Status:

First approved in 1952
Class (Stereo):
CHEMICAL (ABSOLUTE)
Conditions:
Aminopterin is a synthetic derivative of pterins with antineoplastic and immunosuppressive properties. As a folate analog, aminopterin competes for the folate binding site of the enzyme dihydrofolate reductase, thereby blocking tetrahydrofolate synthesis, and resulting in depletion of nucleotide precursors and inhibition of DNA, RNA and protein synthesis. Aminopterin was marketed by Lederle Laboratories (Pearl River, New York) in the United States from 1953 to 1964 for the indication of pediatric leukemia. The closely related antifolate methotrexate was simultaneously marketed by the company during the same period. Aminopterin was discontinued by Lederle Laboratories in favor of methotrexate due to manufacturing difficulties of the former. During the period Aminopterin was marketed, the agent was used off-label to safely treat over 4,000 patients with psoriasis in the United States, producing dramatic clearing of lesions. The use of aminopterin in cancer treatment was supplanted in the 1950s by methotrexate due to the latter's better therapeutic index in a rodent tumor model. Now in a more pure preparation and supported by laboratory evidence of superior tumor cell uptake in vitro, aminopterin is being investigated in clinical trials in leukemia as a potentially superior antifolate to methotrexate.

Resveratrol, a natural non-flavonoid polyphenol, exhibits a wide range of beneficial properties as an anticancer agent, a platelet anti-aggregation agent, and an antioxidant, as well as its anti-aging, anti-inflammatory, antiallergenic. This compound is in phase III clinical trials in combination with carboxymethyl-β-glucan for improving nasal symptoms in children with pollen-induced allergic rhinitis. Also in phase III clinical trial in the treatment of painful knee osteoarthritis and in type 2 diabetic patients. It has been demonstrated that resveratrol may prevent type 2 diabetic by targeting Sirtuin type 1 (SIRT1), indicating that SIRT1 may be a novel therapeutic target for diabetes prevention.
