Substances produced in the body that act like those found in the cannabis plant help preserve bone density, according to researchers at the Hebrew University of Jerusalem.
Based on this finding, a prototype for a new drug to prevent osteoporosis (loss of bone density) without any psychoactive side effects has already been developed.
Substances made in the body called endocannabinoids are composed mainly of fatty acids which were discovered during the last 15 years. These materials, which are produced mainly in the brain, are present also in the bone and other tissues and have similar effects
to those of the active components in hashish and marijuana, produced from the cannabis plant.
These substances bind to and activate two receptors, CB1 and CB2. The first is found in the nervous system and is responsible for the psychoactive effects of the active components in the cannabis plant and endocannanoids. The second receptor is found in the immune system. It is not known to be involved with psychoactive responses, and there has been little information about its physiological function.
The Hebrew University researchers discovered a high level of CB2 receptors in bone, and that this is required in order to preserve normal bone density. Together with their colleagues at the University of Bonn, Germany, Prof. Andreas Zimmer and Dr. Malia Karasek, they studied the skeletons of genetically engineered mice lacking the CB2 receptor. As they aged, these CB2-deprived mice developed severe osteoporosis, similar to that which appears in humans.
This indicates that substances that activate the CB2 receptor can be used as basis for the development of drugs for osteoporosis patients. Indeed, the Hebrew University researchers have developed a new synthetic compound, HU-308, which activates CB2 and slows the development of osteoporosis in mice.
This compound forms the basis for a cannabinoid-based, anti-osteoporotic type drug which has also been found to be free of any psychoactive side effects.
Osteoporosis is the most widespread degenerative disease in developed countries and can lead to multiple fractures, disability and complications, and even death.
