Mycophenolic acid in silage.
We examined 233 silage samples and found that molds were present in 206 samples with counts between 1 x 10(3) and 8.9 x 10(7) (mean, 4.7 x 10(6)) CFU/g. Mycophenolic acid, a metabolite of Penicillium roqueforti, was detected by liquid chromatography-mass spectrometry in 74 (32%) of these samples at levels ranging from 20 to 35,000 (mean, 1,400) microg/kg. This compound has well-known immunosupp...

n our laboratory in 4CS mice. (3) Mouse ascites hepatoma, MH134, was converted into ascitic form by Sato et al.*\ from a C3H/HeN mouse hapatoma induced after treatment with carbon tetrachloride by Andervont et al.5) It has been maintained in C3H/He mice with distinct strain specificity in tumor take in our laboratory. (4) Mouse ascites sarcoma, SR-C3H/He Th62, was originally induced with Schmid...
متن کاملQuantification of mycophenolic acid and glucuronide metabolite in human serum by HPLC-tandem mass spectrometry.
BACKGROUND The potent immunosuppressant mycophenolic acid (MPA) is metabolized to an inactive glucuronide (MPAG). The extent of metabolism varies among individuals, and the MPAG formed can be hydrolyzed to MPA and can displace MPA from serum albumin, creating a potential need to monitor both MPA and MPAG. METHODS After addition of the carboxybutoxy ether of MPA (MPAC) as internal standard, MP...
متن کاملIMP-dehydrogenase inhibition in human lymphocytes and lymphoblasts by mycophenolic acid and mycophenolic acid glucuronide.
Inosine 5'-monophosphate dehydrogenase (IMP-DH) activities were measured in human lymphocytes (exhibiting type I IMP-DH activity) and human lymphoblasts (exhibiting type II IMP-DH activity) in the presence of various amounts of mycophenolic acid (MPA) (0-20 mumol/L) and MPA glucuronide (MPAG) (0-200 mumol/L). Moreover, the influences of human serum albumin (HSA) and human plasma on the MPA- and...
متن کاملSome biological properties of mycophenolic acid.
Mycophenolic acid (MA) inhibits the growth of some pathogenic fungi such as Candida albicans, Cryptococcus neoformans and several species of Trichophyton at low concentrations in vitro. The antibiotic is more effectvie against fungi at slightly acidic pH than neutral pH. When administered to mice through the intraperitoneal, intramuscular and oral routes MA excreted toafewper cent in the urine....
