An efficient synthesis of a series of 4'-oxyalkyl-isocordoin analogues (2-8) is reported for the first time. Their structures were confirmed by ¹H-NMR, 13C-NMR, and HRMS. Their anti-oomycete activity was evaluated by mycelium and spores inhibition assay against two selected pathogenic oomycetes strains: Saprolegnia parasitica and Saprolegnia australis. The entire series of isocordoin derivative...

Biofilms cause chronic infections that are difficult to treat because of the resistance microorganisms inside them. The goal is assess killing potential cefotaxime against Escherichia coli in biofilms obtained from clinical isolates kept microbiology laboratory Dr. Soetomo Surabaya Hospital. study was conducted by experimental design. Two steps challenged bacterial applying planktonic state and...

The antimicrobial property of volatile aromatic oils from medicinal as well as other edible plants has been recognized since antiquity. Candida species are an important cause of opportunistic infections in the oral cavity of immunocompromised patients and vaginal candidiasis. The antifungal activity of the essential oil of Pimento dioica (allspice oil) was investigated against 75 clinical isola...

Dentifrices can augment oral hygiene by inactivating bacteria and at sub-lethal concentrations may affect bacterial metabolism, potentially inhibiting acidogenesis, the main cause of caries. Reported herein is the development of a rapid method to simultaneously measure group-specific bactericidal and acidogenesis-mitigation effects of dentifrices on oral bacteria. Saliva was incubated aerobical...

Among 265 methicillin-susceptible and -resistant staphylococci, CB-181963 (CAB-175) had a 50% minimum inhibitory concentration of 2 microg/ml and a 90% minimum inhibitory concentration of 4 microg/ml. All strains except two vancomycin-resistant S. aureus and 5 vancomycin-intermediate S. aureus strains were also susceptible to vancomycin and teicoplanin, and all were susceptible to linezolid, ra...

Bacterial antibiotic resistance is typically quantified by the minimum inhibitory concentration (MIC), which is defined as the minimal concentration of antibiotic that inhibits bacterial growth starting from a standard cell density. However, when antibiotic resistance is mediated by degradation, the collective inactivation of antibiotic by the bacterial population can cause the measured MIC to ...

P. aeruginosa M14808 was screened to produce rhamnolipid with high yield by mutation in a high magneto-gravitational environment. After silica gel columniation chromatogram, the components of the crude biosurfactant extract were analyzed by TLC, FTIR, and ESI-MS. The major components were characterized as rhamnolipids. The rhamnolipids consisted of two main types, monoand di-rhamnolipids. Di-rh...

This manuscript describes the synthesis of new Au(I) and Ag(I) complexes with aminophosphane ligands and a study of their antibacterial activity against Gram-negative Salmonella enterica serovar typhimurium and Escherichia coli and Gram-positive Listeria monocytogenes and Staphylococcus aureus. The bactericidal assays revealed the effectiveness of these compounds on paradigm Gram-negative and G...
