Preparation of the TC-E-5003–ethyl oleate suspension and NBCA implant preparation N,N′-(Sulfonyldi-4,1-phenylene)bis(2-chloroacetamide) (TC-E-5003) is a selective protein arginine methyltransferase 1 (PRMT1) inhibitor (IC50 = 1.5 μM), and it has not been applied to tumor therapy alone, although it has the anticancer efficacy for a wide spectrum of cancer (MCF-7 breast cancer and LNCaP prostate cancer cells). This evidence concerns the gene PRMT1 and breast carcinoma.
