<p>4-Phenyl-1,2,3,4-tetrahydroisoquinoline HCl (4PTI) is a purgative drug that is used for the treatment of chronic kidney disease. It has been shown to have an inhibitory effect on cancer cells in culture. 4PTI prevents the uptake of glucose and fatty acids into the cell by binding to the cellular receptor for these substances. This binding inhibits cellular uptake of glucose and fatty acids by inhibiting the translocation of GLUT1 from intracellular compartments to the plasma membrane. 4PTI also blocks dopamine release from nerve terminals in rat striatum by inhibiting dopamine uptake.</p>

<p>4,6-Dihydroxybenzene-1,3-dicarbonitrile (4,6DBCN) is a glycosylase that selectively removes damaged nucleotides from the DNA backbone. 4,6DBCN has been shown to protect mammalian cells against oxidative damage by removing reactive oxygen species (ROS) and reducing the redox potential. This drug has been shown to be effective in preventing cancer and neurodegenerative diseases such as Alzheimer's disease. The effectiveness of 4,6DBCN is dose-dependent, with lower doses inducing cell recruitment and death while higher doses cause excision of damaged DNA.</p>

<p>Dimebon is a drug that binds to dopamine receptors (D2 and D3) and inhibits locomotor activity in rats. It also has been found to be effective in the treatment of cancer-induced cachexia, as well as bowel disease. Dimebon is a hydrogenated form of rac-(4aR,9bS)-2,8-dimethyl-1H,2H,3H,4H,4aH,5H,9bh-pyrido[4,3-b]indole. The drug was originally synthesized in the Soviet Union for use as an antidepressant but was never marketed because it caused severe side effects such as tardive dyskinesia. Dimebon has been shown to cause neuronal death through inhibition of the growth factor BDNF and its receptor activity. It also blocks dopamine release from nerve cells in the striatum. Dimebon is water soluble and can be taken orally or injected intravenously.</p>

<p>3-Methyl-8-hydroxyquinoline (3MQ) is a chemical compound that has been shown to be an inhibitor of the enzyme cyclen. 3MQ binds to the active site of cyclen and blocks the binding of calcium ions, preventing the formation of calcium complexes with cyclen. This inhibition leads to a decrease in cyclen activity and an increase in the synthesis of protein. 3MQ has also been shown to be potent inhibitor against chloride ion currents through voltammetry experiments. It was found that its redox potential is very low, which suggests that it can be used as a probe for electron transfer reactions in cells. The photophysical properties of 3MQ have also been studied and it was found that this molecule absorbs light at wavelengths between 400–600 nm, which may lead to its use as a photosensitizer or photoantagonist for photodynamic therapy.</p>
