The emergence of multidrug-resistant (MDR) bacteria causes a substantial barrier to treatment, demanding the development of new antibacterial medicines. Myrmecodia pendens (ant nest plant), an indigenous medicinal specie...

Typhoid fever is caused by consuming food or water contaminated with Salmonella typhi. The disease develops from bacterial infection through the consumption of contaminated sustenance and drink. The bacterium can cause b...

The macro fungi of the genus Agaricus have so far recorded many bioactive compounds with antibacterial properties as a product of their metabolism. However, in Ecuador, A. pampeanus or “Kallamba de finados” is a spec...

In this work, we present antibacterial activity of a 22 phenylpropanoids derived from cinnamic acid, recently reported as antifungal agents by our group. Some of these compounds are commercial, others are natural produ...

This study evaluated the antimicrobial activity of the leaves crude ethanol extract of Jacaranda decurrens Cham. (Bignoniaceae). The crude ethanol extract was obtained from the material collected in Senador Canedo and Mo...

In this work the antibacterial activity of two pregnenolone-derivatives was evaluated on V. cholerae and E. coli, using a NCCLS broth dilution modified method. Additionally, to delineate the structural chemical requireme...

Cefoperazone complexes with different metal ions of 1:1 metal to antibiotic stoichiometry have been prepared. The [M(cefopz)CI] complexes (M = Co, Cu and Cd) were characterized by physicochemical and spectroscopic method...

Gemini surfactants are amphiphilic molecules formed by two polar heads and two hydrophobic tails joined by a spacer between the polar groups. Their molecular structure gives them particular physico-chemical properties in...

As a tropical country, Indonesia has a large diversity of flora and fauna, including numerous medicinal plants. Although herbs are widely used for medicinal purposes, their pharmacological effect often varies. This varia...

Abstract One of the critical limitations to use of bacteriocins produced by lactic acid bacteria as a substitute for chemical antibiotics is the narrow spectrum of their antibacterial activity. The aim of present study w...

Background: Conventional glass ionomer cement (GIC) is widely used as a restorative base and liner owing to its chemical adhesion to dentine, fluoride release, and favourable biocompatibility. Nevertheless, its intrinsic...

The persistent escalation of antibiotic resistance poses a severe threat to global public health. As a common opportunistic pathogen, the rapid development of resistance in Escherichia coli (E. coli) poses severe challen...

The research was carried out to analyze the antimicrobial activity of oils from ungurahui fruit, kukui nut, and black cumin seeds. The antimicrobial activity of the oils was evaluated using standard laboratory test strai...
