Addition of bromine and potassium dihaloiodates((1)) to 2-alkyl-2-azabicyclo[2.2.1]hept-5-enes and 2-alkyl-2-azabicyclo[2.2.2]oct-5-enes affords quaternary ammonium salts containing the aziridine ring and the polyhalide anion. The possibility of using these salts for the synthesis of 6-substituted 2-alkyl-2-azabicyclo[2.2.1]heptanes has been shown.

The present invention is directed to synthetic bridged bicyclic compounds that are inhibitors of rho-associated protein kinase. The present invention is also directed to pharmaceutical compositions comprising such compounds and a pharmaceutically acceptable carrier. The invention is additionally directed to a method of preventing or treating diseases or conditions associated with cytoskeletal reorganization. The method comprises administering to a subject a therapeutically effective amount of a Rho kinase inhibitory compound of Formula I, wherein said amount is effective to influence the actomyosin interactions, for example, by leading to cellular relaxation and alterations in cell-substratum adhesions. In one embodiment, the method treats increased intraocular pressure, such as primary open-angle glaucoma. In another embodiment, the method treats diseases or conditions of the lung associated with excessive cell proliferation, remodeling, inflammation, vasoconstriction, bronchoconstriction, airway hyperreactivity and edema.
The 1,3-dipolarcycloaddition of nitrile oxides to 2-X-bicyclo[2.2.2]oct-5-enes (X=O, NMe, S, SO2) were investigated together with acyclic and alicyclic analogues. The regioselectivity in an exo-attack was controlled by the heteroatom present at an allylic position —a remote attack was predominant in the cases of O and SO2 but a vicinal attack in those of NMe and S— and the results were rationalized
与无环和脂环类似物一起研究了腈氧化物与 2-X-双环 [2.2.2] oct-5-烯(X=O、NMe、S、SO2)的 1,3-偶极环加成反应。外向攻击中的区域选择性受烯丙基位置上的杂原子控制——远程攻击在 O 和 SO2 的情况下占主导地位,但在 NMe 和 S 的情况下是邻位攻击——结果从电子性质中得到了合理化杂原子 X。在内向攻击中,在每种情况下都观察到远程攻击,并且 X 与氧化腈的氧之间的偶极-偶极排斥被认为是主要因素。杂原子周围的空间环境控制着面部选择性。

The present application relates to new binder-drug conjugates (ADCs) of N,N-dialkylauristatins that are directed against the target mesothelin, to active metabolites of these ADCs, to processes for preparing these ADCs, to the use of these ADCs for treating and/or preventing illnesses, and also to the use of these ADCs for producing medicaments for treating and/or preventing illnesses, more particularly hyperproliferative and/or angiogenic diseases such as, for example, cancer diseases. Such treatments may be practised as a monotherapy or else in combination with other medicaments or further therapeutic measures.
