SVC112 is a translation elongation inhibitor that prevents the cyclic dissociation of EF2 from the ribosome, thereby inhibiting the elongation step of translation. SVC112 shows activity in growth inhibition among cancer cell lines of various origins (acute myeloid leukemia (AML), multiple myeloma (Myeloma), colorectal cancer (CRC), and head and neck squamous cell carcinoma (HNSCC)). SVC112 preferentially impedes ribosomal processing of mRNAs, and decreaseds CSC-related proteins including Myc and Sox2. SVC112 induces apoptosis in hematologic cancer cell lines, while phosphorylation of c-Myc correlates with sensitivity to SVC112 in colorectal cancer cell lines. SVC112 inactivates HNSCC stem cells in vitro and prevents the regrowth of HNSCC tumor xenografts in mice. SVC112 can be used for the study of HNSCC.
