  Analogs of platelet activating factor. 6. Mono- and bis-aryl phosphate antagonists of platelet activating factor

  摘要：

  A series of aryl phosphoglyceride (3, 19-6 1) and bis-aryl phosphate (67-135) antagonists of platelet activating factor (PAF) were prepared. A group of four bifunctional phosphorus reagents (5a-c and 7) were developed that allowed the preparation of these aryl phosphates in which the position of aromatic substitution can be varied. These compounds were examined for their ability to inhibit PAF-induced platelet aggregation of rabbit platelets. Selected compounds were also evaluated for their ability to displace [H-3]PAF from its receptor on rabbit platelets. These in vitro data were compared to similar data obtained for a number of known PAF antagonists. The compounds were evaluated in vivo, in both the mouse and rabbit, for their ability to prevent death induced by a lethal challenge of PAF. The relationships between the biological activity and the nature, lipophilicity, and position of substituents of the aromatic rings were studied. Compound 105 (CL 184005) has been selected to undergo further development as a potential therapeutic agent for the treatment of septic shock in man.

• Mesogenic bis-heterocycles incorporating both pyrazole and isoxazole

  日期：2015.8

  Two new series of mesogenic bis-heterocyclic derivatives containing pyrazoles and isoxazoles 1a-b were reported. One single crystallographic structure of mesogenic 2a (n=8) was determined by X-ray analysis, and it crystallizes in a triclinic space group P-1, with a=7.0511(2), b=7.6303(2) and c=21.2143(5) angstrom, and Z=2. The crystal was considered as slightly bent-shaped molecule with a molecular length of ca. similar to 24.9 angstrom. A dimeric correlated structure induced by H-bonds was observed in the crystal lattice, which was favorable to the formation of mesophases. All compounds 1-2 exhibited N, SmA, N/SmC or SmA/SmC phases, as expected for linear-shaped molecules. All compounds 1 have higher clearing temperatures and wider ranges of mesophases than those of their precursors 2, which might be attributed to have higher dipoles polarized by two heterocyclic rings in 2.

• A SAR study on a series of synthetic lipophilic chalcones as Inhibitor of transcription factor NF-κB

  To define the structural features responsible for the activity of 2,4-dihydroxy-6-isopentyloxychalcone, a newly established inhibitor of LPS induced NF-kappa B activation (IC50 = 10 mu M), a series of its analogues was prepared and studied for their in vitro activities against LPS induced NF-kappa B inhibition in RAW 264.7 cells. Among the synthesized derivatives, (E)-1-(2-(decyloxy)-6-hydroxyphenyl)-3-(4-hydroxyphenyl)prop-2-en-1-one (1050 = 2.7 mu M) and (E)-1-(2-hydroxy-6-(tetradecyloxy)phenyl)-3-(4-hydroxyphenyl)prop-2-en-1-one (IC50 = 4.2 mu M) showed the most potent inhibition. The SAR studies confirmed that the length (C-8-C-14) and C-6 position of linear alkyl chain of ring A is an important factor for the inhibitory activity. Hydroxyl group and its location at 4-position on ring B is also important for the inhibition. The alpha,beta-unsaturated ketone moiety appears as a crucial motif of chalcones for the activity.
