NM441 is a prodrug of the new quinolone carboxylic acid antibacterial agent NM394. A rat serum enzyme (NM441-hydrolase) that catalyzes the hydrolysis of NM441 to NM394 was purified by ultracentrifugation, heparin-Sepharose column chromatography, and HPLC with a Mono Q anion exchange column. The enzyme showed a single protein band after sodium dodecyl(More)
OBJECTIVES This is the first phase II study to evaluate the efficacy and tolerability of the first-line FOLFIRI, as well as the influence of uridine diphosphate glucuronosyl transferase 1, family polypeptide A1 gene (UGT1A1) 28/6 polymorphism, in Japanese metastatic colorectal cancer patients. METHODS Fifty-two patients were enrolled in this study and(More)
UNLABELLED Retrospective studies have suggested that UDP-glucuronosyltransferase (UGT)1A1, UGT1A7, and UGT1A9 predict severe toxicity and efficacy of irinotecan-containing regimens. We prospectively evaluated the impact of UGT1A genotypes and haplotypes on severe toxicity and efficacy in patients treated with fluorouracil, leucovorin, and irinotecan(More)
BACKGROUND To investigate the associations between serum concentrations of carotenoids and the presence of colorectal polyps and cancers in Japanese using a cross-sectional study. METHODS 893 subjects who underwent colorectal endoscopy between 2001 and 2002 provided serum samples and information on lifestyle factors. Serum concentrations of six(More)
BACKGROUND Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder comprising abdominal pain, abdominal discomfort, and disordered defecation. The prevalence of IBS is 10-15% in the general population. This study investigated the prevalence of IBS and the relationship between IBS and stress, lifestyle, and dietary habits among nursing and(More)
OBJECTIVE In Japan, there had been no prospective clinical studies conducted in terms of modified FOLFOX6 + bevacizumab therapy. We performed a post-marketing Phase II multicenter clinical study to examine the efficacy and safety of this regimen as first-line therapy for Japanese patients with advanced/recurrent colorectal cancer. METHODS Bevacizumab (5(More)
Sesamin is a major lignan constituent of sesame and possesses multiple functions such as antihypertensive, cholesterol-lowering, lipid-lowering and anticancer activities. Several groups have previously reported that sesamin induces growth inhibition in human cancer cells. However, the nature of this growth inhibitory mechanism remains unknown. The authors(More)
BACKGROUND Patients with ulcerative colitis (UC) have elevated/activated myeloid lineage leucocytes and may respond favorably to adsorptive granulocyte/monocyte apheresis (GMA). However, there are patients who respond well to GMA, and patients who do not benefit. Therefore, predictive factors of GMA efficacy need to be defined. METHODS In a prospective(More)
AIM This is a multicenter phase II study to assess the efficacy and toxicity of FOLFIRI treatment agents in full and the influence of UGT1A1*28 polymorphism in Japanese patients with advanced/metastatic colorectal cancer (mCRC). PATIENTS AND METHODS Fifty patients with mCRC participated in this study. Treatment consisted of FOLFIRI (irinotecan; 150(More)
The safety and pharmacokinetics of NM441, a prodrug of a new thiazeto-quinoline carboxylic acid derivative, NM394, were evaluated in healthy male volunteers given the drug orally in single doses of 20, 50, 100, 200, and 400 mg, and multiple doses of 300 mg twice daily for 6.5 days. No remarkable abnormalities were observed in symptoms, physical tests,(More)
