  Leukotriene receptor antagonists. 1. Synthesis and structure-activity relationships of alkoxyacetophenone derivatives

  摘要：

  A series of derivatives of 2,4-dihydroxy-3-propylacetophenone(1) were prepared and examined for their ability to block leukotriene D4 (LTD4) induced contraction of guinea pig ileum. Straight-chain carboxylic acids where the carboxyl group was separated from the acetophenone moiety by varying numbers of methylenes were evaluated, and maximum activity was obtained with the pentamethylene acid (6). Examination of ring substitution showed that the 2-propyl-3-hydroxy-4-acetyl substitution pattern was required for maximum LTD4 antagonist activity. Additional chain terminal groups were examined, and the acidic 5-tetrazolyl group separated from the acetophenone moiety by four to seven methylenes (26, 23, 27, 28) gave excellent in vitro and in vivo activities. Compound 26 (LY171883) had the best balance of in vitro and in vivo activity. It lacked bronchospastic activity at the doses administered and has been chosen for clinical evaluation.

  20-Tetrakis(o-pivalamidophenyl)porphyrins (TPVP) and their iron(II) derivatives bearing a proximal imidazole covalently bound at the 2-(β-pyrrolic) position have been synthesized. The visible absorption maxima (λmax) of the 2-substituted TPVP with an electron withdrawing group attached is shifted toward the red region (7–11 nm) compared with that of the original TPVP. The iron(II) complexes having an imidazolyl
