-
Paragraph 0111; 0135-0137, (2019/12/25)
The invention belongs to the field of drug synthesis, and specifically relates to a series of novel peptide borate compounds or pharmaceutical salts thereof, and a preparation method and pharmaceutical application thereof. The structure of the peptide borate compounds or the pharmaceutical salts thereof is as shown in a formula I which is described in the specification. The compounds of the invention can be used for preparing proteasome inhibitors, and thus can be further used for treating solid tumors and blood tumors.
