CMX157 was observed to have highly potent antiviral activity against XMRV in vitro, with an EC50 approximately 20-fold more potent than the anti-retroviral drug azidothymidine (AZT) and 800-fold more potent than tenofovir.

Azidothymidine, the first drug that was approved in the fight against AIDS in the 1980s, is still a main component in the medication mix commonly prescribed to HIV patients today.
