Biological activity of aflatoxin B2a.
The toxicity of alfatoxin B(2a) (hydroxydihydro-aflatoxin B(1)) was studied in several biological systems. Aflatoxin B(2a) is the monohydroxylated derivative obtained from addition of water to the double bond of the terminal furan of B(1). Examination of the sensitivity of a group of microorganisms to B(2a) demonstrated that the inhibitory spectrum was similar to aflatoxin B(1). However, the to...
متن کاملDEVELOPMENT OF A RAPID AND SENSITIVE RADIOIMMUNOASSAY FOR MEASUREMENT OF AFLATOXIN B 1 IN BIOLOGICAL SAMPLES
Aflatoxin B I (AFB) isa well known hepatocarcinogen in several animal species and probably a causative agent in human hepatocellular carcinoma. Humans are exposed to AFB by ingesting contaminated food. Aflatoxin contamination encountered in human foods is usually at low levels which is difficult to measure by chromatographic methods. Therefore in the present study we have developed an immun...
متن کاملAflatoxin Detoxification : Hydroxydihydro - Aflatoxin B 1
A large number of microorganisms were screened in shaken-flask culture for their ability to detoxify the fungal toxin, aflatoxin B, (A. Ciegler et al., Appl. Microbiol. 14:934, 1966). We noted formation of a new fluorescing compound with concomitant disappearance of aflatoxin B, when toxin was added to acid-producing mold cultures. Steaming the culture before addition of toxin did not prevent f...
متن کاملStructure and biological activity of lipiarmycin B.
Actinoplanes deccanensis ATCC 21983, the producer of antibiotics lipiarmycin A3 and A4, furnished also a related antibiotic designated lipiarmycin B, active against Gram-positive bacteria, including anaerobes, and against Neisseria. The structures of the two major components, B3 and B4, were elucidated from their physico-chemical properties, 1H and 13C NMR spectra and fast atom bombardment mass...
