英文摘要
At the present time there is no medication available to patients with
moderate to severe pain with the following characteristics: No physical
drug dependence liability, little or no oral or overdose lethality, little
or no effects on respiratory centers, orally potent, and long acting. In
this project we propose to prepare and pharamacologically evaluate six
nitrogen analogs of Delta9-Tetrahydrocannabinols (THC's) including two
water soluble derivatives. These compounds are designed and modeled after
the active principal of Cannabis Sativa because THC's are relatively unique
among drugs acting on the central nervous system (CNS). Natural products
THC's are unique because (a) they contain no elemental nitrogen in their
molecular structures; (b) they are not lethal to laboratory animals when
administered orally; (c) they show little or no respiratory effects; and
(d) though they exhibit marked CNS and some cardiovascular effects
(euphoria and tachycardia), neither cannabis nor THC's have ever been
reported to result in physical addiction or lethality, despite centuries of
use and abuse of the natural product. Preliminary results from these
laboratories (10 patients) with a related nitrogen analog in a double blind
crossover relative potency assay in post-operative pain due to cancer, has
already shown pain relief which is six times the potency of codeine.
Following twenty years of research on the general chemistry, pharmacology
and structure activity of new chemical substances derived from the
cannabinoid nucleus, it is the specific aim of this project to (1)
synthesize and study the detailed anti-nociceptive, pharmacological profile
of four carefully selected nitrogen analogs having phenylethyl amine
chemical moities found in narcotic-like analgesics, and (2) choose one of
these for follow-on, in-depth, Phase II funding and study as a potentially
marketable unique product for use in post-operative pain, arthritic pain,
dental pain and other pain models for the aged.
