This review presents the biological activity-antibacterial, antifungal, anti-parasitic, antiviral, antitumor, antiinflammatory, antioxidant, and enzymatic activity-of halogenated marine natural products discovered in the past five years. Newly discovered examples that do not report biological activity are not included.

conclusions potato peels were proved to be potentially useful substrates for biosurfactant production by b. pumilus dsvp18. the strain possessed a unique property to reduce surface tension of the media from 72 to 28.7 mn/m. in addition, it showed a stable surface activity over a wide range of temperatures, ph, and saline conditions and had strong antimicrobial activity. this potential of the id...

Antimicrobials are classified by the pathogens targeted, e.g. as antibacterials or antifungals. This grouping may be subdivided as antibacterials also include urinary antiseptics and anti-mycobacterial drugs. Antimicrobials, especially antibacterials, are strictly classified into chemotherapeutic agents (synthetic chemicals), and antibiotics, produced from living organisms, usually fungi. Howev...

The concept of phage therapy to treat bacterial infections was born with the discovery of the bacteriophage almost a century ago. After a chequered history, its current renaissance is fueled by the dangerous appearance of antibiotic-resistant bacteria on a global scale. As a mark of this renewed interest, the unanswered problems of phage therapy are now being addressed, especially for human use...

A prototypical patient is presented to introduce important design issues for clinical trials of antibacterials in the treatment of ventilator-associated bacterial pneumonia.

New antibiotics with novel mechanisms of action are urgently needed to overcome the growing bacterial resistance problem faced by clinicians today. PC190723 and related compounds represent a promising new class of antibacterial compounds that target the essential bacterial cell division protein FtsZ. While this family of compounds exhibits potent antistaphylococcal activity, they have poor acti...

burns are known as one of the most common forms of injury with devastating consequences. despite the discovery of several antiseptics, burn wound healing has still remained a challenge to modern medicine. herbal products seem to possess moderate efficacy with no or less toxicity and are less expensive compared to synthetic drugs. burn is a well-known disorder in iranian traditional medicine (it...

A simple microbiological method to identify antimicrobial agents in urine is described. Of 1,514 consecutive urine specimens received from general practitioners, 302 (19.94%) contained antimicrobial activity. The antibacterial agent was identified confidently in 284 of these. Surprisingly, 83 (5.48%) urine specimens contained an antimicrobial substance not usually used in the treatment of urina...

In the last decade we have witnessed a dramatic increase in the proportion and absolute number of bacterial pathogens resistant to multiple antibacterial agents. Multidrug-resistant bacteria are currently considered as an emergent global disease and a major public health problem. The B-Debate meeting brought together renowned experts representing the main stakeholders (i.e. policy makers, publi...
