31. Some monoterpenoid indole alkaloids also interact with adrenoceptors. 32. Step-wise mechanism of the Fukuyama Indole Synthesis starting with the alkenylthioanilide substituent. 33. This has been achieved with catalytic systems utilizing Br�nsted acids to activate the indole . 34. Indole is absorbed into the blood by the intestine and passes to the liver.35. There, indole is converted to indoxyl sulfate. 36. It is the precursor to indole -3-acetic acid and synthetic tryptophan. 37. It is the indole 2-ethyl derivative of related compound JWH-018. 38. La segunda razon es de indole monetaria. 39. Alternatively the compound has been synthesized by Fischer indole synthesis using Glutamic acid and Phenylhydrazine. 40. There are also a variety of other reactions that result in the same indole skeleton.
