Abstract
Description
Technical Field
[0001] This application relates to 4-amine-2,7-disubstituted quinazoline derivatives, synthesis methods, applications, and drugs, belonging to the fields of chemistry and pharmaceuticals. Background Art
[0002] Among the histone modifications before transcription, lysine methylation has been the most widely studied. Histone lysine methylation modification is one of the causes of epigenetic changes. Enzymes that regulate lysine methylation are mainly divided into two categories: histone lysine methyltransferases (HKMTs) and histone lysine demethylases (HKDMs). HKMTs are responsible for transferring methyl groups from methyl donors to histone lysines to complete methylation modification. The function of HKDMs is mainly to remove methyl groups from histone lysines to complete the demethylation process. Their biological functions are opposite, and they jointly regulate the methylation state of histone lysines. The misregulation of histone lysine demethylases (HKDMs) is closely related to the occurrence and development of many diseases, such as senile diseases, tumors, etc. HKDMs are also related to the drug resistance of tumor drugs. Therefore, HKDMs have become an important target for the development of new anti-tumor drugs and have attracted more and more attention.
[0003] So far, two types of histone lysine demethylases (HKDMs) have been discovered: one is lysine specific demethylases (LSDs), also known as FAD (flavin adenine dinucleotide)-dependent amine oxidases, including LSD1 and LSD2. The other is JmjC (Jumonji domain-containing protein) histone demethylases, which are a family of proteins containing a Jumonji domain in the molecule. Different from LSD1, it can catalyze the demethylation of trimethylated lysine. The N-terminal and C-terminal of its family members both contain a small characteristic domain of Jumonji, called JmjN and JmjC respectively. Among them, the JmjN domain is related to transcriptional regulation, and JmjC is a component of the enzyme active center of the JmjC family. Some JmjCs containing the JmjC domain that have been discovered so far show different substrate specificities, and their demethylation catalytic process depends on the participation of Fe(II) and α-ketoglutaric acid (2-OG).
[0004] Histone demethylase is an emerging drug target. It has been less than 20 years since the discovery of the first class of histone demethylase, the LSD family. The discovery of the second class, the JmjC family, is even later. Currently, the research on the JmjC family is still in the development stage. Although various types of JmjC inhibitors have been discovered successively in recent years, most of them are derived from other targets, and inevitably have problems of selectivity and clinical efficacy. JmjC histone demethylase has gradually become an important target for studying epigenetics and has received increasing attention. Developing new JmjC inhibitors is expected to provide new ideas for anti-tumor treatment. A series of 4-amine-2,7-disubstituted quinazoline derivatives designed and synthesized in this invention have structures different from those of the JmjC histone demethylase inhibitors reported in previous studies and belong to a new type of inhibitor structure. Conducting structural modification and in-depth pharmacological research on the compounds of this invention is expected to develop new histone demethylase inhibitors. Summary of the Invention

[0016] II. Preparation method of 4-amino-2,7-disubstituted quinazoline histone demethylase inhibitors
[0017] A preparation method of a 4-amino-2,7-disubstituted quinazoline derivative. Using 2-amino-4-bromobenzoic acid (1a) as a raw material, it is cyclized with urea under high temperature conditions to obtain compound 1b, and then reacted with phosphorus oxychloride at high temperature to obtain an important intermediate 1c. Due to the high activity of the chlorine at the top of compound 1c, it will preferentially react with amines containing different substituents under high temperature and alkaline conditions to obtain a 4-substituted quinazoline intermediate (1d). 1d is coupled with boric acids with different substituents at the 7th position of quinazoline through the Suzuki reaction to obtain intermediate (1e). 1e is further subjected to a Suzuki coupling reaction to couple various groups at the 2nd position of quinazoline, or reacted with amines containing different substituents under alkaline conditions to obtain intermediate 1f. Finally, 1f is hydrolyzed with sodium hydroxide to remove the ester group to obtain a 4-amino-2,7-disubstituted quinazoline derivative I.
[0018] The synthesis route is as Figure 1 shown.

[0137] Example 51: Determination of Histone Demethylase Inhibitory Activity
[0138] 1. The determination procedure is as follows:
[0139] In the JMJD3 enzyme inhibitory activity test, GSK-J1 was used as the reference compound; in the inhibitory activity tests of other JMJD subfamily enzymes, pyridine-2,4-dicarboxylic acid (2,4-PDCA) was used as the reference compound. The primary screening was to test the repeated inhibition rates at a single compound concentration (50 μM). For IC 50For the calculation, 5 concentrations were tested for each compound, with the starting concentration being 50 μM and a 5-fold dilution gradient. The substrate solution was prepared by adding the peptide, ascorbic acid, 2-OG, and Fe(II) to 1x experimental buffer. 5 μL of the enzyme solution was transferred to the assay plate of the compound mixture and incubated at room temperature for 15 minutes. 5 μL of the substrate solution was added to each well and incubated at room temperature for 60 minutes. 15 μL of the acceptor solution and the donor solution were added to 1x Alphalisa buffer and incubated at room temperature in weak light for 60 minutes, and the endpoint was read using an EnSpire in Alpha mode. Curve fitting calculation was performed using formula (1): Inh% = (Max - Signal) / (Max - Min)*100 to calculate the inhibition rate. Using formula (2): Y = Bottom + (Top - Bottom) / (1 + 10 ∧ ((LogIC 50 -X)*HillSlope)) to fit the data in GraphPad to obtain the IC 50 value. (Where Y is the inhibition rate %, and X is the compound concentration)

[0142]
[0143]
[0144] 38 of these compounds were selected for the KDM6B enzyme inhibitory activity test. The results in Table 1 show that 30 compounds have a certain degree of inhibitory activity against the KDM6B enzyme, and among them, 3 compounds, A31, A38, and A40, have significant inhibitory activity (IC 50 values are in the range of 1.8 - 4.0 μM).
[0145] Table 2. Inhibitory activities of some compounds against other KDM subfamilies
[0146]
[0147] Some compounds with better activities were selected to test their inhibitory activities against other subtypes of the JMJD enzyme, and the results are shown in Table 2. Some compounds also have a certain degree of inhibitory effect on other JMJD subfamilies. Among them, compounds A31 and A40 show good enzyme-selective inhibition against JMJD3, showing better selectivity than GSK-J1. This type of compound shows good development prospects.
