Hangzhou Unogen Biotech Ltd. has divulged protein arginine N-methyltransferase 5 (PRMT5) inhibitors reported to be useful for the treatment of lymphoma.

Researchers at Albert-Ludwigs-Universität Freiburg and Deutsches Krebsforschungszentrum (DKFZ) have disclosed drug conjugates comprising fluorescent-labeled dye covalently linked to a radionuclide and a ligand targeting glutamate carboxypeptidase II (NAALADase; NAAG peptidase, FOLH1; PSMA) acting as positron-emission tomography (PET) and fluorescent imaging agents for diagnosis and treatment of prostate cancer.

Fibroblast activation protein (FAP) is a serine protease that is highly overexpressed in the stroma of most epithelial-derived tumors – including pancreatic, breast and colorectal cancers – in the context of cancer-associated fibroblasts (CAFs).

Simultaneous inhibition of phosphoinositide 3-kinase (PI3K) and histone deacetylase (HDAC) is considered a good strategy in cancer treatment, although current PI3K/HDAC dual inhibitors have limitations, such as low selectivity and moderate toxicity levels.

A new degrader strategy has been previously proposed to mitigate platelet toxicity associated with Bcl-xL degraders. This strategy consists of selectively degrading Bcl-xL by the von Hippel-Lindau protein (VHL) E3 ligase in tumor cells, but not in platelets, which minimally express VHL. DT-2216 was developed as the first Bcl-xL degrader of this kind; however, this clinical candidate has still shown some platelet toxicity in vivo.

Wall Street will be watching closely for such adverse effects as anemia that foiled Gilead Sciences Inc.’s CD47-binding magrolimab earlier this year, but so far Shattuck Labs Inc.’s SL-172154 looks strong in combination with azacitidine to treat front-line higher-risk myelodysplastic syndrome (HR-MDS) and TP53-mutant (TP53m) acute myeloid leukemia (AML).
