Biological Activity
azd5363 is a novel, potent phosphoinositide 3-kinase (pi3k)/akt pathway inhibitor with ic50 value of ~200nm. [1]azd5363 is proved to inhibit castrate resistant prostate cancer (crpc) progression. clusterin (clu) and autophagy will be induced which may work as cytoprotective responses which can affect the downstream pi3k/akt signaling. [2] azd5363 inhibits the growth of a lot of human tumor cells in a dose dependent manner. the mode of action could be monotherapy as well as in combination with her2 inhibitors in breast cancer models. [3] it is suggested to induce cell apoptosis by measuring the expression of parp cleavage, the activity of caspase 3, et al. [1]most importantly, azd5363 can target the pi3k/akt-pathway in vivo significantly, thus reducing the serum psa-levels and tumor volume, finally, it could postpone the progression to crpc.[1]
