Pictilisib is an oral potent inhibitor of class I PI3K with nanomolar activities against p110alpha, p110beta, p110delta, and p110gamma. The drug was developed for the treatment of solid tumors and reached phase II in patients with breast cancer and lung carcinoma, however its development was terminated.

CNS Activity

Curator's Comment:: Experiments on mice revealed that pictilisib transport to brain is very limited.
