Embodiment 1

[0037] Example 1: Detection of survival rate by SRB method after SCM treatment of A549 cells.

[0038] (1) The compound SCM was added to treat the cells previously seeded in a 96-well plate. (2) After compound treatment for 24 hours and 48 hours, the old culture medium was discarded, 100 μL of trichloroacetic acid was added, and the cells were fixed at 4° C. for 1 hour. (3) Discard the fixative. Wash five times with double-distilled water in gentle motions, and dry at room temperature. (4) Add 50 μL of SRB to each well, shake at room temperature for 10 minutes. (5) Wash 5 times with 1% acetic acid and dry at room temperature. (6) Add 100 μL Tris base in non-buffer solution with a concentration of 10 mM / L to each well and place on a shaker for 10 minutes. (7) Select 540nm excitation light to measure OD value.

[0039] The results showed that: 5, 10, 20μM SCM treatment of A549 cells for 24h and 48h can significantly inhibit the survival of A549 cells, see figure 1 .

Embodiment 2

[0040] Example 2: After SCM treatment of A549 cells, the changes in cell morphology were detected under an inverted microscope.

[0041] A549 cells were seeded in a 6 cm-diameter petri dish at 37°C in CO 2 After culturing in the incubator for 12 hours, SCM was added for 3 hours, 6 hours, 12 hours, and 24 hours, and then the cell morphology was photographed under an inverted microscope.

[0042] The results showed that: under the above conditions, SCM could reduce the number of A549 cells and promote the release of apoptotic bodies. See figure 2 .

experiment example 3

[0043] Experimental Example 3: A549 cells were treated with SCM for 24 hours, and the apoptosis was detected by western blot.

[0044] A549 cells were seeded in a 6 cm-diameter petri dish at 37°C in CO 2 After culturing in the incubator for 12 hours, add SCM for 24 hours, lyse the cells, collect the cell lysate, centrifuge at 12000g for 15 minutes at 4°C, take the supernatant, and use western blot to detect the level of PARP protein cleavage in different cells.

[0045] The results showed that: after treating A549 cells with 1, 5, and 10 μM SCM for 24 hours, they can significantly promote the cleavage of PARP protein, so SCM can significantly promote the apoptosis of A549 cells. See image 3 .

Abstract

The invention discloses application of compound (E)-2-(5,5-dimethyl-3-(4-(piperazin-1-yl)styrene)cyclohex-2-ene-1-methylene)malononitrile in drugs to inhibit the growth of A549 cancer cells and promote A549 apoptosis and autophagy; the dose of the drugs to effectively promote A549 apoptosis and autophagy is 5-10 mu M. The compound provided herein is expectedly applicable as an effective tool to inhibit tumor growth, and basis is laid for the development of non-small lung cancer therapeutics.

Description

technical field [0001] The invention relates to the application of styryl cyclohexallyl dinitrile derivatives in the preparation of anti-lung cancer drugs, in particular to the fluorescent compound (E)-2-(5,5-dimethyl-3-(4-(piperazine) -1-yl)styrene)cyclohex-2-ene-1-methylene)malononitrile (abbreviated as SCM) in inhibiting the growth of A549 cancer cells and promoting the application of A549 cell apoptosis and autophagy drugs. Background technique [0002] Lung cancer is the leading cause of cancer-related death worldwide. About 85% of lung malignancies are non-small cell lung cancer. In recent years, great progress has been made in the prevention and treatment of lung cancer, but the diagnosis of non-small cell lung cancer is seriously lagging behind, and it is often diagnosed at an advanced stage with a poor prognosis. Conventional chemotherapy and radiotherapy can achieve the greatest therapeutic effect. Small molecule compounds can act as tumor suppressors, becoming ...
