Quinethazone
Quinethazone is only found in individuals that have used or taken this drug. It is a thiazide diuretic used to treat hypertension. Common side effects include dizziness, dry mouth, nausea, and low potassium levels.As a diuretic, quinethazone inhibits active chloride reabsorption at the early distal tubule via the Na-Cl cotransporter, resulting in an increase in the excretion of sodium, chloride, and water. Thiazides like quinethazone also inhibit sodium ion transport across the renal tubular epithelium through binding to the thiazide sensitive sodium-chloride transporter. This results in an increase in potassium excretion via the sodium-potassium exchange mechanism. The antihypertensive mechanism of quinethazone is less well understood although it may be mediated through its action on carbonic anhydrases in the smooth muscle or through its action on the large-conductance calcium-activated potassium (KCa) channel, also found in the smooth muscle.

Methaqualone
Methaqualone, also known as optimil or ortonal, belongs to the class of organic compounds known as quinazolines. Quinazolines are compounds containing a quinazoline moiety, which is made up of two fused six-member aromatic rings, a benzene ring and a pyrimidine ring. Methaqualone is a drug which is used for the treatment of insomnia, and as a sedative and muscle relaxant. Methaqualone exists as a solid and is considered to be practically insoluble (in water) and relatively neutral.

Metolazone
Metolazone is only found in individuals that have used or taken this drug. It is a quinazoline-sulfonamide that is considered a thiazide-like diuretic which is long-acting so useful in chronic renal failure. It also tends to lower blood pressure and increase potassium loss. [PubChem]The actions of metolazone result from interference with the renal tubular mechanism of electrolyte reabsorption. Metolazone acts primarily to inhibit sodium reabsorption at the cortical diluting site and to a lesser extent in the proximal convoluted tubule. Sodium and chloride ions are excreted in approximately equivalent amounts. The increased delivery of sodium to the distal tubular exchange site results in increased potassium excretion. Metolazone does not inhibit carbonic anhydrase. The antihypertensive mechanism of action of metolazone is not fully understood but is presumed to be related to its saluretic and diuretic properties.

Halofuginone
Veterinary antiprotozoal agent. Poultry feed additive for prevention of coccidiosis. Halofuginone is a coccidiostat used in veterinary medicine. It is derived from dichrorine, a kind of alkaloids which can be found in the Chinese herb Chang Shan (Dichroa febrifuga). Halofuginone, a fully synthetic small molecule, is a potent and selective regulator of stromal cell activation, cell migration and Collagen type I synthesis, a process that has been identified as a master switch in the bodys tissue repair process D000890 - Anti-Infective Agents > D000977 - Antiparasitic Agents > D000981 - Antiprotozoal Agents D006133 - Growth Substances > D043924 - Angiogenesis Modulating Agents D004791 - Enzyme Inhibitors > D011500 - Protein Synthesis Inhibitors D000970 - Antineoplastic Agents > D020533 - Angiogenesis Inhibitors D006133 - Growth Substances > D006131 - Growth Inhibitors Halofuginone (RU-19110), a Febrifugine derivative, is a competitive prolyl-tRNA synthetase inhibitor with a Ki of 18.3 nM[1][2]. Halofuginone is a specific inhibitor of type-I collagen synthesis and attenuates osteoarthritis (OA) by inhibition of TGF-β activity[3][4]. Halofuginone is also a potent pulmonary vasodilator by activating Kv channels and blocking voltage-gated, receptor-operated and store-operated Ca2+ channels. Halofuginone has anti-malaria, anti-inflammatory, anti-cancer, anti-fibrosis effects[5].
Lercanidipine
Lercanidipine is only found in individuals that have used or taken this drug. It is a calcium channel blocker of the dihydropyridine class. It is sold under various commercial names including Zanidip.By deforming the channel, inhibiting ion-control gating mechanisms, and/or interfering with the release of calcium from the sarcoplasmic reticulum, Lercanidipine inhibits the influx of extracellular calcium across the myocardial and vascular smooth muscle cell membranes The decrease in intracellular calcium inhibits the contractile processes of the myocardial smooth muscle cells, causing dilation of the coronary and systemic arteries, increased oxygen delivery to the myocardial tissue, decreased total peripheral resistance, decreased systemic blood pressure, and decreased afterload.

Anagrelide
Anagrelide is only found in individuals that have used or taken this drug. It is a drug used for the treatment of essential thrombocytosis (ET; essential thrombocythemia). It also has been used in the treatment of chronic myeloid leukemia. [Wikipedia]The mechanism by which anagrelide reduces blood platelet count is still under investigation. Studies in patients support a hypothesis of dose-related reduction in platelet production resulting from a decrease in megakaryocyte hypermaturation. In blood withdrawn from normal volunteers treated with anagrelide, a disruption was found in the postmitotic phase of megakaryocyte development and a reduction in megakaryocyte size and ploidy. At therapeutic doses, anagrelide does not produce significant changes in white cell counts or coagulation parameters, and may have a small, but clinically insignificant effect on red cell parameters. Anagrelide inhibits cyclic AMP phosphodiesterase III (PDEIII). PDEIII inhibitors can also inhibit platelet aggregation. However, significant inhibition of platelet aggregation is observed only at doses of anagrelide higher than those required to reduce platelet count.
