Trospectomycin is an aminocyclitol antibiotic similar in structure to spectinomycin. The drug was originally developed by Pharmacia & Upjohn. It is a 6'-propyl analogue of spectinomycin, and lacks the aminosugars in glycosidic linkage which are thought to be responsible for the ototoxicity and nephrotoxicity associated with the aminoglycosides. The mechanism of action of trospectomycin is similar to that of its parent compound, spectinomycin: it binds to the bacterial 30S ribosome and inhibits protein synthesis. The transport mechanism for its delivery to its target site does not appear to be oxygen dependent, and this explains the in-vitro activity of trospectomycin against anaerobic organisms. Trospectomycin has activity against a broad spectrum of pathogenic organisms including Streptococcus, Haemophilus, Gardnerella, Neisseria, Peptococcus, Peptostreptococcus, Bacteroides, Mobiluncus, Chlamydia, Mycoplasma and Ureaplasma spp. Results of in-vivo testing suggest potential utility in a variety of clinical conditions including non-gonococcal urethritis, chlamydial cervicitis, gonorrhoea, pelvic inflammatory disease, pneumonia, anaerobic infections and meningitis. Trospectomycin progressed to late stage clinical trials for treatment of pelvic inflammatory disease (chlamydia) before being abandoned for commercial reasons as the third generation cephalosporins and second generation macrolides in development and use were judged superior at the time.

Cinoxolone is a derivative of glycyrrhetinic acid. Is is claimed to possess antiulcer properties.

AST-1306, also known as Allitinib, is an orally active potent, selective, irreversible inhibitor of the HER family of receptor tyrosine kinases. AST-1306 inhibits the enzymatic activities of wild-type epidermal growth factor receptor (EGFR) and ErbB2 as well as EGFR resistant mutant in both cell-free and cell-based systems. AST1306 potently suppressed tumor growth in ErbB2-overexpressing adenocarcinoma xenograft and FVB-2/N(neu) transgenic breast cancer mouse models. Allitinib is in Phase I clinical trial for the treatment of advanced solid tumors. Serious adverse effects detected were: diarrhea, dehydration and hyperbilirubinemia.

Tinazoline is an imidazole derivative patented by Ciba-Geigy A.-G. as vasoconstrictors, particularly as nasal decongestants in the treatment of common cold. Tinazoline showing potent and long-acting vasoconstrictor activity on several vascular beds in dogs, guinea-pigs, cats, and rabbits. The vasoconstrictor effect has been shown in animals to be due to a stimulation of the 1-adrenoceptors and the compound does not exhibit any B-adrenoceptor agonist activity.

Nonaperone, a butyrophenone, is a neuroleptic agent. It is antipsychotic in schizophrenics at doses which do not elicit extrapyridal side effects.

Alazanine triclofenate is a mixture of one molecule of 3-ethyl-2-(3-(3-ethyl-2-benzothiazolinylidene)propenyl)benzothiazolium 2,4,5-trichlorophenate and two molecules of 2,4,5-trichlorophenol. It is an antiparasitic agent. It is antimalarial drug, highly active against multiple Plasmodium falciparum isolates with IC50 value of 2.36E-07 M.
