Revision as of 18:51, 17 October 2014

Opium Derivatives

Opium Alkaloids

Thebaine - 6,14 Dimethoxy version of Oxymorphone. Stimulant rather than an analgesic.
Narceine - Bitter, Crystalline, formerly used as a substitute for Morphine.
Noscapine - Acts on the Sigma receptor. Non painkilling. Used commonly in Antitussives. Blocks Bradykinine B-2 receptors in Stroke patients.


Alkaloid Salt Mixtures

Pantopon - Preparation of all alkaloids present in opium without plant matter. Injectable and slightly less potent than Morphine.


Morphine Family

6-MDDM - 80x Morphine, has a faster onset and less body load then the prior.
Azidomorphine - 40x Morphine, has a high affinity for μ.
Hydromorphinol - Derivative of Morphine, yet more potent, with a steeper-dose-response curve and a longer half life. Scripted in Sweden.
Methyldesorphin - 15x Morphine. Is found in some mixtures of Krokodil.
MR-2096 - Oxymorphone analogue that is roughly the same potency.
N-Phenethylnormorphine - 8-14x Morphine.
RAM-378 - N-Phenethyl analogue of Hydromorphinol. It is probably more potent as a result.

3,6 Morphine Diesters

Diacetyldihydromorphine - Occasionally used as an alternative to diamorphine, of which it is faster acting, longer lasting and has less side effects such as euphoria and addiction. However it is equipotent with Morphine.
Dipropanoylmorphine - Ester of Morphine used to treat severe pain. Rarely used but considered to be safer and less addictive than Morphine. As such carries less side effects, such as euphoria. Slower acting, longer lasting and slightly more potent than Morphine.
Nicomorphone - 2-3x Morphine and commonly prescribed in German speaking countries.

Codeine-Dionine Family

Heterocodeine - Reverse isomerEach of two or more compounds with the same formula but a different arrangement of atoms in the molecule and different properties. of codeine. 6x Morphine, while Codeine is a prodrug, Heterocodeine is a direct agonistA substance that initiates a physiological response when combined with a receptor..
Myrophine - Acts as a prodrug to Morphine. Has a slow onset and longer duration, but reduced potency. Does NOT produce addiction or dependence regardless of dose.
Acetyldihydrocodeine - Used in Germany. Close relative of Thebacon, where only the 6-7 cond is unsaturated. 6-Acetyl derivative of Dihydrocodeine. Metabolizes into Dihydromorphine. Higher lipophilicity than codeine. Would probably be more potent and longer lasting as a result. Higher oral BA than Codeine.

Morphinones and Morphols

14-Cinnamoyloxycodeinone - 100x Morphine.
14-Methoxymetopon - 500x Morphine. Can be up to one million times Morphine if injected into the spine.
14-Phenylpropoxymetopon - 2000x potency of Morphine. When injected into the spine up to one million times Morphine. 14-Methoxymetopon has a ceiling effect on respiratory depression, but the above has been left untested.
3-Acetyloxymorphone - Acetylated analogue of Oxymorphone.
7-Spiroindanyloxymorphone - Odd Oxymorphone analogue that is selective at dopamineA neurotransmitter associated with movement, attention, learning, and the brain’s pleasure and reward system..
Acetylmorphone - Acetoxy version of Hydromorphone, has a higher bioavailabilityThe fraction of an administered dose that is absorbed into a living system. as a result.
Chloroxymorphamine - Derivative of Oxymorphone and irreversible full agonistA substance that initiates a physiological response when combined with a receptor..

Ro64-6198 - Potent, selective ORL-1 agonistA substance that initiates a physiological response when combined with a receptor. with 100x selectivity over others. In rats produced anxiolytic but no anticonvulsant effects. Impairs short term memory & increases appetite. Reduces analgesic effects of Morphine but does not prevent tolerance. In primates it showed analgesic behaviour without respiratory depression.

Enkephalin Potease Inhibitors

RB-101*** - Inhibits enzymes responsible for breaking down enkephalin (regulates nociceptin). Weak μ & δ affinity and slight σ1. Potentiates opioids, stops withdrawal symptoms, no addiction potential, produces no respiratory depression. Also exerts very potent antidepressant and anxiolytic effects. Not orallyRoute of administration in which the subject swallows a substance. active so analogues vv were developed.
