Cyromazine, an insect growth regulator, affects larval and pupal cuticles in dipterans and some other insects. The mode of action of this aminotriazine is not known yet, though it has been shown not to inhibit the synthesis of chitin and cuticular proteins. Cyromazine may, however, act on some step(s) of sclerotization of the cuticle. Cyromazine is not a cholinesterase inhibitor. As an insect growth regulator, cyrozine exerts its toxic action by affecting the nervous system of the immature stages (larvae) of certain insects.

Nimetazepam (Erimin) is an intermediate-acting hypnotic drug which is a benzodiazepine derivative. It was first synthesized in 1962 in Japan.

Huperzine A is a plant alkaloid derived from Club moss plant, Huperzine serrata, which is a member or the Lycopodium species. Huperzine-A is in phase III clinical trial in the USA (Alzheimer disease) and is available as a dietary supplement. It selectively and reversibly inhibits acetylcholinesterase. Huperzine A is also a NMDA receptor antagonist, which protects the brain against glutamate induced damage, and it increases nerve growth factor levels. Huperzine A is used for Alzheimer's disease, memory and learning enhancement, and age-related memory impairment. It is also used for treating a muscle disease called myasthenia gravis, for increasing alertness and energy, and for protecting against agents that damage the nerves such as nerve gases. It can cause some side effects including nausea, diarrhea, vomiting, sweating, blurred vision, slurred speech, restlessness, loss of appetite, contraction and twitching of muscle fibers, cramping, increased saliva and urine, inability to control urination, high blood pressure, and slowed heart rate. Various medications used for glaucoma, Alzheimer's disease, and other conditions (Cholinergic drugs) interacts with Huperzine A.

Etizolam is an analogue of benzodiazepine that contains thienotriazolodiazepine group. The drug was developed and approved in Japan and now is used in Japan, Italy and India for the treatment of anxiety disorders. Etizolam exerts its action through activation of GABA A receptors, moreover, the agonistic behavior was shown on isolated neurons. There are several cases when etizolam dependence was reported. In many countries the drug is recognized as a psychoactive substance and its distribution is illegal there.

Panipenem is a parenteral carbapenem antibacterial agent with a broad spectrum of in vitro activity covering a wide range of Gram-negative and Gram-positive aerobic and anaerobic bacteria, including Streptococcus pneumoniae and species producing β-lactamases. Panipenem is coadministered with betamipron (Carbenin, Daiichi Sankyo Company) to inhibit panipenem uptake into the renal tubule and prevent nephrotoxicity. In large, randomised clinical trials, panipenem/betamipron demonstrated good clinical and bacteriological efficacy (similar to that of imipenem/cilastatin) in adults with respiratory tract or urinary tract infections.

Pheneturide ((brand names Benuride, Deturid, Pheneturid, Septotence, Trinuride), a decarboxylation product of phenobarbital, has been shown to be an effective drug against seizures, and in particular psychomotor seizures. It has being marketed in Europe, including in Poland, Spain, and the United Kingdom. Pheneturide is supplied in compressed tablets each containing 200 mg. of the drug. It can also be obtained in compound tablets (" trinuride ') each of which contain 200 mg. of pheneturide, 40 mg. of diphenylhydantoin, and 15 mg. of phenobarbitone. Animal experiments have shown that pheneturide protects against drug-induced and electrically induced convulsions.

DAU 6215 (Itasetron) is a selective 5-hydroxytryptamine3 (5-HT3) antagonist, which was developed by Boehringer Ingelheim. And was investigated for treatment the nausea and vomiting induced by chemotherapy, it was confirmed that this drug possessed antiemetic properties. Also was discovered, that chronic treatment with itasetron significantly improved retention abilities of the aged rats in this memory test. However, development of itasetron was terminated.

Fipexide (aka attentil and vigilor) is a psychoactive drug of the piperazine class which was developed in Italy in 1983. It was used in Italy and France for the treatment of senile dementia but is no longer in common use due to undesirable side effects including fever and hepatitis.
