Topoisomerase II inhibitor; daunorubicin analog; anti-leukemic; anthracycline

Temozolomide is an imidazotetrazine alkylating agent. It has anti-tumor activity against a broad spectrum of tumors, such as leukemias, lymphomas and solid tumors. Temozolomide induces G2/M arrest, preventing cells from entering mitosis and, therefore, apoptosis. As a drug resistance-modifying agent it is used for studying drug resistance mechanisms in glioblastoma cell lines.

Applications A highly reactive thiol-specific cross-linking spin-label.

Stability Light and Moisture Sensitive
Applications A cross-linking, biotin-labelled compound.

Applications A water soluble, bulkier analogue of the charged MTS reagent MTSET. Charged MTS reagents have been used successfully with SCAM (substituted cysteine accessibility method) to probe the topology and function of a number of ligand-gated ion channels and transporter proteins.

Applications A bifunctional iron chelating agent that has been employed to couple metal ions to biological molecules, including radiopharmaceutical synthesis and targeted protein hydrolysis. Bifunctional chelating reagents possess both a strong metal-binding moiety and a group that binds to a biological molecule.
