Oxycodone

(1S,5R,13R,17S)-17-hydroxy-10-methoxy-4-methyl-12-oxa-4-azapentacyclo[9.6.1.0^{1,13}.0^{5,17}.0^{7,18}]octadeca-7(18),8,10-trien-14-one

Oxycodone is only found in individuals that have used or taken this drug. It is a semisynthetic derivative of codeine that acts as a narcotic analgesic more potent and addicting than codeine. [PubChem]Oxycodone acts as a weak agonist at mu, kappa, and delta opioid receptors within the central nervous system (CNS). Oxycodone primarily affects mu-type opioid receptors, which are coupled with G-protein receptors and function as modulators, both positive and negative, of synaptic transmission via G-proteins that activate effector proteins. Binding of the opiate stimulates the exchange of GTP for GDP on the G-protein complex. As the effector system is adenylate cyclase and cAMP located at the inner surface of the plasma membrane, opioids decrease intracellular cAMP by inhibiting adenylate cyclase. Subsequently, the release of nociceptive neurotransmitters such as substance P, GABA, dopamine, acetylcholine, and noradrenaline is inhibited. Opioids such as oxycodone also inhibit the release of vasopressin, somatostatin, insulin, and glucagon. Opioids close N-type voltage-operated calcium channels (kappa-receptor agonist) and open calcium-dependent inwardly rectifying potassium channels (mu and delta receptor agonist). This results in hyperpolarization and reduced neuronal excitability.

It is a benzazepine alkaloid, a benzazepine alkaloid fundamental parent, an organic heteropentacyclic compound, an enol ether, a cyclic acetal, a secondary alcohol and a tertiary amino compound. Omacetaxine is a semisynthetic cephataxine that acts as a protein translation inhibitor and is used to treated chronic myeloid leukemia that is resistant to tyrosine kinase receptor antagonists. Omacetaxine is associated with a low rate of serum enzyme elevation during therapy, but has not been linked to cases of clinically apparent liver injury with jaundice. Cephalotaxine is a natural product found in Cephalotaxus hainanensis, Cephalotaxus harringtonia, and other organisms with data available. Omacetaxine is a protein translation inhibitor and cytotoxic plant alkaloid homoharringtonine isolated from the evergreen tree Cephalotaxus, with potential antineoplastic activity. Although the exact mechanism of action has not been fully elucidated, upon administration, omacetaxine targets and binds to the 80S ribosome in eukaryotic cells and inhibits protein synthesis by interfering with chain elongation. This reduces levels of certain oncoproteins and anti-apoptotic proteins. Semisynthetic derivative of harringtonine that acts as a protein synthesis inhibitor and induces APOPTOSIS in tumor cells. It is used in the treatment of MYELOID LEUKEMIA, CHRONIC. See also: Omacetaxine Mepesuccinate (active moiety of).
