  • Cancer e.g., tumor, neoplasm, metastases
  • K-Ras Kirsten Ras oncogene
  • PDAC pancreatic ductal adenocarcinoma
  • Ras proteins have long been considered to be “undruggable,” due to, in part, high affinity to their substrate Guanosine-5'-triphosphate (GTP) and/or their smooth surfaces without any obvious targeting region.
  • GTP Guanosine-5'-triphosphate
  • Recently, a specific G12C Ras gene mutation has been identified as a druggable target.
  • such therapeutic approach is still limiting, as the G12C mutation in Ras has a low prevalence rate (e.g., about 3% in PDAC) as compared to other known Ras mutations including G12D, G12V, G12S mutations.
