Synthesis of novel 24-amino-25,26,27-trinorlanost-8-enes: Cytotoxic and apoptotic potential in U937 cells

In the present study, the synthesis of a range of novel 24-amino-25,26,27-trinorlanost-8-ene derivatives including 24-piperadino-trinorlanost-8-enes, 24-piperazino-trinorlanost-8-enes, 24-morpholino-trinorlanost-8-enes, and 24-diethylamino-trinorlanost-8-enes is reported and their cytotoxic and apoptotic potential evaluated in U937 cell lines. Excellent IC50 results for piperidine and 1-(2-hydroxyethyl)piperazine derivatives have been observed (IC50 values of 1.9 μM and 2.7 μM in U937 cells, respectively).
