  摘要：

  合成了 2，3-二氢苯并呋喃-2-羧酸，并在其 4-位上用电负性的硝基、酰基和氨基磺酰基取代。此外，还采用清除法测试了经氧化乐果处理的大鼠腹腔内的尿尿素活性。与相应的 5-硝基化合物（7b、18b、19b 和 20）相比，4-硝基化合物（11b、12b、13b 和 14b）显示出更强的利尿活性。尽管有报告称 5-酰基化合物具有强效的盐渍化活性，但 4-酰基化合物（41a 和 b）的活性要低得多。另一方面，4-氨基磺酰基化合物（22a-e）的盐酸化活性与之前报告的 5-氨基磺酰基化合物一样强。14b 和 22a 具有降尿酸活性。

  Substituted 5,6-dihydrofuro[3,2-f]-1,2-benzisoxazole-6-carboxylic acids: high-ceiling diuretics with uricosuric activity

  摘要：

  A series of substituted 5,6-dihydrofuro[3,2-f]-1,2-benzisoxazoles was prepared and evaluated for their saluretic and uricosuric properties. Pharmacological evaluation of the title compounds was carried out in mice, rats, dogs, and monkeys. The diuretic/saluretic nature of these compounds was observed in all species, whereas the uricosuric activity was best seen in the Cebus monkey. Evaluation of the enantiomers of 8-chloro-3-(o-fluorophenyl)-5,6-dihydrofuro [3,2-f]-1,2-benzisoxazole-6-carboxylic acid (15k) revealed that only the (+) enantiomer (29) displayed diuretic and saluretic activity, whereas both enantiomers possessed uricosuric activity. X-ray analysis showed that the (-) enantiomer (30) possesses the 2R configuration.

  2, 3-Dihydrobenzofuran derivatives having various sulfamoyl groups at the 5-position were synthesized and tested for oral diuretic and saluretic activities in rats and mice. Intraperitoneal uricosuric activity was also tested by a clearance method using oxonate-treated rats. Structureactivity relationships are presented. The 6, 7-dichloro-5-N, N-disubstituted sulfamoyl-2, 3-dihydro-benzofuran-2-carboxylic acids (9ab, ac, 13a and b) having lower alkyl substituents showed the most potent diuretic and saluretic activities among the compounds synthesized. Hyperuricosuric activity was observed in 6, 7-dichloro-2, 3-dihydrobenzofuran-2-carboxylic acids and 2-hydroxymethyl-6, 7-dichloro-2, 3-dihydrobenzofurans having a 5-sulfamoyl group, with relatively small substituents (9aa-ac, af, ak, al, an, ao and 16a-c). The saluretic activity of 9ab showed a high-ceiling profile. Examination of the enantiomers of 9ab revealed that the (-) -enantiomer is responsible for most of the diuretic and saluretic activities, while the (+) -enantiomer is responsible for most of the uricosuric activity.

  5-位含有各种磺酰胺基团的2,3-二氢苯并呋喃衍生物被合成并在大鼠和小鼠中测试了其口服利尿和促尿钠排泄活性。还通过使用草酸盐处理的大鼠的清除法测试了腹腔内促尿酸排泄活性。介绍了构效关系。具有较低烷基取代基的6,7-二氯-5-N,N-二取代磺酰胺基-2,3-二氢苯并呋喃-2-羧酸（9ab, ac, 13a和b）在合成的化合物中显示出最强的利尿和促尿钠排泄活性。在具有5-磺酰胺基团的6,7-二氯-2,3-二氢苯并呋喃-2-羧酸和2-羟甲基-6,7-二氯-2,3-二氢苯并呋喃中观察到高尿酸盐排泄活性，取代基相对较小（9aa-ac, af, ak, al, an, ao和16a-c）。9ab的促尿钠排泄活性显示出高上限特征。检查9ab的对映体发现，（-）-对映体负责大部分利尿和促尿钠排泄活性，而（+）-对映体负责大部分促尿酸排泄活性。
