After organ transplantation, severe osteoporosis is occasionally seen, and the use of immunosuppressants is thought to be one of the causes of such osteoporosis. In the present study, we investigated the effects of FK506 monotherapy on bones and determined the mechanism of onset of osteoporosis, both by assessing chronological changes in bone metabolism and(More)
We synthesized 9alpha-fluoromedroxyprogesterone acetate (FMPA) in order to test whether it is a more potent anti-angiogenic agent than medroxyprogesterone acetate (MPA), which has been widely used as a therapeutic agent for breast and endometrium cancers. FMPA was previously synthesized in 10 steps (total yield: 1%). An efficient synthesis of FMPA has been(More)
Quercetin is ubiquitously distributed in plant foods. This antioxidative polyphenol is mostly converted to conjugated metabolites in the body. Parkinson disease (PD) has been suggested to be related to oxidative stress derived from abnormal dopaminergic activity. We evaluated if dietary quercetin contributes to the antioxidant network in the central nervous(More)
Medroxyprogesterone acetate (MPA) is currently used therapeutically in the treatment of mammary and endometrial carcinomas. In order to develop a more potent and useful drug, we synthesized the novel compound, 9alpha-fluoromedoroxyprogesterone acetate (FMPA), by fluorinating MPA, and we also previously reported that FMPA displays more potent anti-angiogenic(More)
BACKGROUND A consensus on the brain dysfunction(s) underlying the delusions of Alzheimer's Dementia (AD) remains to be achieved. The aim of the present study was to test the hypothesis that content-based categorization of delusional ideas manifests as dysfunction of category-specific brain regions. METHODS Fifty-nine consecutive first-visit AD outpatients(More)
9Alpha-fluoromedroxyprogesterone acetate (FMPA) is a novel synthetic analog of medroxyprogesterone acetate (MPA), widely used as therapeutic agent for breast and endometrium cancers. FMPA showed almost the same binding affinities to the progesterone and glucocorticoid receptors as MPA. In the rabbit corneal assay, FMPA, MPA and fumagillin significantly(More)
The anti-inflammatory profile of the analogues of bis(2-aminopropyl) disulfide dihydrochloride with butyl (compd. II) and phenyl (compd. III) instead of the methyl group was studied in several mouse models related to phagocyte functions. The test samples were administered 2-3 h before the inflammatory stimulation or the peak of inflammation. Subcutaneously(More)
A new anti-angiogenic agent, 17 alpha-acetoxy-9 alpha-fluoro-6 alpha-methylprogesterone (9 alpha-fluoromedoroxyprogesterone acetate [FMPA, 9] was synthetized in a 10-step sequence. FMPA (9) had about two orders of magnitude stronger anti-angiogenic activity than medroxyprogesterone acetate (MPA), as estimated in a bioassay involving chorioallantoic(More)
Propionibacterium freudenreichii ET-3 (7025) culture, a cell-free product of whey fermentation by P. freudenreichii ET-3, has been shown to promote the growth of Bifidobacteria through the action of 1,4-dihydroxy-2-naphthoic acid (DHNA). Here we report the results of two clinical studies designed to evaluate the safety of high doses of P. freudenreichii(More)
