2:2 Complexes from Diphenylpyridiniums and Cucurbit[8]uril: Encapsulation-Promoted Dimerization of Electrostatically Repulsing Pyridiniums

Rigid linear compounds G1 and G2, which contained two 4-phenylpyridinium (PhPy+) units, have been prepared to investigate their binding with cucurbit[8]uril (CB[8]). X-ray crystallographic structures revealed that in the solid state both compounds were included by CB[8], through antiparallel stacking, to form 2:2 quaternary complexes (G1)2@(CB[8])2 and (G2)2@(CB[8])2. For the former complex, CB[8] entrapped G1 by holding two heterodimers of its Py+ and benzyl units, which were at opposite ends of the backbone. In contrast, for the first time, the second complex disclosed parallel stacking of two cationic Py+ units of G2 in the cavity of CB[8] in the solid state, despite the generation of important electrostatic repulsion. Isothermal titrations in water afforded high apparent association constants of 4.36¡Á106 and 6.43¡Á106 m?1 for 1:1 complexes G1@CB[8] and G2@CB[8], respectively, and 1H NMR spectroscopy experiments in D2O confirmed a similar stacking pattern to that observed in the solid state. A previous study and crystal structures of the 2:1 complexes formed between three new controls, G3?5, and CB[8] did not display such unusual stacking of the cationic Py+ unit; this may be attributed to the multivalency of the two CB[8] encapsulation interactions.

Total Synthesis of Tetrahydroisoquinoline-Based Bioactive Natural Products Laudanosine, Romneine, Glaucine, Dicentrine, and Their Unnatural Analogues Isolaudanosine and Isoromneine

Starting from suitably substituted homophthalic acids, total synthesis of titled alkaloids have been demonstrated in very good yields. The obtained natural products laudanosine and romneine were utilized to accomplish synthesis of two isoquinoline-based alkaloids glaucine and dicentrine. Base-induced selective generation of two different types of benzylic carbanions, their coupling reactions with 3,4-dimethoxybenzyl mesylate, and the regioselective iodination followed by intramolecular aryl-aryl coupling reactions to form the fused biaryl systems were the strategic steps.

Cholinergic effects of molecular segments of apomorphine and dopaminergic effects of N,N dialkylated dopamines

The hydrochlorides of molecular segments of apomorphine [2 (3′,4′ dihydroxybenzyl) 1,2,3,4 tetrahydroisoquinoline, 2 (3′,4′ dihydroxybenzyl) piperidine, and 1,2,3,4 tetrahydroisoquinoline with their respective N methyl and N n propyl homologs] and N,N dialkylated dopamine compounds were synthesized and studied for LD50 in intact mice; stereotypy in intact mice; curving of the body in unilaterally caudectomized mice; rotation in 6 hydroxydopamine lesioned rats, and activation of adenylate cyclase in homogenates of mouse caudate nuclei. Instead of dopaminergic effects 1 (3′,4′ dihydroxybenzyl) 2 methyl 1,2,3,4, tetrahydroisoquinoline and 2 methyl 1,2,3,4, tetrahydroisoquinoline showed cholinergic ones. These effects were blocked in atropine pretreated animals. Of the N,N dialkylated dopamine compounds synthesized, the N n propyl N n butyldopamine ranked in all tests as the strongest dopamine receptor agonist and N methyl N n propyldopamine as the weakest. In contrast, N,N dimethyldopamine and 1 (3,4 dihydroxyphenylethyl) piperidine showed no dopaminergic effects. The effectiveness of the dopaminergic agonists depended on the length of the N alkyl substituents suggesting interactions with hydrophobic regions of the receptor site.

Base-Dependent Divergent Annulation of 4-Chloro-3-formylcoumarin and Tetrahydroisoquinoline: Application to the Synthesis of Isolamellarins and Hydroxypyrrolones

A series of pyrrolo[2,1-a]isoquinoline and coumarin-fused pentacyclic derivatives were synthesized via base-mediated divergent annulation of 4-chloro-3-formylcoumarin and tetrahydroisoquinoline as a key step. This method was then extended to the preparation of isolamellarins A and B (isolamellarin G trimethyl ether). When exposed to UV light, the pyrrolo[2,1-a]isoquinoline- and coumarin-fused pentacycles B were found to undergo aerobic oxidation to give the corresponding hydroxypyrrolones.

The influence of substitution at aromatic part of 1,2,3,4-tetrahydroisoquinoline on in vitro and in vivo 5-HT1A/5-HT2A receptor activities of its 1-adamantoyloaminoalkyl derivatives

Further structure-activity relationship (SAR) studies with the 1,2,3,4-tetrahydroisoquinoline (THIQ) class of 5-HT1A ligands led to the synthesis of new 1-adamantoyloaminoalkyl derivatives. The impact of substituent variations in the aromatic part of THIQ moiety on 5-HT1A and 5-HT2A receptor affinities, as well as in vivo functional properties of the investigated compounds were discussed. It was found that modification reduced the binding affinity for 5-HT1A receptors (in comparison with unsubstituted THIQ derivatives); however, the majority of new compounds still remained potent 5-HT1A ligands (Ki = 4.9-46 nM) and most of them showed features of partial agonists of postsynaptic 5-HT1A receptors. At the same time, their 5-HT2A receptor affinity was slightly increased (Ki = 40-1475 nM), which resulted in a loss of 5-HT2A/5-HT1A selectivity. 5-Br,8-OCH3 derivative – the most potent, mixed 5-HT1A/5-HT2A ligand – produced activation of presynaptic 5-HT1A receptors and showed properties of a 5-HT2A receptor antagonist.
