(S)-Verapamil D7 HCl ((S)-(-)-Verapamil D7 HCl) is a deuterated form of (S)-Verapamil HCl. (S)-Verapamil HCl (S(-)-Verapamil HCl) inhibits leukotriene C4 (LTC4) and calcein transport by MRP1. (S)-Verapamil HCl leads to the death of highly potentially resistant tumor cells. References: [1]. Perrotton T, et al.
