Use of a variable fragment (VHH antibody) of a camelid single-chain antibody for the preparation of a peptide vector for delivering a substance of interest across the blood-brain barrier or into a cell.

This invention describes a method of conjugating a cell binding agent such as an antibody with an effector group (e.g., a cytotoxic agent) or a reporter group (e.g., a radionuclide), whereby the reporter or effector group is first reacted with a bifunctional linker and the mixture is then used without purification for the conjugation reaction with the cell binding agent. The method described in this invention is advantageous for preparation of stably-linked conjugates of cell binding agents, such as antibodies with effector or reporter groups. This conjugation method provides in high yields conjugates of high purity and homogeneity that are without inter-chain cross-linking and inactivated linker residues

This invention relates to composition and methods using lipid formulated siRNA targeted to a PCSK9 gene.

Antigen binding proteins that bind to human IL-23 protein are provided. Nucleic acids encoding the antigen binding protein, vectors, and cells encoding the same as well as use of IL-23 antigen binding proteins for diagnostic and therapeutic purposes are also provided.

Auristatin peptides, including MeVal-Val-Dil-Dap-Norephedrine (MMAE) and MeVal-Val-Dil-Dap-Phe (MMAF), were prepared and attached to Ligands through various linkers, including maleimidocaproyl-val-cit-PAB. The resulting ligand drug conjugates were active in vitro and in vivo.

The present invention relates to novel peptides, compositions and methods for the prevention and/or treatment of pathological conditions and diseases associated with NADPH oxidase 1 (Nox1) activity, and/or increased reactive oxygen species (ROS) production. The novel peptides are thus particularly useful for treating and/or preventing cancer, atherosclerosis, angiogenesis, and aging.

The present invention is directed toward the delivery of a toxic protein to pathogenic cells, particularly cancer cells. In preferred embodiments, the toxic protein is a ribonuclease that has been modified to make it toxic to target cells and that can be conjugated to a target cell-specific delivery vector, such as an antibody, for delivery to pathogenic cells.

Here described are compounds consisting of the structure

(targeting molecule).sub.m-linker-(targeting molecule).sub.n,

wherein the targeting molecule is a retinoid or a fat soluble vitamin having a specific receptor on the target cell; wherein m and n are independently 0, 1, 2 or 3; and wherein the linker comprises a polyethylene glycol (PEG) or PEG-like molecule, as well as compositions and pharmaceutical formulations including these compounds which are useful for the targeting and delivery of therapeutic agents; and methods of using these compositions and pharmaceutical formulations.

The present invention relates to a long acting biologically active luteinizing hormone (LH) compound comprising an LH agonist linked to a pharmaceutically acceptable molecule providing an in vivo plasma half-life of the LH agonist or LH compound which is increased substantially compared to the in vivo plasma half-life of an LH agonist administered in the same manner as the LH compound. The present invention relates to methods for controlled ovarian stimulation which can be used in conjunction with assisted reproduction technologies such as in vitro fertilisation, intra cytoplasmatic sperm injection, intra uterine insemination and in vitro maturation. In other aspects the invention relates to methods for inducing folliculogenesis and methods for providing luteal support for the corpora lutea.

Novel modulators, including antibodies and derivatives thereof, and methods of using such modulators to treat proliferative disorders are provided.
