Thioctic acid also known as alpha-lipoic acid is a dietary supplement, which is a common ingredient in OTC (over-the-counter) multivitamin formulas and anti-aging supplements. Thioctic acid exists in both R- and S-enantiomeric forms, however, only R-form is essential as a cofactor in biological systems (the acid is coupled via an amide linkage to a lysine of several multienzyme complexes, such as the pyruvate dehydrogenase complex, the alpha-ketoglutarate dehydrogenase complex, the glycine cleavage system and the branched-chain oxo acid dehydrogenase complex). Most commercially available thioctic acid supplements are a mixture of both R and S enantiomers or R-form alone. Several studies have shown that the acid has beneficial effect on diabetes complications, cancer, glaucome, liver disease, etc. The mechanisms of thioctic acid is related to its antioxidant properties, metal chelator properties, however, those mechanisms need futher confirmation.

Borneol, a monoterpenoid alcohol, is a component of many essential oils. Barneol occurs in nature as a single enantiomer (d- or l-, depending on the oil type) or, less frequently, as the racemate. Several studies have proved the effectiveness of borneol. In Chinese medicines borneol has been used in relieving symptoms of anxiety, fatigue and insomnia; inducing anesthesia and analgesia to alleviate abdominal pain, wounds and burns; relieving rheumatic pain, hemorrhoids, skin diseases and ulcerations of the mouth, ears, eyes or nose; to treat sore throats and skin infections, and is mainly used to treat cardiovascular and cerebrovascular diseases. Borneol has a significant therapeutic effect on neuralgia. This compound is considered a GRAS approved by the FDA as food flavor. Additionally, borneol is a fragrance ingredient. GABAA, TRPV3, TRPM8 and TRPA1 have been identified as the molecular targets of borneol.

Creatinine is a product of metabolism of creatine phosphate, a molecule that serves as a rapidly mobilizable reserve of a brain and skeletal muscle. Creatinine is excreted by kidneys with little or no reabsorption. Serum creatinine is the most commonly used indicator of renal function.

An alkaloid found in opium but not closely related to the other opium alkaloids in its structure or pharmacological actions. Papaverine is a vasodilating agent. Papaverine is used for the treating certain conditions that are accompanied by smooth muscle spasms (eg, blood vessel, urinary, gallbladder, or intestinal spasm). Papaverine is a nonxanthine phosphodiesterase inhibitor for the relief of cerebral and peripheral ischemia associated with arterial spasm and myocardial ischemia complicated by arrhythmias. The main actions of Papaverine are exerted on cardiac and smooth muscle. Like qathidine, Papaverine acts directly on the heart muscle to depress conduction and prolong the refractory period. Papaverine relaxes various smooth muscles. This relaxation may be prominent if spasm exists. The muscle cell is not paralyzed by Papaverine and still responds to drugs and other stimuli causing contraction. The antispasmodic effect is a direct one, and unrelated to muscle innervation. Papaverine is practically devoid of effects on the central nervous system. Papaverine relaxes the smooth musculature of the larger blood vessels, especially coronary, systemic peripheral, and pulmonary arteries. Papaverine is a potent, specific inhibitor of PDE10A. Papaverine for treatment of erectile dysfunction (ED) is excluded from coverage.

Sarcosine, also known as N-methylglycine, is a metabolite of glycine. It shares properties with both glycine and D-serine, though its effects are weaker. Sarcosine supplementation can be used to alleviate symptoms of depression and schizophrenia, or improve cognition. It is absorbed more reliably by the body than D-serine, which can also treat similar conditions. Sarcosine is being investigated for its connection to prostate cancer. It may be a biomarker for prostate cancer, which means that if sarcosine levels in the blood are higher than normal, it could be an indicator of prostate cancer. This doesn’t mean that sarcosine itself causes cancer. More research is needed to confirm this relationship. Sarcosine’s main mechanism involves inhibiting a transporter, called GlyT1, which takes up glycine and D-serine into cells. This increases the levels of glycine and D-serine in the body and increases their effects. Sarcosine, a glycine transporter type 1 inhibitor and an N-methyl-D-aspartate (NMDA) receptor co-agonist at the glycine binding site, potentiates NMDA receptor function. Sarcosine is an inhibitory glycine receptor agonist.
