Goniomitine: An Overview on the Chemistry of This Indole Alkaloid

Pharmacological properties of some 3-substituted indole derivatives, a concise overview

Indole is a nitrogen-containing heterocycle. It is a very important motif in agriculture and pharmacy. Many compounds containing indole moiety has been isolated form nature. It is also an important part in natural alkaloids. Tryptophan is an amino acid which posses indole. 3-Sustituted indoles are the main group of its derivatives. Because the wide-spread application of 3-substituted indolic co...

Indole alkaloids synthesis via a selective cyclization of aminocyclopropanes.

The continuous progress in medicinal chemistry requires more versatile synthetic strategies for the generation of large libraries of active compounds and their analogues. As a result, the research for new effective cyclization and cycloaddition reactions is an essential task in organic chemistry. In 2008 we developed the first catalytic formal homo-Nazarov reaction starting from activated cycl...

Chemistry and biology of monoterpene indole alkaloid biosynthesis.

[Development of new synthetic methods and their application to synthesis of useful compounds].

Development of novel synthetic methodologies and their application to synthesis of natural products are described. The first topic is about an extension of the scope of our indole synthesis by radical cyclization of o-alkenylphenyl isocyanides. By utilizing this methodology and nitrogenzenesulfonamide chemistry, an efficient total synthesis of hexacyclic aspidosperma indole alkaloid, aspidophyt...

Mitotic Block of Human Blood Cells by Vinca herbacea, Catharanthus roseus and Colchicine Alkaloids

Catharanthus roseus (L.) G.Don is a plant which produces anticancer and anti-mitotic indole alkaloids. Colchicine is an anti-mitotic drug. Anti-mitotic effects of Vinca herbacea Waldst. & Kit. indole alkaloids is unknown. The study were evaluated the antimitotic effect of alkaloids of V. herbacea, Catharanthus roseus andcolchicineon mitosis and microtubule arrangement of human blood cells. In t...
