Indole Alkaloids as New Leads for the Design and Development of Novel DPP-IV Inhibitors for the Treatment of Diabetes

Background: Inhibition of DPP-IV enzyme is an effective strategy for the treatment of type-2 diabetes mellitus, which involves the degradation of incretin hormones, glucagon like peptide (GLPI ) and gastric inhibitory polypeptide (GIP), being valuable in glucose tolerance and insulin secretion. A series of indole alkaloids from the medicinal plant Rauvolfia serpentina were identified as novel DPP-IV inhibitors using insilico prediction. Objective: Our study is aimed to identify the novel DPP-IV inhibitors for the treatment of diabetes through system level investigation. Method: Computational simulation techniques were used to analyze the molecular interaction between DPP-IV and a series of indole alkaloids. 3D structures of the indole alkaloids were retieved from Pubchem and PRIME KNApSAck databases. Online tools such as Molinspiration, ADMET and drug likeness properties of the indole alkaloids were investigated. Based on the minimum binding energy, stability of the docked complex was evaluated by molecular dynamic simulation. Results: Among the 20 indole alkaloids investigated, molecular docking analysis revealed that yohimbine has higher binding energy compared to other indole alkaloids. It exhibits three it – it stacking interactions with amino acids in hydrophobic S1 and S2 pocket of DPP-IV receptor. Different parameters like binding energy, intermolecular energy, inhibition constant and H-bonding between the ligands & the target were used to determine the extent of inhibition. Interestingly, 5 intermolecular hydrogen bonds were formed between receptor-inhibitor complex to facilitate inhibition. The stability of the docked complex was confirmed by molecular dynamics simulation. Conclusion: DPP-IV enzyme has a significant role in the regulation of glucose metabolism. Among the 20 indole alkaloids, yohimbine has a good binding energy towards DPP-IV and inhibits its function. Thus, yohimbine compound acts as a novel DPP-IV inhibitor for the treatment of type-2 diabetes.

Recent Applications of Heteropolyacids and Related Compounds in Heterocycle Synthesis. Contributions between 2010 and 2020

Over the past two decades, polyoxometalates (POM) have received considerable attention as solid catalysts, due to their unique physicochemical characteristics, since, first, they have very strong Bronsted acidity, approaching the region of a superacid, and second, they are efficient oxidizers that exhibit rapid redox transformations under fairly mild conditions. Their structural mobility is also highlighted, since they are complex molecules that can be modified by changing their structure or the elements that compose them to model their size, charge density, redox potentials, acidity, and solubility. Finally, they can be used in substoichiometric amounts and reused without an appreciable loss of catalytic activity, all of which postulate them as versatile, economic and ecological catalysts. Therefore, in 2009, we wrote a review article highlighting the great variety of organic reactions, mainly in the area of the synthesis of bioactive heterocycles in which they can be used, and this new review completes that article with the contributions made in the same area for the period 2010 to 2020. The synthesized heterocycles to be covered include pyrimidines, pyridines, pyrroles, indoles, chromenes, xanthenes, pyrans, azlactones, azoles, diazines, azepines, flavones, and formylchromones, among others.

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 1693-37-4, in my other articles.

Ultrathin Amorphous/Crystalline Heterophase Rh and Rh Alloy Nanosheets as Tandem Catalysts for Direct Indole Synthesis

Heterogeneous noble-metal-based catalysis plays an essential role in the production of fine chemicals. Rh-based catalysts are one of the most active candidates for indole synthesis. However, it is still highly desired to develop heterogeneous Rh-based catalysts with high activity and selectivity. In this work, a general, facile wet-chemical method is reported to synthesize ultrathin amorphous/crystalline heterophase Rh and Rh-based bimetallic alloy nanosheets (NSs), including RhCu, RhZn, and RhRu. Impressively, the amorphous/crystalline heterophase Rh NSs exhibit enhanced catalytic activity toward the direct synthesis of indole compared to the crystalline counterpart. Importantly, the obtained amorphous/crystalline heterophase RhCu alloy NSs can further enhance the selectivity to indole of >99.9% and the conversion is 100%. This work demonstrates the importance of phase engineering and metal alloying in the rational design and synthesis of tandem heterogeneous catalysts toward fine chemical synthesis.

Gold-catalyzed stereoselective dearomatization/metal-free aerobic oxidation: access to 3-substituted indolines/oxindoles

An unprecedented dearomatization of indoles with diazoesters has been developed via cationic gold(I) catalysis. The functionalization selectively occurs at the C3-position to deliver methylene indole derivatives in good yields with excellent Z-selectivity, demonstrating unusual reactivity and selectivity compared with other noble metal catalysis. Importantly, simply followed by silica gel adsorption, an unprecedented metal-free aerobic oxidation occurs for indoles bearing N-electron donating substituents, providing a novel and efficient approach towards 3-substituted indolin-2-ones with a newly formed quaternary stereocenter in excellent stereoselectivity. Notably, these processes afford direct and selective access to a variety of valuable intermediates from abundant feedstock chemicals.

Development of electrochemical and optoelectronic performance of new 7-{[1H-indol-3-ylmethylidene]amino}-4-methyl-2H-chromen-2-one dye

A new 7-{[1H-indol-3-ylmethylidene]amino}-4-methyl-2H-chromen-2-one dye (3) was synthesized by the reaction of 7-amino-4-methyl coumarin with indole-3-carbaldehyde in EtOH using GAA as a catalyst. The photophysical properties of the synthesized compound were studied using UV-visible and photoluminescence spectrophotometer. Redox onset potential for the dye compound was recorded through a cyclic voltammogram (CV), which aids to calculate the highest occupied molecular orbital (HOMO)-lowest unoccupied molecular orbital (LUMO) values. The experimental and theoretical HOMO-LUMO values were calculated using the density functional theory (DFT). Moreover, the I-V characteristics were evaluated by two-sense Keithley source in dark and light medium by using a mercury lamp as a light source. The results of the I-V study showed that the compound (3) possesses good light-absorbing capability with a high molar absorption extinction coefficient (0.80 x 10(-5) epsilon). Therefore, the I-V characteristics suggest the efficiency of obtained dye for photovoltaic uses.

Differentiating alkyne reactivity in the post-Ugi transformations: Access to polycyclic indole-fused frameworks

The Ugi adducts prepared from propiolic acids, propargylamines, indole-2-carbaldehydes, and isocyanides were utilized to assemble polycyclic indole-fused frameworks via two consecutive carbocyclizations involving triple bonds. First, the peptidyl position of Ugi adduct underwent potassium carbonate-mediated cyclization onto the triple bond derived from propiolic acid. Then, the position 3 of indole core engaged into gold-catalyzed cyclization onto the propargylamine-originated alkyne, completing the construction of polycyclic core. (C) 2018 Elsevier Ltd.

Discovery of a novel indole pharmacophore for the irreversible inhibition of myeloperoxidase (MPO)

Myeloperoxidase (MPO) activity and subsequent generation of hypochlorous acid has been associated with the killing of host-invading microorganisms (e.g. bacteria, viruses, and fungi). However, during oxidative stress, high MPO activity can damage host tissue and is linked to several chronic inflammatory conditions. Herein, we describe the development of a novel biaryl, indole-pyrazole series of irreversible mechanism-based inhibitors of MPO. Derived from an indole-containing high-throughput screen hit, optimization efforts resulted in potent and selective 6-substituted indoles with good oral bioavailability and in vivo activity.
