Two highly deuterium-labeled compounds, (R)-K-13675-d11 and (R)-K-13675-d7, were prepared for use as internalstandards for low-level quantification of plasma drugs by LC/MS/MS. We successfully demonstrated their utility in pharmacokinetic studies for sensitive and precise drug quantification.
制备了两种高度氘标记的化合物(R)-K-13675- d 11和(R)-K-13675- d 7,用作通过LC / MS / MS低定量定量血浆药物的内标。我们成功地证明了它们在药代动力学研究中用于敏感和精确的药物定量的效用。
