The effects of carbon dots on immune system biomarkers, using the Murine Macrophage cell line RAW 264.7 and human whole blood cell cultures
(MDPI, 2018)
Abstract: Carbon dots (CDs) are engineered nanoparticles that are used in a number of bioapplications
such as bioimaging, drug delivery and theranostics. The effects of CDs on the immune system have
not been evaluated. ...
Cytotoxic, cytostatic and HIV-1 PR inhibitory activities of the soft coral litophyton arboreum
(MDPI, 2013)
Bioassay-guided fractionation using different chromatographic and spectroscopic techniques in the analysis of the Red Sea soft coral Litophyton arboreum led to the isolation of nine compounds; sarcophytol M (1), alismol ...
Oestrogen, testosterone, cytotoxin and cholinesterase inhibitor removal during reclamation of sewage to drinking water
(Water Research Commission, 2013)
Namibia is the driest sub-Saharan country in Africa. Namibia’s capital, Windhoek, reclaims sewage water for domestic use at the Goreangab Water Reclamation Plant (GWRP). Risks associated with sewage effluent and reclaimed ...
An unusual 2,3-secotaraxerene and other cytotoxic triterpenoids from pleiocarpa pycnantha (apocynaceae) leaves collected from Nigeria
(MDPI, 2014)
Three known triterpenoids, namely ursolic acid (1), and the 27-E- and 27-Z-pcoumaric
esters of ursolic acid (compounds 2, 3), were isolated together with a new
triterpene 2,3-seco-taraxer-14-en-2,3-lactone [pycanocarpine ...
Effects of graphene oxide nanoparticles on the immune system biomarkers produced by RAW264.7 and human whole blood cell cultures
(MDPI, 2018)
Graphene oxide nanoparticles (GONPs) have attracted a lot of attention due to their many
applications. These applications include batteries, super capacitors, drug delivery and biosensing.
However, few studies have ...
Imino-quinolyl palladium(II) and platinum(II) complexes: synthesis, characterization, molecular structures and cytotoxic effect
(Elsevier, 2013)
Imino-quinolyl ligands L1-L5 were synthesized by condensation reactions and obtained in good yields. Reactions of the ligands with either PdCl2(cod) or K2[PtCl4] gave the corresponding palladium(II) and platinum(II) complexes ...
Some alkaloids and flavonoids from Cissampelos capensis
(Academic Journals, 2015)
Following the screening of several plant species from an inventory of common medicinal plants from South Africa for medicinal properties, Cissampelos capensis was selected for further investigation due to its interesting ...
Phytochemical screening and biological activity studies of five South African indigenous medicinal plants
(Academic Journals, 2010)
Different extracts and fractions of five selected indigenous South African medicinal plants, namely, Cissampelos capensis, Geranium incanum and three Gethyllis species, were subjected to phytochemical screening and testing ...
Bis(ferrocenylimine)palladium(II) and platinum(II) complexes: synthesis, molecular structures and evaluation as antitumor agents
(Elsevier, 2012)
Compounds (ferrocenyl-2-furylmethyl)imine (L1), (ferrocenyl-2-thiophenemethyl)imine (L2) and (ferrocenyl-2-thiopheneethyl)imine (L3) were synthesized by condensation reactions and obtained in very good yields. Reactions ...
Cytotoxic and cell cycle arrest properties of two steroidal alkaloids isolated from Holarrhena floribunda (G. Don) T. Durand & Schinz leaves
(BMC, 2019)
The plant Holarrhena floribunda (H. floribunda; G. Don) is indigenous to sub-Saharan Africa and is traditionally used to treat several ailments. The present study was carried out to isolate and characterize bioactive ...
