„γ‐Lactonisierte”︁ Neuroleptika vom Diphenylbutylpiperidin‐Typ (3a,b,d,4a‐d) erhält man durch Addition der Piperidine 15a‐d an die Methylenlactone 8, 14a. 8 ist ringsynthetisch oder ‐ wie auch 14 ‐ aus dem entspr. α‐Carboxylacton zugänglich. Aus den 1H‐ und 13C‐NMR‐Daten ergibt sich eine equatoriale Stellung der Aminomethylgruppe in allen Derivaten von 3 und 4. In 4a‐d wird eine bisequatorial‐trans‐ständige
STATs are transcription factors acting as intracellular signaling after stimulation with cytokines, growth factors and hormones. STAT5 is also constitutively active in many forms of cancers, including chronic myelogenous leukemia, acute lymphoblastic leukemia and Hodgkin's lymphoma. Recently, literature reported that the neuroleptic drug pimozide inhibits STAT5 phosphorylation inducing apoptosis in CML cells. We undertook an investigation from pimozide structure, obtaining simple derivatives with cytotoxic and STAT5-inhibitory activity, two of them markedly more potent than pimozide.
