Studies Leading to Potent, Dual Inhibitors of Bcl-2 and Bcl-xL
摘要:
Overexpression of the antiapototic proteins Bcl-2 and Bcl-xL provides a common mechanism through which cancer cells gain a survival advantage and become resistant to conventional chemotherapy. Inhibition of these prosurvival proteins is an attractive strategy for cancer therapy. We recently described the discovery of a selective Bcl-xL antagonist that potentiates the antitumor activity of chemotherapy and radiation. Here we describe the use of structure-guided design to exploit a deep hydrophobic binding pocket on the surface of these proteins to develop the first dual, subnanomolar inhibitors of Bcl-xL and Bcl-2. This study culminated in the identification of 2, which exhibited EC50 values of 8 nM and 30 nM in Bcl-2 and Bcl-xL dependent cells, respectively. Compound 2 demonstrated single agent efficacy against human follicular lymphoma cell lines that overexpress Bcl-2, and efficacy in a murine xenograft model of lymphoma when given both as a single agent and in combination with etoposide.

(omega- aminoalkoxy )stilbene derivatives has been synthesized and screened for anticonvulsantactivity. The effect of structural modification of these molecules on the activities has been systematically examined. Potent anticonvulsantactivity was displayed by 2-[4-(4-methyl-1 piperazinyl)butoxy]stilbene (20) and some2-[4-(3-alkoxy-1-piperidino)butoxy]stilbene derivatives (21, 37, 38, and 40), as determined
Substituted 3-amino-2-benzyl-1-phenlypropane derivatives, methods for preparing them, pharmaceutical compositions containing them, and methods of using them to treat various medical conditions.
