Improved simplicity and practicability in copper-catalyzed alkynylation of tetrahydroisoquinoline

Abstract: Alkynylation reactions of N-protected tetrahydroisoquinolines have been performed using several different protocols of cross dehydrogenative coupling. Initially, a CuCl-catalyzed method was investigated, which worked well with three different N-protecting groups, namely phenyl, PMP, and benzyl and t-BuOOH as oxidant in acetonitrile as solvent. The peroxide could then be replaced by simple air and acetonitrile for water, leading to an overall very environmentally friendly protocol. Finally, a decarboxylative alkynylation protocol starting from alkynoic acids was also developed using again air as oxidant. This avoids the use of gaseous alkynes in the introduction of short-chained alkyne substituents. Graphical abstract: [Figure not available: see fulltext.]

N-terminal guanidinylation of TIPP (Tyr-Tic-Phe-Phe) peptides results in major changes of the opioid activity profile

Derivatives of peptides of the TIPP (Tyr-Tic-Phe-Phe; Tic = 1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid) family containing a guanidino (Guan) function in place of the N-terminal amino group were synthesized in an effort to improve their blood-brain barrier permeability. Unexpectedly, N-terminal amidination significantly altered the in vitro opioid activity profiles. Guan-analogues of TIPP-related delta opioid antagonists showed delta partial agonist or mixed delta partial agonist/mu partial agonist activity. Guanidinylation of the mixed mu agonist/delta antagonists H-Dmt-Tic-Phe-Phe-NH2 (DIPP-NH2) and H-Dmt- TicPsi[CH2NH]Phe-Phe-NH2 (DIPP-NH2[Psi]) converted them to mixed mu agonist/delta agonists. A docking study revealed distinct positioning of DIPP-NH2 and Guan-DIPP-NH2 in the delta receptor binding site. Lys3-analogues of DIPP-NH2 and DIPP-NH2[Psi] (guanidinylated or non-guanidinylated) turned out to be mixed mu/kappa agonists with delta antagonist-, delta partial agonist- or delta full agonist activity. Compounds with some of the observed mixed opioid activity profiles have therapeutic potential as analgesics with reduced side effects or for treatment of cocaine addiction.

Visible-Light-Promoted C(sp3)-C(sp2) Cross-Dehydrogenative Coupling of Tertiary Amine with Imidazopyridine

A metal-free visible-light-promoted C(sp3)-C(sp2) cross-dehydrogenative coupling between tetrahydroisoquinoline and imidazo[1,2-a]pyridine has been developed to afford 3-substituted imidazopyridines using a catalytic amount of rose bengal as photosensitizer under aerobic conditions. The present methodology is also applicable to imidazo[1,2-a]pyrimidine, indolizine, indole, and pyrrole as well as N,N-dimethyl aniline. Wide substrates scope, use of organo photocatalyst, metal-free, and mild reaction conditions are the attractive features of this methodology.

Exploring the active site of phenylethanolamine N-methyltransferase with 1,2,3,4-tetrahydrobenz[h]isoquinoline inhibitors

1,2,3,4-Tetrahydrobenz[h]isoquinoline (THBQ, 11) is a potent, inhibitor of phenylethanolamine N-methyltransferase (PNMT). Docking studies indicated that the enhanced PNMT inhibitory potency of 11 (hPNMT Ki = 0.49 muM) versus 1,2,3,4-tetrahydroisoquinoline (5, hPNMT Ki = 5.8 muM) was likely due to hydrophobic interactions with Val53, Met258, Val272, and Val269 in the PNMT active site. These studies also suggested that the addition of substituents to the 7-position of 11 that are capable of forming hydrogen bonds to the enzyme could lead to compounds (14-18) having enhanced PNMT inhibitory potency. However, these compounds are in fact less potent at PNMT than 11. Furthermore, 7-bromo-THBQ (19, hPNMT Ki = 0.22 mM), which has a lipophilic 7-substituent that cannot hydrogen bond to the enzyme, is twice as potent at PNMT than 11. This once again illustrates the limitations of docking studies for lead optimization.

Synthesis, biological evaluation, X-ray molecular structure and molecular docking studies of RGD mimetics containing 6-amino-2,3-dihydroisoindolin-1-one fragment as ligands of integrin alphaiIbbeta3

A series of novel RGD mimetics containing phthalimidine fragment was designed and synthesized. Their antiaggregative activity determined by Born’s method was shown to be due to inhibition of fibrinogen binding to alphaIIbbeta3. Molecular docking of RGD mimetics to alphaIIbbeta3 receptor showed the key interactions in this complex, and also some correlations have been observed between values of biological activity and docking scores. The single crystal X-ray data were obtained for five mimetics.
