Combination of 4-anilinoquinazoline and rhodanine as novel epidermal growth factor receptor tyrosine kinase inhibitors
摘要:
A type of novel rhodanine-based 4-anilinoquinazoline, which designed the combination between quinazoline as the backbone and various substituted biological rhodanine groups as the side chain, have been synthesized, and their antiproliferative activities were also evaluated firstly. These compounds displayed good antiproliferative activity and EGFR-TK inhibitory activity. Among them, compound 8d showed good inhibitory activity (IC50 = 2.7 mu M for Hep G2, IC50 = 3.1 mu M for A549) and molecular docking of 8d into EGFR TK active site was also performed, this inhibitor well fitting the active site might well explain its excellent inhibitory activity.

Six focused rhodanine-based libraries, 60 compounds in total, were synthesized and evaluated as potential dynamin I GTPase inhibitors. Twenty-six were more potent than the lead compound with 13 returning IC50 values <10 mu M, making the Rhodadyn series among the most active dynamin inhibitors reported. Two analogues were highly effective at blocking receptor-mediated endocytosis: C10 and D10 with IC50(RmE) = 7.0 +/- 2.2 and 5.9 +/- 1.0 mu M, respectively. These compounds are equipotent with the best reported in-cell dynamin inhibitors.
