Background: Ligands consisting of two aryl moieties connected via a short spacer were shown to be potent inhibitors of monoamine oxidases (MAO) A and B, which are known as suitable targets in treatment of neurological diseases. Based on this general blueprint, we synthesized a series of 66 small aromatic amide derivatives as novel MAO A/B inhibitors. Methods: The compounds were synthesized, purified and structurally confirmed by spectroscopic methods. Fluorimetric enzymological assays were performed to determine MAO A/B inhibition properties. Mode and reversibility of inhibition was determined for the most potent MAO B inhibitor. Docking poses and pharmacophore models were generated to confirm the in vitro results. Results: N-(2,4-Dinitrophenyl)benzo[d][1,3]dioxole-5-carboxamide (55, ST-2043) was found to be a reversible competitive moderately selective MAO B inhibitor (IC50 = 56 nM, Ki = 6.3 nM), while N-(2,4-dinitrophenyl)benzamide (7, ST-2023) showed higher preference for MAO A (IC50 = 126 nM). Computational analysis confirmed in vitro binding properties, where the anilides examined possessed high surface complementarity to MAO A/B active sites. Conclusion: The small molecule anilides with different substitution patterns were identified as potent MAO A/B inhibitors, which were active in nanomolar concentrations ranges. These small and easily accessible molecules are promising motifs, especially for newly designed multitargeted ligands taking advantage of these fragments.
Lead optimization of the VU0486321 series of mGlu1 PAMs. Part 3. Engineering plasma stability by discovery and optimization of isoindolinone analogs

This Letter describes the further lead optimization of the VU0486321 series of mGlu1 positive allosteric modulators (PAMs), focused on addressing the recurrent issue of plasma instability of the phthalimide moiety. Here, we evaluated a number of phthalimide bioisosteres, and ultimately identified isoindolinones as the ideal replacement that effectively address plasma instability, while maintaining acceptable mGlu1 PAM potency, DMPK profile, CNS penetration and mGluR selectivity.
A catalytic and tert-butoxide ion-mediated amidation of aldehydes with para-nitro azides
Carbone, Giorgio,Burnley, James,Moses, John E.
supporting information, p. 2759 - 2761 (2013/04/10)
We report here a new catalytic reaction in which, para-nitro azides are acylated by aldehydes to produce amides and molecular nitrogen in a single step. The transformation is believed to proceed via an electron transfer process mediated by the tert-butoxide ion, and catalysed by a thiazolium salt derived species. The Royal Society of Chemistry 2013.

Mild, efficient and selective nitration of anilides, non-activated and moderately activated aromatic compounds with ammonium molybdate and nitric acid as a new nitrating agent

Ammonium molybdate [Mo(VI)] is operationally simple, environmentally safe and inexpensive reagent. Regioselective nitration of anilides, non-activated and moderately activated aromatic compounds could be afforded by employing ammonium molybdate and nitric acid as mild and effective nitrating agent. This procedure works efficiently under reflux conditions to prepare mononitroderivatives of anilides, non-activated and moderately activated aromatic compounds in good to excellent yield with high regioselectivity.
