This invention belongs to the field of compound technology, specifically a
small molecule compound inhibitor antagonizing GREM1 and its application in the treatment of
colorectal cancer. The specific preparation process of this
small molecule compound inhibitor is as follows: First, the DEL (
DNA-encoded
chemical library)
library is dried under vacuum, then dissolved in a
protein solution containing 5-10 µM human Grem1
protein, and incubated in a DEL screening buffer
system for 30 minutes; after incubation, the Grem1
protein is immobilized using 20 µl of HisPur™ Ni-NTA Magnetic Beads, and incubation continues for 15 minutes, followed by washing with 10 × 100 µl of screening buffer under shaking, and finally removing unbound
library molecules by
vacuum aspiration; the
small molecule inhibitor screened by this application using
DNA-encoded libraries (DEL) has the advantages of small size, strong permeability, tunable
pharmacokinetics, and low cost, and can inhibit the migration and invasion of
colorectal cancer.
