Isolation and Characterization of Antibacterial Compounds from Aspergillus fumigatus: An Endophytic Fungus from a Mangrove Plant of the Sundarbans

Evidence-Based Complementary and Alternative Medicine, Volume 2022, Issue 1, 2022., 2022
The Sundarbans, a UNESCO world heritage site, is one of the largest mangrove forests in one stretch. Mangrove plants from this forest are little studied for their endophytic fungi. In this study, we isolated fourteen endophytic fungi from the plants Ceriops decandra and Avicennia officinalis collected from the Sundarbans.

Membrane composition is a functional determinant of NIR‐activable liposomes in orthotopic head and neck cancer

Nanophotonics, Volume 10, Issue 12, Page 3169-3185, September 2021., 2021
Abstract Near‐infrared (NIR)‐activable liposomes containing photosensitizer (PS)‐lipid conjugates are emerging as tunable, high‐payload, and tumor‐selective platforms for photodynamic therapy (PDT)‐based theranostics. To date, the impact that the membrane composition of a NIR‐activable liposome (the chemical nature and subsequent conformation of PS ...

HPLC/MS‐MS Identification of Oak Quercus aegilops Root Tannins

Journal of Chemistry, Volume 2021, Issue 1, 2021., 2021
Tannins are natural polyphenolic compounds widely distributed in the plant kingdom in the leaves, bark, fruits, and other parts. They have various biological functions in humans and animals and are used mainly in the pharmaceutical and cosmetic industries. The aim of this work was to isolate, extract, purify, and identify the tannins from the root bark

Formaldehyde as a Chemical Defence Agent of Fruiting Bodies of Mycena rosea and its Role in the Generation of the Alkaloid Mycenarubin C

ChemBioChem, Volume 21, Issue 11, Page 1613-1620, June 2, 2020., 2020
Natural protection: Mycenaubin C, a pyrroloquinoline alkaloid with an unprecedented core structure, was isolated from fruiting bodies of M. rosea. The alkaloid is generated from mycenarubin A and formaldehyde. The amounts of formaldehyde present in the fruiting bodies of M. rosea exhibit a fungistatic effect against the mycoparasite S. fusiger. In turn,

Total Synthesis of Tri‐, Hexa‐ and Heptasaccharidic Substructures of the O‐Polysaccharide of Providencia rustigianii O34

Chemistry – A European Journal, Volume 26, Issue 28, Page 6264-6270, May 15, 2020., 2020
Embedded fucoses: First syntheses of substructures of the O‐polysaccharide of Providencia rustiginii O34 are presented. The repeating unit is a heptasaccharide with seven different monosacchride units (see figure). Abstract A general and efficient strategy for synthesis of tri‐, hexa‐ and heptasaccharidic substructures of the lipopolysaccharide of ...

Ellagic acid derivatives from Terminalia chebula Retz. downregulate the expression of quorum sensing genes to attenuate Pseudomonas aeruginosa PAO1 virulence. [PDF]

PLoS ONE, 2013
BACKGROUND: Burgeoning antibiotic resistance in Pseudomonas aeruginosa has necessitated the development of anti pathogenic agents that can quench acylhomoserine lactone (AHL) mediated QS with least risk of resistance.

A piperic acid CoA ligase produces a putative precursor of piperine, the pungent principle from black pepper fruits

The Plant Journal, Volume 102, Issue 3, Page 569-581, May 2020., 2020
Summary Black pepper (Piper nigrum L.) is known for its high content of piperine, a cinnamoyl amide derivative regarded as largely responsible for the pungent taste of this widely used spice. Despite its long history and worldwide use, the biosynthesis of piperine and related amides has been enigmatic up to now.

Neutralization of pharmacological and toxic activities of Bothrops jararacussu snake venom and isolated myotoxins by Serjania erecta methanolic extract and its fractions

Journal of Venomous Animals and Toxins including Tropical Diseases, 2011
Most of the snakebites recorded in Brazil are caused by the Bothrops genus. Given that the local tissue damage caused by this genus cannot be treated by antivenom therapy, numerous studies are focusing on supplementary alternatives, such as the use of ...

Preparative Isolation of Two Prenylated Biflavonoids from the Roots and Rhizomes of Sinopodophyllum emodi by Sephadex LH-20 Column and High-Speed Counter-Current Chromatography

Molecules, 2015
Two prenylated biflavonoids, podoverines B–C, were isolated from the dried roots and rhizomes of Sinopodophyllum emodi using a Sephadex LH-20 column (SLHC) and high-speed counter-current chromatography (HSCCC).
