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.

Application of an efficient indole oxygenase system from Cupriavidus sp. SHE for indigo production

Indigo, one of the most widely used dyes, is mainly produced by chemical processes, which generate amounts of pollutants and need high energy consumption. Microbial production of indigo from indole has attracted much attention; however, the indole oxygenase has never been explored and applied for indigo production. In the present study, the indole oxygenase indAB genes were successfully cloned from Cupriavidus sp. SHE and heterologously expressed in Escherichia coli BL21(DE3) (designated as IND_AB). Strain IND_AB produced primarily indigo in tryptophan medium by high-performance liquid chromatography-mass spectroscopy (HPLC-MS) analysis. The preferable conditions for indigo production were pH 6.5 (normal pH), 30 degrees C, 150 rpm, strain inoculation concentration OD600 0.08, and induction with 1 mM IPTG at the time of inoculation. The optimal culture medium compositions were further determined as tryptophan 1.0 g/L, NaCl 3.55 g/L, and yeast extract 5.12 g/L based on single-factor experiment and response surface methodology. The highest indigo yield was 307 mg/L, which was 4.39-fold higher than the original value. This is the first study investigating indigo production using the indole oxygenase system and the results highlighted its potential in bio-indigo industrial application.

Direct somatic embryogenesis using leaf explants and short term storage of synseeds in Spathoglottis plicata Blume

Spathoglottis plicata Blume is a vulnerable orchid species in various parts of the world, and the conventional propagation provides limited success to its cultivation and conservation. Therefore, present study deals with the direct induction of somatic embryos (SEs) from the leaf explants of S. plicata. Murashige and Skoog’s (MS) medium fortified with various types and concentrations of plant growth regulators were used to induce somatic embryogenesis and plantlet production. The highest percentage of somatic embryo formation (93.7 +/- 0.56%) was achieved on MS medium supplemented with 1.0 mg L-1 2,4-dichlorophenoxyacetic acid (2,4-D), whereas, maximum proliferation and increase in fresh weight (FW) of SEs (149.5 +/- 0.24 mg/ 50 mg initial FW) was achieved on MS medium fortified with 2.0 mg L-1 6-benzylaminopurine (BAP) within 5 weeks of incubation. The light microscopic observation revealed that SEs emerged directly from the leaf surface. The viable synthetic seeds (SS) from SEs were prepared by encapsulating with gel matrix of 3% (w/v) sodium alginate and 100 mM calcium chloride. The SS were successfully stored for 60 days at – 4 degrees C with 97.4% germination frequency and shoot proliferation using MS medium with 2.0 mg L-1 BAP and 0.25 mg L-1 indole-3-acetic acid. The synergistic rooting frequency was observed on half-strength MS medium with 1.0 mg L-1 indole-3-butyric acid. The rooted shoots were acclimatized in a greenhouse with a 90% survival rate using soilrite (R) and vermicompost. This is an efficient short-term storage and regeneration protocol for S. plicata, which could help in reducing pressure on its wild population and could also be extended to the cryopreservation of this orchid species.

Efficient extraction of indole from wash oil by quaternary ammonium salts via forming deep eutectic solvents

Indole plays a significant role in the production of products such as spices, medicines, and exogenous auxins. Deep eutectic solvents (DESs) formed by indole and quaternary ammonium salts (QASs, including tetraethylammonium chloride-TEAC, tetrapropylammonium chloride-TPAC, triethylmethyl-ammonium chloride-TEMAC) were found and proposed to efficiently extract indole from model wash oil. The effects of time, temperature, mole ratio of QAS to indole and initial indole concentration on the extraction of indole were studied. The results indicate that these QASs can extract indole from wash oil with efficiencies up to 96.7% (TPAC). The extraction process can be finished within 5 min. It is also found that the ultimate concentrations are almost identical for one kind of QAS although their initial concentrations are different, and the indole concentration in model wash oil can be reduced to a very low level of 1.3 g/dm(3) (TPAC). The maximum distribution coefficients of indole are 40.8 for TEAC, 91.9 for TPAC, and 29.5 for TEMAC at the studied conditions, and the extraction ability follows the order of TPAC > TEAC > TEMAC. Moreover, QASs in DESs can be reused without obvious reduction in extraction efficiency. The extraction mechanism was studied by FT-IR, and the results indicate that there is a hydrogen bond between QAS and indole. Finally, a comparison was made between this method and other methods to verify and demonstrate its desirable properties of efficiency and environmentally friendliness.

Sandwich-like Structure of Indole and Carbon Dioxide with Efficient CO2 Capture and Conversion

A hydroxyl-containing and aniline-functionalized indole-based microporous organic polymer (MOP) material poly(hydroxyl indole)-NH2 (PHOIN-NH2) has been successfully designed and synthesized. It was first proven that, due to the electron-rich benzene ring of the aniline group and the electron donor hydroxyl groups donating their electron density to the inner indole ring, the highly electron-rich pi indole plane can simultaneously attract two CO2 molecules via the double local dipole-pi interactions, thereby forming a CO2-indole-CO2 sandwich-like structure and endowing this microporous material with a remarkable CO2, adsorption capacity (33 wt %). In addition, due to the classical acid-base interaction between the aniline group in the PHOIN-NH2 aerogel and the CO2 molecule, the resulting material displays excellent gas selectivity (CO2/N-2 = 146, CO2/CH4 = 24). Moreover, the phenolic-OH groups in the PHOIN-NH2 aerogel provide an abundance of sites for anchoring Zn2+ via metal-coordination interactions for effective conversion of CO2 into propylene carbonate.

Synthesis, characterization and electrochemical properties of some biologically important indole-based-sulfonamide derivatives

A new series of indole-based-sulfonamide derivatives (A1-A8) was synthesized by treating 5-fluoro-1H-indole-3-carbohydrazide with different aryl-sulfonyl chloride in the presence of pyridine. All synthesized derivatives (A1-A8) were characterized by different analytical methods. The electrochemical behavior of these compounds (A1-A8) was investigated in detail using cyclic voltammetry (CV) and square wave voltammetry (SWV) at the pencil graphite electrode (PGE). In the present study, the redox behavior of all derivatives varies due to the nature of substitutions in the indole sulfonamide moiety. Various fundamental electrochemical parameters, including the standard heterogeneous rate constants (k(s)), and the electroactive surface coverage (Gamma) were calculated from the obtained CVs. The obtained results shed light on the understanding of structure-activity relationships of this class of compounds.
