[0316] Step 1: Intermediate 1.1(298mg, 0.79mmol), 2- allyl -6- (methylthio) -1H- pyrazolo [3,4-d] pyrimidine -3(2H)- one (137mg, 0.72mmol), N,N'- dimethylethylenediamine (N-dimethylethylenediamine) The reaction solution was cooled to room temperature and filtered. The filter cake was washed with ethyl acetate. The filtrates were combined and concentrated under reduced pressure. The residue was purified by prep-TLC (petroleumether / ethyl acetate = 1 / 1) to obtain compound 1(270mg) as yellow oil. m / z:[M+H] + 399.2。
[0317] Step 2: m-chloroperoxybenzoic acid (71mg, 0.35mmol) was added to the toluene (5mL) solution of Compound 1(70mg, 0.18mmol). After the reaction solution was stirred at room temperature for 1 hour, 4-(4- methylpiperazine) aniline (67mg, 0.35mmol) and N,N- diisopropylethylamine (45mg) The reaction system...
[0334] Using the synthetic method of compound 1-1, using intermediates 1.1, 1.3, 1.13, 1.2, 1.4, 1.10, 2.1, 2.2, 2.15, 3.1 and 4.34 as starting materials, the 4-(4- methylpiperazine) aniline in step 2 was replaced with 3- methoxy-4-.

Abstract
The invention relates to a pyrazolo[3, 4-d]pyrimidin-3-one derivative as shown in a formula (I) and / or pharmaceutically acceptable salt thereof, a composition containing the compound as shown in the formula (I) and / or pharmaceutically acceptable salt thereof, a preparation method of the derivative, and an application of the derivative as Wee1 and / or PLK1 inhibitors and as sensitizers for chemotherapy or radiotherapy of cancer. The pyrazolo[3, 4-d]pyrimidin-3-one derivative disclosed by the invention can effectively inhibit Wee1 and / or PLK1 and related signal channels, and has a good effect of treating and / or relieving cancers.
Description
Technical field [0001] The invention relates to a pyrazolo [3,4-d] pyrimidine -3- one derivative and its pharmaceutically acceptable salt which can inhibit Wee1 and / or PLK1 and its signal pathway, a pharmaceutical composition containing the derivative and its pharmaceutically acceptable salt, and the application of the derivative and its pharmaceutically acceptable salt in treating diseases mediated by Wee1 and / or PLK1 and preparing medicines for treating diseases mediated by Wee1 and / or PLK1. technical background [0002] Wee1(Wee1 G2 detection point kinase; Gene number: 7465) and PLK1(polo-like kinase 1; Gene number: 5347) is a member of serine / threonineproteinkinase family. [0003] Wee1 can directly phosphorylate cyclin-dependent kinase 1(CDK1), and the phosphorylation site is tyrosine 15 residue of CDK1, which is an inhibitory phosphorylation site and negatively regulates CDK1 activity. The activation of G2 detection point is mainly through inhibiting mitosis and promoting...
