LYP-IN-1 is a potent and highly selective inhibitor of lymphoid-specific tyrosine phosphatase (LYP), with a Ki value of 110 nM and an IC50 of 0.259 μM. LYP-IN-1 exhibits additional selectivity against a broad range of PTPs, including SHP1 (IC50 = 5 μM) and SHP2 (IC50 = 2.5 μM). LYP-IN-1 demonstrates strong efficacy in both T cells and mast cells, making it a valuable compound for research into autoimmune disorders and immune signaling pathways.

Lipid PPz-2R1 is an ionizable cationic lipid employed in crafting lipid nanoparticles (LNPs) for mRNA delivery both in vitro and in vivo. LNPs with lipid PPz-2R1, encapsulating an mRNA reporter, target the lungs preferentially over the heart, liver, spleen, and kidneys in mice. Additionally, these LNPs, when encapsulating mRNA encoding phosphatase and tensin homolog (PTEN), enhance PTEN protein levels in PTEN-deficient Lewis lung carcinoma (LLC) cells. In an orthotopic murine LLC model, these Lipid PPz-2R1-containing LNPs, carrying PTEN mRNA, reduce tumor growth either when administered alone or alongside an antibody against programmed cell death protein 1 (PD-1).
