Discovery of novel dual inhibitors of receptor tyrosine kinases EGFR and PDGFR-β related to anticancer drug resistance
摘要:
With ongoing resistance problems against the marketed EGFR inhibitors having a quinazoline core scaffold there is a need for the development of novel inhibitors having a modified scaffold and, thus, expected lower EGFR resistance problems. An additional problem concerning EGFR inhibitor resistance is an observed heterodimerization of EGFR with PDGFR-beta that neutralises the sole inhibitor activity towards EGFR. We developed novel pyrimido[4,5-b] indoles with varied substitution patterns at the 4-anilino residue to evaluate their EGFR and PDGFR-beta inhibiting properties. We identified dual inhibitors of both EGFR and PDGFR-beta in the nanomolar range which have been initially screened in cancer cell lines to prove a benefit of both EGFR and PDGFR-beta inhibition.

Peptidomimetics of cyclic peptides, and compositions comprising such peptidomimetics are provided. The peptidomimetics have a three-dimensional structure that is substantially similar to a three-dimensional structure of a cyclic peptide that comprises a cadherin cell adhesion recognition sequence HAV. Methods for using such peptidomimetics for modulating cadherin-mediated cell adhesion in a variety of contexts are also provided.
