Embodiment 1

[0075]

[0076] Methyl 3-((7-(3-methoxyphenyl)-5-methyl-6-((4-methylpyridin-3-yl)carbamoyl)-4,7-dihydro-[1 ,2,4]Synthesis of triazol[1,5-a]pyrimidin-2-yl)thio)propionate (2a)

[0077] Step 1: Preparation of methyl 3-((5-amino-1H-1,2,4-triazol-3-yl)thio)propionate (intermediate 1)

[0078] Methyl 3-bromopropionate (14.36g, 0.086mol) was dissolved in 40ml of absolute ethanol for later use. In a 500ml reaction vessel, NaOH (3.44g, 0.086mol) was dissolved in 200ml of purified water and stirred until completely dissolved. 3-Amino-5-thio-1,2,4-triazole (10.00 g, 0.086 mol) was then added and stirred. After 30 minutes, a mixture of methyl 3-bromopropionate and ethanol was added. React overnight at room temperature. After the reaction was complete, it was extracted with ethyl acetate, washed with saturated sodium chloride and washed with Na 2 SO 4 dry. Methyl 3-((5-amino-1H-1,2,4-triazol-3-yl)thio)propanoic acid (11.65 g, yield 67%) was obtained.

Abstract

The invention discloses a triazolopyrimidine compound, a preparation method and application thereof. The triazolopyrimidine compound is an mTOR inhibitor with a novel structure, the lead compound hasa new compound skeleton found by using a virtual screening and pharmacophore method, and targeted design is carried out according to different PI3K and mTOR protein structures. Therefore, the lead compound has the characteristics of high activity and high selectivity. Moreover, the compound is creatively used as a radiosensitizer for cancer treatment, so that the sensitivity of cancer cells to radiotherapy can be improved, the radiation dose in radiotherapy is greatly reduced, the side effect is reduced, and the radiotherapy effect is improved.

Description

technical field [0001] The invention relates to the technical field of medicine and chemical industry, in particular to a triazolopyrimidine compound and its preparation method and application. Background technique [0002] Rapamycin (mTOR) is a serine / threonine protein kinase with a molecular weight of about 280kda. It plays an important role in a variety of signaling pathways and affects a variety of physiological functions, such as growth, proliferation, protein synthesis, autophagy, metabolism, and survival. Excessive activation of mTOR is one of the important reasons leading to excessive proliferation and malignant transformation of cells, while inhibiting mTOR activity can achieve anti-tumor, anti-inflammatory, immunosuppressive and anti-aging effects. [0003] Advanced liver cancer (Hepatocellular carcinoma) is a very terrible disease. Due to the resistance of liver cancer cells to cellular chemotherapy and individual differences in patients' sensitivity to molecular...
