Isolation of natural compounds from Phlomis stewartii showing α-glucosidase inhibitory activity.
TLDR
The structures of these isolates (1-12) were elucidated by the combination of 1D ((1)H and (13)C NMR), 2D (HMQC, HMBC COSY, NOESY) NMR spectroscopy and mass spectrometry and in comparison with literature data of related compounds.
Cryptosporioptide: a bioactive polyketide produced by an endophytic fungus Cryptosporiopsis sp.
TLDR
Cryptosporioptide exhibited both lipoxygenase inhibitory and anti-Bacillus megaterium activities and the absolute configuration was established by means of electronic circular dichroism (ECD).
α-Glucosidase inhibitory constituents from Chrozophora plicata
Abstract Five new secondary metabolites have been isolated from Chrozophora plicata including an acacetin derivative ( 1 ), three pyrrole alkaloids plicatanins A–C ( 2 – 4 , resp.) and the bilactone
Marine natural products of fungal origin.
TLDR
This review article contains 103 marine-derived fungal metabolites and 77 references about marine fungi that have been investigated to a limited extent for drug discovery.
New Lipoxygenase‐Inhibiting Constituents from Calligonum polygonoides
Calligonolides A (1) and B (2), two new butanolides, and a new steroidal ester, 3, have been isolated from the whole plant of Calligonum polygonoides, together with four known compounds,
Sediment yield assessment and identification of check dam sites for Rawal Dam catchment
Sediment yield is the amount of erosional debris from drainage basin deposited in reservoirs. The economic life of storage reservoir depends upon the estimation of the time it takes for the reservoir
New acylated flavonoid glycosides from flowers of Aerva javanica
TLDR
Chromatographic purification of ethyl acetate soluble fraction of the methanolic extract of the flowers of Aerva javanica yielded three new acylated flavone glycosides, which showed weak inhibitory activity against enzymes.
Bioactive phenolics from Seriphidium stenocephalum
TLDR
Chromatographic separation of the ethyl acetate soluble part of the methanolic extract from Seriphidium stenocephalum yielded three new compounds, which exhibited significant activity against all the tested enzymes, whereas compounds 2 and 3 were found inactive.
Mutiniside, new antioxidant phenolic glucoside from Abutilon muticum
TLDR
Mutiniside, new phenolic glucoside, and the flavonoidal glucosides cephacoside have been isolated from the n-BuOH soluble fraction of Abutilon muticum and showed significant antioxidant activity while moderate inhibitory activity was observed against the enzyme lipoxygenase.
