N-Acetyltyrosine is an acetylated derivative of the amino acid L-tyrosine. Ordinary L-tyrosine is less stable and also less soluble in water, which may result in reduced bioavailability. Acetylation enhances the solubility and stability of certain amino acids. N-Acetyltyrosine is commonly used in place of tyrosine in parenteral nutrition. It converts to tyrosine and then can be used in neurotransmitter treatment as a precursor of cathecholamine. N-Acetyltyrosine supports brain function by supporting the synthesis of the catecholamines norepinephrine and dopamine (neurotransmitters). N-Acetyltyrosine supplements are used to improve memory and cognitive performance in humans while they are experiencing psychological stress.

Taurine is a semi-essential amino acid and is not incorporated into proteins. Taurine is considered conditionally essential because it cannot be synthesized by infants younger than 4-6 weeks, and it may not be adequately synthesized in patients receiving long-term parenteral nutrition and patients with short-term hypermetabolic conditions. In mammalian tissues, taurine is ubiquitous and is the most abundant free amino acid in the heart, retina, skeletal muscle, brain, and leukocytes. Taurin occurs naturally in fish and meat. The mean daily intake from omnivore diets was determined to be around 58 mg. Taurine is a component of energy drinks, with many contain 1000 mg per serving. In medicine, taurine supplementation demonstrated efficacy in relieving symptoms of heart failure, hepatitis, hypertension and psychotic disorder. Taurine exerts many physiological functions, including membrane stabilization, osmoregulation and cytoprotective effects, antioxidant and anti-inflammatory actions as well as modulation of intracellular calcium concentration and ion channel function. In addition taurine may control muscle metabolism and gene expression, through yet unclear mechanisms. The cellular and biochemical mechanisms mediating the actions of taurine are not fully known.

Monoethanolamine is both a primary amine and a primary alcohol. It is an olamine derivative. Monoethanolamine occurs in every cell in the human body as the head group of Phosphatidylethanolamine. Monoethanolamine is a component of glycosylphosphatidylinositol-anchored proteins, which are essential for viability. Other sources of monoethanolamine or phosphoethanolamine in the human body are the degradation of sphingosine phosphate by sphingosine phosphate lyase and the degradation of the endocannabinoid anandamide by the fatty acid amine hydrolase. Monoethanolamine stimulates the rapid growth of mammalian cells in culture. Monoethanolamine has a cardioprotective role against ischemia/reperfusion injury via activation of the transcription factor STAT-3. Monoethanolamine is a chemical intermediate in the manufacture of cosmetics, surface-active agents, emulsifiers, pharmaceuticals, and plasticizing agents.

Adenine is a nucleobase (a purine derivative). Its derivatives have a variety of roles in biochemistry including cellular respiration, in the form of both the energy-rich adenosine triphosphate (ATP) and the cofactors nicotinamide adenine dinucleotide (NAD) and flavin adenine dinucleotide (FAD). It also has functions in protein synthesis and as a chemical component of DNA and RNA. The shape of adenine is complementary to either thymine in DNA or uracil in RNA

L-serineThe is a non-essential amino acid. L-serine and the products of its metabolism have been recognized not only to be essential for cell proliferation, but also to be necessary for specific functions in the central nervous system. The findings of altered levels of serine and glycine in patients with psychiatric disorders and the severe neurological abnormalities in patients with defects of L-serine synthesis underscore the importance of L-serine in brain development and function. L-serine supplementation is in trials for the treatment of several CNS diseases such as Alzheimer's disease, Hereditary sensory and autonomic neuropathy type 1 and Amyotrophic Lateral Sclerosis

Proline (L-Proline) is one of the twenty amino acids used in living organisms as the building blocks of proteins. Proline is a non-essential amino acid that is synthesized from glutamic acid. It is an essential component of collagen and is important for proper functioning of joints and tendons. Proline is used in pharmaceuticals as an excipient and as an active substance in nutritional supplements. Proline is not commonly used in pharmaceuticals as an excipient. It is approved for use in Privigen (IVIg) and Hizentra (SCIg) solution for injection as a stabiliser for IgG. Proline is also contained in low amounts in several vaccines, e.g. Havrix 720 Kinder (Hepatitis A).

Malic acid is a tart-tasting organic dicarboxylic acid that contributes to the taste of many sour or tart foods such as apples. Sodium Malate is the sodium salt of Malic Acid. Malic Acid and Sodium Malate can be found in a wide range of cosmetics and personal care products. Sodium Malate functions as a skin conditioning agent-humectant. As a food additive, Sodium Malate has the E number E350. Sodium Malate has demonstrated protective effect on cisplatin-induced toxicity in mice. Sodium malate could become a useful agent for the reduction of CDDP-induced toxicity, particularly nephrotoxicity and hepatotoxicity.

Octopamine is an organic chemical closely related to norepinephrine. In many types of invertebrates it functions as a neurotransmitter. Octopamine is known to exert adrenergic effects in mammals although specific octopamine receptors have been cloned only in invertebrates. It has been shown that octopamine can stimulate alpha(2)-adrenoceptors (ARs) in Chinese hamster ovary cells transfected with human alpha(2)-ARs. Octopamine stimulates lipolysis through beta(3)-rather than beta(1)-or beta(2)-AR activation in white adipocytes from different mammalian species. Octopamine activates only beta(3)-ARs and is devoid of alpha(2)-adrenergic agonism. Thus, octopamine could be considered as an endogenous selective beta(3)-AR agonist. In humans Octopamine is a trace amine found endogenously in the human brain where it interacts with signalling of catecholamines; it is structurally similar to synephrine and tyramine, being a metabolite of the latter (via dopamine β-hydroxylase) and substrate for the synthesis of the former (via phenethanolamine N-methyltransferase[3]) while being perhaps the closest in structure to noradrenaline. Octopamine is found in the bitter orange similar to many biogenic amines related to L-tyrosine that are used as dietary supplements, this includes synephrine and hordenine. p-Octopamine HCl (Norphen) was studied in the late 1960’s and 1970’s as a drug for the treatment of hypotensive regulatory and circulatory disorders. Octopamine was used as a nootropic. All optical isomers (enantiomers) of octopamine are on the World Anti-Doping Agency (WADA) 2014 list of substances prohibited in competition.

17α-Hydroxyprogesterone (17α-OHP), or hydroxyprogesterone (OHP), also known as 17α-hydroxypregn-4-ene-3, 20-dione is used under the brand name Gestageno, and has been marketed for clinical use in Argentina. It was indicated for female infertility, hypertrichosis, menstrual disorders, premature labour, threatened or recurrent miscarriage. It is used to properly regulate the menstrual cycle and treat unusual stopping of the menstrual periods (amenorrhea). To help a pregnancy occur during egg donor or infertility procedures in women who do not produce enough progesterone. To prevent estrogen from thickening the lining of the uterus (endometrial hyperplasia) in women around menopause who are being treated with estrogen for ovarian hormone therapy (OHT). To treat a condition called endometriosis, to help prevent endometrial hyperplasia, or to treat unusual and heavy bleeding of the uterus (dysfunctional uterine bleeding) by starting or stopping the menstrual cycle. 17α-OHP is an agonist of the progesterone receptor (PR) similarly to progesterone. In addition, it is an antagonist of the mineralocorticoid receptor (MR) as well as a partial agonist of the glucocorticoid receptor (GR), albeit with very low potency (EC50 >100-fold less relative to cortisol) at the latter site, also similarly to progesterone.
