Description
Technical Field
The invention belongs to the field of medicines, and particularly relates to a 3, 4-secolupane derivative, an optical isomer thereof or a pharmaceutically acceptable salt thereof, and application thereof in preparation of medicines for preventing and treating Cyclin D1, PLK1, FASN and GPX 4-mediated related diseases.
Background
G1/S-specific Cyclin-D1 (Cyclin D1), a Cyclin closely associated with cell proliferation. Cyclin D1 phosphorylates retinoblastoma protein Rb by binding with Cyclin-dependent kinase 4/6(CDK4/6), releases transcription factor E2F, thereby promoting deoxyribonucleic acid DNA synthesis, accelerating the transition of cell cycle from G1 phase to S phase, having the property of tumor gene, and the over-expression of Cyclin D1 can cause uncontrolled cell proliferation and malignant growth, finally forming tumor (Lakshminayana S et al, J Carcinog,2018,17(1): 7; Zhenzhain et al, 2011, 9(3): 443): 444.). Polo-like kinase 1(PLK1) is a member of the serine/threonine kinase family, and can regulate the processes of cell mitosis, cytokinesis, DNA damage response and development by interacting with various substrates through the kinase activity, and is closely related to diseases such as cancer, acute leukemia and myelodysplastic syndrome. FASN, also known as fatty acid synthase, has multiple functions and is a key enzyme for the synthesis of fatty acids. FASN is not expressed or is expressed at very low levels in normal cells or tissues, and is mainly used for synthesizing triglycerides for energy storage (Wu X et al, Adv Biol Regul,2014,54: 214-21; Menendez JA et al, Curr Opin Clin Nutr Metab Care,2006,9(4):346-57), and has important significance for controlling the fat deposition of animal bodies. The abnormal fatty acid metabolism is closely related to the occurrence and development of a plurality of diseases, which are mainly reflected in the aspects of obesity, diabetes, cancer and the like. GPX4 is a selenoprotein that can reduce lipid peroxides into corresponding lipid alcohols, inhibit the occurrence of lipid peroxidation, and is closely related to tumors, nervous system diseases, cardiovascular diseases, acute kidney injury and autoimmune diseases (Jiazhong, et al, J.Zhonghua tumor prevention and treatment, 2019,26(3): 155-161.). Studies have also found that Cyclin D1, PLK1, FASN and GPX4 are overexpressed in a variety of tumors and associated with poor tumor progression and prognosis (poliono-Alcal E et al, cancers (basel),2020,12(5): 308-15; zayteva YY et al, carcinogenisis, 2014,35(6): 1341-51; Liu H et al, Biochemistry,2018,57(14):2059-2060.), and that inhibition of them reduces the tumorigenicity in tumor cells, making Cyclin D1, PLK1, FASN and GPX4 promising targets for anti-tumor therapy.
Lupane type triterpenes and their saponins are mainly distributed in plants of Leguminosae, Araliaceae, Cucurbitaceae, Caryophyllaceae, Umbelliferae, Betulaceae, Oleaceae, and Celastraceae. Modern pharmacological studies show that the compounds have the effects of resisting inflammation, tumors, viruses, oxidation and bacteria, improving immunity (AMIRI S and the like, Biotechnol Adv,2020,38: 107409; Bian X and the like, RSC Adv,7(66): 41640-. In recent years, more and more structurally complex, novel lupane-type triterpenoids have been discovered. The discovery and activity research of novel triterpene compounds with different positions on a framework, such as substitution, ring cleavage, carbon degradation, rearrangement and the like, and complex triterpene saponins connected by a plurality of sugars has become a research hotspot of natural product research.

Example 28: pharmacokinetic testing
Animal experiments: 24 SD rats, male and female halves (7-8 weeks old, 200-220g body weight) were selected for this study. The groups were randomized into 6 groups of 4 individuals. The same dose (20mg/kg) of drug was injected intravenously or gavaged to evaluate the pharmacokinetic properties of the test drug in vivo.
Rats were fed standard conditions and were given maintenance feed at 12h day/12 h night. The test drug is formulated with 0.5% sodium carboxymethylcellulose or dimethyl sulfoxide. The same dose of lupane derivatives was injected intravenously and gavaged into rats, respectively. Collecting blood from tail vein at 0, 0.083, 0.25, 0.5, 1,2, 3,4, 6, 8, 12, and 24 hr after administration, centrifuging at 5000rpm for 15min at 4 deg.C, separating blood plasma and red blood cells, and adding heparin and freezing at-20 deg.C.
The concentration of each compound in plasma was measured by LC-MS/MS. Pharmacokinetic parameters were calculated based on the plasma concentration of each animal at different time points.
And (4) conclusion: the plasma pharmacokinetics results show that each secolupane derivative of the invention has better pharmacokinetic properties.
