pi-3065 is a small molecule and selective inhibitor of p110δkinase with an ki value of 1.5nm and ic50 value of 5nm [1].pi-3065 has been reported to selectively inhibit p110δkinase with ki values of 15nm, 110nm, 130nm and 940nm, ic50 values of 5nm, 91nm, 600nm and >10000nm for p110δ, p110α, p110β and p110γ, respectively. in addition, pi-3065 has been revealed to inhibit 4t1 tumour growth and metastasis. pi-3065 has also noted to prolong survival and reduce the incidence of macroscopic metastases and other disease-associated pathologies [1].
