Dexecadotril is powerful and selective inhibitor of neprilysin. It is anti-hypotensive agent. Dexecadotril was found to possess chemoprotective activity. It might be biologically active against multiple myeloma. It was under clinical evaluation as an intestinal antisecretatory agent.

Ampion (LMWF-5A) is a low molecular weight fraction of human serum albumin (HSA) currently being developed for the treatment of pain due to osteoarthritis of the knee. The primary constituent ingredient of Ampion is aspartyl-alanyl diketopiperazine, or DA-DKP, an endogenous immunomodulatory molecule derived from the N-terminus of HSA. Based on published pre-clinical and clinical research, DA-DKP plays a significant role in the regulation of inflammation. DA-DKP is believed to reduce inflammation by suppressing pro-inflammatory cytokine production in T-cells. Ampion also contains other known small molecules that confer anti-inflammatory effects to complement the activity of DA-DKP and derive demonstrated in-vitro and in-vivo effects. Ampio is currently developing Ampion as an intra-articular injection to treat osteoarthritis of the knee, and the final US pivotal trial is underway. Additional pre-clinical and clinical studies have been completed or are underway for Ampion and other chronic inflammatory conditions.
