Conditions:
S-Adenosylmethionine (often referred to as SAMe) is a methyl donor and a cofactor for enzyme-catalyzed methylations, including catechol O-methyltransferase (COMT) and DNA methyltransferases (DNMT). Although present in all cells, it is concentrated in liver where 85% of all methylation reactions occur. SAM is anti-apoptotic in normal hepatocytes and normal colon epithelial cells but pro-apoptotic in liver human hepatocellular carcinoma (HCC), HepG2 cells and colon cancer cells. Because of structural instability, stable salt forms of SAM are required for its use as an oral drug. The commonly used salts: tosylate, butanedisulfonate, disulfate tosylate, disulfate ditosylate, and disulfate monotosylate. SAMe has been marketed in some European countries since the mid-1980s for the treatment of depression and for other medical conditions such as osteoarthritis (joint disease that causes joint pain and stiffness), fibromyalgia (widespread pain and stiffness). In addition, it is used to treat liver disease and migraine headaches. However, it is not formally approved in the UK for the treatment of depression, and in the USA, it is classified only as a dietary supplement. Some research suggests that it is more effective than placebo in treating mild-to-moderate depression and is just as effective as antidepressant medications without the side effects (headaches, sleeplessness, and sexual dysfunction). In addition, antidepressants tend to take 6 to 8 weeks to begin working, while It seems to begin more quickly. Researchers are not sure how SAMe works to relieve depression. But they speculate it might increase the amount of serotonin in the brain just as some antidepressants do. Many studies have examined injectable forms of SAMe, not oral supplements.

Cilnidipine (FRC-8653) is a dihydropyridine (DHP) type of calcium channel antagonist. The L-type Ca2+ channel blockade by cilnidipine affects predominantly vascular smooth muscle, thereby producing vasodilation of peripheral resistance vessels and coronary arteries. The blockade of N-type Ca2+ channels affects predominantly peripheral nerve endings of sympathetic neurons, thereby dilating blood vessels by lowering plasma catecholamine levels. Furthermore, renoprotective and neuroprotective effects as well as cardioprotective action of cilnidipine have been demonstrated in clinical practice or animal examinations. Cilnidipine was originated by Fuji & Rebio Pharmaceutical Co., Ltd. and developed jointly with Ajinomoto for the treatment of hypertension. Cilnidipine has been launched in Japan.

Timonacic or thioproline (4-Thiazolidinecarboxylic acid) is the product of condensation between cysteine and formaldehyde. Dietary timonacic slows the aging process in mammals and prolongs their life span. It exerts antioxidant and antineoplastic actions however its mechanism of action is elusive. Timonacic (brand names Heparegen or Arbitol) is used for the treatment of liver diseases.

Flupirtine is a triaminopyridine derivative having a chemical structure - 2-amino-3-ethoxy-carbonylamino-6-4-fluoro-benzylamino-pyridine. The basic molecule used for synthesis of flupirtine was 2, 6-dichoro 3-nitropyridine. It was first synthesized in 1980s in Germany and was marketed by Degussa Pharma. Flupirtine is a centrally acting, non-opioid analgesic that is available in a number of European countries for the treatment of a variety of pain states. The therapeutic benefits seen with flupirtine relate to its unique pharmacological properties. Flupirtine displays indirect NDMA receptor antagonism via activation of potassium channels and is the first representative of a pharmacological class denoted the 'selective neuronal potassium channel openers'. The generation of the M-current is facilitated by flupirtine via the opening of neuronal Kv7 potassium channels. The opening of these channels inhibits exaggerated neuronal action potential generation and controls neuronal excitability. Neuronal hyperexcitability is a physiological component of many pain states such as chronic pain, migraine and neurogenic pain.

Levodropropizine is a non-opioid cough suppressant whose peripheral antitussive action may result from its modulation of sensory neuropeptide levels within the respiratory tract. Levodropropizine exerts its antitussive effect through an inhibitory action at the level of the airway sensory nerves and it has been shown to be able to inhibit in vitro the release of neuropeptides from C-fibers. Levodropropizine is an effective antitussive drug both in children and adults, showing statistically significant better outcomes vs. central antitussive drugs in terms of overall efficacy in reducing cough intensity, frequency and night awakenings. After oral administration, Levodropropizine is absorbed from the intestine, undergoes the first-pass metabolism and reaches peak plasma concentrations approximately 90 to 120 minutes after administration. Levocloperastine undergoes extensive biotransformation and is widely distributed throughout the body. Levocloperastine can cross the placental barrier (although to a moderate extent), but there is no evidence of accumulation, and is eliminated in the form of metabolites mainly in the faeces and to a lesser degree in the urine. The pharmacological effects of Levodropropizine were confirmed in large-scale clinical trials, non-blind or comparative. In the 10 trials reported here, oral Levodropropizine caused a rapid remission (after the first day of treatment) in cough symptoms (intensity and frequency of a daytime cough and disturbed night-time sleep) in all groups of patients. In children, the improved sleep quality resulted in a significant reduction in irritability and an overall improvement in their quality of life. Importantly, in adult patients with COPD, Levodropropizine reduced the frequency and intensity of dry unproductive cough without adversely influencing the beneficial effects of underlying treatment. In clinical trials, Levodropropizine was generally well tolerated, with mild and transient nausea the only adverse event reported. There was no evidence of central adverse events with Levodropropizine.

(S)-Lercanidipine is enantiomer of antihypertensive drugs Lercanidipine, that acts by blocking L-type calcium channels, allowing relaxation and opening of blood vessels. The dihydropyridine calcium antagonists promote systemic vasodilatation by a reversible blockade of voltage-dependent Ca2+ influx through L-type channels in the cell membrane. (S)-Lercanidipine has 100- to 200-fold greater affinity than the (R)-enantiomer for the L-type calcium channel. The pharmacokinetics of (S)- Lercanidipine has been evaluated in healthy volunteers, in elderly and non-elderly patients with hypertension, and in patients with renal or hepatic impairment. Patients from these studies were investigated after receiving a single 10 or 20 mg dose of [14C]-labeled rac-Lercanidipine as a solution. The maximum plasma concentrations of (S)-Lercanidipine were reached within 2–3 h and the area under the plasma concentration-time curves were not linearly related to the dose, indicating a saturable first-pass metabolism. The absorption of (S)-LER increases after the ingestion of a high-fat meal. Lercanidipine is highly bound to plasma protein (>98%) in humans. Its volume of distribution of 2–2.5 L/kg was determined in healthy volunteers after intravenous infusion of 2 mg. Lercanidipine is extensively metabolized by CYP 3A4 to inactive pyridine derivatives. A crossover study involving a single administration of either 10 mg of (R)- or (S)-LER or 20 mg of rac-LER as a solution demonstrated no in vivo enantiomer interconversion

BQ-123 is a selective endothelin receptor-1 antagonist; it is used as a biochemical tool in the study of endothelin receptor function. BQ-123 was suspected to contribute to the regulation of vascular tone humans. However, a study involving young normotensive subjects did not demonstrate any major role for BQ-123 regulation of vascular tone.
