How long is Temozolomide stable for when dissolved as recommended, in DMSO at 10 mg/mL and storaged at 2-8C? Also, can the solution only be stored at 2-8C or can it be stored at -20C or -80C for long term storage
1 answer-
Wherever possible, solutions should be prepared fresh and used on the same day. However, should stock solutions need to be prepared in advance, store in aliquots at -20°C for up to 1 month. Allow aliquots to equilibrate to room temperature prior to opening. The long term storage at other temperatures is not determined. However, the published reference below may prove helpful:

Is Temozolomide (Product No. T2577) an active drug or a prodrug?
1 answer-
Temozolomide is considered a prodrug. It is hydrolyzed in vivo to MTIC (monomethyl triazeno imidazole carboxamide). See: Kim, H. et al., High-performance liquid chromatographic analysis and stability of anti-tumor agent temozolomide in human plasma. Journal of Pharmaceutical and Biomedical Analysis, 24(3), 461-468 (2001).
