Antrafenine (SL 73033 or 2-[4-[3-(trifluoromethyl)phenyl]-1-piperazinyl]ethyl 2-[[7-(trifluoromethyl)-4-quinolinyl]amino]benzoate) showed marked analgesic activity, long duration of action, and excellent tolerance in pharmacological and toxicological studies. Antrafenine exerts anti-inflammatory effects. It has been studied in the treatment of osteoarthritis.

Broperamole has been studied as an anti-inflammatory agent.

Aminoacridine derivative that is a potent intercalating antineoplastic agent. It is effective in the treatment of acute leukemias and malignant lymphomas, but has poor activity in the treatment of solid tumors. It is frequently used in combination with other antineoplastic agents in chemotherapy protocols. It produces consistent but acceptable myelosuppression and cardiotoxic effects. Although its mechanism of action is incompletely defined, amsacrine inhibits DNA synthesis by binding to and intercalating with DNA. Amsacrine also inhibits topoisomerase II activity and may exert an effect on cell membranes. This agent also possesses immunosuppressive and antiviral properties. While amsacrine is not cell cycle phase-specific, cytotoxicity is maximal during the G2 and S phases.

AMFLUTIZOLE is a xanthine oxidase inhibitor used for the treatment of gout.

Nilvadipine (NIVADIL®) is a L-type calcium channel blocker for treatment of hypertension. It inhibits the influx of extracellular calcium through myocardial and vascular membrane pores by physically plugging the channel. The decrease in intracellular calcium inhibits the contractile processes of smooth muscle cells, causing dilation of the coronary and systemic arteries, increased oxygen delivery to the myocardial tissue, decreased total peripheral resistance, decreased systemic blood pressure, and decreased afterload.

Tolciclate [O-(1,2,3,4-tetrahydro-1,4-methanonaphthalen-6-yl)-m,N-dimethylthiocarbanilate] is an antimycotic agent with specific activity on dermatophytes. In vitro it is as active as tolnaftate, but shows greater liposolubility, which might be important for in vivo activity. When applied topically for 10 days to guinea pigs infected acutely with Trichophyton mentagrophytes (synonymous with T. asteroides), it is about three times more active than tolnaftate. Inhibition by tolciclate of sterol synthesis through blocking the step of squalene epoxidation in a fungal sterol biosynthetic pathway may be primarily involved in the antifungal action of the drug.

Propamidine, an aromatic diamidine compound, is widely used as an antimicrobial agent. Propamidine isethionate, the salt of propamidine with isethionic acid, is used in the treatment of Acanthamoeba infection. Diseases caused by Acanthamoeba include keratitis and granulomatous amoebic encephalitis.

Fenthion (trade names include Baytex™, Baycid™, and Tiguvon™, used on livestock) was first registered domestically in 1965 by the Mobay Corp., a U.S. subsidiary of Bayer AG of West Germany. Fenthion is a contact and stomach insecticide used against many sucking, biting pests, especially fruit flies, stem borers, mosquitoes, and Eurygaster cereal bugs. In mosquitoes, it is toxic to both the adult and immature forms (larvae). Once used extensively in the U.S. for controlling intestinal worms, fenthion no longer has FDA approval due to an excess number of poisoning deaths. Like most other organophosphates, its mode of action is via cholinesterase inhibition. It was used mostly for the control of grubs and lice in beef and nonlactating cattle.

Amylmetacresol (AMC) is an antiseptic used to treat infections of the mouth and throat. It is used as an active pharmaceutical ingredient in Strepsils, Gorpils and Lorsept throat lozenges. It was shown that the presence of amylmetacresol, dichloro-benzylalcohol and lidocaine block of inward sodium current.

Suramin is an antiprotozoal and anthelmintic compound. It is indicated for the treatment of African trypanosomiasis (African sleeping sickness; trypanosome fever) and Onchocerciasis (river blindness). Additionally, suramin exhibits antineoplastic action. It was discovered that suramin produced dramatic, but transient, improvement of core symptoms of autism spectrum disorder.
