Extraction and Exploration of a Novel Selective Kappa Opioid Ligand.Salvinorin A is a neoclerodane diterpene di·ter·pene n. Any of a class of terpenes containing 20 carbon atoms and 4 branched methyl groups. diterpene highly irritant plant diterpenoid esters, e.g. daphnane, tigliane, ingemane. and is the active component in plant, Salvia divinorum. This compound has been shown to be a potent kappa opioid agonist in vitro and in vivo. At this moment, salvinorin A is the only known naturally occurring nonnitrogenous kappa opioid selective ligand. Its selectivity and activity at the kappa opioid receptor The κ-Opioid receptors are a class of opioid receptors with dynorphins as the primary endogenous ligands, and ketazocine as a potent selective exogenous ligand. There are three variants: κ1, κ2, and κ3. makes it a possible novel treatment for substance abuse. This is because kappa opioid agonists have been shown to antagonize the effects of central nervous stimulants by regulating the effect of dopamine in the brain; thereby, diminishing the stimulating effects of cocaine. In addition, kappa opioid agonists also have analgesic properties, so salvinorin A could also be a potential analgesia analgesia /an·al·ge·sia/ (an?al-je´ze-ah) 1. absence of sensibility to pain. 2. the relief of pain without loss of consciousness. . As part of our ongoing research, we have successfully optimized a procedure to extract salvinorin A from the leaves of Salvia divinorum; we are also exploring analogues of Salvinorin A using structure-activity relationship studies.

The first faculty offered instruction at the University in March 1855 to students in the Old Mechanics Building, situated where Seashore Hall is now. In September 1855, the student body numbered 124, of which, 41 were women. and Department of Agriculture and Natural Sciences, Lincoln University. |
