The present study was designed to assess the antimicrobial activity of 19 natural products belonging terpenoids, alkaloids, thiophenes and phenolics against a panel 14 Gram-negative multidrug-resistant (MDR) bacteria. results demonstrated that amongst studied compounds, alkaloids terpenoids were less active contrary flavonoids: neocyclomorusin (3) candidone (6) isoflavonoids: neobavaisoflavone (8) daidzein (12). Thiophene, 2-(penta-1,3-diynyl)-5-(3,4-dihydroxybut-1-ynyl)thiophene (17) showed...
In the current study forty eight compounds belonging to anthraquinones, naphthoquinones, benzoquinones, flavonoids (chalcones and polymethoxylated flavones) diterpenoids (clerodanes kauranes) were explored for their antimicrobial potential against a panel of sensitive multi-drug resistant Gram-negative Gram-positive bacteria. The minimal inhibitory concentration (MIC) determinations on tested bacteria conducted using modified rapid INT colorimetric assay. To evaluate role efflux pumps in...
The methanolic extract (TAE) together with three alkaloids identified as Kokusaginine (1), Maculine (2), Kolbisine (4) and a common terpenoid, Lupeol (3), isolated from the stem bark of Teclea afzelii were tested for their antimicrobial activity against Gram-positive negative bacteria, fungi Mycobacterium smegmatis. Agar diffusion assay was used determination sensitivity test organisms to samples. micro-dilution method determine Minimal Inhibition Concentration (MIC) Microbicidal (MMC)....
Dioscorea bulbifera is an African medicinal plant used to treat microbial infections. In the present study, methanol extract, fractions (DBB1 and DBB2) six compounds isolated from bulbils of D. bulbifera, namely bafoudiosbulbins A (1), B (2), C (3), F (4), G (5) 2,7-dihydroxy-4-methoxyphenanthrene (6), were tested for their antimicrobial activities against Mycobacteria Gram-negative bacteria involving multidrug resistant (MDR) phenotypes expressing active efflux pumps. The microplate alamar...
