CHEMICAL (ACHIRAL)
Conditions:
Guanidine is a small basic compound. Guanidine stimulates the neuromuscular junction presynaptically by inhibiting voltage-gated potassium (Kv) channels, leading to the enhanced release of acetylcholine in the synaptic cleft. This stimulatory effect of guanidine underlies its use in the therapy for the neuromuscular diseases. The hydrochloride salt of guanidine was approved by FDA for the reduction of the symptoms of muscle weakness and easy fatigability associated with the myasthenic syndrome of Eaton-Lambert.

IOBENGUANE I-123 (AdreView®) is a radiopharmaceutical agent for gamma-scintigraphy. It is similar in structure to the antihypertensive drug guanethidine and to the neurotransmitter norepinephrine (NE). IOBENGUANE is, therefore, largely subject to the same uptake and accumulation pathways as NE. It is taken up by the NE transporter in adrenergic nerve terminals and stored in the presynaptic storage vesicles. IOBENGUANE accumulates in adrenergically innervated tissues such as the adrenal medulla, salivary glands, heart, liver, spleen, and lungs as well as tumors derived from the neural crest. By labeling IOBENGUANE with the isotope iodine 123 (I-123), it is possible to obtain scintigraphic images of the organs and tissues in which the radiopharmaceutical accumulates. IOBENGUANE I-123 (AdreView®) is indicated for use in the detection of primary or metastatic pheochromocytoma or neuroblastoma. It is also used for scintigraphic assessment of sympathetic innervation of the myocardium by measurement of the heart to mediastinum (H/M) ratio of radioactivity uptake in patients with New York Heart Association (NYHA) class II or class III heart failure and left ventricular ejection fraction (LVEF) ≤ 35%. Among these patients, IOBENGUANE I-123 (AdreView®) may be used to help identify patients with lower one and two-year mortality risks, as indicated by an H/M ratio ≥ 1.6.

Tizanidine is a short-acting drug for the management of spasticity. Tizanidine is an agonist at a2-adrenergic receptor sites and presumably reduces spasticity by increasing presynaptic inhibition of motor neurons. In animal models, tizanidine has no direct effect on skeletal muscle fibers or the neuromuscular junction, and no major effect on monosynaptic spinal reflexes. The effects of tizanidine are greatest on polysynaptic pathways. The overall effect of these actions is thought to reduce facilitation of spinal motor neurons. Side effects include dizziness, drowsiness, weakness, nervousness, hallucinations, depression, vomiting, dry mouth, constipation, diarrhea, stomach pain, heartburn, increased muscle spasms, back pain, rash, sweating, and a tingling sensation in the arms, legs, hands, and feet.

Conditions:
Iobenguane I-131 is a radioactive therapeutic agent. The drug contains radioactive isotope I-131, which decays by electron emission with a half-life of about 8 days. By the chemical structure, iobenguane is similar to the neurotransmitter norepinephrine and is subject to the same uptake and regulation pathways. After intravenous administration, iobenguane I-131 accumulates within pheochromocytoma and paraganglioma cells, and radiation from the radioactive decay causes cell death and tumor necrosis. Iobenguane I-131 was approved by the FDA for the treatment of adult and pediatric patients with iobenguane scan positive, unresectable, locally advanced or metastatic pheochromocytoma or paraganglioma who require systemic anticancer therapy. Iobenguane I-131 is investigated in clinical trials as a treatment of neuroblastoma, ganglioneuroblastoma and other tumors of neuroendocrinal origin.

Cimetidine is a histamine H2-receptor antagonist. It reduces basal and nocturnal gastric acid secretion and a reduction in gastric volume, acidity, and amount of gastric acid released in response to stimuli including food, caffeine, insulin, betazole, or pentagastrin. It is used to treat gastrointestinal disorders such as gastric or duodenal ulcer, gastroesophageal reflux disease, and pathological hypersecretory conditions. Cimetidine inhibits many of the isoenzymes of the hepatic CYP450 enzyme system. Other actions of Cimetidine include an increase in gastric bacterial flora such as nitrate-reducing organisms. Cimetidine binds to an H2-receptor located on the basolateral membrane of the gastric parietal cell, blocking histamine effects. This competitive inhibition results in reduced gastric acid secretion and a reduction in gastric volume and acidity.

Meobentine is an antiarrhythmic agent. Meobentine significantly increases the electrical ventricular fibrillation threshold in animal models. Meobentine may prevent induction of ventricular tachycardia or fibrillation, or reduce frequency of complex ventricular ectopy in selected patients refractory to other antiarrhythmic agents, but the response rate is relatively low.

Guanoxyfen sulfate is an antidepressant, antihypertensive. Guanoxyfen sulfate is an inhibitor of vasoconstrictor responses to sympathetic nerve stimulation. It could potentiate the actions of adrenaline and noradrenaline. It also could increase the blood glucose concentration and decrease the appetite.

Impromidine is a highly potent and specific histamine H2 receptor agonist used diagnostically as a gastric secretion indicator. The value of impromidine as an effective acid-secretory stimulant is limited by its tendency to cause cardiovascular side-effects, that mediated by H2-receptors in the cardiovascular system.
