We have studied the effects of cleistanthin A and cleistanthin B, phytoconstituents isolated from the leaves of Cleistanthus collinus Roxb. (Euphorbiaceae), on blood pressure, electrocardiogram, and barium chloride-induced arrhythmia in Wistar rats. The two compounds were isolated by column
OBJECTIVE
To determine the biodistribution properties of cleistanthin A and cleistanthin B in rodents using magnetic resonance imaging (MRI).
METHODS
Cleistanthins A and B, constituents of Cleistanthus collinus Roxb., were labelled with gadolinium (Gd(3+)) directly and injected into normal and
OBJECTIVE
To investigate the toxicological effects of cleistanthin A and cleistanthin B using sub-chronic toxicity testing in rodents.
METHODS
Cleistanthins A and B were isolated from the leaves of Cleistanthus collinus. Both the compounds were administered orally for 90 days at the concentration of
OBJECTIVE
To investigate the involvement of alpha adrenergic receptors in hypotension induced by cleistanthin A and cleistanthin B.
METHODS
Cleistanthins A and B were isolated from the leaves of Cleistanthus collinus using a column chromatographic method and purified. Structures were confirmed by
BACKGROUND
Cleistanthins A and B are isolated compounds from the leaves of Cleistanthus collinus Roxb (Euphorbiaceae). This plant is poisonous in nature which causes cardiovascular abnormalities such as hypotension, nonspecific ST-T changes and QTc prolongation. The biological activity predictions
