Bioorganic & medicinal chemistry letters, 15(14), 3430-3433 (2005-06-14)
The discovery of 1-amino-1,2,3,4-tetrahydronaphthalene-2-carboxylic acid analogs as potent human melanocortin-4 selective agonists is described.

Biopolymers, 34(9), 1213-1219 (1994-09-01)
A molecular mechanics study (grid search and energy minimization) of the highly delta receptor-selective delta opioid antagonist H-Tyr-Tic-Phe-OH (TIP; Tic: tetrahydroisoquinoline-3-carboxylic acid) resulted in four low energy conformers with energies within 2 kcal/mol of that of the lowest energy structure.

We have investigated the effects of mono-substitutions with the conformationally restricted amino acid, 1,2,3,4 tetrahydroisoquinoline-3-carboxylic acid (Tic) at position 3 in arginine vasopressin (AVP), at positions 2, 3 and 7 in potent non-selective cyclic AVP V2/V1a antagonists, in potent and

Tic, short for 1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid, is a kind of unnatural α-amino acids. Due to its distinct geometrical conformation and biological activity, the structure of Tic, regarded as the surrogate of proline and the rigid analogue of phenylalanine or tyrosine, has
P Majer et al.
International journal of peptide and protein research, 43(1), 62-68 (1994-01-01)
A new method of synthesizing ortho-methylated phenylalanines has been developed. Phenylalanines with at least one free ortho-position undergo a Pictet-Spengler cyclization with formaldehyde followed by hydrogenolytic splitting of the endocyclic benzylic C--N bond of 1,2,3,4-tetrahydroisoquinolines and afford corresponding ortho-methyl derivatives.
