6β-Naltrexol-d 3

6?-Naltrexol D3 is a synthetic derivative of naltrexone, a medication that is used to treat alcohol and opioid addiction. It is labeled as a "D3" compound, indicating that it has three deuterium atoms substituted for three hydrogen atoms in its molecular structure. This modification is intended to improve the accuracy and precision of analytical measurements of the compound. The main mechanism of action of 6?-Naltrexol D3 is the blockade of opioid receptors in the brain, which reduces the rewarding effects of opioids and alcohol. This effect is thought to be mediated by the binding of the compound to the mu opioid receptor, which is responsible for the pleasurable sensations associated with opioid use. In addition, 6?-Naltrexol D3 may also have activity at other opioid receptors, such as kappa and delta, which are involved in pain perception and mood regulation. The chemical formula of 6?-Naltrexol D3 is C20H20D3NO4, and its molecular weight is 343.45 g/mol. It is a white to off-white powder that is soluble in water and ethanol. The compound is typically supplied as a stable isotope-labeled standard for use in pharmacokinetic studies and drug testing. Its purity and identity can be confirmed using various analytical techniques, such as high-performance liquid chromatography (HPLC), mass spectrometry (MS), and nuclear magnetic resonance (NMR) spectroscopy. Overall, 6?-Naltrexol D3 is a valuable tool for investigating the pharmacology and metabolism of naltrexone and related compounds. Its use in preclinical and clinical research may lead to the development of more effective treatments for substance use disorders and other conditions involving opioid receptor dysfunction.
