Embodiment 1

[0097] Example 1: 2-phenyl-8-(3,4,5-trimethoxyphenyl)-2,6-dihydro-[1,2,3]triazolo[4,5-e][ 1,4] Preparation of diazepin-5(4H)-one (compound 1)

[0098] Add 2-phenyl-4-(3,4,5-benzoyl)-5-amino-1,2,3-triazole (354mg, 1.0mmol) into a 100mL eggplant-shaped bottle, anhydrous di Chloromethane (30mL) dissolved, N 2 Protect, pre-cool at 0°C, add chloroacetyl chloride (0.15 mL, 2.0 mmol) dropwise, and transfer to room temperature after the addition is complete. The reaction was continued for 24 hours. After the reaction was detected by TLC, the solvent was evaporated under reduced pressure, washed with ethyl acetate, and filtered with suction to obtain compound I. Compound 2-chloro-N-(2-phenyl-5-(3,4,5-trimethoxybenzoyl)-2H-1,2,3-triazol-4-yl)acetamide (430mg , 1.0mmol), urotropine (701mg, 5.0mmol), ammonium acetate (386mg, 5.0mmol) was dissolved in 95% ethanol, reflux reaction for 5h, after the reaction was detected by TLC, the solvent was evaporated under reduced pressure, dichlorom...

Embodiment 2

[0099] Example 2: 2-p-tolyl-8-(3,4,5-trimethoxyphenyl)-2,6-dihydro-[1,2,3]triazolo[4,5-e] Preparation of [1,4]diazepin-5(4H)-one (Compound 2)

[0100] Compound 2 was prepared in the same manner as in Example 1 except that the corresponding raw materials were used; the yield was 74%. 1 H NMR (600MHz, CDCl 3 )δ9.61(s,1H),7.96(d,J=8.4Hz,2H),7.31(d,J=8.4Hz,2H),7.30(s,2H),4.59(s,2H),3.92( s,3H),3.89(s,6H),2.42(s,3H)ppm; 13 C NMR (100MHz, CDCl 3 )δ168.0, 162.2, 152.9(×2), 147.1, 140.8, 139.0, 137.0, 134.3, 131.7, 130.1(×2), 118.8(×2), 106.7(×2), 61.0, 57.5, 56.2(×2) ,21.1ppm.

Description

technical field [0001] The invention belongs to the technical field of medicine, and relates to a triazolodiazepin-5-one compound and its application, specifically, relates to the use of this type of compound as a tumor cell proliferation inhibitor in the preparation of antitumor drugs application. Background technique [0002] Malignant tumor is a serious disease that threatens human health and life, and it is the leading cause of death in China. Searching for and discovering new drugs for the treatment and prevention of tumors is a major issue at present. 4-Substituted methoxybenzoyl-aryl-thiazole (SMART) is a tubulin polymerization inhibitor obtained by structural optimization of natural products as lead compounds. It exerts its anticancer activity by acting on the colchicine binding site to inhibit tubulin polymerization , and it can overcome the problem of Pgp-mediated multidrug resistance, and has lower neurotoxicity compared with vinblastine. The in vivo efficacy o...
