Cell penetrating protein-antibody conjugates and methods of use
Provided herein are cell penetrating conjugates. The conjugates include non-cell penetrating proteins connected through a phosphorothioate nucleic acid, wherein the phosphorothioate nucleic acid enhances intracellular delivery of the non-cell penetrating proteins. Also provided are methods and kits including the conjugates provided herein.
SITE-SPECIFIC ANTIBODY CONJUGATION AND ANTIBODY-DRUG CONJUGATE AS SPECIFIC EMBODIMENT THEREOF
The present invention relates to technology capable of labeling a certain site of an antibody with a certain number of chemical functional groups or cargo moieties. The present invention may provide an antibody product having high uniformity. The present invention may provide an antibody product whose antibody functions are not degraded. That is, the present invention may provide an antibody product whose antibody binding affinity and half-life are not degraded. The present invention is of great significance as being the first technology allowing site-specific labeling of an antibody without any complicated processes.
CONJUGATES COMPRISING A PHOSPHORUS (V) AND A CAMPTOTHECIN MOIETY
The present invention relates to a conjugate having the formula (I):
##STR00001##
wherein a receptor binding molecule (RBM) is connected with a camptothecin moiety (C). The present invention also relates to intermediates for producing the same, methods of preparing the same, pharmaceutical compositions comprising the same, as well as uses thereof.
LINKERS FOR IMPROVING THE STABILITY OF BIOCONJUGATES AND THE SELECTIVITY OF PAYLOAD RELEASE
Disclosed herein are linker architectures for conjugates that do not rely on the SAR of the cleavable trigger or the large steric bulk of a closely positioned antibody to alter payload release. These linkers are expected to reduce off-target payload release facilitated by extracellular cathepsins, and may also be applicable to conjugates of antibody fragments that lack the steric protection from a full antibody. In addition, the linkers disclosed herein are expected to provide more selective intracellular payload release. Thus, these linkers can function synergistically with the targeting vector to confer differential payload release rates in vivo that improve the selectivity of intracellular payload release and reduce off target toxicity.
Activated formylglycine-generating enzymes and methods of producing and using the same
The present disclosure provides activated formylglycine-generating enzymes (FGE), methods of producing activated FGE, and their use in methods of producing a protein comprising a formylglycine (FGly) residue. The methods of producing activated FGE, as well as methods of use of activated FGE in producing FGly-containing proteins, include both cell-based and cell-free methods. Compositions and kits that find use, e.g., in practicing the methods of the present disclosure are also provided.
PRO-CYCLIC DINUCLEOTIDES AND PRO-CYCLIC DINUCLEOTIDE CONJUGATES FOR CYTOKINE INDUCTION
The present invention provides a Pro-cyclic dinucleotide (Pro-CDN) comprising a STING agonist cyclic dinucleotide which is coupled to a linker system. The Pro-CDNs of the present invention can be metabolized at a targeted site into CDNs and exert their full immunomodulatory effects at said targeted site. The present invention also provides conjugates wherein a Pro-CDN is conjugated to a Biologically Active Molecule (BAM) such as e.g. a cytotoxic molecule, a lipid, a protein, a peptide, a nucleic acid, a sugar or a PRR ligand. The invention provides also methods related to the use of such compounds to perform their activities at their targeted sites, to exert cytotoxic, cytostatic or immunomodulatory effects, to treat or to prevent diseases such as cancers, immunological disorders or infections.
USE OF ANTIBODY DRUG CONJUGATES COMPRISING TUBULIN DISRUPTING AGENTS TO TREAT SOLID TUMOR
The present disclosure, relates, in general to methods for treating solid tumors comprising administering a drug-linker-antibody conjugate, wherein the drug is a tubulin disrupting agent.
CONJUGATES UNDERGOING INTRAMOLECULAR REARRANGEMENTS
The present invention relates to conjugates and pharmaceutically acceptable salts thereof, reagents, intermediates, methods for the synthesis of said conjugates, pharmaceutical compositions comprising said conjugates and the use of said conjugates.
VIA CYCLOADDITION BILATERALLY FUNCTIONALIZED ANTIBODIES
The present invention provides antibody-payload conjugates having a payload-to-antibody ratio of 1. The antibody-payload conjugate is according to structure (1):
##STR00001##
wherein: a, b, c and d are each independently 0 or 1; e is an integer in the range of 0-10; L.sup.1, L.sup.2 and L.sup.3 are linkers; D is a payload; BM is a branching moiety; Su is a monosaccharide; G is a monosaccharide moiety; GlcNAc is an N-acetylglucosamine moiety; Fuc is a fucose moiety; Z are connecting groups.
The invention further provides a method for preparing the antibody-payload conjugate according to the invention, an intermediate compound in that preparation method, and medical uses of the antibody-payload conjugate according to the invention.
