Description
Technical Field
The invention belongs to the field of pharmacology, and particularly relates to a new application of a compound of acevalerian.
Background
Cancer or tumor, which is a malignant lesion originated from human epithelial or leaf tissue, has biological characteristics of abnormal cell differentiation and proliferation, growth loss control, infiltration and metastasis, and the like, and the occurrence of the cancer is a complex process with multiple factors and multiple steps. Tumors can originate from almost all tissue and organs and can therefore form common different tumors, such as lung cancer, breast cancer, brain cancer, liver cancer, prostate cancer, kidney cancer, blood cancer, and the like. The malignant tumors are serious diseases seriously threatening the physical and mental health of people in China, and the investigation of main death reasons of urban and rural residents published by the ministry of health in China in 2006 shows that: the number of people who die of malignant tumors in China is nearly 200 thousands, the malignant tumors become the first cause of death, but most of tumors have no effective cure measures at present. The research of malignant tumor medicine with good curative effect and low toxic and side effect is one of the important contents of the national medium and long term scientific and technical development planning compendium.
While the occurrence of malignant tumors is closely related to the changes in various molecular events. For example, Multiple Myeloma (MM) is a terminally differentiated malignant B-cell tumor characterized by abnormal proliferation of plasma cells in the bone marrow, secretion of monoclonal immunoglobulins or fragments thereof, and induction of tissue or organ damage. The vast majority of B cell tumors are mainly characterized by immunoglobulin heavy chain gene (IgH) switch region rearrangement, antigen selection, high frequency somatic mutation in B cells at the germinal center or the postgerminal center, and immunoglobulin gene regulation, which in turn will selectively act on VDJ and switch region sequences of immunoglobulin (Ig) genes to generate IgH translocation. Multiple myeloma IgH translocations are also caused by errors in IgH switch domain recombination or by high frequency somatic mutations during B cell maturation at the germinal center, with a maximum of 5 associated chromosomal sites: 4p16 (histone methyltransferase-multiple myeloma SET domain protein, MMSET and fibroblast growth factor receptor 3, FGFR3), 6p21 (cyclin D3, CCND3), 11q13 (cyclin D1, CCND1), 16q23(MAF), 20q11 (MAFB). However, in the MGUS stage (monoclonal immunoglobulin disease of unknown significance, the pre-stage of multiple myeloma), IgH translocations accumulate rarely 4p16 t (4,14) and 16q23t (14,16), which indicates that the translocations may promote the development of pathological states such as MGUS and SMM, which may eventually lead to the occurrence of multiple myeloma, or have a certain relationship with the rapid development of MGUS into multiple myeloma.
Valerian is mainly distributed in Europe, Asia, northeast China, etc., has mind tranquilizing effect, and is mainly used for treating uneasiness, cardiopalmus and insomnia, mania, noise, rheumatalgia, dysmenorrheaIt can be used for treating amenorrhea, traumatic injury, etc., and has pharmacological effects in strengthening cerebral cortex inhibiting process, reducing reflex excitability, relieving smooth muscle spasm, resisting bacteria, and promoting urination. The acevalant has a structure shown as the following formula I and a molecular formula C24H32O10And the molecular weight of 480.50, is a natural extract of valerian, and has effects of tranquilizing and relieving pain.

Example 5
To analyze the ability of acetovalosin to induce apoptosis in multiple myeloma cells, different myeloma cells (LP1, RPMI-8226, OPM2) were plated at 50000 cells per well in 96-well plates and treated with acetovalosin (0. mu.M, 2. mu.M, 4. mu.M) for 24 hours. Then cells are collected and double-stained by Annexin V-FITC and Propidium Iodide (PI), and the proportion of Annexin V positive cells is detected by a flow cytometer after 5 minutes.

Example 7
To further analyze the anti-tumor ability of the acevalosin in vivo, 5-6-week-old female Balb/C nude mice (provided by Shanghai Slac animal center) were selected, and after one week of quarantine and quarantine, subcutaneous myeloma cells LP1 and RPMI-8226 (3X 10) were performed at the medial proximal vessel of the left hind limb7Cell/cell). When the tumor grew to a palpable state (about 5-10mm in diameter), the tumorigenic nude mice were randomly divided into two groups (control group, administration group). The experimental group was administered 50mg/kg of acetylvaleric (AVT, solvent dissolved in PBS and sesame oil at a volume ratio of 1: 1) daily, the control group was administered the same volume of solvent continuously for 15 days, and changes in tumor volume were measured daily while monitoring changes in body weight of the mice.
The results are shown in fig. 7, specifically: FIG. 7A is a graph showing the relationship between the tumor volume and the number of days of administration in mice, and FIG. 7B is a graph showing the relationship between the body weight and the number of days of administration in mice. As can be seen from fig. 7: the body weights of the mice of the experimental group and the control group are not obviously changed; the Valerianin significantly inhibited the growth of tumors in two tumor-bearing mice, and the differences of the tumor volumes of the Valerianin intervention group compared with the control group were statistically significant (p < 0.01;. p < 0.001).
Example 8
To further evaluate the effect of acetovalgenin on tumor cells in patients, bone marrow cells from healthy and myeloma patients were collected, mononuclear cells were extracted from blood after isolation from lymphocyte isolates, cells were seeded in soft agar with the addition of acetovalgenin, and colonies of greater than 50 cells were counted microscopically after 1-2 weeks of culture.
The results are shown in FIG. 8, and it can be seen from FIG. 8 that the number of colonies in healthy persons and myeloma patients is substantially unchanged and the number of colonies in myeloma patients is significantly reduced after the addition of acevalosin. The acetovalerian is suggested to be capable of effectively inhibiting the proliferation and cloning of myeloma cells of myeloma patients.
