    • Though it is possible that the cellular activity of non-pyrophosphates such as compound 3, N3P-TT, is a result of their direct interaction with TK, we believe it is much more likely that they are first converted by TPPK inside the cell into their pyrophosphate forms. The pyrophosphate binding to TK is greater by several orders of magnitude than the corresponding non-pyrophosphate analogs (Table 1).

    • note
    • Prior to performing the TPPK/Apo-TK assay, each compound was evaluated for its ability to be pyrophosphorylated by TPPK using thiamine as a control substrate. The extent of substrate pyrophosphorylation relative to thiamine pyrophosphorylation was determined prior to competition with TPP in inhibiting TK activity according to methods described in WO2005/095391.
