Abstract Dihydroisobenzofuran heterocycle is a structural motif found in number of medications with anti-tumour, anti-diabetic, and antibacterial activities. It also slew natural substances, most notably fungus metabolites, which have been shown to possess credible radical scavenging activity. Density functional theory studies on three different derivatives were conducted investigate their elec...

Streptomyces has been known as a source of natural bioactive substances so far. In this present study, the sponge-derived HM9 was optimised with number different carbon (C) and nitrogen (N) sources to evaluate broad-spectrum antibacterial ability. Starch (NH4)2SO4 were favourable growth strain HM9. casein suitable for activity against Vibrio, whereas lactose NH4Cl beneficial on inhibition stand...

2 RÉSUMÉ Flo, un peptide antibactérien isolé de l'arbre tropical Moringa oleifera: Une base pour de nouvelles substances antibactériennes Les peptides antimicrobiens sont essentiels à la survie d'organismes multicellulaires. Ils servent à lutter contre des microbes pathogènes et à contrôler les communautés commensales inoffensives. Jusqu'à aujourd'hui ces peptides n'ont pas permis aux microbes ...

BACKGROUND AND OBJECTIVES Regarding the importance of finding new antibacterial drugs, screening of plants as a promising resource are now conducted worldwide. In this study, we report the application of a simple previously described method for screening of different plant seeds in order to find the best resources of plant antimicrobial peptides. MATERIALS AND METHODS Total water soluble prot...

Determining the susceptibility of pathogens to antibacterial substances is one key steps in bacteriological diagnostics that affects success both therapeutic therapy and appropriate selection cosmetic products. Antibiotic chemotherapeutic sensitivity tests determine ability an antimicrobial agent inhibit growth a microorganism vitro.

Applanoxidic acids and sterols, isolated from Ganoderma spp., were acetylated and/or methylated. The antibacterial activity against Escherichia coli and Staphylococcus aureus and the antifungal activity against Candida albicans and Trichophyton mentagrophytes of the derivatives were investigated by a microdilution method, and compared with those of the natural products. Both natural and modifie...

Royal jelly (RJ), a highly nutritious natural product, has gained recognition for its remarkable health-promoting properties, leading to widespread use in the pharmaceutical, food, and cosmetic industries. Extensive investigations have revealed that RJ possesses broad spectrum of therapeutic effects, including anti-inflammatory, antioxidant, antitumor, anti-aging, antibacterial activities. Dist...

There are at least three reasons for the need in finding out new alternative antimicrobial substances from natural sources. The first reason is that people nowadays concern about toxic of synthetic substances including daily contact chemicals or even drugs used in medical or healthcare purposes (Hafidh et al., 2009). Any synthetic drugs were avoided in order to keep physiological cleans as beli...
