Research ArticleOpen accessIn the abstractAntibacterial Activity of β-Cyclodextrin and 2-Hydroxypropyl-β-Cyclodextrin Trimethoprim ComplexesHsien-Kuo Sun, Madhumathi Seshadri, Scott Lingard et al.Problem statement: Cyclodextrin complexation has previously been shown to improve the solubility and dissolution properties of trimethoprim; however, no report provides an account of the effect cyclodextrin complexation has on the antibacterial activity of this agent. Approach: β-cyclodextrin and 2-hydroxypropyl β-cyclodextrin inclusion complexes of trimethoprim were prepared and confirmed by differential scanning calorimetry and proton nuclear magnetic resonance. The in-vitro … …Current Research in Microbiology, Vol. 2, Issue 1 · 26 Oct 2011 · 14,801 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAntibacterial Activity of Marine Source Extracts Against Multidrug Resistance OrganismsNagi A. AL-Haj, Nurmas I. Mashan, Mariana N. Shamsudin et al.Problem statement: Antimicrobial resistance is the major problem of global dimensions with a significant impact on morbidity, mortality and healthcare-associated costs. The problem has recently been worsened by the steady increase in multiresistant strains and by the restriction of antibiotic discovery and development programs. Methicillin-resistant Staphylococcus aureus, pseudomonads and Escherichia coli are a major nosocomial and community-acquired pathogens for which … …American Journal of Pharmacology and Toxicology, Vol. 5, Issue 2 · 30 Jun 2010 · 10,073 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAntibacterial and Antioxidant Activities of Typhonium Flagelliforme (Lodd.) Blume TuberSyam Mohan, Ahmad Bustamam Abdul, Siddig Ibrahim Abdel Wahab et al.Problem Statement: Multiple drug resistance in human pathogenic micro organisms has developed due to indiscriminate use of modern antimicrobial drugs generally used in the management of infectious diseases. This increases the importance of exploiting the natural sources instead modern drugs. Approach: The antibacterial and antioxidant activity of different extracts from of Typhonium flagelliforme (L.) Blume tuber (family: Araceae) commonly called … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 10,420 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordPhytochemical Composition, Antibacterial, and Antioxidant Properties of Foeniculum vulgare Essential OilSaif M. Dmour, Saqr Abushattal, Sultan Ayesh Mohammed Saghir et al.This study intended to inspect the phytochemical composition and bioactivity of Fennel (Foeniculum vulgare) Seed Essential Oil (FSEO) from Jordan. The EO was extracted via hydrodistillation from air-dried samples with 4.42% (v/w) yield. Twenty compounds, constituting around 98.5% of the EO were identified using Gas Chromatography-Mass Spectrometry (GC-MS). Estragole (47.15%) and Anethole (36.2%), appeared as predominant oxygenated monoterpenes compounds in … …OnLine Journal of Biological Sciences, Vol. 25, Issue 3 · 1 Aug 2025 · 4,638 accessesView PDF Cite
