocladine C and (+/-)-T988C. The key features of the strategy include an unprecedented nucleophilic addition of a diketopiperazine to an isatin derivative followed by a Friedel-Crafts alkylation of the resultant tertiary alcohol with indole to establish the critical quaternary center. Subsequent reduction of the intermediate oxindole moiety and cyclization then delivered a pivotal hexahydropyrrolo[2,3-b]indole diketopiperazine intermediate that was readily converted into (+/-)-gliocladin C as well as racemic versions of key intermediates in the Overman syntheses of (+)-gliocladine C and (+)-T988C.

Unusual rearrangements in activated indoles: Synthesis of indoloquinolines, dibenzonaphthyridines and indolobenzodiazepines

Reaction of 2-arylindoles with 2-acetamidobenzyl chloride gave 3-alkylated indoles rather than those substituted at nitrogen. Similar reactions with 3-arylindoles gave reduced indoloquinolines, and a 2,3-diphenylindole gave a 3-alkylated indole. On reaction with phosphoryl chloride, the amidobenzylindoles undergo rearrangement to benzonaphthyridines. Similarly, the indoloquinolines undergo rearrangement to benzodiazepino-indoles.
