Abstract A novel antitumor bicyclic depsipeptide, FR901228, was isolated from a broth culture of Chromobacterium violaceum No. 968 as colorless prisms and the molecular formula was determined as C 24 H 36 N 4 O 6 S 2., titumor effects on several humansolid tumors. Its antitumor activity against A549 humanlung adenocarcinoma was stronger than th. se of vinblastine, doxorubicin and cisplatin. These results suggest that FR900840., Yokoyama S, Watanabe T, Murao T, Ishikura H, Yamaizumi Z, Nishimura S and Miyazawa T 1985 Molecular mechanism of codon recognition by tRNA species with modified uridine in the first position of the anticodon; Proc. Natl. Acad. Sci. USA 82 4905–4909, Conclusions: This study showed that the natural course of unruptured cerebral aneurysms varies according to the size, location, and shape of the aneurysm. (Funded by the Ministry of Health, Labor, and Welfare in Japan and others; UCAS Japan UMIN-CTR number, C000000418.)., This study aimed to assess the effect of daily intake of a commercially available vegetable juice on nutritional status and metabolic syndrome-related markers in healthy young adults. Fifty-one healthy adults (14 men, 37 women), age 20 - 22 years were recruited, and their food and nutritional intake was surveyed using an FFQ based on Food Groups., In recent years, antibacterial research has increasingly relied on smaller companies or academic research institutions, which mostly have only limited financial resources, to carry a drug discovery and development process from the beginning and through to the beginning of clinical phases..
