Provided herein are compounds, trifunctional antibody products thereof, and methods and pharmaceutical compositions for use in treatment of inflammatory and/or proliferative diseases

The invention relates to novel benzodiazepine derivatives with antiproliferative activity and more specifically to novel benzodiazepines of formula (I) and (II), in which the diazepine ring (B) is fused with a heterocyclic ring (CD), wherein the heterocyclic ring is bicyclic or a compound of formula (III), in which the diazepine ring (B) is fused with a heterocyclic ring (C), wherein the heterocyclic ring is monocyclic. The invention provides cytotoxic dimers of these compounds. The invention also provides conjugates of the monomers and the dimers. The invention further provides compositions and methods useful for inhibiting abnormal cell growth or treating a proliferative disorder in a mammal using the compounds or conjugates of the invention. The invention further relates to methods of using the compounds or conjugates for in vitro, in situ, and in vivo diagnosis or treatment of mammalian cells, or associated pathological conditions.

Disclosed is an IgG Fc fragment useful as a drug carrier. A recombinant vector expressing the IgG Fc fragment, a transformant transformed with the recombinant vector, and a method of preparing an IgG Fc fragment are disclosed. When conjugated to a certain drug, the IgG Fc fragment improves the in vivo duration of action of the drug and minimizes the in vivo activity reduction of the drug.

Processes are described for the preparation of F-benzoxazinorifamycin I:

##STR00001##

and intermediates for conjugation with an antibody.

This application describes a method of using gold nanoparticle (GNP)-targeted pulsed laser technology to enhance antibiotic efficacy against multidrug resistant biofilms. The application also teaches a method for treating topic wound infection using GNP-targeted laser therapy combined with antibiotics treatments.

A payload of drug conjugated to a targeting ligand specifically designed to deliver to exhausted CAR T cells to rejuvenate these CAR T cells is provided herein. The targeted CAR T cells are modified with a fusion receptor which can bind to the targeting ligand and internalize the conjugated payload of drug to execute its regulatory function to exhausted CAR T cell.

The invention relates generally to polypeptides that include a cleavable moiety that is a substrate for at least one protease selected from matriptase and u-plasminogen activator (uPA), to activatable antibodies and other larger molecules that include the cleavable moiety that is a substrate for at least one protease selected from matriptase and u-plasminogen activator, and to methods of making and using these polypeptides that include a cleavable moiety that is a substrate for at least one protease selected from matriptase and u-plasminogen activator in a variety of therapeutic, diagnostic and prophylactic indications.

The disclosure relates to an anti-Pseudomonas PSL binding molecule and uses thereof, in particular, in prevention and treatment of Pseudomonas infection. Furthermore, the disclosure provides compositions and methods for preventing and treating Pseudomonas infection.

The present disclosure provides compositions and methods for efficient and effective protein delivery in vitro and in vivo. In some aspects, proteins are reversibly crosslinked to each other and/or modified with functional groups and protected from protease degradation by a polymer-based or silica-based nanoshell.

The present invention relates to biomolecule conjugates which comprise a biomolecule wherein at least one non-natural amino acid (NNAA) is integral to the structure of the biomolecule and wherein the NNAA is a point of attachment of a linker to which a payload, particularly a cytotoxic agent, is attached. More specifically, this invention relates to conjugates of cell-binding agents and active release products comprising cytotoxic agents wherein the conjugates are produced by means of a cycloaddition reaction. Methods of production, pharmaceutical compositions and methods of use are provided.
