Diethylcarbamazine is used in humans, dogs and cats for the treatment of parasitic infections, including pulmonary eosinophilia, loiasis, and lymphatic filariasis. The exact mechanism of its action is unknown, however some studies showed the involvment of inducible nitric-oxide synthase and the cyclooxygenase pathway. Although there is no information on whether the drug is marketed in the USA and Europe, it is currently used in India.

Conditions:
Cyclamic acid (Cyclamate) is banned in the United States but it is used in many other Western countries without safety concerns. Cyclamate interacts with the sweet taste receptor subunit T1R3 transmembrane domain. Initially it was recommended for use in treatment of obese patients and by individuals with diabetes but in August 27, 1970 FDA concluded that there was no substantial evidence of effectiveness of cyclamate compounds at any level for treatment of obese patients and individuals with diabetes and therefore prohibited continued sale of cyclamate containing products with drug labeling. cyclamate is the putative carcinogenic agent. Cyclamate was tested in the Maximal Electroshock Seizure model (mice, ip), showing moderate anticonvulsant activity.

Class (Stereo):
CHEMICAL (ABSOLUTE)
Conditions:
Chloramphenicol is a broad-spectrum antibiotic that was first isolated from
Streptomyces venezuelae in 1947. The drug was subsequently chemically synthesized. It has both a bacteriostatic and bactericidal effect; in the usual therapeutic concentrations it is bacteriostatic. Chloramphenicol is used for the treatment of serious gram-negative, gram-positive, and anaerobic infections. It is especially useful in the treatment of meningitis, typhoid fever, and cystic fibrosis. It should be reserved for infections for which other drugs are ineffective or contraindicated. Chloramphenicol, a small inhibitor of bacterial protein synthesis, is active against a variety of bacteria and readily enters the CSF. It has been used extensively in the last decades for the treatment of bacterial meningitis. In industrialized countries, chloramphenicol is restricted mostly to topical uses because of the risk of induction of aplastic anemia. However, it remains a valuable reserve antibiotic for patients with allergy to β-lactam antibiotics or with CNS infections caused by multiresistant pathogens.

Conditions:
Thiphenamil, an antispasmodic drug with a local anesthetic activity, inhibits contraction. The clinical trials have shown that thiphenamil could suppress upper urinary tract contractility, and was suggested to use the drug for renal colic and stone management. In addition, this drug was studied for the treatment of detrusor incontinence in patients with detrusor instability. The results showed, that the drug caused a significant decrease in problems due to loss of urine when the patient was taking the drug compared to the placebo.

Piperazine, a six membered nitrogen containing heterocycle, is of great significance to the rational design of drugs. This moiety can be found in a plethora of well-known drugs with various therapeutic uses, such as antipsychotic, antihistamine, antianginal, antidepressant, anticancer, antiviral, cardio protectors, anti-inflammatory, and imaging agents. Slight modification to the substitution pattern on the piperazine nucleus facilitates a recognizable difference in the medicinal potential of the resultant molecules. Piperazine has been used as an antihelmintic drug. Piperazine works by paralyzing the worms. They are then passed in the stool.

Conditions:
Adenosine monophosphate (AMP) is a nucleotide, consisting of a phosphate group, the sugar ribose, and the nucleobase adenine. AMP is an activator of several enzymes in the tissues. In the glycolytic pathway, the enzyme phosphofructokinase is inhibited by ATP but the inhibition is reversed by AMP, the deciding factor for the reaction being the ratio between ATP and AMP. In medicine, AMP is used mainly as an alternative to adenosine for treatment of ischemia and as a tool compound to measure hyperresponsiveness of airways.
