This work demonstrated the high efficiency of a sub-milligram-synthesis based medicinal chemistry method. Totally 72 compounds, consisting a tri-substituted pyrrolidine core, were prepared. Around 0.1 mg of each compound was solid-phase synthesized. Based on the additive property of UV absorptions of unconjugated chromophores of a molecule, these compounds were quantified by UV measurement. A hit, whose IC50 value was 1.2 μM in HDAC11 inhibition assays, highlights the applicability of the approach reported here in future optimization works.

The enantioselective syntheses of 3-amino-5-fluoropiperidines and 3-amino-5,5-difluoropiperidines were developed using the ring enlargement of prolinols to access libraries of 3-amino- and 3-amidofluoropiperidines. The study of the physicochemical properties revealed that fluorine atom(s) decrease(s) the pKa and modulate(s) the lipophilicity of 3-aminopiperidines. The relative stereochemistry of the fluorine atoms with the amino groups at C3 on the piperidine core has a small effect on the pK a due to conformationnal modifications induced by fluorine atom(s). In the protonated forms, the C-F bond is in an axial position due to a dipole-dipole interaction between the N-H+ and C-F bonds. Predictions of the physicochemical properties using common software appeared to be limited to determine correct values of pKa and/or differences of pK a between cis- and trans-3-amino-5-fluoropiperidines.

3-Aminopiperidines are of great interest because they can possess a wide range of biological activity depending on the nitrogen substituents. Different approaches their synthesis are presented and the most efficient is a ring expansion of prolinols induce

The quinolinecarboxylic acids constitute a class of extremely potent and orally active broad-spectrum antibacterial agents.These compounds have been shown to inhibit DNA gyrase, a key enzyme in bacterial DNA replication.The 7-(3-aminopyrrolidinyl)quinolone A-60969 (1) is a particularly potent member of this class and is currently undergoing clinical evaluation.We have studied a series of enantiomerically homogeneous (4S)-7-(4-amino-2-substituted-pyrrolidinyl)quinolones in an effort to utilize the 2-position of the pyrrolidine moiety to improve upon the solubility and pharmacokinetic properties of this class of compounds while still maintaining potent antibacterial activity.We have found that the absolute stereochemistry at the 2-position of the pyrrolydine ring is critical to the maintenance of such activity.In this paper, we report the full details of the asymmetric synthesis and the in vitro and in vivo structure-activity relationships of this series of compounds as well as the physiochemical properties, such as water solubility and log P, associated with the structural modifications.We also discuss the pharmacokinetic properties of several of these compounds in mice and the pharmacokinetics of 59, which has the best overall properties of agents in this study, in dog.
