Applications & Uses
Uses
Indole is used in perfumery and in preparing tryptophan, one of the 20 amino acids commonly found in animal proteins. It has important application in the industry of plant growth. It is used to prepare indoleacetic acid (auxin) and other plant growth substances which help the development of roots in plant. Indole and its derivatives are widely used in making perfumes, dyes, agrochemicals and medicines.
Uses
Reactant for preparation of:Inhibitors of NOD1-Induced Nuclear Factor-κB ActivationSphingosine-1-phosphate 4(S1P4) receptor antagonistsCytotoxic cell cycle inhibitors2-AminopyridinesPET agent for imaging of protein kinase C (PKC)Sodium-dependent glucose co-transporter 2 (SGLT2) inhibitors for the management of hyperglycemia in diabetesα4β2-Nicotinic acetylcholine receptor-selective partial agonistsmGlu4 positive allosteric modulatorsBacterial biofilm inhibitorsSerotonin 5-HT6 receptor antagonists
Uses
As an indole derivative, Indoline can be used in the preparation of various medicinal compounds such as potential α1-adrenoceptor (α1-AR) antagonists.
