Podophyllotoxin-d6 (Synonyms: PPT-d6)

Podophyllotoxin-d₆ is intended for use as an internal standard for the quantification of podophyllotoxin and picropodophyllotoxin by GC- or LC-MS. Podophyllotoxin is a lignan that has been found in Podophyllum and has diverse biological activities.^1,2,3,4,5 It inhibits polymerization of isolated chicken brain tubulin (IC₅₀ = 0.6 µM) and induces mitotic arrest at the G₂/M phase in CCRF CEM lymphoblastic leukemia cells when used at concentrations ranging from 0.01 to 5 µg/ml.^2,3 Podophyllotoxin (5 µM) is protective against herpes simplex virus 1 (HSV-1) infection in Vero cells.⁴ It inhibits the proliferation of several diffuse large B cell lymphoma (DLBCL) cell lines (IC₅₀s = 0.0098-0.017 µM).⁵ Podophyllotoxin is a starting material in the semisynthesis of the anticancer compounds etoposide and teniposide .⁶ Formulations containing podophyllotoxin have been used in the treatment of external genital warts.
