Novel 1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid derivatives were synthesized and (S)-7-(2-{2-[(E)-2-cyclopentylvinyl]-5-methyloxazol-4-yl}ethoxy)-2-[(2E,4E)-hexadienoyl]-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid (14c) was identified as a peroxisome proliferator-activated receptor (PPAR) α/γ dual agonist. The transactivation activity of 14c was comparable to that of rosiglitazone in human PPARγ (EC50=0.14 µM) and was much

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.

2-Acyl-tetrahydroisoquinoline-3-carboxylic acid derivatives were synthesized and biologically evaluated. (S)-2-(2,4-Hexadienoyl)-7-[2-(5-methyl-2-phenyloxazol-4-yl)ethoxy]-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid (14) showed peroxisome proliferator-activated receptor γ (PPARγ) and PPARα agonist activities and protein-tyrosine phosphatase 1B (PTP-1B) inhibitory activities. PPARγ agonist activity of 14 was comparable to that of rosiglitazone, and

Incorporation of L- or D-Tic into position 7 of oxytocin (OT) and its deamino analogue ([Mpa(1)]OT) resulted in four analogues, [L-Tic(7)]OT (1), [D-Tic(7)]OT (2), [Mpa(1),L-Tic(7)]OT (3) and [Mpa(1),D-Tic(7)]OT (4). Their biological properties were described by Fragiadaki et al. (Eur J

Three Tic-containing (Tic = 1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid) model peptides were synthesized to assess the tendency of this constrained Phe analogue to fold into a beta-bend and a helical structure, and to adopt a preferred side-chain disposition. The results of the solution
