3-farnesyl-2-hydroxybenzoic acid is a new anti-helicobacter pylori compound from piper multiplinervium.a new prenylated salicylic acid derivative, 3-farnesyl-2-hydroxy benzoic acid (1), was isolated from the leaves of piper multiplinervium c. dc. (piperaceae). it showed anti-helicobacter pylori activity (mic 37.5 microg/ml) and antimicrobial activity at mics between 2.5 and 5 microg/ml against staphylococcus aureus, escherichia coli, klebsiella pneumoniae, mycobacterium smegmatis, pseudomonas aeruginosa and candida albicans. its structure was elucidated by means of ms, 1h and 13c nmr. the ethnome ...200616266794
[analysis of helicobacter pylori infection in a healthy panamanian population].infection with helicobacter pylori carrying a caga virulence gene is a potential risk factor for gastric cancer. since obtaining clinical isolates from healthy subjects is difficult, epidemiological analysis of caga-positive h. pylori in healthy populations is not well studied. to assess h. pylori infection in a healthy population, we applied coprodiagnostic analysis to determine h. pylori infection prevalence. h. pylori antigen in stool specimens was detected by immunochrmoatograpy in 54.1% of ...200919364040
