Exploring the ethnomycological potential of Lentinus squarrosulus Mont. through GC?MS and chemoinformatics tools

Deciphering the ethnopharmacological importance is one of the prime steps towards understanding the indigenous traditional medicines practised over the centuries. With the advent of modern techniques, it is possible to unravel and explore the hidden ethnopharmacological benefits, comprising complex bioactive compounds of substantial health benefits and together it helps to treat the complex diseases without any side effects as seen in the case of modern synthetic drugs. In this concern, the present study aims to identify the ethnomycologically significant mycocompounds derived from the fruiting body of wild edible macrofungi, Lentinus squarrosulus that contain a vast array of compounds with notable edibility and a wide spectrum of medicinal applications. Proper authentication of mushroom taxonomy was exclusively done using macro and microscopic observations combining ITS DNA-based methods. Further, the isolate was subjected to fractionation in different solvent systems for mycochemical examination followed by GC?MS analysis. A total of 38 mycocompounds were identified through GC?MS and further subjected to in silico studies for drug-likeness, bioactivity and ADMET predictions to explore the druggability of mycocompounds. In silico analysis revealed 10 mycocompounds having good drug-likeness and ADMET properties. Altogether, the present study explored the ethnomycological potential of L. squarrosulus and identified potential mycocompounds.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 7331-52-4, and how the biochemistry of the body works.Product Details of 7331-52-4

Initial pyrolysis mechanism of cellulose revealed by in-situ DRIFT analysis and theoretical calculation

Cellulose is one of the major components of biomass. The study on its pyrolysis process will be beneficial to the in-depth understanding of biomass pyrolysis mechanism. In this work, in-situ diffuse reflectance infrared Fourier transform spectroscopy (in-situ DRIFT) combined with two-dimensional perturbation correlation infrared spectroscopy (2D-PCIS) was first used to characterize the evolution process of the functional groups in cellulose during pyrolysis. The results showed that the degradation of carbon skeleton was prior to the dehydration of free hydroxyls after the destruction of hydrogen bond networks during pyrolysis.

Energy-and carbon-efficient synthesis of functionalized small molecules in bacteria using non-decarboxylative Claisen condensation reactions

Anabolic metabolism can produce an array of small molecules, but yields and productivities are low owing to carbon and energy inefficiencies and slow kinetics1,2. Catabolic and fermentative pathways, on the other hand, are carbon and energy efficient but support only a limited product range3,4. We used carbon-and energy-efficient non-decarboxylative Claisen condensation reactions and subsequent b-reduction reactions, which can accept a variety of functionalized primers and functionalized extender units and operate in an iterative manner, to synthesize functionalized small molecules. Using different v-and v-1-functionalized primers and alpha-functionalized extender units in combination with various termination pathways, we demonstrate the synthesis of 18 products from 10 classes, including omega-phenylalkanoic, a,omega-dicarboxylic, omega-hydroxy, omega-1-oxo, omega-1-methyl, 2-methyl, 2-methyl-2-enolic and 2,3-dihydroxy acids, b-hydroxy-omega-lactones, and omega-1-methyl alcohols.

Direct contact membrane distillation for the treatment of industrial dyeing wastewater and characteristic pollutants

In this work, the feasibility of utilizing direct contact membrane distillation (DCMD) for the treatment of industrial dyeing wastewater and their characteristic pollutants were demonstrated. Two commercial hydrophobic membranes made of polytetrafluoroethylene (PTFE) and polyvinylidene fluoride (PVDF) were comparatively studied. The results suggest that PTFE membrane always demonstrates enhanced flux and rejection performance for selected characteristic pollutants compared with that of PVDF counterpart, which can be ascribed to its enhanced hydrophobicity and reduced wettability. When challenging the industrial and synthetic dyeing wastewater, the DCMD system demonstrates different performances in terms of flux and rejection efficiency, which are closely related to the sample compositions and concentration. The relevant COD and color removal efficiency over 48 h continuous operation was, respectively, 90% and 94% for sample 1# (from discharge outlet of the dyeing vat wastewater), 96% and 100% for sample 2# (from discharge outlet of the wastewater treatment plant after physicochemical and biological treatment), and 89% and 100% for sample 3# (synthetic dyeing wastewater after bench-scale membrane bioreactor treatment). Furthermore, various advanced characterization techniques were employed to study the fouling properties and performance of the PTFE membrane. The suspended solids accumulation (e.g., SiO2 and dispersed dyes) may be responsible for the membrane wetting and fouling. These overall findings suggest that the DCMD process is a promising option for the treatment of dyeing wastewater with limited energy consumption and high performance.

Effectiveness of different solid-phase microextraction fibres for differentiation of selected Madeira island fruits based on their volatile metabolite profile – Identification of novel compounds

A headspace solid-phase microextraction (HS-SPME) procedure based on five commercialised fibres (85 mum polyacrylate – PA, 100 mum polydimethylsiloxane – PDMS, 65 mum polydimethylsiloxane/divinylbenzene – PDMS/DVB, 70 mum carbowax/divinylbenzene – CW/DVB and 85 mum carboxen/polydimethylsiloxane – CAR/PDMS) is presented for the characterization of the volatile metabolite profile of four selected Madeira island fruit species, lemon (Citrus limon), kiwi (Actinidia deliciosa), papaya (Carica papaya L.) and Chickasaw plum (Prunus angustifolia). The isolation of metabolites was followed by thermal desorption gas chromatography-quadrupole mass spectrometry (GC-qMS) methodology. The performance of the target fibres was evaluated and compared. The SPME fibre coated with CW/DVB afforded the highest extraction efficiency in kiwi and papaya pulps, while in lemon and plum the same was achieved with PMDS/DVB fibre. This procedure allowed for the identification of 80 compounds, 41 in kiwi, 24 in plums, 23 in papaya and 20 in lemon. Considering the best extraction conditions, the most abundant volatiles identified in kiwi were the intense aldehydes and ethyl esters such as (E)-2-hexenal and ethyl butyrate, while in Chicasaw plum predominate 2-hexenal, 2-methyl-4-pentenal, hexanal, (Z)-3-hexenol and cyclohexylene oxide. The major compounds identified in the papaya pulp were benzyl isothiocyanate, linalool oxide, furfural, hydroxypropanone, linalool and acetic acid. Finally, lemon was shown to be the most divergent of the four fruits, being its aroma profile composed almost exclusively by terpens, namely limonene, gamma-terpinene, o-cymene and alpha-terpinolene. Thirty two volatiles were identified for the first time in the fruit or close related species analysed and 14 volatiles are reported as novel volatile metabolites in fruits. This includes 5 new compounds in kiwi (2-cyclohexene-1,4-dione, furyl hydroxymethyl ketone, 4-hydroxydihydro-2(3H)- furanone, 5-acetoxymethyl-2-furaldehyde and ethanedioic acid), 4 in plum (4-hydroxydihydro-2(3H)-furanone, 5-methyl-2-pyrazinylmethanol, cyclohexylene oxide and 1-methylcyclohexene), 4 in papaya (octaethyleneglycol, 1,2-cyclopentanedione, 3-methyl-1,2-cyclopentanedione and 2-furyl methyl ketone) and 2 in lemon (geranyl farnesate and safranal). It is noteworthy that among the 15 volatile metabolites identified in papaya, 3-methyl-1,2-cyclopentanedione was previously described as a novel PPARgamma (peroxisome proliferator-activated receptor gamma) agonist, having a potential to minimize inflammation.
