Bacterial infections represent one of the main threats to global public health. One of the major causative agents associated with high morbidity and mortality infections in hospitals worldwide is methicillin-resistant Staphylococcus aureus. Therefore, there is a need to develop new antibacterial agents to treat these infections, and natural products are a rich source of them. In previous studie...

Cabbage is a rich source of a number of bioactive compounds such as flavonoids, glucosinolates and their breakdown products which may have antibacterial, antioxidant and anticancer properties. Outer green leaves of York cabbage were extracted with 60% methanol, ethanol or acetone. Antibacterial activities of vacuum dried crude extracts were estimated against a number of Gram-positive and Gram-n...

Dental caries is a multifactorial disease that is a growing and costly global health concern. The onset of disease is a consequence of an ecological imbalance within the dental plaque biofilm that favors specific acidogenic and aciduric caries pathogens, namely Streptococcus mutans and Streptococcus sobrinus. It is now recognized by the scientific and medical community that it is neither possib...

In the past decades, honey has been subjected to various laboratory and clinical investigations. The antimicrobial properties of honey have been attributed to both the hydrogen peroxide as well as non-peroxide components. In the present study, three honey samples were collected and four bacterial strains were isolated from ear discharge samples. For the isolation of bacterial strains, the sampl...

Piper betle L. leaf empirically has been used by the community as anti-inflamation, accelerate wound healing and antibacterial. Natural ingredients that have antibacterial activity can be found in hand sanitizer products. The use of products with natural a more environmentally friendly alternative reduce risk dry hands compared to alcohol-based sanitizers. Training on making sanitizers was carr...

A simple, novel, efficient and three-component procedure for the synthesis of pyrimido[4,5-d]pyrimidine-2,4-dione derivatives by the reaction of 6-amino-1,3-dimethyluracil, aldehyde and 2-benzylisothiourea hydrochloride promoted by ionic liquid 1-butyl-3-methylimidazolium bromide ([BMIm]Br) under solvent-free conditions is reported. The presented method is benefited from operational simplicity...

Benzimidazoles are among the most important nitrogen-containing heterocyclic compounds that have many pharmaceutical applications, including antitumor, anticancer, anticorrosive, antibacterial, irritant and enzymatic interceptors. In this research, the synthesis of benzimidazoles by using o-phenylenediamine and aldehyde derivatives in the presence of the nano montemurillonite in solvent-free an...

A three-component reaction between 1,2-phenylenediamine, ferrocenecarbaldehyde, and isocyanides in the presence of a catalytic amount of p-toluenesulfonic acid for the synthesis of 3,4-dihydroquinoxalin-2-amine derivatives containing a ferrocene unit is reported. This approach is an effective procedure because the products have a broad spectrum of biological and pharmacological activities such ...
