Design and Synthesis of New Templates Derived from Pyrrolopyrimidine as Selective Multidrug-Resistance-Associated Protein Inhibitors in Multidrug Resistance
摘要:
In our continued effort to identify selective MRP1 modulators, we have developed two novel templates, 3 and 4, through rational drug design by identifying the key pharmacophore interaction at the 7-position of the pyrrolopyrimidine template 1. Further synthesis and SAR work on these novel templates gave a number of potent MRP1 modulators with great selectivity against Pgp. Additional studies to reduce the CYP3A4 inhibition are also reported. Several compounds of these classes were subjected to in vivo xenograft studies and in vivo efficacies were demonstrated.

Most of the evaluated derivatives showed a moderate to excellent anti‐proliferative activity towards the selected cell lines. Of these, compounds 4h, 4k, 10, 12a, and 12b showed both potent anticancer activity (IC50<10 μM) and lower cytotoxic effect (IC50 > 58 μM) on non‐tumorigenic cells (MCF‐10A and NCM460), suggesting their promising potential to be lead molecules for future antitumor drug discovery

A simple strategy for the synthesis of 2-oxo-1,2-dihydropyridine-3-carbonitrile derivatives (2-oxonicotinonitrile, 3-cyanopyridone) in good yields by substituting the halogen atom with an oxime under mild conditions was developed. The proposed approach makes it possible to avoid the problems associated with the hydrolysis of easily modified groups, since the reaction is carried out in the absence of
