Development of a novel agent for control of schistosomiasis is a mandate. anti-schistosomal activity of the aerial parts of were examined. Chromatographic investigations of the ethanol extract (EE) were afforded three compounds. Pregnane glycoside (CI) 12--hydroxy-benzoyl-20-acetyl-boucerin-3--D-glucopyranosyl-(1→4)--D-cymaropyranosyl-(1→4)-D-cymaropyranoside, in addition to two flavonoids (CII) luteolin-4'---D-neohesperidoside and (CIII)quercetin-3-rutinoside were recognized spectral analysis. The schistosomicidal effects were evaluated using scanning electron microscope (SEM). bioassays on the viability (mobility, morphological changes and mortality) of adults, cercariae, miracidia and eggs at different concentrations 2.5, 5, 12.5, 25 and 50 μg/ml of EE and 2.6, 5.2, 13, 26 and 52 μM of CI in incubation times 1,2,4,6,12hrs were carried out. EE and CI evidenced anti-schistosomal activity with a dose and incubation time-dependent fashion. The effect of EE and CI was evident by the topography damage showed by SEM. EE proved moderate cytotoxicity with IC of 8.48 µg/ml.

The use of Gongronema latifolium for the management of various forms of neurological disorders has generated a lot of interest in the need to further investigate its neurotherapeutic constituents. This work, therefore, focused on assessing the inhibitory potential of selected bioactive components derived from G. latifolium against key neurotherapeutic targets and oxidant species associated with neurodegeneration using in vitro analysis and biomolecular modelling.

Background: Wound management is a critical procedure in veterinary practice. A wound is an injury that requires the body's cells' alignment to break down due to external assault, such as trauma, burns, accidents, and diseases. Re-epithelization, extracellular matrix deposition, especially collagen, inflammatory cell infiltration, and development of new blood capillaries are the four features that are used to evaluate the healing process.

Our chemical investigation on the stem of led to the isolation of one new pregnane glycoside, namely, marsdeoside J (compound ) and twelve known compounds. The structure of the new compound was elucidated by spectroscopic analysis including 1D and 2D NMR, HRESIMS, IR, and UV.

SARS-CoV-2 caused pandemic represented a major risk for the worldwide human health, animal health and economy, forcing extraordinary efforts to discover drugs for its prevention and cure. Considering the extensive interest in the pregnane glycosides because of their diverse structures and excellent biological activities, we investigated them as antiviral agents against SARS-COV-2. We selected 21 pregnane glycosides previously isolated from the genus Caralluma from Asclepiadaceae family to be tested through virtual screening molecular docking simulations for their potential inhibition of SARS-CoV-2 M.

Four new steroidal glycosides (1-4), including two steroidal saponins named lililancifoloside B and C (1-2), one pregnane glycoside named lililancifoloside D (3), and one C22-steroidal lactone glycoside named lililancifoloside E (4), together with five known ones (5-9), were isolated from the bulbs of Lilium lancifolium Thunb. By using spectroscopic analysis, including 1D, 2D NMR, and HR-ESI-MS, the structures of 1-4 were elucidated. All isolates were tested for their cytotoxic potential against the MCF-7, MDA-MB-231, HepG2, and A549 cell lines.
