21). A series of small molecule PSMA inhibitors with high af-finity (in the low nanomolar range) and selectivity also have been explored for selective lysis or imaging of PSMA+ prostate cancer cells (18, 22, 23). Because of their small size, such small mole-cule-based targeting agents (peptides…

SAINT-PREX, Switzerland–(BUSINESS WIRE)–Ferring Pharmaceuticals and Enteris BioPharma, Inc. announced today. strategy involving Peptelligence™, its peptide and small molecule oral drug delivery.

The impact of PD-1 immune checkpoint therapy prompts exploration of other strategies to downregulate PD-1 for cancer therapy. We previously showed that the serine/threonine kinase, glycogen synthase kinase, GSK-3α/β, is a central regulator of PD-1 transcription in CD8+ T cells. Here, we show that the use of small-molecule inhibitors of GSK-3α/β (GSK-3i) to reduce pcdc1 (PD-1) transcription.
