• Jul 28, 2014 · The molecule, SML-8-73-1 (SML), interferes with the KRAS gene, or Kirsten rat sarcoma viral oncogene homolog. The gene produces proteins called K-Ras that influence when cells divide.
  • Small Molecule Pan-RAS Inhibitors Oncogenic mutations in the RAS family of genes (KRAS, HRAS, and NRAS) are present in approximately 30% of cancer. Figure 1 below illustrates the proportion of RAS mutations found in common tumor types. RAS plays a pivotal role in signal transduction pathways leading to tumor cell proliferation and survival.
  • It was known that RAS inhibitors suppressed the progres-sion of overt diabetic nephropathy, but it remained unclear whether RAS inhibitors would bring out some favorable effects on renal function even before the onset of diabetic nephropathy. In this study, we showed that RAS inhibitor O (95% CI), p F T HA1 <7.0% ≥7.0% BP <130/80 ≥130/80 0 ...
  • 9 hours ago · Renin-angiotensin system inhibitors (RAS inhibitors) include class of drugs like Angiotensin Converting Enzyme (ACE) inhibitors (ending in 'pril') and Angiotensin Receptor Blockers (ARBs ending in ...
  • Abstract Introduction: KRAS is one of the most important oncology drug targets, playing a pivotal role in the initiation and progression of many human tumors. It has long been held undruggable due...
  • Mirati has announced initial data for its first-in-class KRAS G12D inhibitor, known as MRTX1133. The experimental drug appears to have a long half-life and little potential for drug interactions or off-target activity. It was found to shrink tumors, including pancreatic and colorectal cancer, in preclinical studies.
  • Aug 27, 2019 · Machavert will advance the new class of cancer therapeutics, RAL GTPase inhibitors, targeting KRAS mutant cancers. The RAL inhibitors were discovered at the University of Colorado School of Medicine (CU) and relevant research was published in Nature in 2014. Machavert has been developing the RAL inhibitors since it entered into an exclusive ...

Dec 29, 2020 · KRAS G12C Inhibitors . Sotorasib . Activity focused on KRAS G12C took off recently following the discovery of a shallow switch II pocket in the mutant KRAS G12C protein, which enabled the development of covalent inhibitors of KRAS G12C. 1,4. Sotorasib (AMG 510) was one of the first such molecules to enter human clinical trials.
With the discovery of a unique surface groove in the KRAS G12C protein, Amgen developed and advanced the first investigational KRAS G12C inhibitor into the clinic and is exploring the potential of KRAS G12C inhibition across multiple tumor types for patients who remain in dire need of treatment options. 1, 10

Sotorasib (formerly AMG 510) targets a specific mutation, known as KRAS G12C, found in about 14% of non-small-cell lung cancer (NSCLC) and a smaller proportion of other solid tumors. In the Phase I/II CodeBreaK 100 study, sotorasib led to tumor shrinkage in 32% of patients with advanced NSCLC.
Nov 07, 2012 · However, in tumors and normal cells with wild-type RAF, these inhibitors stimulate ERK signaling in a RAS-dependent manner. 8,12-16 This paradoxical activation is thought to explain why this class ...

Direct factor Xa inhibitors ('xabans') are a class of anticoagulant drugs which act directly upon factor X in the coagulation cascade, without using antithrombin as a mediator. [1] Antistasin , the first discovered naturally occurring direct Xa inhibitor
Two features of KRAS confound its tractability as a drug target: (1) KRAS binds to GDP and GTP with picomolar affinity, severely hindering efforts to develop nucleotide-competitive inhibitors, and (2) the KRAS protein lacks other deep surface hydrophobic pockets, thwarting efforts to identify high-affinity allosteric inhibitors.
