Dengue virus protease is a promising target for the development of antiviral drugs. We describe here a two-step rational optimization that led to the discovery of the potent inhibitor 35 with nanomolar binding affinity at dengue protease serotype 2 (IC50 = 0.6 渭M, Ki = 0.4 渭M). First, a large number of natural and non-natural amino acids were screened at the C-terminal position of the previously reported, canonical peptide sequence (Cap-Arg-Lys-Nle-NH2). Compared to the reference compound 1 (Bz-Arg-Lys-Nle-NH2, IC50 = 13.3 渭M), a 4-fold higher inhibitory potential was observed with the incorporation of a C-terminal phenylglycine (compound 9, IC50 = 3.3 渭M). Second, we applied fragment merging of 9 with the previously reported thiazolidinedione peptide hybrid 33 (IC50 = 2.5 渭M). This approach led to the fusion of two inhibitor-fragments with micromolar affinity into a 20-fold more potent, competitive inhibitor of dengue protease. This study involved multiple reactions and reactants, such as (S)-1-(((9H-Fluoren-9-yl)methoxy)carbonyl)piperidine-2-carboxylic acid (cas: 86069-86-5Related Products of 86069-86-5).
(S)-1-(((9H-Fluoren-9-yl)methoxy)carbonyl)piperidine-2-carboxylic acid (cas: 86069-86-5) belongs to piperidine derivatives.Piperidine is a key saturated heterocyclic scaffold found in several of the top-selling small molecule pharmaceuticals and natural alkaloids, with a diverse range of biological activities. Piperidine prefers a chair conformation, similar to cyclohexane. Unlike cyclohexane, piperidine has two distinguishable chair conformations: one with the N鈥揌 bond in an axial position, and the other in an equatorial position.Related Products of 86069-86-5
