Abstract

PI3K is a promising therapeutic target for cancer. With PI-103 as the lead compound, we designed and synthesized 4-(2-arylpyrido[3',2':3,4]pyrrolo[1,2-f][1,2,4]triazin-4-yl)morpholine derivatives. 9, 10a, 10d, 10e had the IC(50) against PI3Kα comparable with PI-103. All of the compounds showed selectivity over 15 tested protein kinases and anti-proliferative activity at micromolar concentration against several cancer cell lines.
