Biological Activity

TH588 a first-in-class nudix hydrolase family inhibitor that potently and selectively engages and inhibits the MTH1 protein in cells. Protein co-crystal structures demonstrate that the inhibitor binds in the active site of MTH1.

MTH1 inhibitor TH588 is highly selective towards MTH1, with no relevant inhibition of other members of the nudix protein family or a panel of 87 enzymes, GPCRs, kinases, ion channels and transporter. TH588 also induces DNA damage and triggers an ATM-p53-mediated death response and DNA repair in U2OS cells. TH588 has been shown to selectively kill a variety of cancer cell lines and with in vivo activity shown for TH588 in SW480 colorectal and MCF7 breast tumour xenografts.

In mice bearing SW480 colorectal or MCF7 breast tumor xenografts, TH588 (30 mg/kg s.c.) reduces tumor growth via MTH1 inhibition. In mice carrying patient with BRAFV600E mutated xenografts, TH588 (30 mg/kg s.c.) also causes a reduced tumor growth rate.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
