A series of (28) 1-alkyl-3-methacryloyl (acryloyl)-benzimidazolone (thione) deriv-atives were synthesized. The structures of the new derivatives were confirmed by (1)H-NMR, (13)C-NMR and ESI-MS spectral analysis. The antibacterial activities of these compounds against several strains of bacteria, such as Bacillus cereus, Bacillus subtilis, Escherichia coli, Staphylococcus aureus and Pseudomonas...

The aim of this study was to evaluate and compare the antimicrobial activity and cytocompatibility of six different pulp-capping materials: Dycal (Dentsply), Calcicur (Voco), Calcimol LC (Voco), TheraCal LC (Bisco), MTA Angelus (Angelus), and Biodentine (Septodont). To evaluate antimicrobial activity, materials were challenged in vitro with Streptococcus mutans, Streptococcus salivarius, and St...

The aim of the study is to evaluate the antibacterial activity of Pistacia integerrima, Cedrus deodara and Gymnema sylvestre against seven different microorganisms such as Escherichia coli, Salmonella typhi, Klebsiella pneumoniae, Proteus vulgaris, Pseudomonas, Bacillus subtillis and Staphylococcus aureus by using disc diffusion method. Preliminary studies with ethanol extract and water extract...

This study screened the antidiarrhoeal, antimicrobial and cytotoxic effects of ethanol-extracted leaves of yellow oleander (Thevetia peruviana). The extract was tested against castor oil-induced diarrhoea in a model of albino rats and showed significant antidiarrhoeal activity (P<0.01). Disc diffusion technique was used to test the in vitro antibacterial activities of the extract and exhibited ...

The objective of this study was to evaluate different biological activities of aqueous and ethanolic extracts from Thymelaea microphylla. Antioxidant capacity was determined using two methods: 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay, and the inhibition of lipid peroxidation using the β-carotene/linoleate model system. Disc diffusion method was used to evaluate the antibact...

Objective: The study was conducted to investigate the antibacterial and anthelmintic activities and to determine total phenolic contents of methanolic extract of Piper betel leaves. Materials and Methods: The extract was subjected to assay for antibacterial activity using both gram positive and gram negative bacterial strains through disc diffusion method; anthelmintic activity with the determi...

Mastitis is one of the most costly diseases in the dairy industry. The use of antibiotics in the treatment of mastitis Leads to bacterial resistance and health problems for consumers. This study aimed to determine the antibacterial properties of essential oil of Thymus vulgaris on the bacteria Staphylococcus aureus, Escherichia coli and Staphylococcus were agalactia. Antibacterial properties of...

Ethanolic extract of fresh leaves of Acalypha wilkesiana was screened for its phytochemical and invitro antibacterial properties on four clinical isolates Staphylococcus aureus, Escherichia coli , Shigella sp , and Klebsiella pneumonia. The disc diffusion technique was used to assay for the antimicrobial properties. The results showed that the extract of concentrations between 50mg/ml to 200mg/...

Penelitian terhadap ekstrak metanol, fraksi etil asetat, dan butanol dari rumput laut Eucheuma spinosum menggunakan metode Disc Diffusion Test dilakukan untuk mengetahui peranannya sebagai antibakteri Escherichia coli ATCC 25922, Staphylococcus aureus 6538. Sebagai kontrol digunakan (negatif) pelarut Amoxicilin. Konsentrasi sampel uji ditetapkan 10.000 ppm. Hasil pengujian menunjukkan adanya ak...
