Compound with heat shock heat protein 70 inhibitory activity and application thereof

Abstract

The invention belongs to the technical field of medicines, and particularly provides a compound with heat shock protein 70 inhibitory activity and application thereof. The compound comprises at least one of three compounds in the specification. The compound provided by the invention has weak reaction capacity to glutathione and strong binding capacity to heat shock protein 70, and has high activity and low side effect in a complex biological system, so that the compound can be used as an inhibitor.

Description

technical field [0001] The invention belongs to the technical field of medicine, in particular to a compound with heat shock protein 70 inhibitory activity and application thereof. Background technique [0002] Heat shock protein 70 (Hsp70) is widely distributed in various organisms, and its sequence and structure are highly conserved from lower bacteria to higher mammals. Hsp70 consists of an amino-terminal nucleotide-binding domain, a carboxy-terminal substrate-binding domain (SBD), and a hydrophobic flexible chain of about ten amino acid residues connecting between the nucleotide-binding domain and the substrate-binding domain. Among them, the substrate-binding domain (SBD) can be further divided into β-sheet-rich SBDβ subdomain and α-helix-rich SBDα subdomain. [0003] There are literature reports, (PES) is an inhibitor of Hsp70 and is thought to possibly bind to the SBD of Hsp70. PES can selectively kill tumor cells, but has no toxicity to normal cells at the same c...
