Off-patent Drug Library

2,778 compounds

Drug repurposing (also called drug repositioning, reprofiling, or re‑tasking) offers various advantages over developing an entirely new drug for a given indication, for example, lower risk of failure, less investment, and shorter development timelines. But drug repositioning projects are also subject to several risks, including regulatory and intellectual property issues. So the off-patent drugs are optimal for repositioning because of their immediate availability for clinical studies, with high feasibility and relatively low risk.

MCE carefully prepared a unique collection of 2,778 off-patent drugs, which is a good choice for drug repurposing.

WKYMVM-NH2	Formyl Peptide Receptor (FPR)	Inflammation/Immunology
WKYMVM-NH2 is a hexapeptide that activates neutrophils and myeloid cells via the FPRL1 and FPRL2 receptors. It exhibits EC₅₀ values of 2 nM and 80 nM in HL-60-FPRL1 and HL-60-FPRL2 cells, respectively. In HL-60 cells stably expressing FPRL2, WKYMVM-NH₂ induces chemotaxis, with optimal migration observed at concentrations ranging from 10 to 50 nM. It also stimulates superoxide production in neutrophils, with an EC₅₀ of 75 nM. WKYMVM-NH₂ is a useful tool for research in the field of inflammatory diseases .

MRTX1133 20+ Cited Publications		Alkynes
MRTX1133 is a noncovalent, potent, and selective alkyne-based KRAS G12D inhibitor. MRTX1133 optimally fills the switch II pocket and extends three substituents to favorably interact with the protein, resulting in an estimated K_D against KRAS G12D of 0.2 pM. MRTX1133 prevents SOS1-catalyzed nucleotide exchange and/or formation of the KRAS G12D/GTP/RAF1 complex, thereby inhibiting mutant KRAS-dependent signal transduction. MRTX1133 selectively inhibits KRAS G12D mutant, but not KRAS wild-type, tumor cells. MRTX1133 has single digit nanomolar activity in cellular assays and marked in vivo efficacy in tumor models harboring KRAS G12D mutations .
