Piperidine scaffold as the novel P2-ligands in cyclopropyl-containing HIV-1 protease inhibitors: Structure-based design, synthesis, biological evaluation and docking study was written by Zhou, Huiyu;Zhu, Mei;Ma, Ling;Zhou, Jinming;Dong, Biao;Zhang, Guoning;Cen, Shan;Wang, Yucheng;Wang, Juxian.

A series of potent HIV-1 protease inhibitors, containing diverse piperidine analogs as the P2-ligands, 4-substituted phenylsulfonamides as the P2′-ligands and a hydrophobic cyclopropyl group as the P1′-ligand, were designed, synthesized and evaluated in this work. Among these twenty-four target compounds, many of them exhibited excellent activity against HIV-1 protease with half maximal inhibitory concentration (IC50) values below 20 nM. Particularly, compound I containing a (R)-piperidine-3-carboxamide as the P2-ligand and a 4-methoxylphenylsulfonamide as the P2′-ligand exhibited the most effective inhibitory activity with an IC50 value of 3.61 nM. More importantly, I exhibited activity with inhibition of 42% and 26% against wild-type and Darunavir (DRV)-resistant HIV-1 variants, resp. Addnl., the mol. docking of I with HIV-1 protease provided insight into the ligand-binding properties, which was of great value for further study. In the experiment, the researchers used many compounds, for example, (R)-1-(tert-Butoxycarbonyl)piperidine-3-carboxylic acid (cas: 163438-09-3Electric Literature of C11H19NO4).
(R)-1-(tert-Butoxycarbonyl)piperidine-3-carboxylic acid (cas: 163438-09-3) belongs to piperidine derivatives. Piperidine has a role as a reagent, a protic solvent, a base, a catalyst, a plant metabolite, a human metabolite and a non-polar solvent. Piperidine derivatives bearing a masked aldehyde function in the ε-position are easily transformed into quinolizidine compounds through intramolecular reductive amination.Electric Literature of C11H19NO4
