Using a parallel synthesis approach to target a non-conserved region of the PI3K catalytic
domain a pan-PI3K inhibitor 1 was elaborated to provide alpha, delta and gamma isoform
selective Class I PI3K inhibitors 21, 24, 26 and 27. The compounds had good cellular activity
and were selective against protein kinases and other members of the PI3K superfamily
including mTOR and DNA-PK.
