Due to the synergistic effect of the individual ... -
Anticancer activity of ceratotheca triloba
(2016)Plants have provided a source of medicine from the beginning of human history and are the core of modern medicine. Moreover, plant based drug discovery has led to the development of various anticancer drugs (such as ... -
Antimicrobial activity of ciprofloxacin-coated gold nanoparticles on selected pathogens
(2014-08-08)Antibiotic resistance amongst bacterial pathogens is a crisis that has been worsening over recent decades, resulting in serious and often fatal infections that cannot be treated by conventional means. Diseases caused by ... -
Antimicrobial activity of plant phenols from Chlorophora excelsa and Virgilia oroboides
(Academic Journalshttp://www.academicjournals.org/AJB/PDF/pdf2013/24Apr/Padayachee%20and%20Odhav.pdf, 2013-04-24)The anti-bacterial and anti-fungal activity of four aqueous plant extracts (1 x 104 µg/ml) of 2,3'4,5'-tetra hydroxy-4'-geranylstilbene (chlorophorin) and 3',4, 5' - trihydroxy - 4' - geranylstilbene (Iroko) from the tree ... -
Antimosquito properties of 2-substituted phenyl/benzylamino-6-(4-chlorophenyl)-5-methoxycarbonyl-4-methyl-3,6-dihydropyrimidin-1-ium chlorides against anopheles arabiensis
(Bentham Science Publishers, 2014)Eight novel dihydropyrimidine analogs named DHPM1-DHPM8 was synthesized in their hydrochloride salt form using one pot synthesis between methyl 2-chloro-4-(4-chlorophenyl)-6-methyl-1,4-dihydropyrimidine-5-carboxylate and ... -
The antimosquito properties of extracts from flowering plants in South Africa
(NCBI, 2013)Extracts of selected flowering plants, which are considered eco-friendly, are used for the treatment of numerous ailments and vector control worldwide. This has resulted in approximately 25 per cent of currently used drugs ... -
Apoptosis in the human laryngeal carcinoma (HEp-2) cell line by Bulbine natalensis and B. Frutescens fractions
