Abstract
Objective: 6-Mercaptopurine (6-MP) is a cancer chemotherapeutic agent. Metabolic pathway by
thiopurine S-methyltransferase (TPMT) to become 6-methylmercaptopurine (6-MMP).Bio-sampling is
required to obtainbiological sample, using two technique; invasive (venipuncture) and minimum
invasive(dried blood spot). This study aims to obtain an optimization and validation analysis 6-MP and
6-MMP in vitro study with bio-sampling venipuncture and dried blood spot (DBS). Method: Plasma from
venipuncture method extraction was done using dichloromethane. Separation was performed using
Waters HPLC, C18 SunfireTM column (5μm, 250 x 4.6 mm), with gradient elution, flow rate 1 mL/min
and detected at UV-PDA wavelength of 303 nm. Bio-sampling dried blood spot with DBS CAMAG®
paper diameter of 8 mm and extracted with acetonitrile-methanol (1:3). Separation was performed with
Waters LC-MS/MS UPLC C18 column (1.7 μm, 2.1 x 100 mm) with gradient elution, flow rate 0.2
mL/min. 5-fluorouracil (5-FU) was used as internal standard.Result: The method venipuncture was
linear at concentration range of 2-200 ng/mL for 6-MP and 20-2000 ng/mL for 6-MMP. The method dried
blood spot using Waters Xevo TQD for mass detection with positive electrospray ionization (ESI) for 6-
MP, 6-MMP and negative ESI for 5-FU in Multiple Reaction Monitoring mode. Linear with the range 26-
1000 ng/mL for 6-MP and 13-500 ng/mL for 6-MMP.Conclusion: The developed method is valid for 6-MP
and 6-MMP simultaneously in vitro from venipuncture using HPLC and from dried blood spot using LCMS/MS
and showed good selectivity, linearity, accuracy and precision, matrix effect and stability.
