  Benzophenone dicarboxylic acid antagonists of leukotriene B4. 2. Structure-activity relationships of the lipophilic side chain

  摘要：

  A series of lipophilic benzophenone dicarboxylic acid derivatives were found to inhibit the binding of the potent chemotaxin leukotriene B4 (LTB4) to its receptor on intact human neutrophils. Activity at the LTB4 receptor was determined by using a [3H]LTB4-binding assay. The structure-activity relationship for the lipophilic side chain was systematically investigated. Compounds with n-alkyl side chains of varying lengths were prepared and tested. Best inhibition of [3H]LTB4 binding was observed with the n-decyl derivative. Analogues with alkyl chains terminated with an aromatic ring showed improved activity. The 6-phenylhexyl side chain was optimal. Substitution on the terminal aromatic ring was also evaluated. Methoxyl, methylsulfinyl, and methyl substituents greatly enhanced the activity of the compound. For a given substituent, the para isomer had the best activity. Thus the nature of the lipophilic side chain can greatly influence the ability of the compounds to inhibit the binding of LTB4 to its receptor on intact human neutrophils. The most active compound from this series, 84 (LY223982), bound to the LTB4 receptor with an affinity approaching that of the agonist.

  A series of erythromycin A 9-O-substituted oxime ether derivatives have been synthesized and evaluated for antibacterial activity against Mycobacterium avium complex (MAC) and Staphylococcus aureus. These compounds possessed stronger in vitro activity against MAC including macrolide-resistant strains than clarithromycin (2), although in vitro antibacterial activities of these compounds were less than that of 2 against Staphylococcus aureus. Our studies found that several factors contribute to the antibacterial activity against MAC. The length and spatial orientation of the substituent at 9-position were found to significantly influenced the anti-MAC activity, especially against macrolide-resistant strains. Of all the compounds prepared, erythromycin A 9-[O-(4-phenylbutyl)oxime] (12q) and erythromycin A 9-[O-(3-phenoxypropyl)oxime] (12t) possessed 16 times stronger antibacterial activity than 2 against clarithromycin-resistant strains. Surprisingly, the minimum inhibitory concentrations (MICs) of 12q and 12t against the resistant strains were almost same as those against the susceptible strains. These results suggest that the erythromycin A 9-O-substituted oxime ether derivatives would be promising macrolide antibiotics.

  一系列红霉素A 9-O-取代的肟醚衍生物已被合成，并评估其对鸟分枝杆菌复合体（MAC）和金黄色葡萄球菌的抗菌活性。这些化合物在体外对MAC，包括大环内酯耐药株的活性，强于克拉霉素（2），尽管这些化合物对金黄色葡萄球菌的体外抗菌活性低于2。我们的研究发现，多个因素影响对MAC的抗菌活性。位于9位的取代基的长度和空间取向显著影响抗MAC活性，尤其是对大环内酯耐药株的活性。在所有合成的化合物中，红霉素A 9-[O-(4-苯基丁基)肟]（12q）和红霉素A 9-[O-(3-苯氧基丙基)肟]（12t）对克拉霉素耐药株的抗菌活性是2的16倍。令人惊讶的是，12q和12t对耐药株的最低抑菌浓度（MICs）几乎与对敏感株的浓度相同。这些结果表明，红霉素A 9-O-取代的肟醚衍生物可能成为有前景的大环内酯抗生素。
