Conditions:

Amodiaquine is a medication used to treat malaria, including Plasmodium falciparum malaria when uncomplicated. The mechanism of plasmodicidal action of amodiaquine is not completely certain. Like other quinoline derivatives, it is thought to inhibit heme polymerase activity. This results in accumulation of free heme, which is toxic to the parasites. The drug binds the free heme preventing the parasite from converting it to a form less toxic. This drug-heme complex is toxic and disrupts membrane function. The side effects of amodiaquine are generally minor to moderate and are similar to those of chloroquine. Rarely liver problems or low blood cell levels may occur. When taken in excess headaches, trouble seeing, seizures, and cardiac arrest may occur. After oral administration amodiaquine hydrochloride is rapidly absorbed,and undergoes rapid and extensive metabolism to desethylamodiaquine which concentrates in red blood cells. It is likely that desethylamodiaquine, not amodiaquine, is responsible for most of the observed antimalarial activity, and that the toxic effects of amodiaquine after oral administration may in part be due to desethylamodiaquine.

Menadione, a drug belong to class of Vitamin K, is prescribed for the treatment of hemorrhage, vitamin K deficiency, moderate to severe forms of hypoprothrombinaemia in adults and children. Menadione is a synthetic form of vitamin K, a lipid-soluble vitamin. Vitamin K is a vital cofactor for the biosynthesis of prothrombin, factor VII, IX, X, protein C and protein S. Menadione supports the functions of osteocalcin. Large doses of menadione have been reported to cause adverse outcomes including hemolytic anemia due to glucose-6-phosphate dehydrogenase deficiency, neonatal brain or liver damage, or neonatal death in some rare cases.
Quinacrine was initially developed as an anti-malarial drug marketed under the name Atabrine. Also it was approved for the teratment of ascites, however it was wothdrawn for both indication in 1995 and 2003, respectively. The drug is also used for the treatment of giardiasis, lupus, rheumatoid arthritis, refractory pulmonary effusion and pneumothorax, induce female sterilization etc. Proposed mechanisms of action include DNA intercalation interference with RNA transcription and translation, inhibition of succinate oxidation interference with electron transport, inhibition of cholinesterase, and inhibitor of phospholipase.
Adrenalone is a keton form of the natural substrate epinephrine. Adrenalone is evidently formed in vivo by hydrolytic cleavage of the diester by esterases. It is an adrenergic receptor agonist. Adrenalone inhibits the norepinephrine synthesis and dopamine beta oxidase. It is known to have very weak sympathomimetic activity when compared to adrenaline. Adrenalone has the high radioprotective effect. It is a topical nasal decongestant. Adrenalone has hemostatic, sympathomimetic and vasoconstrictor therapeutic functions.

Cinnamic acid is a polyphenol found in cinnamon oil and used in commercial flavorings. Recent studies have shown the pharmacological properties of cinnamic acid and its derivatives, including hepatoprotective, anti-oxidant, and anti-diabetic activities. In preclinical studies cinnamic acid demonstrated to be a promising candidate for the treatment ob obesity and diabetes. The mechanism of action of cinnamic acid in obesity is explained by its ability to inhibit lipases and ACE (angiotensin-converting enzyme). However, there are several hypotesis regarding the effect of cinnamic acid in diabetes: cinnamic acid enhances glucose-induced insulin secretion, prevents palmitic acid-induced lipotoxicity, inhibits palmitic acid-induced alteration of lipogenic gene and protein expression (AMPK, SREBP-1c, FAS, ACC), inhibits DPP IV, exhibits an additive effect on the uptake of glucose, stimulates adiponectin secretion, etc.

Diethyltoluamide (DEET) is an insect repellent used to keep insects away. This product is effective against mosquitoes, biting flies (gnats, sandflies, deer flies, stable flies, black flies), ticks, harvest mites, and fleas. DEET is absorbed through the skin. DEET has few adverse effects when applied as directed. The most common problem is local skin irritation, including erythema and pruritis, at the site of application.
