Abstract
Disclosed herein are compositions comprising immune-activating agents that bind the tumor cell surface in the absence of a tumor-targeting protein component. Described herein are methods and compositions for targeting a TLR or STING agonist to tumor cells and/or cells in the tumor microenvironment. It is hypothesized that the metabolic stress of tumor growth also produces an excess of unpaired cysteines on cell surface proteins relative to the rest of the body. Therefore, this chemistry can be used with compounds that would preferentially target unpaired cysteines on cell surface proteins.
Claims75
A polymer comprising the structure (I):
- W, Y, and X are each independently a monomer unit of a polymer;
- A comprises a group that binds to an Antigen Presenting Cell (APC) mannose receptor;
- Z comprises a TLR or STING agonist;
- B comprises a pyridyl disulfide moiety or a maleimide moiety;
- m is an integer ranging from 0 to 150;
- p is an integer ranging from 0 to 10;
- and
- b is an integer ranging from 1 to 10.
A compound comprising:
- wherein L is a linker, T is a TLR or STING agonist, and i is 0 or 1.
A compound comprising:
- wherein L is a linker, T is a TLR or STING agonist, and i is 0 or 1.
The compound of claim 46 or 47, wherein the CpG TLR agonist comprises a phoshorothioated backbone.
