APC-3316 is a vinyl sulfone cystein protease inhibitor. It is a potent, irreversible cysteine protease inhibitor and a potent and selective CCR4 antagonist. Its therapeutic targets are cruzain, a cysteine protease of the protozoan parasite Trypanosoma cruzi, and cathepsins B and L, which are associated with cancer progression. It was discontinued after preclinical trials in Chagas disease in USA.

MCD-386CR (CDD-0102A) is a functionally selective agonist with partial agonist activity at M1 muscarinic receptors, weak activity at M3 receptors, and no activity at other muscarinic receptor subtypes. In preclinical studies, it enhances memory function in animal models of Alzheimer's disease. MCD-386CR (CDD-0102A) received orphan drug designation from FDA in 2011. The drug is intended to treat progressive supranuclear palsy, a degenerative brain disease that affects balance, walking, speech, cognition, and eye movements.
