Abstract: The present invention relates to novel piperidine derivatives having better cell growth inhibitory activities toward cancer cell cultures and, more particularly, 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.

Abstract: The present invention concerns a new method for ex-vivo purging of cells in autologous transplantation, wherein the sample of taken cells is treated with a sufficient amount of a multimeric form of the soluble portion of FasL to kill malignant cells without substantially affecting viability of cells to be transplanted. Autologous stem cell transplantation (ASCT) following high-dose chemotherapy with or without radiotherapy has become the standard therapy for the majority of patients with large-cell lymphomas, multiple myeloma, and refractory/recidivating Hodgkin's disease. Such therapy is nowadays also contemplated for selected patients with low-grade lymphomas (chronic lymphocytic leukemia, follicular lymphoma, mantle cell lymphoma) and for patients with acute myeloid leukemia (AML). Current treatments for cell purging include chemotherapy and antibody cocktails. These treatments are often toxic on stem cells and not efficient in eliminating cancer cells.
