Two series of 2-butyl-8-azaspiro[5,4]decane-7,9-dione (a) and N-phthalimidobutyl (b) derivatives of 1,2,3,4-tetrahydroisoquinoline (THIQ) were synthesized. The impact of substituent variations in the aromatic part of the THIQ moiety on 5-HT1A and 5-HT2A receptor affinities, as well as in vivo functional properties of the investigated compounds are discussed. It was found that those modifications improved 5-HT2A receptor affinity, but also slightly reduced the binding affinity for 5-HT1A receptors (in comparison with the unsubstituted THIQ derivatives 3a and 3b). The most active compound (8-Br,5-OCH3-THIQ – 8a) showed features of a 5-HT1A (postsynaptic)/5-HT2A receptor antagonist. Additionally, all chloro derivatives with high and equal affinity for 5-HT1A receptors revealed different functional properties, i.e. an agonistic activity of presynaptic 5-HT1A receptors (4a) and a partial agonistic activity of postsynaptic 5-HT1A receptors (4a, 6a) or an antagonistic activity of postsynaptic ones (5a).

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Computed Properties of C9H10ClN, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 82771-60-6, in my other articles.

(Figure presented) 1-Aryltetrahydroisoquinolines (1-arylTHIQs) are important structural motifs in many alkaloids and biologically active compounds. Ligand 2a promotes the enantioselective addition of arylzinc reagents to 3,4-dihydroisoquinoline N-oxide to yield (S)-1-arylTHIQs in 97-99% ee. Pinacol arylboronic esters are the optimal precursors for the arylzinc reagents. This method is applied to the enantioselective synthesis of Solifenacin.

Heat shock protein 90 (Hsp90) is an attractive chemotherapeutic target for antitumor drug development. Herein, we reported the design and synthesis of two series of novel N-(5-chloro-2,4-dihydroxybenzoyl)-1,2,3,4-tetrahydroisoquinoline-3-carboxamides as Hsp90 inhibitors using (S)-Tic (1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid) (A1-13) and (R)-Tic (B1-13) as scaffold, respectively. Cellular thermal shift assay (CETSA) screening showed that compounds B1-13 with (R)-Tic scaffold exhibited potent ability to stabilize Hsp90alpha. Compound B7 showed not only the most potent ability to induce thermal stabilization of Hsp90alpha but also the strongest cytotoxicity. The IC50 values of B7 were 0.98 muM and 1.74 muM against the proliferation of human breast cancer MDA-MB-231 and human cervical cancer HeLa cell lines, respectively. Moreover, CETSA melt and ITDRFCETSA (isothermal dose-response fingerprint) curves confirmed that B7 bound to Hsp90alpha in 293T cells. Western blotting results indicated that B7 induced the degradation of Hsp90 clients CDK4, Her2, Cdc-2 and C-raf. In addition, docking and Molecular dynamics (MD) refinement of the B7-Hsp90 complex showed that the binding model of B7 to Hsp90 was similar with that of 8-benzyladenines. The overall properties warrant compound B7 a promising lead for the development of Hsp90 inhibitor antitumor drugs.

In the course of continuing efforts to develop potent and bladder-selective muscarinic M3 receptor antagonists, quinuclidin-3-yl 1-aryl-1,2,3,4-tetrahydroisoquinoline-2-carboxylate derivatives and related compounds were designed as conformationally restricted analogues of quinuclidin-3-yl benzhydrylcarbamate (8). Binding assays with rat muscarinic receptor subtypes revealed that the quinuclidin-3-yl 1-aryl-1,2,3,4- tetrahydroisoquinoline-2-carboxylate derivatives showed high affinities for the M3 receptor, and selectivity for the M3 receptor over the M2 receptor. Of these derivatives, (+)-(1S,3’R)-quinuclidin-3′-yl 1-phenyl-l,2,3,4-tetrahydroisoquinoline-2-carboxylate monohydrochloride (9b) exhibited almost the same inhibitory activity against bladder contraction to that of oxybutynin (1), and more than 10-fold selectivity for bladder contraction versus salivary secretion, demonstrating that 9b may be useful for the treatment of symptoms associated with overactive bladder without having side effects such as dry mouth.

To combat the emergence of drug-resistance in tumors novel strategies are urgently needed. With this in mind we designed a novel class of thiosemicarbazones able to target simultaneously sigma2 receptors and P-glycoprotein efflux pump while chelating metals such as iron. The combined effect of these targets would lead to the activation of multiple pathways to which resistant tumors are sensitive. Indeed, most of the novel thiosemicarbazones displayed antiproliferative activity in both parent (MCF7 breast adenocarcinoma and A549 lung carcinoma) and corresponding doxorubicin-resistant cells (MCF7dx and A549dx). A few compounds emerged for their potent antiproliferative activity or for their more potent effect in doxorubicin-resistant cells than in the parent ones, while other compounds emerged for their remarkable P-gp modulatory activity. These results pave the way for further studies on these targets in the oncology field, while the availability of promising molecules for resistant tumors treatment that warrant deeper investigations was increased.
