The micromolar apparent Km value of tecadenoson for transport by native hENT1 in cultured cells suggests that hENT1 will not be saturated at clinically relevant ( i . e . , nanomolar ) concentrations of tecadenoson , and that hENT1 - mediated passage across the BBB may contribute to the adverse CNS effects observed in clinical trials .
