FENPYROXIMATE is a pyrazole acaricide widely used in the prevention of acarids (mites) in fruit plant gardens. It is a potent inhibitor of the mitochondrial proton-translocating NADH-quinone oxidoreductase (complex I).

Ameltolide (ADD 75073, LY 201116) is a 4-aminobenzamide anticonvulsant patented by Research Corporation Technologies in the USA. Ameltolide is a sodium channel antagonist, it represents a potential therapy for the treatment of epilepsy. Ameltolide had been in phase I clinical trials by Research Corporation Technologies for the treatment of epilepsy. However, this research has been discontinued.

Ufiprazole (Omeprazole sulfide) is a metabolite of Omeprazole, which is a proton pump inhibitor. Omeprazole sulfide has been shown to be a direct-acting inhibitor of CYP2C19 in pooled human liver microsomes. Ufiprazole is also a weak BRS-3 agonist.

Benzobarbital (under the brand name Benzona), a barbiturate derivative developed in Russia that is used to treat convulsive forms of epilepsy, newborn hemolytic disease, and insomnia.

Artemisone (also known as BAY-44-9585; BAY-449585) is a 10-amino-artemisinin derivative that is markedly superior in vitro and in vivo to current artemisinins against malaria and also possesses antitumor activity. Nonetheless, its low water solubility and bioavailability has limited its clinical use, that is why was studied the encapsulated artemisone against human melanoma A-375. In addition, artemisone has the potential to be efficacious for the treatment of H. pylori infection, especially in combination with antibiotics.

Palytoxin is the most potent marine toxin known that was isolated from a zoanthid of the genus Palythoa and Cyanobacteria (Trichodesmium). Palytoxin is a potent vasoconstrictor that damages the ionic gradient of the cells, causing cell death. This toxin has a strong potential for toxicity in humans and animals that is why it causes great concern worldwide. It is crucial to remove this toxin and start an aggressive topical therapy as soon as possible.

MK-3207 represents the third CGRP receptor antagonist to display clinical efficacy in migraine trials. It is a potent CGRP receptor antagonist with IC50 and Ki of 0.12 nM and 0.022 nM, highly selective versus human AM1, AM2, CTR, and AMY3. MK-3207 had been in phase II clinical trials by Merck Sharp & Dohme for the treatment of migraine. But the company had discontinued the research due to asymptomatic liver test abnormalities in 2010.

Ampyzine is a pyrazine derivative patented by Warner-Lambert Pharmaceutical Co. as a central nervous system stimulant.

Anatibant was a selective small-molecule antagonist of the bradykinin B2 receptor that was undergoing clinical development with Xytis and Fournier for the treatment of brain injuries. Anatibant reduces brain oedema in animal TBI models. Noserious toxicity was found in Phase 1 clinical trials. Following subcutaneous administration of clinically relevant doses, there were no systemic effects but there was pain, inflammation and nodule formation at the injection site. Anatibant inhibits the binding of BK to the B2 receptor. After subcutaneous injection Anatibant is bio-available and crosses the BBB.
