| 摘要 |
The present invention provides composition of matter for and methods of treating pain and drug abuse using novel chimeric hybrid molecules containing an opioid moiety of chemically modified morphine ( 3 ) that binds to and activates the human mu (mu) opioid receptor, with the opioid moiety linked through a novel linker-hinge ( 4 ) to a substance P peptide fragment moiety ( 5 ) that binds to and activates the human substance P receptor. The hybrid alkaloid/peptide chimeric molecules produce clinically efficacious opioid analgesia with little or no development of opioid tolerance or formation of opioid dependence. The hybrid alkaloid/peptide analgesics may be administered intrathecally, systemically or orally.
