Ion chemistry of phthalamic acids. III. The origin of [M 1]+ ions under electron impact
摘要:
AbstractElectron impact mass spectra and collisional activation/mass‐analysed ion kinetic energy spectra of some phthalamic acids and their deuterium labelled analogues suggested that the genesis of [M 1]+ ions is due to the loss of an aromatic hydrogen ortho to the amidic group, as for aromatic amides and thioamides.

In our previous study on discovering novel types of CCR3 antagonists, we found a fluoronaphthalene derivative (1) that exhibited potent CCR3 inhibitory activity with an IC(50) value of 20 nM. However, compound 1 also inhibited human cytochrome P450 2D6 (CYP2D6) with an IC(50) value of 400 nM. In order to reduce its CYP2D6 inhibitory activity, we performed further systematic structural modi. cations on 1. In particular, we focused on reducing the number of lipophilic moieties in the biphenyl part of 1, using Clog D(7.4) values as the reference index of lipophilicity. This research led to the identification of N-(3-exo)-8-[(6-fluoro-2-naphthyl)methyl]-8-azabicyclo[3.2.1]oct-3-yl}-3-(piperidin-1-ylcarbonyl)isonicotinamide 1-oxide (30) which showed comparable CCR3 inhibitory activity (IC(50) = 23 nM) with much reduced CYP2D6 inhibitory activity (IC50 = 29,000 nM) compared with 1.
