A series of 5-substituted 2-pyrrolidinones was synthesized through a one-pot ruthenium alkylidene-catalyzed tandem RCM/isomerization/nucleophilic addition sequence. The intermediates resulting from RCM/isomerization showed reactivity toward electrophiles in aldol condensation reactions which provided a new entry for the total synthesis of the antileukemic natural product violacein.

A crucial event in prostate cancer progression is the transition from a hormone-sensitive to a lethal castration-refractory disease state. The antagonist-to-agonist conversion due to mutation in AR is a critical problem with the current clinically used antiandrogens. We aim to identify novel antiandrogens that remain as a pure antagonist even in the mutated ARs. By synthesizing a series of ionone-based chalcones, we have identified a novel chalcone (17) that is a pan-antagonist of the wild type and the clinically relevant T877A, W741C and H874Y mutated ARs in luciferase reporter assays in PC-3 cells. Further, chalcone 17 demonstrates sub-micromolar to low micromolar antiproliferative activity in LNCaP, MDA-PCa-2b, 22Rv1 and C4-2B prostate cancer cells, all of which express mutated ARs and confer resistance to the current clinically used antiandrogens. The results suggest that chalcone 17 could be a good candidate for further pre-clinical development as a novel antiandrogen for advanced prostate cancer.

An efficient catalytic system of CuI/8-hydroxyquinalidine was developed for the coupling of aryl iodides and indole as well as some azoles. The reaction could be carried out at 90C under the condition of relatively low catalyst loading, affording various N-arylindoles and N-aryl azoles in good yields. The functionalized and hindered aryl iodides were suitable substrates for this transformation. Copyright

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C14H11N, you can also check out more blogs about16096-33-6

A series of aryl-substituted indole and indoline derivatives were discovered as novel RORgammat agonists by a scaffold-based hybridization of the reported RORgammat agonists 1 and 2. SAR studies on the core structures, the RHS hydrophilic side chains and the LHS hydrophobic aryl groups of a hybrid compound 3 led to the identification of potent RORgammat agonists with improved drug-like properties. Compound 14 represented a high potency lead with an EC50 of 20.8 ± 1.5 nM, the (S)-enantiomer (EC50 = 16.1 ± 4.5 nM) of which was 17 times more potent than the (R) counterpart (EC50 = 286 ± 30.4 nM) in RORgamma dual FRET assay. The cell-based GAL4 reporter gene assay also suggested 14 as the most active compound which exhibited an EC50 of 247 ± 33.1 nM and a maximum activation percentage of 133%. Moreover, 14 showed high metabolic stability (t1/2 = 113 min) in mouse liver microsome and had improved aqueous solubility at pH 7.4 compared to the parent compounds. Furthermore, 14 was found to be orally bioavailable and demonstrated excellent in vivo pharmacokinetics in mice. Present studies indicate that 14 deserves further investigation in tumor animal models as a potential candidate of RORgammat agonist for cancer immunotherapy.

The first total synthesis of asterredione was efficiently accomplished over five linear steps and in 21.5% overall yield. As the crucial step, the 2-quaternary 1,3-cyclopentenedione skeleton of asterredione was readily achieved using the Darzens/ring-expansion strategy developed in our laboratory. The structure of synthesized asterredione was fully confirmed by X-ray crystallography.

A time-efficient and eco-conscious microwave methodology was developed and applied to synthesize a systematic library of pentamethine cyanine dyes and their corresponding precursors. The synthesis outlined herein drastically reduced the reaction pathway for pentamethine carbocyanine dye syntheses from days to min, as well as producing increased yields (89-98%) to the conventional heating method (18-64%). Twelve examples of pentamethine cyanine dyes were synthesized by means of microwave-assisted organic synthesis which provided excellent yield in expedited reaction time and were obtained using facile isolation methods. Furthermore, three cyanines were prepared with a novel methylene dioxy heterocyclic structure which imparted an approximately 40 nm bathochromic shift compared to unsubstituted counterparts; these results were shown to be in agreement with DFT calculations and HOMO-LUMO energy differences.

During the last 35 years of studies of Azospirillum-plant interaction, over 20 proposals were suggested for the mechanism of action by which Azospirillum spp., the most intensively studied plant growth-promoting bacteria, enhances plant growth. The proposals include a single phytohormone activity, multiple phytohormones, nitrogen fixation, assortments of small-sized molecules and enzymes, enhanced membrane activity, proliferation of the root system, enhanced water and mineral uptake, mobilization of minerals, mitigation of environmental stressors of plants, and direct and indirect biological control of numerous phytopathogens. By volume, the largest number of published information involves hormonal activities, nitrogen fixation, and root proliferation. After analyzing the accumulated knowledge, it was concluded that this versatile genus possesses a large array of potential mechanisms by which it can effect plant growth. Consequently, this review proposes the “Multiple Mechanisms Theory,” based on the assumption that there is no single mechanism involved in promotion of plant growth by Azospirillum, but a combination of a few or many mechanisms in each case of inoculation. These may vary according to the plant species, the Azospirillum strain, and environmental conditions when the interaction occurred. The effect can be cumulative, an “additive hypothesis” (proposed before), where the effects of small mechanisms operating at the same time or consecutively create a larger final effect on plant. Additionally, the observed effect on plant growth can be the result of a tandem or a cascade of mechanisms in which one mechanism stimulates another, yielding enhanced plant growth, such as the plausible relations among phytohormones, nitric oxide, membrane activities, and proliferation of roots. Finally, the growth promotion can also be a combination of unrelated mechanisms that operate under environmental or agricultural conditions needed by the crop at particular locations, such as mitigating stress (salt, drought, toxic compounds, adverse environment), and the need for biological control of or reducing pathogenic microflora.
