Biochem/physiol Actions

Potent mevalonate (MVA) pathway farnesyl diphosphate synthase (FPPS) inhibitor that stimulates immune responses in vivo.


TH-Z93 is a potent farnesyl diphosphate synthase (FPPS) inhibitor (IC50 = 90 nM) that stimulates immune responses by blocking the mevalonate (MVA) pathway-mediated post-translational protein geranylgeranylation. When co-administered with antigen in mice in vivo, TH-Z93 triggers strong adjuvant responses, increasing OVA-specific antibody titres (in mice immunized with 100 μg OVA + 100 μg TH-Z93) and protects against death caused by live influenza virus PR8 challenge (in mice immunized with 5 μg PR8 HA1 subunit containing TH-Z93). TH-Z93 adjuvant efficacy is blocked by GGPP and synergized with HMG-CoA inhibitor simvastatin.

Small cell lung cancer (SCLC) lacks effective treatments to overcome chemoresistance. Here we established multiple human chemoresistant xenograft models through long-term intermittent chemotherapy, mimicking clinically relevant therapeutic settings. We show that chemoresistant SCLC undergoes metabolic reprogramming relying on the mevalonate

Cell, 175(4), 1059-1073 (2018-10-03)
Motivated by the clinical observation that interruption of the mevalonate pathway stimulates immune responses, we hypothesized that this pathway may function as a druggable target for vaccine adjuvant discovery. We found that lipophilic statin drugs and rationally designed bisphosphonates that
