| Description | Suramin is a dual-function inhibitor of SARS-CoV-2 RNA-dependent RNA polymerase (RdRp) and protein tyrosine phosphatases (PTPases), with antiparasitic, anticancer, and anti-angiogenesis properties, inhibiting sirtuins and DNA topoisomerase II. |

| In vitro | Low concentrations of 35 μM (50 μg/mL) and 70 μM (100 μg/mL) Suramin were not cytotoxic to prefascial adipocytes. However, high concentrations of 105 μM (150 μg/mL) and 140 μM (200 μg/mL) showed cytotoxic effects by reducing cell viability. Suramin (0-140 μM) stimulated and promoted lipogenic differentiation of FSCs in a time - and dose-dependent manner. [1] Suramin activates Nrf2 and correspondingly inhibits the activated B cell (NF-κB) nuclear factor kappa light chain enhancer and mitogen-activated protein kinase (MAPK) pathway, thereby reducing IL-1β-stimulated chondrocyte inflammation and ECM degeneration. Suramin repolarizes M1 macrophages to M2 phenotype, further reducing apoptosis of chondrocytes. [2] |
| In vivo | Rats were intraperitoneally injected with 50 mg/kg Suramin once a week for 4 weeks, and the results showed that Suramin could slightly promote rat adipogenesis in vivo. [1] |
