Problems solved by technology

However, in the research field of histone lysine methyltransferase inhibitors, most studies mainly focus on histone lysine methyltransferases such as EZH1 and EZH2, DOT1L, SETD7, EHMT1 and EHMT2. There are relatively few studies on histone methyltransferases that are closely related to the occurrence and development of human tumors

Embodiment Construction

[0019] In order to confirm the antitumor effect of the compound of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific examples.

[0020] 1. Experimental method

[0021] 1.1 Receptor-based virtual screening

[0022] first use The protein preparation module Protein Preparation Wizard in the software package processes the crystal structure of NSD3 (PDB: 4YZ8). The ChemDiv database was preprocessed with Discovery Studio 2.5, including deduplication, removal of salt ions and inorganic substances, and structural standardization. use The LigPrep module in 9.0 generates probable ionization states and tautomers of compounds at pH = 7.4.

[0023] Before using the molecular docking method for virtual screening, it is first necessary to verify the effectiveness of the Glide docking method used, define the active site of NSD3, and set the center of mass of the ligand molecule S-adenosyl methionine (S...

Abstract

The invention discloses a compound A8 used as a histone transmethylase NSD3 activity inhibitor and a medicine purpose thereof. The compound A8 has a chemical structure shown as a formula I in description, and the chemical name is 6-amino-9-(2-(p-tolyloxy)ethyl)-9H-purine-8-thiol. The medicine purpose refers to the preparation of anti-tumor medicine by using at least one of the compound A8 or hydrates, pharmaceutically acceptable salt, dynamic isomers, stereoisomers and precursor compounds as active ingredients. Experiments show that the compound A8 can effectively inhibit the NSD3 enzyme activity; the enzyme level IC50 value is 0.69+ / -0.06mumol / L; the growth and proliferation of a non-small-cell lung cancer cell line H460 can be obviously inhibited. The compound has the effect of inhibiting the tumor cell proliferation, is hopeful to being used as an active ingredient for preparing the anti-tumor medicine and has medicine prospects.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a histone methyltransferase NSD3 activity inhibitor and application thereof. Background technique [0002] Histone methylation is one of the most important modification mechanisms of epigenetic modification. The abnormal expression of histone methylation and its regulator histone methyltransferase is closely related to the occurrence of genetic diseases, autoimmune diseases, aging and cancer, especially in the occurrence and development of tumors. Therefore, histone methyltransferases are regarded as potential new targets for anti-tumor therapy. [0003] In recent years, breakthroughs have been made in the development of inhibitors targeting histone methyltransferases. Currently, the histone methyltransferase EZH2 inhibitor EPZ-6438 (Epizyme Company) entered phase I / II clinical trials in 2014 for the treatment of patients with non-Hodgkin's lymphoma, advanced solid...
