Dedicated to Professor Richard Schmidt for his seminal contributions to glycoside synthesis Abstract Adopting the ‘remote activation concept’ toward stereocontrolled glycoside synthesis with minimal use of protection groups, a general synthesis of phenolic 1,2-cis glycopyranosides is reported, as exemplified by aryl α-d-galacto-, α-d-gluco- and 2-azido α-d-glucopyranosides among others using glycosyl

The present invention is related to novel 21-hydroxy-6,19-oxidoprogesterone (21OH-6OP) analogues, their use as antiglucocorticoids for the treatment and/or prophylaxis of diseases associated to an excess of glucocorticoids. In particular, the invention relates to the use of novel 21-hydroxy-6,19-oxidoprogesterone (21OH-6OP) analogues having the formula FORMULAwherein X is S, SO and SO2, and R is either M or OH, for treating Cushing's syndrome, iatrogenic hypercortisolism or depression. Also the present invention is related to methods of preparing the novel 21-hydroxy-6,19-oxidoprogesterone (21OH-6OP) analogues.

A method for detecting one or more microorganisms or polynucleotide sequences from eukaroytic sources in a nucleic acid-containing test sample comprising
(a) preparing a test sample comprising labeling the nucleic acids in the test sample,
(b) preparing one or more process by immobilizing a single-stranded nucleic acid of one or more known microorganisms or sequences from eukaroytic sources,
(c) contacting, under hybridization conditions, the labeled single-stranded nucleic acid to form hybridized labeled nucleic acids, and
(d) assaying for the hybridized nucleic acids by detecting the label. The method can be used to detect genetic disorders, e.g., sickle-cell anemia.
A method for detecting (i) one or more microorganisms or (ii) nucleic acid sequences from a prokaryotic source or an eukaryotic source in a nucleic acid-containing test sample comprising
(a) labeling the nucleic acids in the test sample,
(b) contacting, under hybridization conditions, the labeled hybridizable nucleic acid and one or more immobilized hybridizable nucleic acid probes comprising (i) one or more known microorganisms or (ii) sequences from eukaroytic or prokaryotic sources, to form hybridized labeled nucleic acids, and
(d) assaying for the hybridized nucleic acids by detecting the label. The method can be used to detect genetic disorders, e.g., sickle-cell anemia.
一种检测含核酸检测样本中 (i) 一种或多种微生物或 (ii) 来自原核生物源或真核生物源的核酸序列的方法,包括
(a) 标记测试样本中的核酸、
(b) 在杂交条件下,将标记的可杂交核酸与一个或多个固定的可杂交核酸探针(包括 (i) 一个或多个已知微生物或 (ii) 来自真核或原核来源的序列)接触,以形成杂交标记核酸,和 (c) 在杂交条件下,将标记的可杂交核酸与一个或多个固定的可杂交核酸探针(包括 (i) 一个或多个已知微生物或 (ii) 来自真核或原核来源的序列)接触,以形成杂交标记核酸,和
(d) 通过检测标记对杂交核酸进行检测。该方法可用于检测遗传疾病,如镰状细胞性贫血。
