FLOTEGATIDE is a cyclic tripeptide with arginine-glycine-aspartic acid (R-G-D) motif. Its 18F radiolabelled form is a positron emission tomography (PET) tracer targeting integrin alpha-V/beta-3.

MK-2748 is hepatitis C Virus NS3/4a Protease Inhibitor patented by pharmaceutical company Merck & Co Co for the treatment of hepatitis C virus infection.

Modimelanotide is a melanocortinergic peptide drug derived from α-melanocyte-stimulating hormone (α-MSH) which was under development for the treatment of acute kidney injury. Modimelanotide had promising preclinical data, and a Phase II trial in patients undergoing cardiopulmonary bypass surgery showed a reduced incidence of acute kidney injury in subjects that received Modimelanotide. However, a Phase IIb, multicenter study of Modimelanotide in patients with chronic kidney disease who underwent cardiopulmonary bypass surgery failed to show a significant reduction in the incidence of acute kidney injury in subjects who received the drug, both by serum creatinine measurements and by novel biomarkers of tubular injury.

Fasidotril is a diester prodrug of the active metabolite fasidotrilat. Fasidotrilat inhibited both angiotensin I converting enzyme (ACE, EC 3.4.25.1) and neprilysin (NEP, EC 3.4.24.11, also named neutral endopeptidase, enkephalinase, or atriopeptidase) at nanomolar concentrations (Ki = 9.8 nM against ACE and 5.1 nM against NEP) Fasidotril was being developed for the treatment of myocardial infarction, congestive heart failure and myocardial infarction.
