Background: is an edible basidiomycete fungus. Both the body and the mycelium contain compounds comprising a wide range of antimicrobial molecules, contributing in improvement of immunity and tumor-retardation.
Objectives: The presence of endophytes capable of producing bioactive compounds was investigated in .
Materials And Methods: Endophytes from was isolated on LB agar. The obtained isolates were characterized morphologically and biochemically. Further 16S rRNA sequencing was implemented for molecular analysis of isolates. The isolate was mass produced and the bioactive compounds were extracted using ethyl acetate, chloroform and hexane. Agar well diffusion method was carried out to seek the potential of any antimicrobial activity of the crude bioactive compounds against known pathogens. GC-MS and FT-IR analysis were performed for the identification of bioactive compounds.
Results: VIT-CMJ2 was identified as as revealed by 16S rRNA sequencing. Chloroform extract of VIT-CMJ2 showed a maximum zone of inhibition of 19 mm against followed by hexane and ethyl acetate extracts. The GC-MS analysis revealed the presence of several bioactive compounds having effective antimicrobial activity like butyl ester, Behenicalcohol, S , S-dioxide derivatives and some others which were later confirmed by FT-IR spectral stretches.
Conclusions: The present study shows the insight on the way endophytes interact with ; thereby improving the nutritional profile.

Antibacterial screening of endophytic fungi from Salacia intermedia identified Diaporthe longicolla as a potent strain exhibiting good activity against multidrug-resistant Staphylococcus aureus and Pseudomonas aeruginosa, with an MIC of 39.1 µg/mL. Scale-up fermentation and chromatographic purification of this strain yielded three known compounds, which were cytochalasin J (1), cytochalasin H (2), and dicerandrol C (3), as identified by liquid chromatography - high mass resolution mass spectrometry (LC-HRMS) and nuclear magnetic resonance (NMR) spectroscopy.

The synthesis of chiral tetrahydroquinolines (THQs) has garnered significant interest from medicinal chemists due to their frequent presence as pharmacophores in bioactive compounds. While existing synthetic methods have primarily focused on THQs with single or multiple endocyclic chiral centers, the selective construction of THQs with both and cyclic chiral centers remains a significant challenge that requires further development. This study introduces a dynamic kinetic resolution (DKR)-based transfer hydrogenation of racemic 2-substituted quinolines, which yields structurally novel chiral THQs with consecutive and cyclic chiral centers in excellent yields and stereoselectivities (59 examples, with generally >20:1 dr and >90% ee, up to three consecutive stereocenters).

This study assessed the anti-diabetic potential and bioactive constituents of ten Sri Lankan medicinal herbs. Initial screening of aqueous extracts for starch-digesting enzyme inhibition prioritised three plants with notable activity ( ≤ 0.05), for further assessment using methanolic extracts: (PE), (CA), and (HI).
