Temozolomide-d3 is the deuterium labeled Temozolomide. Temozolomide (NSC 362856) is an oral active DNA alkylating agent that crosses the blood-brain barrier. It is also a proautophagic and proapoptotic agent. Temozolomide is effective against tumor cells characterized by low levels of O6-alkylguanine DNA alkyltransferase (OGAT) and a functional mismatch repair system. It has antitumor and antiangiogenic effects.

• Deuterium labeled Temozolomide.
• Oral active DNA alkylating agent.
• Crosses the blood-brain barrier.
• Proautophagic and proapoptotic agent.
• Effective against tumor cells with low levels of OGAT and a functional mismatch repair system.
• Antitumor and antiangiogenic effects.
• Can be used as a tracer.
• Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.

Ketoprofen-d4 (RP-19583-d4) is a deuterium-labeled derivative of Ketoprofen, a non-steroidal anti-inflammatory agent (NSAID). This compound acts as a potent inhibitor of cyclooxygenase (COX) enzymes, with reported IC50 values of 2 nM for COX-1 and 26 nM for COX-2 in human blood monocytes. Deuteration can influence the pharmacokinetic and metabolic profiles of drugs. Ketoprofen-d4 is suitable for use as a tracer in research applications and as an internal standard for quantitative analysis.

• Potent inhibitor of cyclooxygenase enzymes
• Suitable for use as a tracer in research applications
• Ideal as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS
• Stable heavy isotope
• Highly soluble in DMSO
