Decilonitrose and 4-O-succinyl-L-diginose, sugar components of decilorubicin.
Sir: Decilorubicin,l) a new anthracycline antibiotic produced by Streptomyces virginiae MF-266-g4 yields three kinds of sugars on hydrolysis. As reported in a previous paper,') hydrogenolysis of decilorubicin methyl ester gave rhodosamine. Two other sugar components have been obtained as their methyl glycosides by methanolysis of decilorubicin. One of them, a new nitro sugar is named decilonitr...
متن کاملViriplanin A, a new anthracycline antibiotic of the nogalamycin group. II. The structure of a novel hydroxyamino sugar from reduced viriplanin A.
Methyl 2,3,6-trideoxy-3-hydroxyamino-3-C-methyl-alpha-D-ribo-hexopyranoside+ ++ (2) and the corresponding amino sugar (4) were isolated from reduced viriplanin A by acidic methanolysis and esterified to the di-p-bromobenzoates (3 and 5), respectively. The absolute configuration of crystalline 3 was determined by X-ray analysis to be alpha-D. This result could be confirmed by oxidation of 2 to m...
متن کاملthe effect of consciousness raising (c-r) on the reduction of translational errors: a case study
در دوره های آموزش ترجمه استادان بیشتر سعی دارند دانشجویان را با انواع متون آشنا سازند، درحالی که کمتر به خطاهای مکرر آنان در متن ترجمه شده می پردازند. اهمیت تحقیق حاضر مبنی بر ارتکاب مکرر خطاهای ترجمانی حتی بعد از گذراندن دوره های تخصصی ترجمه از سوی دانشجویان است. هدف از آن تاکید بر خطاهای رایج میان دانشجویان مترجمی و کاهش این خطاها با افزایش آگاهی و هوشیاری دانشجویان از بروز آنها است.از آنجا ک...
15 صفحه اولAbsolute configuration of methyl isoeichlerialactone
The title compound, C(28)H(44)O(4)·0.56H(2)O, is a co-crystal of methyl isoeichlerialactone monohydrate as the major component and methyl isoeichlerialactone as the minor component in a 0.55778 (3):0.44222 (3) ratio. The conformations of both components are identical except for that of the -COOCH(3) group of the methyl propanoate side chain on the cyclo-hexane ring which is positionally disorde...
متن کاملThe absolute configuration of ( )-3-hydroxy-a-calacorene
3-Hydroxy-a-calacorene was identified in extracts from cold-shocked seedlings of cotton (Gossypium hirsutum L.) and kenaf (Hibiscus cannabinus L.), both of which are members of the Malvaceae family. ( )-3-Hydroxy-a-calacorene was isolated from Heterotheca inuloides Cass. (Asteraceae). HPLC on a chiral stationary phase column showed that the 3-hydroxy-acalacorene from cotton and kenaf had the sa...
