suramin

 [soo´rah-min]
an antifilarial and antiprotozoal agent used as the hexasodium salt in prophylaxis and treatment of early stages of African trypanosomiasis and sometimes onchocerciasis. Because of its toxicity it must be used with care.

suramin

A derivative of urea which has currency as an antiparasitic and been used to manage trypanosomiasis and onchocerciasis. Suramin was evaluated by the US National Cancer Institute for managing prostate cancer, but was dropped from its research in 2008.

Suramin has been used by alternative health practitioners as a cancer therapy, based on its ability to block enzyme activity and the production of growth factors. It has been used for leukaemia, as well as cancers of the adrenal cortex, breast, kidney and prostate; its effect may be enhanced by adding tumour necrosis factor and/or interferon-gamma to the therapeutic regimen.

The mice were randomly divided into four groups (n = 3 ~ 5 mice) as follows: (i) mice sensitized with phosphate-buffered saline (PBS) and challenged with OVA (control group); (ii) mice sensitized with OVA plus LPS and challenged with OVA (asthma group); (iii) mice sensitized with OVA plus LPS and treated with 20 [micro]L PBS at 30 min before the same challenge with OVA (vehicle group); and (iv) mice sensitized with OVA plus LPS and treated with suramin (Sigma-Aldrich) at 30 min before the same challenge with OVA (suramin group).
The inhibition by the treatments with suramin (P2-receptor antagonist, 100 [micro]M), apyrase (ATP-hydrolyzing enzyme, 20 U/mL), and CBX (hemichannel blocker, 100 [micro]M) suggested the contribution of ATP signaling in this process.

Naviaux, MD tested the effect of suramin, used to treat trypanosomiasis or African sleeping sickness, a parasitic disease and found that suramin blocked the extracellular signaling pathway used by ATP and other mitokines in a mouse model of autism spectrum disorder (ASD), ending the cell danger response and related inflammation.
