The present invention relates to novel piperidine derivatives having better cell growth inhibitory activities toward PANC-1 cancer cell cultures than FK866. Accordingly, the present invention relates to compounds of formula I, wherein Ar1 is aryl or heteroaryl, which are optionally substituted by one, two or three substituents selected from lower alkyl; lower alkoxy; formyl; hydroxyl; lower alkyl substituted by lower alkoxy or hydroxyl; A is CnH2n, CnH2n-2 or CnH2n-4, wherein n=4,5,6,7; B is =N-CN, oxo (=O), thio (=S); D is NH, -CH=CH-; Ar2 is aryl or heteroaryl which are optionally substituted by one, two or three halogen substituents; wherein, if B is oxo (=O), Ar1 and Ar2 are not simultaneously phenyl and pyridine-3-yl; B and D are not simultaneously =N-CN and -CH=CH-, or a pharmaceutically acceptable salt, a racemic mixture or its corresponding enantiomers and/or optical isomers. The compounds of formula I and their pharmaceutically usable addition salts possess valuable pharmacological properties. Specifically, it has been found that the compounds of the present invention, alone or in combination with other therapeutic active compounds, have an activity as chemotherapeutic agents against pancreatic cancers.
本发明涉及新型哌啶衍生物,其对 PANC-1 癌细胞培养物的细胞生长抑制活性优于 FK866。因此,本发明涉及式 I 的化合物,其中 Ar1 是芳基或杂芳基,可任选被一个、两个或三个取代基取代,这些取代基选自低级烷基;低级烷氧基;甲酰基;羟基;被低级烷氧基或羟基取代的低级烷基;A 是 CnH2n、CnH2n-2 或 CnH2n-4,其中 n=4、5、6、7;B 是 =N-CN、氧代(=O)、硫代(=S);D是NH、-CH=CH-;Ar2是芳基或杂芳基,可任选被一个、两个或三个卤素取代基取代;其中,如果B是氧代(=O),Ar1和Ar2不同时是苯基和吡啶-3-基;B和D不同时是=N-CN和-CH=CH-,或药学上可接受的盐、外消旋混合物或其相应的对映体和/或光学异构体。式 I 化合物及其药用加成盐具有宝贵的药理特性。具体地说,已经发现本发明的化合物,单独或与其他治疗活性化合物结合,具有作为化疗剂对抗胰腺癌的活性。
