||||||||||CBT-103 / Cellective BioTherap Journal, BRCA Biomarker: Structure guided synthesis and evaluation of small molecule inhibitors targeting protein-protein interactions of BRCA1 tBRCT domain. (Pubmed Central) - Sep 24, 2020 Two analogues, CCBT2088 and CCBT2103 were effective in abrogating BRCA1 foci formation and inhibiting G2 arrest induced by irradiation of cells. Collectively, our findings reveal structural features underlying the activity of a novel inhibitor of phosphopeptide recognition by the BRCA1 tBRCT domain, providing fresh insights to guide the development of inhibitors that target protein-protein interactions.
