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.

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.

A transition-metal-free protocol for the redox-neutral light-induced decarboxylative coupling of carboxylic acids with (hetero)aromatic nitriles at ambient temperature is presented. A broad scope of acids and nitriles is accepted, and alcohols can be coupled in a similar fashion through their oxalate half esters. Various inexpensive sources of UV light and even sunlight can be used to achieve this C-C bond formation proceeding through a free radical mechanism.

The reaction of cotarnine and acyl/aryl ketones in ?green? solvents provides an efficient approach to an array of privileged 1,2,3,4-tetrahydroisoquinolines in excellent yields by metal-free activation of C(sp3)?H bonds. This one-pot procedure takes place under base-free conditions at room temperature, and tolerates a wide range of functionalities. The reaction is highly chemoselective, can be performed on a multi-gram scale, and pure products are isolated by simple filtration without workup. Interestingly, the complementary two-step procedure from cotarnine halide salts gives the Mannich products in good yields. The scope was elaborated to 9-bromocotarnine salts to access a range of 9-bromonoscapine-derived analogues. The methodology has been developed considering the structural similarity of cotarnine derivatives to noscapinoids, which represent an emerging class of microtubule-modulating anticancer agents.
