Conotoxins are highly constrained peptide toxins that exhibit pharmaceutically relevant biological activities. We herein report the extent of absorption and profile of distribution of a native alpha-conotoxin, MII and a lipophilic analogue of MII (N-LaaMII) after intravenous (iv) and oral administration to male Sprague-Dawley rats. N-LaaMII is formed by(More)
Leu-enkephalin is an endogenous pain modulating opioid pentapeptide. Its development as a potential pharmaceutic has been hampered by poor membrane permeability and susceptibility to enzymatic degradation. The addition of an unnatural amino acid containing a lipidic side chain at the N-terminus and the modification of the C-terminus to a carboxyamide was(More)
