Synthesis of Diketohexenoic Acid Derivatives by Alkenylation of Indoles and Pyrroles with 4-Pyrones

A new synthesis of functionalized (Z)-6-hetaryl-2,4-dioxo-5-hexenoic acids based on acid-catalyzed alkenylation of indoles and pyrroles with derivatives of 5-substituted 4-pyrone-2-carboxylic acid in 37-82% yields has been developed. Coupling between isochelidonic acid and indoles followed by decarboxylation afforded biologically important (E)-6-indolyl-2,4-dioxo-5-hexenoic acids. These ring-opening reactions proceed with high regioselectivity through nucleophilic attack at the C-6 position of the pyrone ring. Reactions of ethyl 6-indolyl-2,4-dioxo-5-hexenoate with nucleophiles are useful for the production of different beta-(indolyl)vinyl-containing azaheterocycles.

Indole inhibitors of human nonpancreatic secretory phospholipase A2. 1. Indole-3-acetamides

Phospholipases (PLAs) produce rate-limiting precursors in the biosynthesis of various types of biologically active lipids involved in inflammatory processes. Increased levels of human nonpancreatic secretory phospholipase A2 (hnps-PLA2) have been detected in several pathological conditions. An inhibitor of this enzyme could have therapeutic utility. A broad screening program was carried out to identify chemical structures which could inhibit hnps-PLA2. One of the lead compounds generated by the screening program was 5-methoxy-2-methyl-1-(phenylmethyl)-1H-indole-3-acetic acid (13a). We describe the syntheses, structure-activity relationships, and pharmacological activities of a series of indole-3-acetamides and related compounds derived from this lead. This SAR was undertaken with the aid of X- ray crystal structures of complexes between the inhibitors and hnps-PLA2 which were of great value in directing the SAR.

Cs2CO3-catalyzed alkylation of indoles with trifluoromethyl ketones

A Cs2CO3-catalyzed alkylation reaction of indoles with trifluoromethyl ketones was presented. Both alicyclic and aromatic trifluoromethyl ketones as well as various substituted indoles are compatible with the methodology. Good to excellent yields of the corresponding trifluoromethyl substituted tertiary alcohols 2,2,2-tritrifluoro-1-(1H-indol-3-yl)-ethan-1-ols were acquired as the sole products.

Revisiting the beta-lactams for tuberculosis therapy with a compound-compound synthetic lethality approach

The suboptimal effectiveness of beta-lactam antibiotics against Mycobacterium tuberculosis has hindered the utility of this compound class for tuberculosis treatment. However, the results of treatment with a second-line regimen containing meropenem plus a beta-lactamase inhibitor were found to be encouraging in a case study of extensively drug-resistant tuberculosis (M. C. Payen, S. De Wit, C. Martin, R. Sergysels, et al., Int J Tuberc Lung Dis 16:558-560, 2012, https://doi.org/10.5588/ijtld.11.0414). We hypothesized that the innate resistance of M. tuberculosis to beta-lactams is mediated in part by noncanonical accessory proteins that are not considered the classic targets of beta-lactams and that small-molecule inhibitors of those accessory targets might sensitize M. tuberculosis to beta-lactams. In this study, we screened an NIH small-molecule library for the ability to sensitize M. tuberculosis to meropenem. We identified six hit compounds, belonging to either the N-arylindole or benzothiophene chemotype. Verification studies confirmed the synthetic lethality phenotype for three of the N-arylindoles and one benzothiophene derivative. The latter was demonstrated to be partially bioavailable via oral administration in mice. Structure-activity relationship studies of both structural classes identified analogs with potent antitubercular activity, alone or in combination with meropenem. Transcriptional profiling revealed that oxidoreductases, MmpL family proteins, and a 27-kDa benzoquinone methyltransferase could be the targets of the N-arylindole potentiator. In conclusion, our compound-compound synthetic lethality screening revealed novel small molecules that were capable of potentiating the action of meropenem, presumably via inhibition of the innate resistance conferred by beta-lactam accessory proteins. beta-Lactam compound-compound synthetic lethality may be an alternative approach for drug-resistant tuberculosis.

Synthesis and biological properties of aryl methyl sulfones

A novel group of aryl methyl sulfones based on nonsteroidal anti-inflammatory compounds exhibiting a methyl sulfone instead of the acetic or propionic acid group was designed, synthesized and evaluated in vitro for inhibition against the human cyclooxygenase of COX-1 and COX-2 isoenzymes and in vivo for anti-inflammatory activity using the carrageenan induced rat paw edema model in rats. Also, in vitro chemosensitivity and in vivo analgesic and intestinal side effects were determined for defining the therapeutic and safety profile. Molecular modeling assisted the design of compounds and the interpretation of the experimental results. Biological assay results showed that methyl sulfone compounds 2 and 7 were the most potent COX inhibitors of this series and best than the corresponding carboxylic acids (methyl sulfone 2: IC50 COX-1 = 0.04 and COX-2 = 0.10 muM, and naproxen: IC50 COX-1 = 11.3 and COX-2 = 3.36 muM). Interestingly, the inhibitory activity of compound 2 represents a significant improvement compared to that of the parent carboxylic compound, naproxen. Further support to the results were gained by the docking studies which suggested the ability of compound 2 and 7 to bind into COX enzyme with low binding free energies. The improvement of the activity of some sulfones compared to the carboxylic analogues would be performed through a change of the binding mode or mechanism compared to the standard binding mode displayed by ibuprofen, as disclosed by molecular modeling studies. So, this study paves the way for further attention in investigating the participation of these new compounds in the pain inhibitory mechanisms. The most promising compounds 2 and 7 possess a therapeutical profile that enables their chemical scaffolds to be utilized for development of new NSAIDs.

Indomethacin analogues that enhance doxorubicin cytotoxicity in multidrug resistant cells without cox inhibitory activity

Conformationally restricted indomethacin analogues were designed and prepared from the corresponding 2-substituted indoles, which were synthesized by a one-pot isomerization/enamide-ene metathesis as the key reaction. Conformational analysis by calculations, NMR studies, and X-ray crystallography suggested that these analogues were conformationally restricted in the s-cis or the s-trans form due to the 2-substituent as expected. Their biological activities on cyclooxygenase-1 (COX-1) inhibition, cyclooxygenase-2 (COX-2) inhibition, and modulation of MRP-1-mediated multidrug resistance (MDR) are described. Some of these indomethacin analogues enhanced doxorubicin cytotoxicity, although they do not have any COX inhibitory activity, which suggests that the MDR-modulating effect of an NSAID can be unassociated with its COX-inhibitory activity. This may be an entry into the combination chemotherapy of doxorubicin with a MDR modulator.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1076-74-0 is helpful to your research. SDS of cas: 1076-74-0

Improving the stability of photochromic fluorinated indolylfulgides

Fluorinated indolylfulgides are a class of photochromic organic compounds. It is possible to consider potential applications of these compounds in optical devices such as switches and memory. Two novel fulgides, a deuterated trifluoromethyl indolylfulgide and a trifluoromethyl dicyclopropyl indolylfulgide, were designed based on prior mechanistic studies to have greater thermal stability and potentially greater photochemical stability. The absorption spectra, thermal stabilities in both toluene and polymer films, and photochemical fatigue resistances of both fulgides were measured. The cyclizable Z-form. of the dicyclopropyl fulgide displayed a significant red shift of the absorption maximum compared to any other fulgide. Deuteration led to greater thermal stability of the fluorinated fulgide. Moreover, the Z-form of the dicyclopropyl fulgide showed excellent durability in PMMA at 80C. The solution-based study of the dicyclopropyl fulgide demonstrated only E-Z-isomerization after prolonged treatment (380 h) at 80C in toluene. In addition, the trifluoromethyl dicyclopropyl indolylfulgide is the most photochemically stable yet reported; it underwent 10,000 photochemical cycles, coloration followed by bleaching, before degrading by 13%.

Rhodium-catalyzed coupling of alpha-lactams with indole derivatives

We report herein a method that allows for the formation of a C-N bond between the C-3 carbon of alpha-lactams and the nitrogen atom of indoles. A general procedure for the coupling of indoles and alpha-lactams in only 25 min with high yield is reported. The scope of the reaction was extended by the development of a method for the in situ generation of less stable phenyl-substituted alpha-lactams. The developed method provides an atom-economical method for the formation of substituted alpha-amino amides that are found in a variety of biologically-active compounds.

The geminal dimethyl analogue of Flurbiprofen as a novel Abeta42 inhibitor and potential Alzheimer’s disease modifying agent

The subtle modification of a selection of Abeta42 inhibiting non-steroidal anti-inflammatory drugs (NSAIDs), through synthesis of the geminal dimethyl analogues, was anticipated to ablate their cyclooxygenase activity whilst maintaining Abeta42 inhibition. Methylflurbiprofen 6 exhibited similar in vitro Abeta42 inhibition to its parent NSAID Flurbiprofen and was further evaluated in the Tg2576 mouse model of Alzheimer’s disease and an animal model of gastro-intestinal (GI) impairment, but proved unviable for further clinical development.
