18-Methoxycoronaridine, a novel iboga alkaloid congener, reduces drug self-administration in animal models of addiction. Previously, we proposed that these effects are mediated by the ability of 18-methoxycoronaridine to inhibit nicotinic alpha3beta4 acetylcholine receptors. In an attempt to identify more potent 18-methoxycoronaridine analogs, we have(More)
The objective of this study was to evaluate the effects of supplementation of phytoecdysteroids (PEDS) extracted from Cyanotis arachnoidea on rumen fermentation, enzymes activity and microbial efficiency in a dual flow continuous-culture system. A single-factor experimental design was used with twelve fermenters in 4 groups with 3 replicates each.(More)
