| methyldopa | A derivative of L-tyrosine having a methyl group at the alpha-position and an additional hydroxy group at the 3-position on the phenyl ring. | alpha-methyl-L-dopa |
| metyrosine | An L-tyrosine derivative that consists of L-tyrosine bearing an additional methyl substituent at position 2.

| tirofiban | A member of the class of piperidines that is L-tyrosine in which a hydrogen attached to the amino group is replaced by a butylsulfonyl group and in which the hydrogen attached to the phenolic hydroxy group is replaced by a 4-(piperidin-4-yl)butyl group. | tirofiban |
| tyrosinamide | An amino acid amide that is L-tyrosine in which the carboxy OH group is replaced by NH2. | L-tyrosinamide |
