Structure-activity relationships of the 1-amino-3-(1H-indol-1-yl)-3-phenylpropan-2-ol series of monoamine reuptake inhibitors

The SAR of a series of 1-amino-3-(1H-indol-1-yl)-3-phenylpropan-2-ols as monoamine reuptake inhibitors, with a goal to improve both potency toward inhibiting the norepinephrine transporter and selectivity over the serotonin transporter, is reported. The effect of specific substitution on both the 3-phenyl group and the indole moiety were explored. This study led to the discovery of compound 20 which inhibited the norepinephrine transporter with an IC50 value of 4 nM while exhibiting 86-fold selectivity over the serotonin transporter.

Chromium-Based Metal-Organic Framework MIL-101 Decorated with CdS Quantum Dots for the Photocatalytic Synthesis of Imines

Imine and its derivatives, serving as vital intermediates to construct N-containing heterocyclic compounds, are the highly desired products for fine chemical industry and pharmaceutical industry. With visible light as environmental-benign energy sources, imines are generally synthesized with coupling of amines and alcohols or oxidative self-coupling of amines. However, the coupling of amines and alcohols strategy is usually catalyzed by noble metal catalyst, and the yield of imines is still far from satisfactory owing to the formation of overhydrogenation byproducts. Meanwhile, oxidation self-coupling of amines cannot meet the requirement for the synthesis of asymmetrical substituted imines. In this work, CdS quantum dots decorated MIL-101 catalysts have been constructed as versatile catalysts for photocatalytic synthesis of imines with two different strategies at low temperature (ice bath). Strong interactions between CdS quantum dots and MIL-101 carrier are observed by Raman and UV-Vis DRS measurement results. By taking the combined advantages of CdS quantum dots and MIL-101 materials, CdS@MIL-101 multifunctional catalyst is not only feasible to the photocatalytic coupling of amines and alcohols to synthesize imines under N2 or air atmosphere but also highly active for the oxidative self-coupling of benzylamine derivatives for the synthesis of imines with air as photo-oxidant. Noteworthy, the two photocatalytic synthesis strategies provide an ultra-high selectivity for imine products.

A versatile synthesis of pyrazolo[3,4-c]isoquinoline derivatives by reaction of 4-aryl-5-aminopyrazoles with aryl/heteroaryl aldehydes: The effect of the heterocycle on the reaction pathways

The reaction of 4-(3,4-dimethoxyphenyl)-5-aminopyrazoles 7A-D with aromatic and heterocyclic aldehydes in strong acidic media (trifluoroacetic or formic acid) has been studied. The initial azomethine derivatives 8 undergo cyclization similar to the Pictet-Spengler condensation to form the intermediate 4,5-dihydroisoquinolines 9 which readily dehydrogenate giving 5-aryl(heteroaryl)-pyrazolo[3,4-c]isoquinoline derivatives 10 as the final products. Whereas for benzaldehyde and its derivatives this one-pot synthesis presents a convenient general route to 5-aryl-pyrazolo[3,4-c]isoquinolines 10, in the case of heterocyclic aldehydes the product structure varies markedly with the structure of the aldehyde used: (i) 3-pyridyl-, 3-quinolyl-, 3-thienyl-, and l,2,3-thiadiazolyl-5-carboxaldehydes give 5-heteroarylpyrazolo[3,4-c] isoquinolines; (ii) l-methylbenzimidazolyl-2-carboxaldehyde gives only intermediate azomethine 8Dh, which does not cyclize; (iii) 1-R-3- indolylcarboxaldehydes (R = H, CH3, CH2Ph) eliminate the heteroaryl fragment resulting in 5-unsubstituted pyrazolo[3,4-c]isoquinolines 11. Thienyl-2-carboxaldehyde reacts by both pathways (i) and (iii) depending on the reaction conditions. The single crystal X-ray structures for 10Dj, 10Cd and 11D provide confirmation of the different types of products formed in these reactions. Mechanisms which explain these transformations are presented. The Royal Society of Chemistry 2005.

Synthesis and structure-activity relationships of novel histamine H 1 antagonists: Indolylpiperidinyl benzoic acid derivatives

A series of indolylpiperidinyl derivatives were prepared and evaluated for their activity as histamine H1 antagonists. Structure-activity relationship studies were directed toward improving in vivo activity and pharmacokinetic profile of our first lead (1). Substitution of fluorine in position 6 on the indolyl ring led to higher in vivo activity in the inhibition of histamine-induced cutaneous vascular permeability assay but lower selectivity toward 5HT2 receptor. Extensive optimization was carried out within this series and a number of histamine H1 antagonists showing potency and long duration of action in vivo and low brain penetration or cardiotoxic potential were identified. Within this novel series, indolylpiperidines 15, 20, 48, 51 and 52 exhibited a long half-life in rat and have been selected for further preclinical evaluation.

Methylsulfonic acid adsorbed on silica gel as a solid acid for dimerization of indoles: A convenient synthesis of 2,3′-Bi(3 H -indol)-3-one oximes

A simple, convenient, and efficient approach for the synthesis of (E)-2,3′-bi(3H-indol)-3-one oxime derivatives has been developed. The methodology is based on a three-component coupling reaction of indoles and sodium nitrite using a silica-supported methylsulfonic acid as solid acid. The practical utility of this three-component coupling reaction has been demonstrated in the gram-scale dimerization of indole.
