Using pyridino[2,3-D]pyrimidine as the core, total 13 pyridino[2,3-D]pyrimidine derivatives with different alkyl substituents at C2 site have been designed and synthesized to search for novel PI3Kα/mTOR dual inhibitors. Most of the target compounds showed potent mTOR inhibition activity with IC50 values ranging from single to double digit nanomole. Five target compounds exhibited pronounced PI3Kα inhibition activity. In vitro cellular assay indicated that most of the target compounds showed excellent antiproliferative activity, especially 3j whose potency against SKOV3 was 8-fold higher than the positive control AZD8055. In vitro metabolic stability study found that 3j had a comparable stability to that of AZD8055. More importantly, 3j showed better antitumor activity and pharmacokinetic properties in vivo as compared with AZD8055.
