Investigation on the one-step preparation of 2-substituted benzo[B]thiophenes

A convenient and efficient synthesis of 2-substituted benzo[b]thiophenes is described. This one-step reaction of alkylthiobenzaldehyde and activated electrophiles proceeded smoothly in toluene at 120 C with magnesium oxide as a catalyst. The target 2-substituted benzo[b]thiophenes are obtained in moderate yields and the side reaction is inhibited via azeotropic distillation. According to the experiments, a plausible mechanism is presented.

Structure-Activity Relationship Study of Heterocyclic Phenylethenyl and Pyridinylethenyl Derivatives as Tau-Imaging Agents That Selectively Detect Neurofibrillary Tangles in Alzheimers Disease Brains

In order to explore novel tau-imaging agents that can selectively detect neurofibrillary tangles in Alzheimers disease (AD) brains, we designed and synthesized a series of heterocyclic phenylethenyl and (3-pyridinyl)ethenyl derivatives with or without a dimethyl amino group. In in vitro autoradiography using AD brain sections, all radioiodinated ligands with a dimethyl amino group bound to Abeta deposits in the sections. In contrast, the ligands without a dimethyl amino group showed different patterns of radioactivity accumulation in the sections depending on the kind of heterocycle contained in their molecules. Particularly, a phenylethenyl benzimidazole derivative ([125I]64) showed marked radioactivity accumulation in the temporal lobe which corresponded with the distribution of tau deposits. [125I]64 also showed the most favorable pharmacokinetics in normal mouse brains (3.69 and 0.06% ID/g at 2 and 60 min postinjection, respectively) among all ligands in this study. Taken together, these results suggest that [123I]64 may be a new candidate tau-imaging agent.

Discovery of Novel Allosteric Inhibitors of Deoxyhypusine Synthase

Deoxyhypusine synthase (DHPS) utilizes spermidine and NAD as cofactors to incorporate a hypusine modification into the eukaryotic translation initiation factor 5A (eIF5A). Hypusine is essential for eIF5A activation, which, in turn, plays a key role in regulating protein translation of selected mRNA that are associated with the synthesis of oncoproteins, thereby enhancing tumor cell proliferation. Therefore, inhibition of DHPS is a promising therapeutic option for the treatment of cancer. To discover novel lead compounds that target DHPS, we conducted synthetic studies with a hit obtained via high-throughput screening. Optimization of the ring structures of the amide compound (2) led to bromobenzothiophene (11g) with potent inhibitory activity against DHPS. X-ray crystallographic analysis of 11g complexed with DHPS revealed a dramatic conformational change in DHPS, which suggests the presence of a novel allosteric site. These findings provide the basis for the development of novel therapy distinct from spermidine mimetic inhibitors.

[1]Benzothieno[3,2-d]pyrimidine derivatives as ligands for the serotonergic 5-HT7 receptor

The present paper describes the synthesis and the binding properties for the serotonergic 5-HT7 and 5-HT1A receptors of three new series (A?C) of (benzo)thienopyrimidinone derivatives. All series exhibit a basic moiety at the 2-position of the heterocyclic scaffold such as N,N-dialkylaminoalkylthio chain in series A and phenylpiperazine, benzylpiperazine, or benzylpiperidine alkyl chain in series B and C. Compounds endowed with the best binding properties at 5-HT7R belong to the B and C types. In particular, derivatives B2 and C1 (RSC4) exhibit notable affinity for 5-HT7R (Ki = 9.08 and 0.85 nM, respectively) and selectivity over the 5-HT1AR (254- and 48-fold, respectively). The structure-affinity relationships for these three new classes of 5-HT7R ligands are discussed and, in order to rationalize and deeply investigate the observed results, molecular modeling studies were performed. In particular, the binding poses of the synthesized compounds were studied by docking them in the two receptor proteins suitably built by homology modeling. The calculated binding energies resulted in an excellent agreement with the experimental measured Ki, further validating the quality of the models.

Spectroscopic Studies of the Chan-Lam Amination: A Mechanism-Inspired Solution to Boronic Ester Reactivity

We report an investigation of the Chan-Lam amination reaction. A combination of spectroscopy, computational modeling, and crystallography has identified the structures of key intermediates and allowed a complete mechanistic description to be presented, including off-cycle inhibitory processes, the source of amine and organoboron reactivity issues, and the origin of competing oxidation/protodeboronation side reactions. Identification of key mechanistic events has allowed the development of a simple solution to these issues: manipulating Cu(I) ? Cu(II) oxidation and exploiting three synergistic roles of boric acid has allowed the development of a general catalytic Chan-Lam amination, overcoming long-standing and unsolved amine and organoboron limitations of this valuable transformation.

Benzoyl and cinnamoyl nitrogen mustard derivatives of benzoheterocyclic analogues of the tallimustine: Synthesis and antitumour activity

A series of benzoyl and cinnamoyl nitrogen mustards tethered to different benzoheterocycles and to oligopyrroles structurally related to netropsin consisting of two pyrrole-amide units and terminating with an amidine moiety have been synthesised and a structure-activity relationship determined. Derivatives 3-10 have been evaluated for their sequence selective alkylating properties and cytotoxicity against human K562 leukaemia cells. They are 2- to 50-fold less cytotoxic than tallimustine, with compound 8 being the most potent member of this series. Among tallimustine isosters, the compounds with an indole 3 or benzothiophene 6 are 4-fold less cytotoxic than tallimustine, while the compounds with an N-methyl indole or benzofuran showed a 7- and 14-fold reduced cytotoxic potency, respectively. Our preliminary results indicate that these derivatives preferentially bind to AT-rich sequence with a sequence selectivity similar to tallimustine.

Assessment of solution-phase positional scanning libraries based on distamycin A for the discovery of new DNA binding agents

The solution-phase synthesis of two 1000-membered positional scanning libraries of distamycin A analogues is described enlisting acid/base liquid-liquid extractions for isolation and purification of all intermediates and final products. The results of their screening for functional activity (L1210 cytotoxic potency) and DNA binding affinity were compared with those derived from libraries containing the same compound members but prepared in a smaller 10-compound mixture format. The positional scanning libraries, which are substantially less demanding to prepare, allowed the accurate detection of the global observations and the clearly more potent activities, but more subtle discoveries and less distinguishable activities were not detected. This is a natural consequence of testing the larger 100-compound mixtures and the relative insensitivity of the assays to the contribution of any single, uniquely acting compound in the mixture. Thus, the disadvantages associated with the loss of some information contained within the library must be balanced against the advantages of the ease of library synthesis and judged in light of the library screening objectives.
