experiment example 1

[0040] Experimental Experiment 1. Effect of Saridin on proliferation of mouse pituitary tumor cells (ACTH secretion type, ATT-20 cells).

[0041] Experimental materials: ATT-20 cells were purchased from American Type CultureCollection. Boussarodin was purchased from SELLECK (China, Shanghai Bluemum Chemical Co., Ltd.). Dimethyl sulfoxide (DMSO) is purchased from Merck Life Sciences (Nantong) Co., Ltd. DMEM, fetal bovine serum (FBS) and Horse serum (HS) were purchased from Saimo Fel Technology (China) Co., Ltd. Pyramomycin mixture is purchased from Beijing Solabao Technology Co., Ltd. CCK-8 doses were purchased from Jiangsu Kaizi Biotechnology Co., Ltd.

[0042] Solution is formulated: Saassolin is dissolved in DMSO to a 5 mm concentration of 100 mm.

[0043] ATT-20 cells were inoculated at 96-well plates, 0.5% FBS hunger cells were added to FBS to a final concentration of 10%, and the dose of the final concentration 0, 10, 20, 40, 60, 80, 100 um was added to the Saar Luo, cultured...

[0048] Experimental Example 2. Effects of Saridin on tumor growth in mice in the skinned tumor model.

[0049] Experimental materials: BAL / BC mice were purchased from Beijing Wirong Lihua Experimental Animal Technology Co., Ltd. ATT-20 cells were purchased from American Type Culture Collection. Boussarosine, timomazolelamine and Gekinib were purchased from SELLECK (China, Shanghai Bluemum Chemical Co., Ltd.). Carboxymethylcellulose (CMC-NA) is purchased from National Medicine Group Chemical Reagent Co., Ltd.

[0050] Modeling group: 16-18g of female mice after hair removal of ATT-20 cells, 5 days after the tumor growth is 3-5mm in diameter, randomly divided into model group (1% CMC-NA), teloxazole group (20 mg · kg -1 , Positive controls), Gefitinib group (75mg · kg -1 , Negative controls) and Bunar Lotin group (50mg · kg -1 8. Each group, normal mouse with uncharged tumors.

Abstract

The invention discloses an application of Bexarotene in preparation of a medicine for resisting pituitary adrenocorticotropic hormone adenoma, the pituitary adrenocorticotropic hormone adenoma enables a patient to excessively secrete corticotropin (ACTH) for a long time, and the adrenal gland is stimulated to secrete a large amount of cortisol, so that symptoms such as centripetal obesity, osteoporosis, amyotrophy, sexual dysfunction, hypertension, insomnia and the like of patients, which belong to rare diseases, can be caused. The Bexarotene can significantly inhibit tumor growth and inhibit ACTH secretion and expression of a precursor POMC of ACTH. The Bexarotene can be used for preparing the medicine for resisting pituitary adrenocorticotropic hormone adenoma, adverse reactions are reduced, and a safe, effective and economical solution is provided for treatment and prevention of diseases.

Description

Technical field [0001] The present invention relates to the application of the preparation of drugs in the preparation of drugs, mainly involving the application of the preparation of anti-pituitary academic adrenocorticoid adenoma drugs, belonging to the technical field of medical technology. Background technique [0002] Pituitary academic adrenal hormone adenoma is a benign hormone secretory tumor that occurs in front of the pituitary, which is a rare disease. It is the main cause of Kutin disease. [0003] Pituitary academic adrenocorticoid adenoma causes the patient's pituitary pituitary leaf long-term secretion of ACTH, stimulates the adrenal cortex to produce excess cortisol, and the clinical manifestation is Kukin syndrome, the pathological changes include, but is not limited to, to the heart, buffalo, hair, hair increase, hair increase, Skin muscle atrophy, nervous system injury, hypertension, atherosclerosis, diabetes, immune injury and sexual dysfunction. [0004] Pitu...
