The K‐Ras GTPase is a major target in anticancer drug discovery. However, direct interference with signaling by K‐Ras has not led to clinically useful drugs yet. Correct localization and signaling by farnesylated K‐Ras is regulated by the prenylbinding protein PDEδ. Interfering with binding of PDEδ to K‐Ras by means of small molecules provides a novel opportunity to suppress oncogenic signaling. Here
Disclosed herein are compounds having the structure of Formula I and pharmaceutically suitable salts, esters, and prodrugs thereof that are useful as antibacterially effective tricyclic gyrase inhibitors.
Related pharmaceutical compositions, uses and methods of making the compounds are also contemplated.

Die Isolierungvon 3α,17,21-Trihydroxy-5α-pregnandion-(11,20) in Form seines Di-O-acetyl-Derivates sowie von «Subst. Y» aus Rinder-Nebennieren-Extrakten wird beschrieben, ferner eine Teilsynthese des obigen Diketons aus «Subst. C» über das Di-O-formyl-Derivat. «Subst. Y» besitzt vermutlich die Formel C12H14O5, sie enthält den Isovanilloyl-Rest und ausserdem eine zweite Ketogruppe, vermutlich als primäres
3α,17,21-三羟基-5α-孕烯二酮-(11,20)的分离形式为其二-O-乙酰基衍生物和 Y“描述了来自牛肾上腺提取物的Y,此外,还部分合成了上述来自“ Subst。通过二-O-甲酰基衍生物的C。“名词 Y»的分子式为C 12 H 14 O 5,它含有异香草基残基和第二个酮基,大概是伯酮醇。描述了一些初步尝试来分离肾上腺提取物的弱极性部分。除已知物质外,它们还提供了大量无法鉴定或澄清的少量晶体。据我们所知,在已知物质中,首次从肾上腺提取物中分离出3β-羟基-5α-雄激素-(11,17)。
