Using a rational design strategy for isoform-selective inhibition of PI3Kα, two series of novel 2,3,4,5-tetra-substituted thiophene derivatives containing either diaryl urea or N-Acylarylhydrazone scaffold were designed and synthesized. The most promising compound 12k was demonstrated to bear nanomolar PI3Kα inhibitory potency with 12, 28, 30, 196-fold selectivity against isoforms β, γ, δ and mTOR. Besides, it also showed good developability profiles in cell-based proliferation against a panel of human tumor cells as well as ADME assays
