Medicinal Properties of Cinchona Alkaloids - A Brief Review

Asian Journal of Research in Pharmaceutical Sciences, 2021
Cinchona which belongs to family Rubiaceae, got its importance from the centuries because of its anti- malarial activity. Alkaloids present in this herb, Quinine, Chichonine, Quinidine and Cinchonidine are the main, but percentage may vary in species ...

The cinchona alkaloids and the aminoquinolines

, 2020
The bark of the cinchona tree was first employed to treat malaria in Europe during the 15th century. Its active ingredients are natural products that are collectively known as the cinchona alkaloids and include quinine.

Synthesis of chiral polyurethanes of cinchona alkaloids for the enantioselective synthesis in asymmetric catalysis

Catalysis communications, 2019
Chiral polyurethanes of cinchona alkaloid were synthesized via repetitive Mizoroki-Heck (MH) coupling reaction. The Pd-catalyzed polycondensation of cinchona urethane dimers and aromatic diiodides afforded the chiral polyurethanes.

Conformational spaces of Cinchona alkaloids

Chirality, 2003
AbstractA systematic and comprehensive study of the conformational spaces of the Cinchona alkaloids quinine, quinidine, cinchonine, cinchonidine, epiquinine, epiquinidine, epicinchonine, and epicinchonidine using the semiempirical PM3 method is described.
