The present invention relates to a piperazine heteroaryl derivative, a preparation method therefor and the use of same in medicine. In particular, the present invention relates to the piperazine heteroaryl derivative as shown in the general formula (I), a preparation method therefor, a pharmaceutical composition comprising the derivative, and the use of same as a capsid protein inhibitor, in particular in the prevention and/or treatment of diseases such as hepatitis B, influenza, herpes, AIDS, etc. The definitions of each group in the general formula (I) are the same as those defined in the description.
Capsid assembly modulators (CpAMs) represent a new class of antivirals targeting hepatitis B virus (HBV) core protein to disrupt the assembly process. In this work, a novel chemotype featuring a fused heterocycle amide was discovered through pharmacophore exploration. Lead optimization resulted in compound 8 with an EC50 value of 511 nM, and then methyl substitution on the piperazine was found to improve
