Dehydrosafynol
Dehydrosafynol, also known as (2r,11e)-11-tridecene-3,5,7,9-tetrayne-1,2-diol, is a member of the class of compounds known as long-chain fatty alcohols. Long-chain fatty alcohols are fatty alcohols that have an aliphatic tail of 13 to 21 carbon atoms. Thus, dehydrosafynol is considered to be a fatty alcohol lipid molecule. Dehydrosafynol is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Dehydrosafynol can be found in safflower, which makes dehydrosafynol a potential biomarker for the consumption of this food product.
5-Acetylamino-6-amino-3-methyluracil
5-Acetylamino-6-amino-3-methyluracil (AAMU) is one of caffeine major metabolites. Analysis of caffeine and its metabolites is of interest with respect to caffeine exposure, for kinetic and metabolism studies and for opportunistic in vivo estimation of drug metabolizing enzyme activity in humans and animals. Urinary caffeine metabolite ratios are used in humans to assess the activity of cytochrome P450 1A2 (CYP1A2), xanthine oxidase and N-acetyltransferase 2 (NAT2), which are involved in the activation or detoxification of various xenobiotic compounds, including carcinogens. Investigating the activity of these enzymes is of clinical relevance for assessing intra- and inter-individual differences in NAT2- and CYP1A2-mediated drug metabolism, and for evaluating the risk of developing specific exposure-related diseases.

Guaifenesin
Guaifenesin is a member of methoxybenzenes. Guaifenesin possesses a storied history, having been originally formally approved by the US FDA in 1952 and continues to be one of very few - if not perhaps the only drug that is readily available and used as an expectorant. Since that time the agent has been a combination component of various prescription and non-prescription over-the-counter cough and cold products and is currently a widely available over-the-counter generic medication. Although it is principally believed that guaifenesin elicits an action to facilitate productive cough to manage chest congestion, it is not known whether the agent can reliably mitigate coughing. Regardless, on March 1, 2007, the FDA received a petition asking the FDA to notify the public that some antitussives, expectorants, decongestants, antihistamines, and cough/cold combinations are not known to be safe and effective in children under the age of 6 years. After the negotiation between FDA and major manufacturers, a voluntary transition of labels for not using guaifenesin in children under the age of 4 years was endorsed by FDA in 2008. Furthermore, there has also been contemporary research to suggest that guaifenesin possesses and is capable of demonstrating anticonvulsant and muscle relaxant effects to some degree possibly by acting as an NMDA receptor antagonist. Guaifenesin is an Expectorant. The physiologic effect of guaifenesin is by means of Decreased Respiratory Secretion Viscosity, and Increased Respiratory Secretions. Guaifenesin is a natural product found in Plectranthus with data available. Guaifenesin is a glyceryl guaiacolate with expectorant effects. Guaifenesin increases respiratory tract mucus secretions, acts as an irritant to gastric vagal receptors and recruits efferent parasympathetic reflexes that cause glandular exocytosis. This agent reduces the viscosity of mucus secretion by reducing adhesiveness and surface tension as well as increasing hydration of mucus. Guaifenesin promotes the efficiency of the mucociliary mechanism important in removing accumulated secretions from the upper and lower airway. An expectorant that also has some muscle relaxing action. It is used in many cough preparations. [PubChem] An expectorant that also has some muscle relaxing action. It is used in many cough preparations.

View More ... Guaifenesin (International Noproprietary Name) or guaiphenesin (former British Approved Name) is an expectorant drug usually taken orally to assist the expectoration (bringing up) of phlegm from the airways in acute respiratory tract infections. It is a common ingredient in many over-the-counter cough/cold medications. Guaifenesin is also used in the experimental guaifenesin protocol in the treatment of fibromyalgia. It was first approved by the Food and Drug Administration (FDA) in 1952. Guaifenesin works by drawing water into the bronchi. The water both thins mucus and lubricates the airway, facilitating the removal of mucus by coughing.
