Indole ring-amino acids
Among the 20 natural amino acids, the amino acid containing indole ring is tryptophan (Trp, W), also known as tryptophan β- Indolyl alanine is one of the essential amino acids for human body. Tryptophan can participate in the renewal of plasma proteins in animals, promote the role of riboflavin, contribute to the synthesis of nicotinic acid and heme, significantly increase the antibodies in fetuses of pregnant animals, and promote the lactation of dairy cows and sows during lactation. When livestock and poultry lack tryptophan, growth stagnates, body weight decreases, fat accumulation decreases, and testicles of breeding males shrink. It is used in medicine as a preventive and therapeutic agent for leprosy. Tryptophan is an important precursor of auxin biosynthesis in plants. Its structure is similar to IAA and widely exists in higher plants. The protective form often used in the solid-phase synthesis of our polypeptide Fmoc is Fmoc- Trp (Boc) - OH.
In order to expand the application of tryptophan in pharmaceutical research, we have made many modifications on the benzene ring of indole ring, thus forming a huge family. According to the different positions of indole rings, we mainly divide them into four categories: 4 -, 5 -, 6 - and 7 -.
