In the recent years, PI3Kdelta has emerged as a promising target for the treatment of B- and T-cell mediated inflammatory diseases. We present a cellular assay activity analysis for our previously reported 4,6-diaryl quinazoline PI3Kdelta inhibitor series that suggests an optimal logP range between 2 and 3. We discovered novel analogues in this lipophilicity space that feature a chiral pyrrolidineoxy-group as a replacement for the position-4 aromatic ring of 4,6-diaryl quinazolines. These Fsp3enriched derivatives retain potency and selectivity towards PI3Kdelta. Compared to 4,6-diaryl quinazolines, their permeability profile is improved and molecular weight as well as PSA are reduced. These modifications offer additional possibilities for derivative generation in a favorable physicochemical property space and thus increase the chances to identify a clinical candidate.
