Based on 2 publication(s) in Google Scholar
Tryptophol is an aromatic alcohol and secondary metabolite produced by microorganisms. Tryptophol induces apoptosis and cleavage of caspase-8. Tryptophol inhibits Cunninghamella blakesleeana biofilm. Tryptophol has anti-phage infection, biofilm formation regulation, anti-inflammatory, hemolytic, sleep induction, temperature change, seizure susceptibility and immune regulation activities. Tryptophol is used in the research of African trypanosomiasis, sleep disorders, epilepsy.
