Background: Numerous molecules in Papaveraceae family display interesting cytotoxic activities against tumor cell lines in vitro and hints of anticancer activities in vivo have been reported in a few cases. Objective: Numerous molecules in this family display interesting cytotoxic activities against tumor cell lines in vitro and hints of anticancer activities in vivo have been reported in a fe...
BACKGROUND AND AIMS Previous measurements of conifer alkaloids have revealed significant variation attributable to many sources, environmental and genetic. The present study takes a complementary and intensive, common garden approach to examine genetic variation in Pinus ponderosa var. ponderosa alkaloid production. Additionally, this study investigates the potential trade-off between seedling ...
The first total synthesis of the pyrrolo[2,3- c ]quinoline alkaloid trigonoine B ( 1 ) was accomplished via a six-step sequence involving construction an N -substituted 4-aminopyrrolo[2,3- framework electrocyclization 2-(pyrrol-3-yl)benzene containing carbodiimide moiety as 2-azahexatriene system. employed afforded in 9.2% overall yield. described route could be for preparation various 4-aminop...
Background and objectives: The seedsof Sophora alopecuroides L. var. alopecuroides may benefit treatment of opioid dependence. Therefore, the plant alkaloid composition, toxicity and effects on morphine withdrawal were studied. Methods: The alkaloid composition was determined by GC and GC/MS analysis. Mice were made dependent by morphine injec...
