ZD4054 is a specific antagonist of the endothelin A receptor.
The autocrine endothelin (ET)-1/endothelin A receptor (ETAR) pathway is an important regulator of several processes involved in ovarian cancer progression.
In vitro: In the human ovarian cancer ETAR positive cell lines, ZD4054 effectively inhibited the basal and ET-1-induced cell proliferation, with the inhibition of AKT and p42/44MAPK phosphorylation, and increased apoptosis, through the inhibition of bcl-2 and activation of caspase-3 and poly(ADP-ribose) polymerase proteins. [1].
In vivo: In HEY ovarian cancer xenografts, ZD4054 inhibited tumor growth to the same degree as paclitaxel. Moreover, ZD4054-dependent tumor growth inhibition was associated with a reduction in proliferation index, MMP-2 expression, and microvessel microvessel density [2].
Clinical trial: The PK and safety profiles of ZD4054 determined in this Chinese patient population are similar to those previously reported. Findings suggest no clinically relevant inter-ethnic differences in ZD4054 disposition between the patient populations analyzed [3].
