Bacterial Proteasome

Octaarginine acetate is a cell-penetrating peptide and proteasome inhibitor. Octaarginine acetate exhibits mixed-type inhibition against 20S proteasome chymotrypsin-like, caspase-like, and trypsin-like activities, and inhibits 26S proteasome activity with decreased efficiency. Octaarginine acetate induces ubiquitin-conjugated protein accumulation, mediates HSPG-dependent cellular internalization via macropinocytosis, enhances liposomal cargo uptake and gene delivery. Octaarginine acetate can be used for the research of cervix carcinoma, collagen antibody-induced arthritis, and bacterial infections .

Research Areas:  

Inflammation/Immunology

PTD-DBM is a CXXC5-Dvl protein-protein interaction inhibitor and also a Wnt/β-catenin pathway activator. PTD-DBM interferes with the Dvl-binding function of CXXC5, disrupts the negative feedback regulation of the Wnt/β-catenin pathway, induces β-catenin expression and nuclear translocation, and increases the production of type I collagen, α-smooth muscle actin and endothelin-1. PTD-DBM is applicable to studies related to androgenetic alopecia and skin wound healing .

Low molecular weight protamine (LMWP;TDSP5) is a truncated arginine-rich protamine peptide, as well as a heparin/low-molecular-weight heparin antidote and a cell-penetrating delivery carrier. Low molecular weight protamine neutralizes heparin-induced anticoagulant activities, including aPTT, anti-Xa and anti-IIa activities, and also neutralizes anti-Xa activity of commercially available low-molecular-weight heparin preparations. Low molecular weight protamine translocates across mammalian cell membranes, delivers conjugated impermeable molecules across tumor tissues, enhances skin permeability of conjugated epidermal growth factor, and accelerates wound healing when conjugated with epidermal growth factor. Low molecular weight protamine retains the in vitro cell proliferation activity of conjugated EGF, and also enables site-specific conjugation with peptides or proteins via genetic recombination. Low molecular weight protamine can be used in studies related to colon adenocarcinoma, skin wounds and diabetic skin wounds .

Cys(Npys)-(Arg)9 acetate is a synthetic cationic cell-penetrating peptide with a reversible thiol-reactive nitropyridyl (Npys) group. Cys(Npys)-(Arg)9 acetate efficiently mediates the internalization and delivery of various "cargo" such as proteins and antibodies by forming reversible disulfide bonds with surface-exposed cysteine residues. Cys(Npys)-(Arg)9 acetate endows TALEN proteins with cell-penetrating activity, enabling gene knockout in mammalian cells and protein transduction in wheat microspores. Cys(Npys)-(Arg)9 acetate can be conjugated with antibodies to form cationized IgG for enhancing endosomal escape of oligonucleotides, or form siRNA delivery complexes. When the molar ratio of Cys(Npys)-(Arg)9 acetate to loaded molecules is higher than 1:1, it exerts certain cytotoxic effects on cells. Cys(Npys)-(Arg)9 acetate can be used in studies related to oral squamous cell carcinoma and HIV infection .

HXR9 is a cell-permeable peptide and a competitive antagonist of HOX/PBX interaction. HXR9 antagonizes the interaction between HOX and a second transcrip-tion factor (PBX), which binds to HOX proteins in paralogue groups1 to 8. HXR9 selectively decreases cell proliferation and promotes apoptosis in cells with a high level of expression of the HOXA/PBX3 genes, such as MLL-rearranged leukemic cells .
