Tubocurarine, a naturally occurring alkaloid, is used to treat smoking withdrawl syndrom. Tubocurarine, the chief alkaloid in tobacco products, binds stereo-selectively to nicotinic-cholinergic receptors at the autonomic ganglia, in the adrenal medulla, at neuromuscular junctions, and in the brain. Two types of central nervous system effects are believed to be the basis of Tubocurarine's positively reinforcing properties. A stimulating effect is exerted mainly in the cortex via the locus ceruleus and a reward effect is exerted in the limbic system. At low doses the stimulant effects predominate while at high doses the reward effects predominate. Intermittent intravenous administration of Tubocurarine activates neurohormonal pathways, releasing acetylcholine, norepinephrine, dopamine, serotonin, vasopressin, beta-endorphin, growth hormone, and ACTH. Tubocurarine competes with acetylcholine for post-synaptic nicotinic NM receptors and blocks them.

Salicylamide is a non-prescription drug with analgesic and antipyretic properties (NSAID). It is used in combination with aspirin and caffeine in the over-the-counter pain remedies (such as EXAPRIN). Salicylamide can produce sedation and sleep in humans and animals. Has been used as model drug in pharmacokinetic and metabolic studies as a dophamine 2 receptor ligand. Salicylamide is a white or light pink crystals or powder. Organic compound it is a carboxamide derivative of salicylic acid.

Sulfapyridine is a competitive inhibitor of the bacterial enzyme dihydropteroate synthetase. It was used to treat of infections in humans in particular, dermatitis herpetiformis (Duhring's disease), a skin problem, but that usage was discontinued by manufacturer. It is also known, that sulfapyridine is one of the two primary metabolite of the anti-inflammatory drug salicylazosulfapyridine.

Quinacrine was initially developed as an anti-malarial drug marketed under the name Atabrine. Also it was approved for the teratment of ascites, however it was wothdrawn for both indication in 1995 and 2003, respectively. The drug is also used for the treatment of giardiasis, lupus, rheumatoid arthritis, refractory pulmonary effusion and pneumothorax, induce female sterilization etc. Proposed mechanisms of action include DNA intercalation interference with RNA transcription and translation, inhibition of succinate oxidation interference with electron transport, inhibition of cholinesterase, and inhibitor of phospholipase.

Adiphenine is a ternary amino ligand. It is used as a local anesthetic that reduces the frequency of acetylcholine-induced single-channel currents. It was originally introduced as a spasmolytic agent. Adiphenine reduced the muscle tone of the gastrointestinal tract, bile duct and gallbladder, bronchi, bladder. It affects the tone of the muscles of the eye, causing the pupil dilated (mydriasis), increased intraocular pressure, and paralysis of accommodation. Influences on the cardiovascular system, causing tachycardia and improving AV-conduction. Adiphenine side effects are: nausea, vomiting, heartburn, dizziness, headache. Adiphenine has not been widely used clinically.
