cinchona officinalis/항진균제

An efficient synthesis of highly functionalized chiral β-amino ester derivatives containing benzothiophene and benzothiazole moieties is developed by a Mannich-type reaction using a cinchona alkaloid-derived thiourea catalyst. The desired products were obtained in good yields and high

Homeopathy is a therapeutic method based on the application of similia principle, utilizing ultra-low doses of medicinal substances made from natural products. The present study has been designed to evaluate the efficacy of Cinchona officinalis (Chin.) 30C and Chelidonium majus (Chel.) 30C in

It has been shown with one strain of pneumococcus (Type 1, Neufeld), that hydroquinine chloroacetanilide (C 29), hydroquinine p-chloroacetylaminophenol hydrochloride (C 36), hydroquinine m-chloroacetylaminophenol hydrochloride (C 40), and hyroquinine 4-chloroacetylaminopyrocathecol hydrochloride (C

The blood schizontocidal activity of the four main Cinchona alkaloids against Plasmodium falciparum was compared in 46 fresh parasite isolates, using an in-vitro test measuring the drug-specific inhibition of schizont maturation. The studies were conducted in June-August 2001 at Mae Sot,

Δ2-Pyrazolines are of significant medicinal and synthetic interest due to their therapeutic properties and utility in the synthesis of 1,3-diamines, yet few asymmetric methods exist to prepare them. An unprecedented highly enantioselective organocatalytic synthesis of 2-pyrazolines was achieved

TRAF6 is highly expressed in many tumors and plays an important role in the immune system. The aim of this study is to confirm anti-tumor activities of all naturally occurring Cinchona alkaloids that have been screened using computational docking program, and to validate the accuracy and specificity

Malaria is one of the life-threatening parasitic diseases that is endemic in tropical areas. The increased prevalence of malaria due to drug resistance leads to a high incidence of mortality. Drug discovery based on natural products and secondary metabolites is considered as alternative approaches

On of the most compelling sagas in the history of medicine and therapeutics is the emergence of the Peruvian bark (Cinchona) and also of the pharmacologically active substance derived from it, quinine. Its discovery involved exploration, exploitation and secrecy, and it came, in the nineteenth

The increasingly diverse U.S. immigrant populations and the growing use of medicinal herbs create a need for health care professionals to expand their knowledge in this area. This is a review of tropical plants, Annona Muricata, Artemisia absinthium, Cinchona officinalis, Illicium verum, Momordica
