Abstract

The present invention provides selective HER2 inhibitors. Specifically, the invention provides a compound shown as a formula I or pharmaceutically acceptable salt thereof, wherein each group variable is defined as in the specification.

Description

Selective HER2 inhibitors

Technical Field

The invention belongs to the field of medicines, and particularly relates to a selective HER2 inhibitor.

Background

HER2 (also known as ErbB 2) and HER2 mutagen have become therapeutic targets for many cancers. HER2 small molecule kinase inhibitors, which have been marketed and under development, generally have inhibitory effects on other pathways (e.g., EGFR). Therefore, side effects such as rash, diarrhea, etc. are caused. HER2 inhibitors with brain penetration function have particular application to patients with brain metastases. The only marketed selective HER2 small molecule kinase inhibitor, tucatinib, is undergoing many combined clinical studies due to its activity. Furthermore, new ADCs for HER2, such as T-DM1 and T-DXd, although having good potency, inevitably produce drug resistance and have poor brain penetration function.

In view of the foregoing, there is a strong need in the art to develop more excellent, highly selective inhibitors of HER2 small molecule kinase that have no inhibitory effect on EGFR to meet clinical demands.

9) Chemiluminescent signal values were read using Envision and data collected.

3.3. Data analysis

1)Z’factor＝1-3*(SDMax+SDMin)/(MeanMax-MeanMin)

2)Z’factor＝1-3*(SDMax+SDMin)/(MeanMax-MeanMin)

3)CVMax＝(SDMax/MeanMax)*100％

4)CVMin＝(SDMin/MeanMin)*100％

5) Experimental window = signal value/background value

6) Negative control: 0.1% DMSO

7) Positive control 1,000nM lenatinib

8) Compound IC50 was calculated using GraphPad nonlinear fit formula:

Y＝Bottom+(Top-Bottom)/(1+10^((LogIC50-X)*HillSlope))

x is the log value of the compound concentration; percentage of inhibition Y

9)Inhibition(％)＝(1-(Cpd-MeanMin)/(MeanMax-MeanMin))×100％

100% inhibition 1,000nM lenatinib; 0% inhibition ratio 0.1% DMSO
