Abstract

The invention discloses an application of cinnamic acid on preparation of medicines for treating cancers. The cancers comprise a prostatic cancer, a non-Hodgkins lymphoma, spongioblastoma, oophoroma and a colorectal cancer. The cinnamic acid can effectively promote apoptosis of malignant cells, adjusts a proliferation cycle of the malignant cells and restrains proliferation of the malignant cells to a certain degree; and moreover, the cinnamic acid can act on an STAT3 signal channel, obviously reduces expression of STAT3 genes and effectively restrains growth of malignant tumors of the prostatic cancer, the non-Hodgkins lymphoma, the spongioblastoma, the oophoroma and the colorectal cancer in bodies of mice. By the application of the cinnamic acid on preparation of the medicines for treating the cancers, novel medicines with antitumor activity can be conveniently researched on the aspects of cell apoptosis and tissue cell proliferation cycle, prevention and treatment on various malignant tumors which are relevant to STAT3 are researched conveniently, and a novel thinking is provided for treatment of the various malignant tumors.

Description

technical field [0001] The invention belongs to the technical field of biomedicine, and more specifically relates to the use of cinnamic acid in the preparation of medicines for treating prostate cancer, non-Hodgkin's lymphoma, glioblastoma, ovarian cancer, prostate cancer or colorectal cancer. Background technique [0002] Cinnamic acid, also known as β-phenylacrylic acid or 3-phenyl-2-acrylic acid. It is an organic acid isolated from cinnamon bark or benzoin. It is mainly used in flavors and fragrances, food additives, pharmaceutical industry, beauty, pesticides, organic synthesis, etc. [0003] Malignant tumors, as one of the largest public health problems in the world, have greatly endangered human health, and have gradually become the number one killer of human beings in today's era. The occurrence and progress of different malignant tumors are very different, but they also have a common feature, that is, the occurrence and development of tumors are largely not only th...
