Methods, agents and compositions as in situ vaccine for cancer cell and tumor treatment
This disclosure provides agents, compositions and methods for treating cancer by treating tumor in a subject. The composition comprises cancer cell inactivating agent and immune activity enhancing agent in a sustained release formulation, which can be used as intratumoral injection to convert the treated tumor into an in situ vaccine for cancer. Suitable immune activity enhancing agents include TLR agonist and STING agonist.
Drug Delivery Composition Comprising a Self-Assembled Gelator
This invention discloses drug-delivery compositions, methods of making prodrugs, and methods of drug delivery using a self-assembled gelator. The backbone of the gelator can contain a drug or prodrug, such as acetaminophen or salicin. Additional drugs or agents can be encapsulated in the gelator. Enzymatic or hydrolytic cleavage can be used to release the drugs.
Targeting Ligands
Described are novel targeting ligands that may be linked to compounds, such therapeutic compounds that are useful in directing the compounds to the in vivo target. The targeting ligands disclosed herein can serve to target expression-inhibiting oligomeric compounds, such as RNAi agents, to liver cells to modulate gene expression. The targeting ligands disclosed herein, when conjugated to a therapeutic compound, may be used in a variety of applications, including use in therapeutic, diagnostic, target validation, and genomic discovery applications. Compositions including the targeting ligands disclosed herein when linked to expression-inhibiting oligomeric compounds are capable of mediating expression of target nucleic acid sequences in liver cells, such as hepatocytes, which may be useful in the treatment of diseases or conditions that respond to inhibition of gene expression or activity in a cell, tissue, or organism.
Fluorohydroxyproline derivatives useful in the preparation of proteolysis targeted chimeras
There is provided novel small molecule E3 ubiquitin ligase protein binding ligand compounds, and to their utility in PROteolysis Targeted Chimeras (PROTACs), as well as processes for their preparation thereof, and use in medicine. There is particularly provided novel small molecule E3 ubiquitin ligase protein binding inhibitor compounds based on a fluorohydroxyproline scaffold, to their utility as ligands in synthesizing novel PROTACs, and to synthetic methods therefor.
GLYCOPEPTIDE FOR CONTRAST AGENT TARGETING CANCER CELLS AND CONTRAST AGENT KIT CONTAINING THE SAME
The present disclosure relates to a glycopeptide targeting cancer cells and a contrast agent kit containing the same. The glycopeptide is one wherein an azide reporting monosaccharide is bound to a substrate peptide. As the substrate peptide is specifically cleaved by cathepsin B in cancer cells, an azide reporting monosaccharide is expressed onto the cell surface via metabolic glycoengineering, thereby providing a target for action as a contrast agent. Accordingly, because the azide is exposed to the cell surface only by cathepsin B, as it is specifically expressed in cancer cells, in particular in metastatic cancer cells, while it is limitedly expressed in normal cells and is hardly excreted out the cells, the cancer cells can be selectively imaged by an azide-specific contrast agent.
MULTIVALENT LIGAND-LIPID CONSTRUCTS
Water dispersible, multivalent ligand-lipid constructs that spontaneously and stably incorporate into membranes are disclosed.
DEGRADERS OF CYCLIN-DEPENDENT KINASE 12 (CDK12) AND USES THEREOF
Provided herein are bifunctional compounds with a moiety (e.g., lenalidomide, thalidomide) that is a binder of an E3 ubiquitin ligase (e.g., Cereblon) and another moiety that is a binder of a target protein (e.g., kinase (e.g., CDK (e.g., CDK9 and/or CDK12))) to induce degradation of the target protein CDK9 and/or CDK12. Also provided are pharmaceutical compositions comprising the bifunctional compounds, and methods of treating and/or preventing diseases (e.g., proliferative diseases, such as cancers (e.g., ovarian cancer, breast cancer, or prostate cancer))). Provided also are methods of inducing the degradation of the target protein (e.g., kinase (e.g., CDK (e.g., CDK9 and/or CDK12))), and methods of inducing apoptosis in a cell in a biological sample or subject by administering the bifunctional compound or composition described herein.

NON PEPTIDIC HETEROBIVALENT MOLECULES FOR TREATING INFLAMMATORY DISEASES
The present invention relates to non peptidic, heterobivalent molecules (HBM) that are able to simultaneously bind a surface target protein as well as an endogenous or exogenous human antibody protein and induce immune effector function. More specifically, the present invention relates to agents capable of binding to a chemokine receptor and inducing the depletion of chemokine receptor positive subsets of pathogenic cells in a subject for use in the treatment and/or prevention of cancer, inflammatory, autoimmune and allergic disease.
Compounds and methods for the targeted degradation of enhancer of zeste homolog 2 polypeptide
The present disclosure relates to bifunctional compounds, which find utility as modulators of enhancer of zeste homolog 2 (target protein). In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a Von Hippel-Lindau, cereblon, Inhibitors of Apotosis Proteins or mouse double-minute homolog 2 ligand which binds to the respective E3 ubiquitin ligase and on the other end a moiety which binds the target protein, such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of target protein. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of target protein. Diseases or disorders that result from aggregation or accumulation of the target protein are treated or prevented with compounds and compositions of the present disclosure.
