Biological Activities
Compounds
Euphorbia canariensis serves as a natural source for the isolation of DBI, a specific ingol derivative. Scientific analysis has focused on how this compound influences vascular responses, particularly within rabbit basilar and carotid arteries. Research indicates that DBI induces concentration-dependent contractions that operate through mechanisms independent of extracellular calcium. These contractions appear to involve the participation of both protein kinase C and calmodulin in the physiological process. Furthermore, the study reveals that DBI can also induce relaxation in basilar arteries through pathways that do not rely on nitric oxide or prostacyclin.
Conditions
Euphorbia canariensis produces an ingol derivative known as DBI that significantly affects the isometric tension of isolated rabbit basilar and carotid arteries. At resting tension, this derivative induces a concentration-dependent contraction in both types of arteries through a mechanism independent of extracellular calcium. The contraction process involves the participation of both protein kinase C and calmodulin. In pre-contracted basilar arteries, DBI facilitates a concentration-dependent relaxation that does not rely on nitric oxide or prostacyclin. Conversely, in carotid arteries with active tone, DBI induces further contractions that can be partially counteracted by prostacyclin.
