  skatole
5-Aza analogs were prepared of several tryptamine derivatives and a skatole derivative known to bind at human 5-HT6 receptors and evaluated to determine if they bind in a manner similar to their indolic analogs.
      
For example, N1-(4-aminobenzenesulfonyl)-5-azaskatole (18; Ki = 41 nM) displayed an affinity comparable to N1-(4-aminobenzenesulfonyl)skatole.

An in vitro study was conducted to investigate the formation of indole and 3 methylindole(skatole) by a mixed bacterial populations from the large intestine of pigs and to study the effects of pH on the relative production of indole and skatole. Pig fecal slurries converted added L tryptophan either to indole without detectable intermediate or to 3 methylindole(skatole) via indole 3 acetate. The pH had dramatic effects on the relative production of skatole and indole. At pH 6.5,42% of the L tryptophan...

An in vitro study was conducted to investigate the formation of indole and 3 methylindole(skatole) by a mixed bacterial populations from the large intestine of pigs and to study the effects of pH on the relative production of indole and skatole. Pig fecal slurries converted added L tryptophan either to indole without detectable intermediate or to 3 methylindole(skatole) via indole 3 acetate. The pH had dramatic effects on the relative production of skatole and indole. At pH 6.5,42% of the L tryptophan was converted to skatole and 58% was converted to indole after 24 h of incubation. At pH8.0, 78% of the added L tryptophan was converted to skatole and 22% was converted to indole. While at pH 5.0, only 16% of the added L tryptophan was converted to skatole and 84% was converted to indole. Our results show that the relative amounts of the two end products can be altered by changing the environmental conditions. High pH values favor the production of skatole, while low pH values favor the production of indole.

本试验研究了猪粪便菌群作用下粪臭素 (3 甲基吲哚 )和吲哚的形成途径以及pH对色氨酸降解成粪臭素和吲哚相对产量的影响。试验结果表明 ,在猪大肠菌群作用下L 色氨酸既能直接降解形成吲哚 ,又能经吲哚 3 乙酸再形成粪臭素。pH对色氨酸降解成粪臭素和吲哚相对产量有明显影响。pH =6 .5时 ,约 4 2 %色氨酸转化为粪臭素 ,5 8%色氨酸转化为吲哚 ;pH =8.0时 ,约 78%色氨酸转化粪自素 ,2 2 %氨酸转化为吲哚 ;pH =5 .0时 ,只有 16 %色氨酸转化为粪臭素 ,而 84 %色氨酸转化为为吲哚。本试验结果提示 ,通过改变环境的pH可以使色氨酸降解成粪臭素和吲哚相对产量发生变化 ,高pH环境有利于粪臭素的产生 ,而低pH环境有利于吲哚的产生。

methylindole is one of protein metabolizable product which was acted by anaerobic microorganism in largeintestine. It causes negative influence on pork. The main results showed as follows: During 0-120ng/ml, the linearity ofstandard curve was well. The rate of recovery was about 97% , relative error was under 3%. The sensitivity and accuracy ofthis method were well.

3-甲基吲哚即粪臭素,是小肠中未消化的蛋白质在大肠厌氧微生物作用下的产物之一,对未阉割的公猪肉品质有显著的负面影响。本次实验就对猪肉背膘中3-甲基吲哚的测定方法进行了研究。结果为:标样浓度在120ng/ml范围内线性良好,回收率在97%左右,样品相对偏差在3%以下。表明该方法的灵敏度和准确度均较好。
