Bensuldazic acid was used in veterinary as an antifungal agent.

Ecenofloxacin (CFC-222), a fluoroquinolone, is a broad-spectrum antibacterial compound acting as a ype II DNA topoisomerase inhibitor. It exerts antibacterial activities against gram-positive, gram-negative, and anaerobic organisms. Ecenofloxacin development as an antibacterial agent has been discontinued.

Kynurenic acid is a product of the normal metabolism of amino acid L-tryptophan which has been shown to have a neuroactive profile. It exhibits activity against NMDA receptors and Neuronal acetylcholine receptor subunit alpha-7. It has been investigated as a potential therapeutic compound and as a biomarker in a number of neurological disorders. Although Kenyruic acid exhibits a poor penetration of the blood-brain barrier, it remains to be of particular interest to those researching Schizophrenia.

Rolafagrel (FCE 22178) is a selective thromboxane synthase inhibitor that has been evaluated for use in the treatment of diabetic nephropathy and thrombosis. Rolafagrel inhibits platelet and glomerular thromoxane synthase in animal and human kidney disease. A phase I clinical trial did not report drug-related adverse events. No information is available on current use of rolafagrel.

Carbendazim is a broad-spectrum benzimidazole antifungal with potential antimitotic and antineoplastic activities widely used as a fungicide in agriculture and home gardening, and as an antihelminthic in veterinary medicine. As a fungicide, carbendazim used for controls Ascomycetes, Fungi Imperfecti, and Basidiomycetes on a wide variety of crops, including bananas, cereals, cotton, fruits, grapes, mushrooms, ornamentals, peanuts, sugarbeet, soybeans, tobacco, and vegetables. Carbendazim is a chemically stable and relatively persistent fungicide which only metabolizes to a limited extent in plants and in soil. The only detected metabolite is 2-aminobenzimidazole, which constitutes less than 5% of the total residues in leaves. Carbendazim may be anticipated to metabolize in the animal into hydroxylated analogues which may appear in meat and milk products. Carbendazim acts as a mitotic poison by altering tubulin binding and microtubule formation. This has been proposed as a possible mechanism of action for the developmental abnormalities seen in animal studies with high concentrations.

Prazocillin is 6-aminopenicillanic acid derivative patented by Chinoin Gyogyszer es Vegyeszeti Termekek Gyara Rt. as a bactericidal compound. The activity of Prazocillin against Staphylococcus aureus strains was the same as that of dikloxacillin, but Prazocillin was more active against Bacillus subtilis ATCC 6633. Prazocillin had a bactericidal effect on a penicillin-resistant S. aureus strain at concentrations of 1 μg/ml. Pyrazocillin inhibits bacterial penicillinase in vitro.

Iganidipin is a new dihydropiridynic derivative of calcium antagonist. It is the only currently available calcium antagonist in the form of ophthalmic solution. Its topical administration increases ipsilateral optic nerve head blood flow in rabbits and monkeys and inhibits the contraction of blood vessels induced by endothelin -1. Iganidipin is also used for treat Angina pectoris and Hypertension.

Aderbasib, also known as INCB007839, is an orally bioavailable low nanomolar hydroxamate-based inhibitor of the ADAM (A Disintegrin And Metalloprotease) family of multifunctional membrane-bound proteins with potential antineoplastic activity. Aderbasib represses the metalloproteinase "sheddase" activities of ADAM10 and ADAM17, which may result in the inhibition of tumor cell proliferation. In preclinical studies, Aderbasib with lapatinib prevented the growth of HER-2/neu–positive BT474-SC1 human breast cancer xenografts in vivo. Aderbasib was being developed by Incyte as a potential adjunctive treatment for metastatic breast cancer. Aderbasib in combination with trastuzumab increased the response rate in HER2 positive metastatic breast cancer patients with advanced disease, relative to historical controls (50% versus 15–35%). INC7839 also improved progression-free survival in a subset of the patients expressing the p95 fragment of HER2. Aderbasib development was halted in 2011 after positive findings from Phase II trials were contradicted by further research. Aderbasib is currently being tested in combination with rituximab for diffuse large B cell non-Hodgkin lymphoma.
