Discovery of novel 20S proteasome inhibitors by rational topology-based scaffold hopping of bortezomib.
Bioorganic & medicinal chemistry letters(2018)
Abstract
A series of structurally novel proteasome inhibitors 1-12 have been developed based rational topology-based scaffold hopping of bortezomib. Among these novel proteasome inhibitors, compound 10 represents an important advance due to the comparable proteasome-inhibitory activity (IC50 = 9.7 nM) to bortezomib (IC50 = 8.3 nM), the remarkably higher BEI and SEI values and the effectiveness in metabolic stability. Therefore, compound 10 provides an excellent lead suitable for further optimization.
