Alfurolol is a beta-adrenergic blocker. It is non-selective blocking drug with both intrinsic sympathomimetic activity and weak membrane stabilizing activity. There is also evidence that, unlike other beta-blocking drugs, only extremely small amounts of alfurolol cross the blood-brain barrier: because of this property, it has very little effect on the CNS. Alfurolol consistently produced a reduction in exercise heart rate at all times during the seven-hour period of observation, and the reductions were significantly different from the corresponding values after placebo treatment. Alfurolol is active both on heart rate and systolic pressure.

Levormeloxifene (INN) is an experimental selective estrogen receptor modulator (SERM) that was being developed as an alternative to estrogen replacement therapy for the treatment and prevention of postmenopausal bone loss. Levormeloxifene is the levorotatory enantiomer of non-hormonal, non-steroidal oral contraceptive -- ormeloxifene (trade names Novex-DS, Centron, and Sevista). The development of Levormeloxifene was stopped because of a high incidence of gynecologic adverse events during clinical trials.

METHYLMETHIONINE (S-Methionine methyl sulfonium, SMMS) chloride is a derivative of methionine metabolism in some plants. Methylmethionine has therapeutic effects on gastrointestinal ulceration potentially via its ability to promote dermal fibroblast migration and growth. The natural derivative Methylmethionine is biosynthesized from L-methionine which is first converted to S-adenosylmethionine. The subsequent conversion, involving replacement of the adenosyl group by a methyl group is catalyzed by the enzyme methionine S-methyltransferase. Methylmethionine is particularly abundant in plants, being more abundant than methionine. S-Methylmethionine is sometimes referred to as vitamin U, but it is not considered a true vitamin. The term was coined in 1950 by Garnett Cheney for uncharacterized anti-ulcerogenic factors in raw cabbage juice that may help speed healing of peptic ulcers.

Cetiedil is effective potassium channel blocker used as a peripheral vasodilator to treat patients with painful crises in sickle cell anemia and pain in the extremities caused by an arterial disease. Known pharmacological properties of the drug include vascular smooth muscle relaxation, inhibition of phosphodiesterase with the consequent increase in circulating cyclic AMP concentration, blockade of the effect of bradykinin and serotonin, analgesia, inhibition of platelet aggregation and the decrease of plasma and blood viscosity and plasma fibrinogen level. The antisickling effect of cetiedil is explained mainly in the light of the changes it induces in the activities of membrane-bound ATPases and the permeability properties of the erythrocyte membrane to cations and anions.

Vincamine is the major alkaloid of Vinca minor. Although vincamine has been used therapeutically for almost three decades, the exact mechanisms of action and its effects are still unknown. Vincamine is a peripheral vasodilator that increases blood flow to the brain. Vincamine is beneficial to the nervous system's cells feeding and protecting processes and is utilized as an adjuvant in case of cerebrovascular insufficiency, age-related psycho-behavioral disorders, post concussion syndrome in head trauma, in case of post-stroke sequels. Vincamine may be used as a dietary nootropic supplement.

Mosapramine (Cremin) is used to treat chronic schizophrenia in Japan. It is a potent dopamine antagonist with high affinity to the dopamine receptor subtypes 2, 3 and 4, and with moderate affinity for the 5-HT2 receptors

Dimethylbenzylamine is used as a catalyst for soft polyester-based polyurethane systems, semisolid foams, pre-polymerisation agents, to improve the effect of impregnation agents on cellulose fibres. Contact with skin causes burns

Vetrabutine is a spasmolytic agent. As a musculotropic spasmolytic agent vatrabutine was reported to act directly on the smooth muscle fibers and to have no neurotropic activity. In pigs, its activity was specific to the uterine body and cervical musculature where it acted on the myometrial cells, sealing off the membrane against the passage of potassium ions, thereby increasing membrane potential and lowering tonus. Vetrabutine was of moderate acute oral toxicity. Vetributine hydrochloride has been used in human medicine as a spasmolytic agent in obstetrics.

Tetradonium is a cationic germicidal detergent, often used in disinfectant and deodorant compositions.

Amixetrine is a drug that was formerly marketed in France but is now no longer sold. Amixetrine therapeutic functions are: aniinflammatory, anticholinergic, antidepressant, antispasmodic. The urinary metabolites of N-(2-phenyl-2-isoamyloxy) ethyl-pyrrolidine-hydrochloride (amixetrine) studied in man and in the dog demonstrated a comparable mode of transformation of the drugs for both species. In man, as in the dog, the principal metabolite coming from an omega-1-oxidation of the isoamyl chain corresponded to 2-phenyl-2-butoxy-(3-methyl-3-ol)ethyl-pyrrolidine.
