Tilarginine is L-N-monomethyl arginine (L -NMMA), a non-selective inhibitor of nitric oxide synthase (NOS), which has been studied in the treatment of septic shock and cardiogenic shock complicating myocardial infarction. Despite strong evidence that excessive nitric oxide (NO) production plays a pivotal role in the pathogenesis of septic shock and may contribute to the pathogenesis of cardiogenic shock complicating myocardial infarction, outcome studies in these two disorders have proved disappointing. Tilarginine therapy was associated with an excess mortality, particularly at doses > 5 mg/(kg h), in septic shock, whereas the effects of a lower dose (1 mg/(kg h)) in cardiogenic shock complicating myocardial infarction were neutral. The excess mortality in patients with septic shock was almost certainly the result of unfavorable hemodynamic changes induced by Tilarginine (decreased cardiac output, increased pulmonary vascular resistance and reduced tissue oxygen delivery) whereas the lack of benefit in patients with cardiogenic shock complicating myocardial infarction may have been because the dose of Tilarginine was too low.

Higenamine HCl (norcoclaurine) is a plant-based alkaloid widely used as nutritional supplement in food and beverage industries. It exists in variety of plants including Tinospora crispa, Nandina domestica, Gnetum Parvifolium C.Y. Cheng, sarum Heterotropoides, Nelumbo nucifera. It was initially isolated from Aconitum and identified as the active cardiotonic component of this medicinal plant used as local and traditional medicines in many Asian regions for the treatment of various diseases such as collapse, syncope, painful joints, oedema, bronchial asthma etc. Various pharmacological properties and potentially multi-spectral medical applications of higenamine have been reviled in many in vitro and in vivo studies conducted in animals and humans. Pharmacological properties of higenamine include positive inotropic and chronotropic effect, activating slow channel effect, vascular and tracheal relaxation effect, anti-thrombotic, anti-apoptotic and anti-oxidative effect, anti-inflammatory and immunomodulatory effect. Studies on higenamine showed potential therapeutic effects for diseases like heart failure, disseminated intravascular coagulation (DIC), shock, arthritis, asthma, ischemia/reperfusion injuries and erectile dysfunction. Higenamine has been tested as a candidate of pharmacologic stress agent in the detection of coronary artery diseases (CADs) in human clinical studies in China. In animal models, higenamine has been demonstrated to be a β2 adrenoreceptor agonist. It partly exerts its actions by the activation of adenylate cyclase, responsible for boosting the cellular concentrations of the adrenergic second messenger, cAMP. Via a beta-adrenoceptor mechanism higenamine, induced relaxation in rat corpus cavernosum, leading to improved vasodilation and erectile function. Related to improved vasodilatory signals, higenamine has been shown to possess antiplatelet and antithrombotic activity via a cAMP-dependent pathway, suggesting it may contribute to enhanced vasodilation and arterial integrity. Anti-apoptotic and cardiac protective effects of higenamine were shown to be mediated by the β2-AR/PI3K/AKT cascade. Higenamine is marketed as a dietary supplement for weight loss and sport performance, and is added to many fat burning supplements. Along with many other β2 agonists, higenamine is prohibited by World Anti-Doping Agency for use in sports.

Betaxolol is a competitive, beta(1)-selective (cardioselective) adrenergic antagonist. Betaxolol is used to treat hypertension, arrhythmias, coronary heart disease, glaucoma, and is also used to reduce non-fatal cardiac events in patients with heart failure. (R)-Betaxolol (Dextrobetaxolol) is the R-isomer of Betaxolol (B328000), a cardioselective β1-adrenergic blocker. It is also an antihypertensive and antiglaucoma agent. Dextrobetaxolol had a much weaker affinity at both b1 and b2 receptors than levobetaxolol. Levobetaxolol (Kb=6 nM at b1 and Kb=39 nM at b2 receptors) more potently inhibited functional activities in cells expressing human recombinant b1 and b2 receptors than dextrobetaxolol (Kb=350 and 278 nM, respectively). Likewise, levobetaxolol was a more potent antagonist in isolated tissues than dextrobetaxolol. In functional assays in cultured human NPE cells levobetaxolol (Ki =16.4 nM) was a potent antagonist of isoproterenol-induced cAMP production with dextrobetaxolol (Ki =2.9 uM) being considerably weaker than the latter antagonist. In ocular hypertensive cynomolgus monkeys, levobetaxolol was more effective at reducing IOP than dextrobetaxolol. The results of the study of the pharmacokinetic behavior of the R and S enantiomers of betaxolol following iv and oral administration of the racemate to healthy male subjects failed to reveal any important difference between the pharmacokinetics of the R and S enantiomer of betaxolol. Thus, the pharmacokinetic behavior of racemic betaxolol accurately reflects the behavior of betaxolol enantiomers in this subject group.

Proroxan is a non-selective а-adrenoblocker. Proroxan was found to prevent the development of hypertensive crises and improve cerebral bioelectrical parameters in most of hypertensive patients. Proroxan has been used as an antihypertensive and in the treatment of Ménière’s disease, motion sickness, and allergic dermatitis.

Dihydromorphine is a semi-synthetic opioid derived from morphine. dihydromorphine is a moderately strong analgesic and is used clinically in the treatment of pain and is also the active metabolite of dihydrocodeine. Dihydromorphine acts as an agonist at the μ-opioid (mu), δ-opioid (delta) and κ-opioid (kappa) receptors. Dihydromorphone is approved for clinical use in the United States, Europe, and Japan; and sold under the brand name Dilaudid. Similar to morphine, and other morphine derivatives, hydromorphone has a high potential for addiction and abuse and is listed as a Schedule II drug in the United States Controlled Substances Act of 1970 (and similarly regulated in other countries).

Nabiximols (USAN, trade name Sativex) is a specific extract of Cannabis that was approved as a botanical drug in the United Kingdom in 2010 as a mouth spray to alleviate neuropathic pain, spasticity, overactive bladder, and other symptoms of multiple sclerosis. Nabiximols is an oromucosal spray of a formulated extract of the cannabis sativa plant that contains the principal cannabinoids tetrahydrocannabinol (THC) and cannabidiol (CBD) as well as specific minor cannabinoids and other non-cannabinoid components. THC is a partial agonist and can block activation by other ligands of both cannabinoid receptors (CBR). THC effects include analgesia, short-term memory loss, muscle relaxation, antiemesis, appetite stimulation, and anti-inflammatory activity. CBD acts on CBR and TRPV1, while also inhibiting reuptake and hydrolysis of anandamide N-arachidonylethanolamine (AEA). CBD effects include anticonvulsant, muscle relaxant, anxiolytic, neuroprotective, antioxidant, anti-inflammatory, immunomodulatory and anti-psychotic activity. CBD modulates some of the more undesirable psychological adverse effects of THC through both pharmacokinetic and pharmacodynamic effects. Each 100 μl spray contains: 2.7 mg of THC and 2.5 mg of CBD. Nabiximols was approved in other European countries and Canada.

Fabomotizole (also known as Afobazole) is a selective non-benzodiazepine anxiolytic which was developed in Russia and launched in 2006. The drug is used for the treatment of wide range of diseases: generalized anxious disorders, neurasthenia, adaptation disorders, sleep disorders, for alleviation of withdrawal syndrome. According to the drug label (in Russian), its action is related to the interaction with sigma-1 receptors.

Sodium 1-Naphthaleneacetate (SODIUM 1-NAPHTHALENEACETATE) is a plant growth regulator. It has being shown that root application of certain concentration of sodium naphthalene acetate (SNA) could promote the growth of tomato seedlings by increasing the tomato root activity, protective enzymes activity, Pn and regulating endogenous hormone concentration under suboptimum temperature and light condition.
