Activity of antioxidant enzymes in hepatocytes of mice with lymphoma under the action of thiazole derivative in complex with polymeric nanocarrier
Abstract
Many chemotherapeutics drugs have low water solubility, which potentially can decrease their anticancer potential. The use of drug delivery systems has proven to be highly effective in addressing the challenges associated with delivering hydrophobic chemotherapy drugs to tumor tissues. However, two major issues that arise in the clinical nanoparticle-based treatment of cancer are hepatotoxicity and suppression of the hematopoietic system, which can limit their medical applicability. As previously established, thiazole derivative N-(5-benzyl-1,3-thiazol-2-yl)-3,5-dimethyl-1-benzofuran-2-carboxamide in complex with polymeric nanocarriers (nanomicelles) based on polyethylene glycol exhibited a greater level of cytotoxicity towards specific tumor cell lines melanoma, glioblastoma, hepatocarcinoma, leukemia, etc. This compound and its complexes with polymeric nanomicelle significantly changed the activity of antioxidant enzymes in lymphoma cells. Therefore, the purpose of this study was to examine the impact of a thiazole derivative with polymeric nanomicelles based on polyethylene glycol on the hepatocytes (liver cells) of mice that had been implanted with Nemet-Kelner lymphoma. The investigated compounds thiazole derivative, polymeric nanomicelle, and combination of thiazole derivative with nanomicelle at a final concentration of 10 μM were added to the liver samples and incubated for 10 min. The activity of antioxidant defense system enzymes such as superoxiddismutase, catalase, glutathionperoxidase was determined in liver homogenate under the action of studied compounds in vitro. It was reported that neither thiazole derivative, nanomicelle, nor their complex changed the activity of antioxidant enzymes in hepatocytes from mice with lymphoma. Thiazole derivative and it complex with nanomicelle had limited negative side effects in the mice with lymphoma. The investigated compounds were not hepatotoxic toward murine liver cells.
