ORM-15341 is an active main metabolite of ODM-201, which is structurally distinct from any known antiandrogens including the second-generation antiandrogens enzalutamide. ORM-15341 is a potent and full antagonist for human androgen receptor. It was shown, that in VCaP prostate cancer cells containing endogenous AR gene amplification and overexpressing AR, ORM-15341 inhibited cell proliferation more efficiently than enzalutamide or ARN-509.

TAK-779 is a selective antagonist of CCR5 receptor, which was initially developed by Takeda for the treatment of HIV infection. However, the development was terminated due to poor oral bioavailability. Also, TAK-779 demonstrated the ability to protect the brain against focal cerebral ischemia in mice.
