The invention provides methods and compositions for enhancing apoptosis of pathogenic cells. The general method comprises the of contacting the cells with an effective amount of an AV peptoid, wherein the AV peptoid is a peptide comprising AX
1
, wherein X
1
is V, I or L, or a peptide mimetic thereof, which interacts with an Inhibitor of Apoptosis protein (IAP) as measured by IAP binding, procaspase-3 activation or promotion of apoptosis, wherein apoptosis of the pathogenic cells is enhanced. The subject compositions encompass pharmaceutical compositions comprising a therapeutically effective amount of a subject AV peptoid in dosage form and a pharmaceutically acceptable carrier, wherein the AV peptoid is a peptide comprising AX
1
, wherein X
1
is V, I or L, or a peptide mimetic thereof, which inhibits the activity of an Inhibitor of Apoptosis protein (IAP) as measured by IAP binding, procaspase-3 activation or promotion of apoptosis. The invention also provides assays for identifying agents which modulates the interaction of an AV peptoid with an IAP, active compounds identified in such screens and their use in the foregoing compositions and therapeutic methods.
本发明提供了增强致病细胞凋亡的方法和组合物。一般方法包括将细胞与有效量的AV肽类接触,其中AV肽类是包含AX1的肽类,其中X1为V、I或L,或其肽类类似物,通过IAP结合、procaspase-3激活或促进凋亡等测量方式与凋亡抑制蛋白(IAP)相互作用,从而增强致病细胞的凋亡。所述组合物包括在制剂中含有治疗有效量的AV肽类和药学可接受的载体的制药组合物,其中AV肽类是包含AX1的肽类,其中X1为V、I或L,或其肽类类似物,通过IAP结合、procaspase-3激活或促进凋亡等测量方式抑制凋亡抑制蛋白(IAP)的活性。本发明还提供了用于识别调节AV肽类与IAP相互作用的试剂的测定方法,以及在此类筛选中鉴定出的活性化合物及其在上述组合物和治疗方法中的应用。
