Lomeguatrib Chemical Properties,Uses,Production
Description
Lomeguatrib (192441-08-0) is a potent (IC50?= 9 nM) inhibitor of O6-Methylguanine-DNA Methyltransferase (MGMT), an important DNA repair protein.1?It is currently being investigated in cancers that have acquired resistant to the chemotherapeutic temozolomide2-5, as well as other chemotherapeutics6,7.
Uses
O6-Methylguanine-DNA methyltransferase (MGMT) is a DNA repair protein which removes an alkyl group from the O6 position on guanine in an autoinactivating reaction. Although important in normal DNA repair, this reaction confers resistance to treatments that use O6-alkylating agents to produce cytotoxicity, e.g., in cancer. Lomeguatrib is a modified quanine base which acts as a pseudosubstrate inactivator of MGMT (IC50 = ~3 nM). A non-toxic compound, lomeguatrib completely inactivates MGMT in human prostate and colorectal tumors when given as a single 120 mg oral dose and in primary central nervous system cancers at 160 mg.
Uses
Lomeguatrib is an inhibitor of O6-methylguanine-DNA methyltransferase (MGMT). Lomeguatrib attenuates MGMT activity in vitro and in vivo. Lomeguatrib enhances the antitumor activity of temozolomide in both human melanoma and MCF-7 xenografts.
