Description: AVN-944 (VX-944) is an orally available, synthetic small molecule with potential antineoplastic activity. AVN944 inhibits inosine monosphosphate dehydrogenase (IMPDH), an enzyme involved in the de novo synthesis of guanosine triphosphate (GTP), a purine molecule required for DNA and RNA synthesis. Inhibition of IMPDH deprives cancer cells of GTP, resulting in disruption of DNA and RNA synthesis, inhibition of cell proliferation, and the induction of apoptosis. AVN944 appears to have a selective effect on cancer cells in that deprivation of GTP in normal cells results in a temporary slowing of cell growth only. IMPDH is overexpressed in some cancer cells, particularly in hematological malignancies.

|Biological target:||AVN-944(VX-944) is a selective, noncompetitive inhibitor of the enzyme directed against human IMPDH with Ki of 6-10 nM for IMPDH1/IMPDH2.|
|In vitro activity:||The effect of VX-944 on growth of MM cell lines was determined using the MTT assay. VX-944 significantly inhibited the growth of RPMI8226, MM.1S, and U266 cells in a dose-dependent fashion, with 50% inhibition (IC50) values at 48 h of 450, 450, and 600 nM, respectively. VX-944 also inhibited growth of drug-resistant cell lines, including doxorubicin (Dox)-resistant RPMI8226-Dox40, melphalan (Mel) resistant RPMI8226-LR5, and Dex (dexamethasone) resistant MM.1R cells, with IC50 values similar to the parental drug-sensitive cell lines (Figure 1a).
