Nitrogen-containing heterocyclic compounds with MYT1 inhibitory activity

Abstract

A novel compound having MYT1 inhibitory activity, or a salt thereof or a solvent thereof, is provided. The compound, or a salt thereof or a solvent thereof, is represented by formula (1): [wherein, R4 is selected from the group consisting of substituted C6-C10 aryl (R4A), substituted 4-10 member heterocyclic groups, and substituted 5-10 member heteroaryl (R4HA); R5 and R6 together with the atoms bonded thereto form a substituted D ring; the D ring is selected from the group consisting of 3-10 member monocyclic alicyclic rings, benzene rings, 3-12 member monocyclic heterocycles, and 5-6 member monocyclic aromatic heterocycles (DHA); any two adjacent substituents on the D ring together with the atoms bonded thereto form a substituted E ring].
