5-Methylcytosine is a methylated form of the DNA base cytosine (C) that regulates gene transcription and takes several other biological roles. [1] When cytosine is methylated, the DNA maintains the same sequence, but the expression of methylated genes can be altered (the study of this is part of the field of epigenetics). 5-Methylcytosine is incorporated in the nucleoside 5-methylcytidine.
5-Methyltryptamine (5-MeT, 5-Me-T) is a non-selective serotonin receptor agonist and serotonin releasing agent of the tryptamine family that has been used in scientific research.
