Total syntheses of the slime mold alkaloid arcyriacyanin A

Arcyriacyanin A (1) has been synthesized by three different routes. In the first synthesis the bisbromomagnesium salt of 2,4′-biindole (5) was treated with dibromomaleimide (6) to yield arcyriacyanin A (1). The second approach used an intramolecular Hock reaction for the cyclization of a 4-(triflyloxy)arcyriarubin 8 to N-methylarcyriacyanin A (2). Thirdly, compound 2 was obtained by a domino Heck reaction between 3-bromo-4-[1(tert-butoxycarbonyl)indol-3-yl]-1-methylmaleimide (9) and 4-bromoindole (10). The N-methyl derivative 2 could be transformed into arcyriacyanin A (1) by standard methods.

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 1122-10-7 is helpful to your research. Related Products of 1122-10-7

Thermally cleavable surfactants

Two new surfactant molecules are reported which contain thermally labile Diels-Alder adducts connecting the polar and non-polar sections of each molecule. The two surfactants possess identical non-polar dodecyl tail segments but exhibit different polar headgroups. The surfactants become soluble in water when anionic salts are formed through the deprotonation of the surfactant headgroups by the addition of potassium hydroxide. When either surfactant is exposed to temperature above about 60 C., the retro Diels-Alder reaction occurs, yielding hydrophilic and hydrophobic fragments and the aqueous solutions of the surfactants subsequently exhibit loss of all surface-active behavior.

Homoarcyriaflavin: Synthesis of Ring-Expanded Arcyriaflavin Analogues

The construction of the ring-expanded carbazole system, forming arcyriaflavin homologues, is efficiently accomplished by the reaction of 2,2?-bridged bis-indoles with 3,4-dibromo-2,5-dihydro-1H-2,5-pyrroledione derivatives under Grignard conditions. A ring size of up to nine members in the central ring is achievable. Substitutions either at the indole system or at the imide-N are also possible. The conformation of homoarcyriaflavins as a cross-link between the rigid arcyriaflavins and the flexible arcyriarubins was investigated by NMR, X-ray, and semiempiric quantum chemical calculation methods.

Comparison of anticancer activity and hplc-dad determination of selected isoquinoline alkaloids from thalictrum foetidum, berberis sp. And chelidonium majus extracts

Background: Plants are an important origin of natural substances that The raw material for various pharmaceutical and therapeutic applications due to The presence of phytochemicals, such as alkaloids. Alkaloids, which are found in different plant species, possess numerous biological activities. Some alkaloids have strong cytotoxic effects on various cancer cells. The search for new drugs to treat various cancers is one of The most important challenges of modern scientific research. Objective: This study aimed to investigate of cytotoxic activity of extracts that were obtained from Chelidonium Majus; Berberis sp.; Thalictrum foetidum containing various alkaloids on selected cancer cell lines. The aim was also The quantification of selected alkaloids in The investigated extracts by HPLC. Methods: The analysis of alkaloids contents were performed while using HPLC in reversed phase (RP) mode using Polar RP column and mobile phase containing acetonitrile, water, and ionic liquid. The cytotoxic effect of The tested plant extracts and respective alkaloids’ standards were examined while using human pharyngeal squamous carcinoma cells (FaDu), human tongue squamous carcinoma cells (SCC-25), human breast adenocarcinoma cell line (MCF-7), and human triple-negative breast adenocarcinoma cell line (MDA-MB-231). Conclusion: All of The investigated plant extracts possess cytotoxic activity against cancer cell lines: FaDu, SCC-25, MCF-7, and MDA-MB-231. The highest cytotoxic activity against FaDu and MDA-MB-231 cells was observed for Chelidonium majus root extract, while the highest cytotoxic activity against SCC-25 and MCF-7 cells was estimated for The Thalictrum foetidum root extract. There obtained significant differences in The cytotoxic activity of extracts that were obtained from The roots and herbs of Chelidonium majus and Thalictrum foetidum. Based on these results, investigated plant extracts can be recommended for further investigations of anticancer activity.

New anti-Alzheimer drugs from biodiversity: The role of the natural acetylcholinesterase inhibitors

Alzheimer’s disease (AD) is a progressive neurodegenerative pathology with severe economic and social impact. There is currently no cure, although cholinesterase inhibitors provide effective temporary relief of symptoms in some patients. Nowadays, drug research and development are based on the cholinergic hypothesis that supports the cognition improvement by regulation of the synthesis and release of acetylcholine in the brain. There are only four commercial medicines approved for treatment of AD, and natural products have played an important alternative role in the research for new acetylcholinesterase inhibitors, as exemplified through the discovery of galantamine. This profile conducts us to give in this paper an overview relating the several classes of natural products with anti-cholinesterasic activity as potential templates to the design of new selective and powerful anti-Alzheimer drugs.
