描述 RRx-001 is a pleiotropic anticancer agent in phase III clinical trials, which polarizes tumor-associated macrophages from a low phagocytic M2 phenotype to a high phagocytic M1 phenotype. In vitro, RRx-001 was found to decrease the expression levels of CD47 and SIRPα on tumor cells and monocytes/macrophages, respectively, reducing the phagocytosis inhibitory function of the CD47/SIRPα interaction[1]. RRx-001 has nephro-, geno- and myeloprotective effects in vivo. Importantly, RRx-001 did not protect sarcoma-180 solid tumor xenografts against cisplatin-induced cytotoxicity[2]. RRx-001 is demonstrated to induce Nrf2 in normal tissues, mediating protection, and to downregulate the Nrf2-controlled antiapoptotic target gene, B-cell lymphoma 2 (Bcl-2) in tumors, mediating cytotoxicity[3]. Higher doses of RRx-001 (100, 1000 micro molar) significantly decreased erythrocyte deformability under hypoxia. Co-administration of RRx-001 and nitrite under hypoxic conditions results in a significant increase in erythrocyte deformability that is related to increased NO production[4].
