Panthenol
In cosmetics, panthenol (also called pantothenol) is a humectant, emollient, and moisturizer. It binds to hair follicles readily and is a frequent component of shampoos and hair conditioners (in concentrations of 0.1-1\\\%). It coats the hair and seals its surface, lubricating follicles and making strands appear shiny. Panthenol (specifically D-panthenol or dexpanthenol) is the alcohol analog of pantothenic acid (vitamin B5), and is thus the provitamin of B5. In organisms, it is quickly oxidized into pantothenate. Panthenol is a viscous transparent liquid at room temperature, but salts of pantothenic acid (for example sodium pantothenate) are powders (typically white). It is very soluble in water, alcohol, and propylene glycol, soluble in ether and chloroform, and only slightly soluble in glycerin.

Diethylpropion
Diethylpropion is only found in individuals that have used or taken this drug. It is a appetite depressant considered to produce less central nervous system disturbance than most drugs in this therapeutic category. It is also considered to be among the safest for patients with hypertension. (From AMA Drug Evaluations Annual, 1994, p2290)Diethylpropion is an amphetamine that stimulates neurons to release or maintain high levels of a particular group of neurotransmitters known as catecholamines; these include dopamine and norepinephrine. High levels of these catecholamines tend to suppress hunger signals and appetite. Diethylpropion (through catecholamine elevation) may also indirectly affect leptin levels in the brain. It is theorized that diethylpropion can raise levels of leptin which signal satiety. It is also theorized that increased levels of the catecholamines are partially responsible for halting another chemical messenger known as neuropeptide Y. This peptide initiates eating, decreases energy expenditure, and increases fat storage.

3-Hydroxy-N6,N6,N6-trimethyl-L-lysine
3-Hydroxy-N6,N6,N6-trimethyl-L-lysine is found within the Lysine degration pathway; it is the byproduct of trimethyllysine dioxygenase (EC 1.14.11.8) which converts N6-Hydroxy-trimethyl-lysine to Glycine and 4-Trimethyl-ammoniobutanal. Because carnitine is the final product of the Lysine degration pathway, this compound is often associated with carnitine defiency disorders. (PMID: 16707092) The compound is also a byproduct of glycine hydroxymethyltransferase (EC 2.1.2.1) and Lyases (EC 4.1.2.-).

Phenformin
A biguanide hypoglycemic agent with actions and uses similar to those of metformin. Although it is generally considered to be associated with an unacceptably high incidence of lactic acidosis, often fatal, it is still available in some countries.

N-Desthienylethyl-rotigotine
N-Desthienylethyl-rotigotine is a metabolite of rotigotine. Rotigotine (Neupro) is a non-ergoline dopamine agonist indicated for the treatment of Parkinsons disease (PD) and restless legs syndrome (RLS) in Europe and the United States. It is formulated as a once-daily transdermal patch which provides a slow and constant supply of the drug over the course of 24 hours. Like other dopamine agonists, rotigotine has been shown to possess antidepressant effects and may be useful in the treatment of depression as well. (Wikipedia)

propanolamine
Propanolamine, also known as 3-amino-1-propanol, is a member of the class of compounds known as 1,3-aminoalcohols. 1,3-aminoalcohols are organic compounds containing an alkyl chain with an amine group bound to the C1 atom and an alcohol group bound to the C3 atom. Propanolamine is soluble (in water) and an extremely weak acidic compound (based on its pKa). Propanolamine can be found in french plantain, which makes propanolamine a potential biomarker for the consumption of this food product. Propanolamines include: Acebutolol Atenolol Betaxolol Bisoprolol Metoprolol Nadolol Penbutolol Phenylpropanolamine Pindolol Practolol Propranolol Ritodrine Timolol .
