The active metabolites of adefovir and tenofovir (PMEApp and PMPApp) are active against the MMTV RT. They are 25-fold more potent than 3TCppp, suggesting that tenofovir and adefovir may be effective at inhibiting the MMTV-like retroviruses, which may be the etiological agents involved in PBC and breast cancer.
