Provided herein are hemiasterlin derivatives, conjugates thereof, compositions comprising the derivatives or conjugates thereof, methods of producing the derivatives and conjugates thereof, and methods of using the derivatives, conjugates, and compositions for the treatment of cell proliferation. The derivatives, conjugates, and compositions are useful in methods of treatment and prevention of cell proliferation and cancer, methods of detection of cell proliferation and cancer, and methods of diagnosis of cell proliferation and cancer. In an embodiment, the hemiasterlin derivatives are according to Formula 1000: ##STR00001##
or a pharmaceutically acceptable salt, solvate, or tautomer thereof, wherein Ar, L, W.sup.1, W.sup.4, W.sup.5, SG, and R are as described herein.

Disclosed are methods, systems, components, and compositions for cell-free synthesis of glycosylated proteins. The glycosylated proteins may be utilized in vaccines, including anti-bacterial vaccines. The glycosylated proteins may include a bacterial polysaccharide conjugated to a carrier, which may be utilized to generate an immune response in an immunized host against the polysaccharide conjugated to the carrier. The glycosylated proteins may be synthesized in cell-free glycoprotein synthesis (CFGpS) systems using prokaryote cell lysates that are enriched in components for glycoprotein synthesis such as oligosaccharyltransferases (OSTs) and lipid-linked oligosaccharides (LLOs) including OSTs and LLOs associated with synthesis of bacterial O antigens.

The present invention relates to recombinant polypeptide therapeutics having an engineered O-linked amino acid (AA) glycosylation sequence (motif), which is covalently linked to O-glycan(s) (tag). Recombinant O-glycosylated polypeptides may be produced in mammalian cells to present natural or un-natural O-glycan structures through metabolic labelling.

Provided herein are glycosylated peptide amphiphiles (GPAs), supramolecular glyconanostructures assembled therefrom, and methods of use thereof. In particular, provided herein are glycosaminoglycan (GAG) mimetic peptide amphiphiles (PAs) and supramolecular GAG mimetic nanostructures assembled therefrom that mimic the biological activities of GAGs, such as heparin, heparan sulfate, hyaluronic acid etc.

Disclosed herein are novel compounds and uses thereof. The present compounds are useful in suppressing the growth of various bacteria, including gram-positive and gram-negative bacteria. Accordingly, these compounds may be used to manufacture a medicament or pharmaceutic composition for treating disease and/or disorders associated with bacterial infection, especially antibiotic-resistant bacterial infection. Al so disclosed herein are methods for treating infectious diseases by use of the present compounds, medicament or pharmaceutical composition.

The present invention provides oligopeptides, in particular, Ang-(1-7) derivatives, and methods for using and producing the same. In one particular embodiment, oligopeptides of the invention have higher blood-brain barrier penetration and/or in vivo half-life compared to the native Ang-(1-7), thereby allowing oligopeptides of the invention to be used in a wide variety of clinical applications including in treatment of cognitive dysfunction and/of impairment.

The disclosed embodiments concern methods, devices, and systems for identifying candidate biomarkers useful for the diagnosis, prognosis, monitoring and screening and/or as targets for the treatment of diseases and conditions in subjects, in particular autoimmune and infectious diseases. The identification of candidate biomarkers is predicated on identifying discriminating peptides present on a peptide array, which can distinguish samples from different subjects having different health conditions by the binding patterns of antibodies present in the samples.

The present disclosure relates to novel antibacterial cell-penetrating peptides and derivatives, and methods to make and use the novel antibacterial cell-penetrating peptides and derivatives. The novel antibacterial cell-penetrating peptides of the present invention with shorter linker between a pyrrolidine ring and a guanidine group provide unexpectedly higher potency against a broader scope of bacterial.

The peptides of the invention are of formula (I) or (IV). The peptides of the invention are useful in the treatment of cancer. ##STR00001##

The present invention relates to peptides, in particular cell penetrating peptides, of 40 amino acid residues or less comprising at least one directly glycosylated amino residue and one or more arginine rich arm domains, and to conjugates of such cell penetrating peptides with a therapeutic molecule. The present invention further relates to the use of the peptides or conjugates in methods of treatment or as a medicament, especially in the treatment of genetic disorders of the central nervous system. page.
