Kinase experiment:

The ATPase assay is performed in a 10 μL reaction mixture containing 20 mM Tris-HCl (pH 7.5), 1 mM DTT, 8 mM MgCl2, 5 μM M13 circular ssDNA, 2.5 μM RecA from the specified bacterial species and increasing concentrations of suramin. The reaction is initiated by the addition of 2 mM [α-32P]ATP, incubated for 30 min at 37°C and stopped by the addition of 25 mM EDTA[2].

Animal experiment:

Rats: To assess the potential preventive and curative effects of suramin, rats are randomly divided into four groups after MCT injection. In the preventive strategy, the treatment is started on the first day, and one group receives 10 mg/kg suramin intravenously twice weekly for 3 weeks, while a second group receives only the vehicle at the same time points. To assess the potential curative effects of suramin, rats are given MCT and are left untreated for 21 days before being randomly divided into two groups that are subsequently treated with either suramin or vehicle from day 21 to day 42 inclusive. The effect of suramin on survival is evaluated from the day 21 of MCT injection to day 42 corresponding to the treatment period[4].

Suramin is a polysulfonated naphthylurea that inhibits the binding of calmodulin to recognition sites on the ryanodine receptor-1 (IC50 = 4.9 μM), blocks G protein coupling to GPCRs, and non-selectively antagonizes P2 purinergic receptors (10-100 μM).[1],[2[ Suramin also acts as a non-specific competitor of glycosaminoglycan binding to a variety of targets including TGFβ, PDGF, and FGF and additionally inhibits insulin-like growth factor-l, EGF, PKC activity, TNF, IL-2, transferrin, and Apo-B.[3] While originally used as an early stage treatment of trypanosome-caused onchocerciasis (African river blindness) and African trypanosomiasis (African sleeping sickness), suramin has been under clinical evaluation for its potential to regress a number of cancer cell lines, including non-small cell lung cancer, advanced breast cancer, hormone refractory prostate cancer, metastatic renal cell cancer, colorectal cancer, and high-grade gliomas.[3],[4],[5]
