Biological Activity for E 7820

E 7820 is a α2 integrin inhibitor. Inhibits angiogenesis in vitro (IC50 = 0.11 - 0.25 μM). Also inhibits growth of human colorectal cancer cell lines. Enhances efficacy of erlotinib in a non-small-cell lung cancer xenograft model. Also acts as a molecular glue to induce proteosomal degradation of mRNA splicing factor RBM39.

Enabling Research By Provision of Chemical Tools Poster

The Tocris chemistry team has considerable chemistry knowledge and skill which it has recently been applying to the generation of new chemical probes from known tools and compounds to help answer biological questions. This poster presents some of the work carried out by Tocris scientists and focuses on two areas: the generation of libraries of chemical building blocks to support Degrader (PROTAC) research and the development of a fluorescent probe to study integrin biology.
