The influence of a new dihydroquinoline type antioxidant on doxorubicin-induced hepatic toxicity was studied in mice (CFLP, LATI). Four groups of mice were studied: control, doxorubicin-treated, 5,6-methylen-bis (2,2,4/-trimethyl-1,2-dihydroquinoline/-disulphate (MDS)-treated, as well as doxorubicin and MDS-treated groups. Doxorubicin (15 mg/kg) was administered intraperitoneally, the MDS solution was given by a gastric tube. Liver function was assessed by the serum glutaminic-oxaloacetic-transaminase (SGOT) reaction. The lipid peroxidation in liver tissue was determined by the rate of malondialdehyd (MDA) production, the permeability of the liver lysosomal membrane was established by measuring beta-glucuronidase activity and its release from the cells. The MDS treatment proved to be effective in significantly reducing SGOT elevation, MDA production and lysosomal membrane damage in hepatic tissue. Clinical trials seem to be justified in using antioxidative substances to control doxorubicin toxicity.

Chronic myelomonocytic leukemia (CML) is a myeloid tumor characterized by MDS (myelodysplastic syndrome) and MPN (myeloproliferative neoplasms). Allogeneic hematopoietic stem cell transplantation, chemotherapy, interferon, and targeted therapy are the main treatment methods for CML. Tyrosine kinase inhibitors (TKIs) are also a treatment option, and patients are currently recommended to take these drugs throughout their lives to prevent CML recurrence. Therefore, there is a need to investigate and identify other potential chemotherapy drugs. Currently, research on CML treatment with a single drug has shown little progress. Fingolimod (FTY720), an FDA-approved drug used to treat relapsing multiple sclerosis, has also shown great potential in the treatment of lymphocytic leukemia. In our study, we find that FTY720 and curcumol have a significant inhibitory effect on K562 cells, K562/ADR cells, and CD34+ cells from CML patients. RNAseq data analysis shows that regulation of apoptosis and differentiation pathways are key pathways in this process. Besides, BCR/ABL-Jak2/STAT3 signaling, PI3K/Akt-Jnk signaling, and activation of BH3-only genes are involved in CML inhibition. In a K562 xenograft mouse model, therapy with curcumol and FTY720 led to significant inhibition of tumor growth and induction of apoptosis. To summarize, curcumol and FTY720 synergistically inhibit proliferation involved in differentiation and induce apoptosis in CML cells. Therefore, synergistic treatment with two drugs could be the next choice of treatment for CML.
