Sodium dehydrocholate is a hydrocholeretic and is used to study biliary excretion.

Gentian violet ((GV) hexamethyl pararosaniline, also known as crystal violet, methyl violet) is a triphenylmethane dye with anti-bacterial, anti-fungal, anti-helminithic, anti-trypanosomal, anti-angiogenic and anti-tumor properties. GV has a lengthy history and has been used successfully as monotherapy and an adjunct to treatment in a variety of diseases. Gentian violet interacts with negatively charged components of bacterial cells including the lipopolysaccharide (on the cell wall), the peptidoglycan and DNA. A similar cell penetration and DNA binding process is thought to take place for fungal cells as well. Because Gentian violet is a mutagen and mitotic poison, cell growth is consequently inhibited. A photodynamic action of gentian violet, apparently mediated by a free-radical mechanism, has recently been described in bacteria and in the protozoan T. cruzi. Evidence also suggests that gentian violet dissipates the bacterial (and mitochondrial) membrane potential by inducing permeability. This is followed by respiratory inhibition. This anti-mitochondrial activity might explain gentian violet's efficacy towards both bacteria and yeast with relatively mild effects on mammalian cells.

Gallic acid is a polyphenol found in a variety of foods and herbs. Several studies have shown thta gallic acid has neuroprotective and anti-oxidant properties and can be a promising candidate for the treatment of cancer, cardiovascular diseases, neurodegenerative disorders, fatty liver disease and many others. Gallic acid acts by protecting cells against oxidative damage caused by reactive species often encountered in biological systems including, hydroxyl, superoxide and peroxyl and the non-radicals, hydrogen peroxide and hypochlorous acid. However, its ability to induce apoptosis, is mainly associated with its prooxidant, rather than antioxidant behavior.

Aconitine is an alkaloid found in the Aconitum species. Aconitine is a highly toxic cardiotoxin and neurotoxin. In China and other countries, the herbal extract containing aconitine was used for the treatment of pain in musculoskeletal disorders, however the safety margin between therapeutic analgesic effect of aconitine and its known cardiotoxic effect is so narrow that the treatment may cause poisoning and death. The mechanism of aconitine action is explained by its ability to activate voltage-dependent sodium-ion channels.

Strychnine is an indole alkaloid obtained from the seeds of the Indian tree Strychnos nux-vomica. It gets its scientific name “strychnos” from Carl Linnaeus, who classified it back in 1753, but it was known to the population of India way before then. Nux vomica originates in India. Strychnine-containing baits are currently labelled for below-ground use and are intended for the control of pocket gophers. Their use as indoor pesticides has been eliminated since 1989. In the past, strychnine has been used as a pesticide to control rats, moles, gophers, and coyotes. Strychnine is highly toxic to most domestic animals. Strychnine is a competitive antagonist at glycine receptors and thus a convulsant. It has been used as an analeptic, in the treatment of nonketotic hyperglycinemia and sleep apnea.

Saccharin is the most established of the artificial sweeteners on the market, this mixture of dextrose and saccharin has been in use for over a century and is found in diet versions of soft drinks. It is 300-500 times sweeter than sugar and contains zero calories. In 1977, the FDA tried to ban its use after evidence showed it caused cancer in rats. Extensive lobbying by the diet food industry allowed products to stay on the shelves as long as they carried warnings about the cancer risks in animals. This warning was removed in 2001 when the Calorie Control Council insisted the link between animal and human cancers could not automatically be made. Consumption of saccharin-sweetened products can benefit diabetics as the substance goes directly through the human digestive system without being digested. While saccharin has no food energy, it can trigger the release of insulin in humans due to its sweet taste. The T1R2/R3 sweet taste receptor exist on the surface of pancreatic beta cells. Saccharin is a unique in that it inhibits glucose-stimulated insulin secretion (GSIS) at submaximal and maximal glucose concentrations, with the other sweeteners having no effect. Investigation of saccharin’s dose-response characteristics showed that concentrations of 0.1 and 0.5 mM stimulated insulin secretion, while concentrations of 1 and 2.5 mM inhibited insulin secretion. Saccharin’s effect on insulin secretion was shown to be reversible in INS-1 832/13 clonal pancreatic beta cells after chronic exposure to 1 mM saccharin. Artificial sweeteners may affect insulin secretion via interaction with the sweet taste receptor, also saccharin may affect other cellular processes linked to insulin secretion, and that these effects are both time- and concentration-dependent
