Biological Activity for K34c

K34c is a potent and selective α5β1 integrin inhibitor (IC50 = 3.1 nM). K34c inhibits cell survival and migration, inhibits p53-dependent senescence induced by Temozolomide (Cat. No. 2706) or Ellipticine (Cat. No. 3357) and promotes apoptosis in U87MG cells. K34c also prevents TGFβ-induced infiltration in vivo and reduces cell adhesion on fibronectin.

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.
