Analogs of platelet activating factor. 8. Antagonists of PAF containing an aromatic ring linked to a pyridinium ring
摘要:
A series of platelet activating factor (PAF) antagonists containing a quaternary pyridinium ring connected through an amide, imide, or carbamate linkage to a substituted aromatic ring was prepared. Of these compounds, those containing a branched imide linkage of the form (CON-(COCH3)CH2, 37-51, and 59) generally showed excellent PAF antagonist properties in vitro. Structure-activity relationships within this series of compounds were studied extensively with respect to substituents and the position of substitution in both the aromatic and pyridinium rings. Several of these compounds (40 and 44) showed in vitro PAF antagonism at less than 0.1 muM and are as potent as CV-6209, the most potent PAF antagonist reported in the literature. Less active PAF antagonists were those bearing simple amide linkages (20-23, 27-29, and 31-35), linear imide linkages (62-63), or carbamate linkages (66 and 68), between the two aromatic rings. A number of our PAF antagonists were tested in vivo in mice and rabbits for their ability to protect these animals against a lethal injection of PAF. Those antagonists that are particularly potent (IC50 <0.1 muM) provide excellent protection against an LD97 dose of PAF in rabbits. The relationships between structure and activity in vitro and in vivo are presented and compared to literature standards.

report the synthesis and pharmacological characterization of ATX inhibitors based on the 4‐tetradecanoylaminobenzylphosphonic acid scaffold, which was previously found to lack sufficient stability in cellular systems. The new 4‐substituted benzylphosphonic acid and 6‐substituted naphthalen‐2‐ylmethylphosphonic acid analogues block ATX activity with Ki values in the low micromolar to nanomolar range against
Stabilized benzyl phosphonic acid and naphthyl phosphonic acid analog compounds are effective in inhibiting the activity of autotaxin.
