Aspartame (l-aspartyl-l-phenylalanine methyl ester) known to the public as NutraSweet has been the subject of controversy since it first became an ingredient in food products. The perceived sweetness of aspartame in humans is due to its binding of the heterodimer G-protein coupled receptor formed by the proteins TAS1R2 and TAS1R3. Aspartame was used in experiments on animals to study its role in delays of osteoarthritis. It was shown, that aspartame improved bone cortical density and muscle mass, and might contribute to a better quality of life for these diseased animals. In addition, was investigated the effect in patients with sickle cell anemia. It was revealed, that oral administration of aspartame lead inhibition of sickle cells. That effect was explained by binding aspartame with two human Bence Jones proteins: Mcg and Sea. Thus was suggested, that aspartame could interfere with sickle hemoglobin fibril formation. Then several studies showed that aspartame had no effect on the polymerization of sickle hemoglobin.

Ceftiofur is an antibiotic of the cephalosporin type (third generation), licensed for use in veterinary medicine only. It was first described in 1987. It is marketed by pharmaceutical company Zoetis as Excenel, Naxcel, and Excede and is also the active ingredient in that company's Spectramast LC (lactating cow formulation) and Spectramast DC (dry cow formulation) product. Ceftiofur has worldwide approvals for respiratory disease in swine, ruminants (cattle, sheep and goats) and horses and has also been approved for foot rot and metritis infections in cattle. Ceftiofur has also been approved in various countries for early mortality infections in day-old chicks and turkey poults. Ceftiofur (NAXCEL) is indicated for treatment of bovine respiratory disease (shipping fever, pneumonia) associated with Mannheimia haemolytica, Pasteurella multocida, and Histophilus somni. NAXCEL is also indicated for treatment of acute bovine interdigital necrobacillosis (foot rot, pododermatitis) associated with Fusobacterium necrophorum and Bacteroides melaninogenicus.

Cloprostenol is a synthetic prostaglandin analogue structurally related to Prostaglandin F2α (PGF2α), for use in cattle and horses. As a potent luteolytic agent it causes functional and morphological regression of the corpus luteum (luteolysis) in cattle and horses followed by return to oestrus and normal ovulation.

Sodium Lauryl Sulfate (SLS) is an anionic surfactant naturally derived from coconut and/or palm kernel oil. It usually consists of a mixture of sodium alkyl sulfates, mainly the lauryl. It is a widely used and inexpensive chemical found in many mainstream personal hygiene products such as shampoos, toothpastes, soaps, detergents and body wash. SLS is a detergent and surfactant, which essentially means that it breaks surface tension and separates molecules in order to allow better interaction between the product and your hair. It is also widely used as a skin irritant when testing products used to heal skin conditions. It was found that SLS represented a potential candidate for the use as a topical microbicide to prevent the sexual transmission of HIV-1, herpes, human papillomavirus and possibly other sexually transmitted pathogens. The mechanism of action of SLS involves the solubilization of the viral envelope and/or the denaturation of envelope and/or capsid proteins.

Mizolastine (Mizollen) is a long-acting H1 -antihistamine indicated for the symptomatic relief of seasonal allergic rhinoconjunctivitis (hay fever), perennial allergic rhinoconjunctivitis and urticaria. It blocks H1 receptors and is commonly fast-acting. It does not prevent the actual release of histamine from mast cells, just prevents it binding to receptors. Side effects can include dry mouth and throat

Bemesetron, also known as MDL 72222, is a potent and highly selective antagonist of neuronal 5-hydroxytryptamine receptors, 5HT3. Bemesetron possesses antiemetic efficacy in comparison with a high-dose metoclopramide regimen (HDM) for chemotherapy-induced nausea and vomiting. But this application is not clinically used. Drug is used as scientific tool for the study 5HT3 receptor properties in the actions of drugs of abuse.

Ramatroban is a dual antagonist of thromboxane A2 receptor and PGD2 receptor. The drug was developed by Bayer and tested for the treatment of asthma and allergic rhinitis. In Japan ramatroban reached final approval and is being marketed under the name Baynas. In vitro studies have shown that the drug effectively inhibits smooth muscle cells contraction.

Benserazide is a peripherally-acting aromatic L-amino acid decarboxylase (AADC) or DOPA decarboxylase inhibitor. Benserazide is only used in conjunction with L-dopa for the treatment of Parkinson's disease under the brand name Madopar in the UK. Madopar HBS (125 mg) is a controlled-release dosage form with 100 mg L-dopa and 25 mg benserazide.

Fenclozic acid emerged in the late 1960s as a promising carboxylic acid non-steroidal anti-inflammatory drug candidate that demonstrated potent anti-inflammatory, anti-pyretic and analgesic properties. Whole body autoradiography showed fenclozic acid distribution into all tissues except the brain, with radioactivity still detectable in blood, kidney and liver at 72 h post-dose. Fenclozic acid was compared with aspirin in a double-blind, crossover trial in patients with rheumatoid arthritis. It was concluded that fenclozic acid afforded symptomatic relief and was comparable to aspirin. Unfortunately, hepatotoxicity was observed in subsequent trials and the drug was withdrawn from the clinic.

Dosmalfate (diosmin heptakis) is a cytoprotective agent of flavonoid nature. It acts as a non-systemic antiulcer agent lacking antisecretory activity, capable of constituting a complex with the pepsin protein substrate or with pepsin itself. The drug was marketed in Spain under the name Diotulfase (among the others) for the treatment of NSIAD-induced ulcer, however, it is no longer available.
