Treatment of cancer cells by clinically approved hexyl ester of 5-aminolevulinic acid (ALA-Hex) induces accumulation of fluorescent porphyrins in tumors. This allows fluorescence photodiagnosis (PD) of bladder cancer by blue light illumination. However, PD of other cancers is hampered by acute toxicity of the compound limiting its use to local applications. We have designed and synthesized a new prodrug of ALA-Hex that tackles the stability-activity paradox of amino-modified 5-ALA prodrugs. The glucuronide prodrug Glu-ALA-Hex demonstrates excellent stability under physiological conditions and activation in the presence of the target enzyme. β-glucuronidase-triggered release of 5-ALA is programmed to yield fluorescence in tumor environment with elevated β-glucuronidase activity, a characteristic of many solid tumors. Glu-ALA-Hex produces similar levels of fluorescence as ALA-Hex in breast cancer MCF7 cells in vitro but with much lower non-specific cell toxicity.
β-Glucuronidase triggers extracellular MMAE release from an integrin-targeted conjugate

A non-internalizing αvβ3 integrin ligand was conjugated to the anticancer drug MMAE through a β-glucuronidase-responsive linker. In the presence of β-glucuronidase, only the conjugate bearing a PEG4 spacer inhibited the proliferation

Most anticancer agents are hydrophobic and can easily penetrate the tumor cell membrane by passive diffusion. This may impede the development of highly effective and tumor-selective treatment options. A hydrophilic β-glucuronidase-cleavable linker was used to connect the highly potent antimitotic agent cryptophycin-55 glycinate with the αvβ3 integrin ligand c(RGDfK). Incorporation of the self-immolative linker containing glucuronic acid results in lower cytotoxicity than that of the free payload, suggesting that hydrophilic sugar linkers can preclude passive cellular uptake. In vitro drug-release studies and cytotoxicity assays demonstrated the potential of this small molecule–drug conjugate, providing guidance for the development of therapeutics containing hydrophobic anticancer drugs.

COMPOUNDS, COMPOSITIONS, METHODS, AND USES FOR TREATING CANCER AND IMMUNOLOGICAL DISORDERS
-
, (2020/02/06)
The present disclosure provides novel polypeptide-therapeutic compound or hormone-therapeutic compound conjugates using cleavable or non-cleavable linkers, whereby the polypeptide or hormone serves to target specific cells using receptor expression on the targeted cell to bind the ligand (polypeptide or hormone) carrying the therapeutic compound unlike antibody drug conjugates. Upon binding, the ligand and the therapeutic compound (multiples of the therapeutic compound in some embodiments) enter the cell by receptor-mediated endocytosis, and release drugs conjugated to the ligand by linkers, to interact with intracellular components to enhance, restore, or block a signal transduction process. The ligands for the polypeptide-therapeutic compound or hormone-therapeutic compound conjugates include, but are not limited to: cytokines, growth factors and hormones among other proteins with corresponding cell surface specific receptors. The disorders targeted by such polypeptide-therapeutic compound or hormone-therapeutic compound conjugates include, but are not limited to: immunological disorders (e.g., allergy and autoimmune disorders) and cancer.
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.
