kristallisierter Derivate isoliertes amorphes Bufogenin aus Ch'an Su wird der Name Resibufogenin vorgeschlagen. – Die Bereitung von reinem, amorphem Resibufogenin aus dem kristallisierten Hydrochlorid wird beschrieben, ebenso der oxydative Abbau von kristallisiertem Resibufogenin-acetat. Die bisherigen Ergebnisse lassen vermuten, dass von den 4 Sauerstoffatomen des Resibufogenins (C24H32O4) zwei im Cumalinring
瑞舒非生成素的名称被提议用于Ch'an Su的非晶形富博生成素,以前被称为“异丁法林”,迄今为止仅以结晶衍生物的形式被分离出来。-描述了由结晶的盐酸盐制备纯的,无定形的瑞波夫原素的方法,以及结晶的乙酸瑞波夫原素乙酸盐的氧化降解。迄今的结果表明,瑞波夫菌素(C 24 H 32 O 4)的4个氧原子中有2个在cumalin环中,一个为仲HO基团,第四个为氧化环。

On thc basis of new degradation work it is shown that Resibufogenin is 3β-hydroxy-14β,15β-oxido-bufadien-(20; 22)-olide. It can easily be isomerized into 15-ketosteroids (Coprostane type!), which are more stable in the C/D-cis-junction.
The present invention relates to an inhibitor of miR-671-5p for use in a method of preventing or treating fibrosis. Further, the present invention encompasses a kit comprising said inhibitor of miR-671-5p. The present invention also relates to an in vitro method for identifying a compound for preventing or treating fibrosis.
Structure–cytotoxic activity relationship for the toad poison bufadienolides
active bufadienolides were identified to provide approach to a 3D QSAR method by using Comparative Molecular Field Analysis (CoMFA) study and to correlate the steric and electrostatic fields of the molecules to their activities. A valuable model which enables prediction of their activities was obtained from the CoMFA analysis, which may be employed for the drug designs of new bufadienolide analogues
