Cu(I)-phosphine complex: An efficient catalyst for synthesis of 3-indole derivatives through one-pot MCR under mild conditions

An efficient copper (I) halotriphenylphosphine catalyzed one-pot multicomponent reaction (MCR) of 3-substituted indole derivatives has been developed using a variety of aldehydes (aromatic, aliphatic, and heteroaromatic), indole, and active methylene substrates such as malononitrile and ethyl 2-cyano acetate. This reaction proceeds smoothly and obtained good to excellent yields (68-93%) using water as green solvent under ambient conditions. The obtained products were confirmed by H-1, C-13 NMR, and mass spectroscopy techniques. The one-pot MCR occurs through formation of Knoevenagel adducts then followed by Michael addition of indole.

Oxidative Conversion of Sulfonyl Indoles into 3-Alkylidene-2-oxindoles under Flow Chemical Conditions

Sulfonyl indoles were converted into 3-alkylidene-2-oxindoles using NCS as the sole reagent under flow chemical conditions. The conjugated oxindole derivatives were generally obtained as E stereoisomers in moderate to satisfactory yields. The transformation entails the oxidation of the indole ring by NCS followed by elimination of arylsulfinic acid in order to install the exocyclic unsaturation.

Expanding the Diversity of Plant Monoterpenoid Indole Alkaloids Employing Human Cytochrome P450 3A4

Human drug-metabolizing cytochrome P450 monooxygenases (CYPs) have enormous substrate promiscuity; this makes them promising tools for the expansion of natural product diversity. Here, we used CYP3A4 for the targeted diversification of a plant biosynthetic route leading to monoterpenoid indole alkaloids. In silico, in vitro and in planta studies proved that CYP3A4 was able to convert the indole alkaloid vinorine into vomilenine, the former being one of the central intermediates in the ajmaline pathway in the medicinal plant Rauvolfia serpentina (L.) Benth. ex Kurz. However, to a much larger extent, the investigated conversion yielded vinorine (19R,20R)-epoxide, a new metabolite with an epoxide functional group that is rare for indole alkaloids. The described work represents a successful example of combinatorial biosynthesis towards an increase in biodiversity of natural metabolites. Moreover, characterisation of the products of the in vitro and in planta transformation of potential pharmaceuticals with human CYPs might be indicative of the route of their conversion in the human organism.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 611-20-1, in my other articles.

Indole alkaloids: 2012 until now, highlighting the new chemical structures and biological activities

Indole alkaloids have attracted attention because of their therapeutic properties, being anti-inflammatory, antinociceptive, antitumoural, antioxidant and antimicrobial. These compounds present a wide structural diversity, which is directly related to the genera of the producing plants, as well as the biological activities. Indole alkaloids have attracted attention over the last decade because of this combination of bioactivity and structural diversity. Therefore, this review presented recent (2012-2018) advances in alkaloids, focusing on new compounds, extraction methods and biological activities. As such, approximately 70 articles were identified, which showed 261 new compounds produced by plants of the families Apocynaceae, Rubiaceae, Annonaceae and Loganiaceae. In addition, different extraction methods were identified, and the structures of the new compounds were analysed. In addition to indole molecules, there were mono-indole-, di-indole-, vinblastine-, vimblastine-, gelsedine-, geissospermidine-, koumine-, geissospermidine-, iboga-, perakine-, corynanthe-, vincamine-, ajmaline-, aspidorpema-, strychnos-type, beta-carboline alkaloids and indole alkaloid glucosides. The reported biological activities are mainly anticancer, antibacterial, antimalarial, antifungal, antiparasitic, and antiviral, as well as anti-acetylcholinesterase and anti-butyrylcolinesterase properties. This review serves as a guide for those wishing to find the most recently identified alkaloid structures and their associated activities.

Supramolecular self-assemblies of engineered polyethylenimines as multifunctional nanostructures for DNA transportation with excellent antimicrobial activity

In this study, indole-3-butanoic acid (IBA), a biologically and environmentally safe entity, has been grafted onto low and high molecular weight (1.8 and 25 kDa) polyethylenimines (PEI) mainly through primary amines to obtain amphiphilic indole-3-butanoyl-polyethylenimines (IBPs). Two series of IBPs (IBP1.8 and IBP25) were prepared which, on self-assembly in aqueous medium, yielded multifunctional nanomicellar structures (IBP1.8 and IBP25) capable of transporting genetic material in vitro and exhibiting other biological activities. Physicochemical characterization showed the size of IBP1.8 and IBP25 nanostructures in the range of similar to 332-234 nm and similar to 283-166 nm, respectively, with zeta potential varying from similar to+29-17 mV and similar to+37-25 mV. DNA release assay demonstrated higher release of plasmid DNA from IBP nanostructures as compared to native PEIs. Cytotoxicity showed a decreasing pattern with increasing degree of grafting of IBA onto PEIs making these nanostructures non-toxic. pDNA complexes of these nanostructures (both IBPs(1.8) and IBPs(25)) displayed considerably higher transfection efficiency, however, IBP1.8/pDNA complexes performed much better (similar to 7-9 folds) as compared to native PEI/pDNA and Lipofectamine/pDNA complexes on mammalian cells. CLSM analysis revealed that these complexes entered nucleus in sufficient amounts suggesting higher uptake and efficient internalization of the complexes. Besides, these supramolecular nanostructures not only exhibited excellent antimicrobial potential (MIC similar to 49-100 mu g/ml) against clinical as well as resistant pathogenic strains but also found to possess antioxidant property. Overall, the projected low molecular weight PEI-based vectors could serve as more effective multifunctional nanomaterials having promising potential for future gene therapy applications with capability to provide protection against other bacterial infections.

Revisiting the Cu-ll-Catalyzed Asymmetric Friedel-Crafts Reaction of Indole with Trifluoropyruvate

A Cu-II complex of bisamidine ligand L-s catalyzes the Friedel-Crafts (FC) reaction of indole with trifluoropyruvate with high generality, yielding the highly enantiomerically enriched FC adduct. Electron-rich indoles have high reactivity due to a dual activation mechanism showing second-order kinetics for Cu-II, whereas indoles with a soft substituent at C(4) proceed at a rate that is three orders of magnitude lower via a coordination mechanism, which reverses the sense of enantioselectivity.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 100-51-6, in my other articles.

Reply to the ‘Comment on ”On the positional and orientational order of water and methanol around indole: a study on the microscopic origin of solubility” Phys. Chem. Chem. Phys., 2018, 20, DOI: 10.1039/C7CP03698A’

In his comment on a recent publication by us, G. Graziano claims that solubility differences of indole in methanol and water can be rationalized by the reversible work needed to create a cavity in the solvent of the size of the solute, in this case indole. This quantity, he argues, is closely related to the solvent accessible surface area, which is greater for methanol compared with water, thus making indole more soluble in the former solvent. G. Graziano asserts that it is this property which is responsible for the large difference between the solubilities of indole in methanol and water. Further, G. Graziano claims that the differences in excess entropies and in distance distribution functions of indole in methanol and water and in methanol and water as a cosolvent found in our original work (Henao, et al., Phys. Chem. Chem. Phys., 2016, 18, 23006) are too ”small” to be able to account for the differences in solubility of the indole molecule. We show in this work that the differences found by us are not small, by displaying some selected distance distribution functions in an alternative way to that described in our original paper. In fact we conclude that the differences in these functions are quantitatively greater than those found by Graziano in his comment. Secondly, we show in this reply that although the increase of the solvent accessible surface area may rationalize the differences in the indole-methanol and indole-water binary systems, and thus the work required for cavity creation, it is insufficient to fully account for the increase of indole solubility in water by the addition of very small quantities of methanol in the ternary system indole-methanol-water. In other words, as stated in our original paper, methanol is actively changing the solvation shell and not just passively increasing the solvent accessible surface area around indole. As a result of these additional analyses, we conclude that our work on the solvation differences of indole in water and methanol successfully captures differences in the solvation shells of both solvents around indole in both binary and ternary systems. Finally, while we do agree that Graziano’s calculations are able to capture the role of cavity creation to explain differences in solubility, we think that our results concerning the quantification of changes in molecular interaction should be added to the calculations suggested by him to lead to a full description of the solubility.

Cation-pi binding ability of BN indole

A BN indole-containing aromatic scaffold has been synthesized and the cation-pi binding ability characterized by nuclear magnetic resonance (NMR) monitored titrations. The resulting chemical shifts were analyzed using a non-linear curve fitting procedure and the extracted association constants (K-a’s) compared with the natural indole scaffold. Computations were also performed to support our findings. This work shows that incorporation of a B-N bond in place of a C-C bond in an aromatic system slightly lowers the cation-pi binding ability of the arene’s pi-system with simple cations.

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. you can also check out more blogs about 5471-51-2. Product Details of 5471-51-2.
