crystallographic analysis) is the active P450arominhibiting enantiomer of 4 and shows a rp value of 617. Compound 4 is a reversible inhibitor showing a competitive type of inhibition and a type II difference spectrum. In vitro 4 influenced other steroidogenic P450 enzymes either not at all (bovine adrenal P450 scc) or only marginally (rat testicular P45017, bovine adrenal P450 18). In ACTH-stimulated rat adrenal

Aromatase‐inhibitorischer Wirkung, wurden die Verbindungen 1‐7 synthetisiert und auf ihre Hemmaktivität gegenüber Aromatase und Desmolase unlersucht. Mit Ausnahme von Verbindung 2 zeigen alle Derivate eine stärkere Aromatase‐Hemmung als die Ausgangsverbindungen und erweisen sich auch als potentere Aromatase‐Inhibitoren als Aminoglutethimid (AG), der einzige im Handel befindliche Wirkstoff.

以黄酮和黄烷酮这两种具有弱芳香化酶抑制作用的天然产物为原料,合成了化合物1-7,并研究了它们对芳香化酶和解链酶的抑制活性。除化合物 2 外,所有衍生物均显示出比起始化合物更强的芳香化酶抑制作用,并且证明是比市场上唯一的活性成分氨基鲁米特 (AG) 更有效的芳香化酶抑制剂。与 AG 相比,化合物 1 和 3-7 没有显示出对解糖酶的抑制,这会导致 AG 出现不良副作用。
Basic Anion-Exchange Resin-Catalyzed Aldol Condensation of Aromatic Ketones with Aldehydes in Continuous Flow
A general method for the aldol condensation of aromatic ketones with aldehydes was developed under continuous-flow conditions using a commercially available, strongly basic anion-exchange resin (A26) as catalyst. This procedure, in addition to exhibiting a wide substrate scope, promoted carbon–carbon bond formation under mild conditions using a quasi-stoichiometric ratio of starting reagents with good
