Paclitaxel-d5 contains five deuterium atoms. It is intended for use as an internal standard for the quantification of paclitaxel using GC- or LC-MS. Paclitaxel is cytotoxic against a variety of cancer cell lines with IC50 values ranging from 2.5-7.5 nM.1 It disrupts multipolar spindle formation, inducing cell cycle arrest in various human cell cancer lines (IC50s = 6.7-18.5 nM) at both prophase and G1.2 It also initiates apoptosis of cancer cells through multiple mechanisms involving p53-dependent and -independent pathways, Bcl-2 family members, cyclin-dependent kinases, and c-Jun N-terminal kinases/stress-activated protein kinases.3
