Novel 1H-imidazol-2-amine derivatives as potent and orally active vascular adhesion protein-1 (VAP-1) inhibitors for diabetic macular edema treatment
摘要:
Novel thiazole derivatives were synthesized and evaluated as vascular adhesion protein-1 (VAP-1) inhibitors. Although we previously identified a compound (2) with potent VAP-1 inhibitory activity in rats, the human activity was relatively weak. Here, to improve the human VAP-1 inhibitory activity of compound 2, we first evaluated the structure-activity relationships of guanidine bioisosteres as simple small molecules and identified a 1H-benzimidazol-2-amine (5) with potent activity compared to phenylguanidine (1). Based on the structure of compound 5, we synthesized a highly potent VAP-1 inhibitor (37b; human IC50 = 0.019 mu M, rat IC50 = 0.0051 mu M). Orally administered compound 37b also markedly inhibited ocular permeability in streptozotocin-induced diabetic rats after oral administration, suggesting it is a promising compound for the treatment of diabetic macular edema.

The disclosure provides nicotinamide riboside (NR), the reduced form of NR (NRH), nicotinic acid riboside (NAR), the reduced form of NAR (NARH), derivatives thereof, compositions thereof and uses thereof. The NR and NAR derivatives have improved stability and bioavailability compared to NR and NAR. NR, NRH, NAR, NARH, and derivatives thereof can increase cellular NAD
+
levels and enhance mitochondrial and cellular function and cell viability. Therefore, NR, NRH, NAR, NARH, and derivatives thereof, whether alone or in combination with one or more additional therapeutic agents (e.g., a mitochondrial uncoupler or/and a PARP inhibitor), are useful for treating mitochondrial diseases, mitochondria-related diseases and conditions, metabolic disorders, and other disorders and conditions.
