    • The invention provides a method for identifying a compound which modulates the activity of a BCL-2 family polypeptide, the method comprising: a) contacting said BCL-2 family polypeptide with a compound under conditions suitable for modulation of the activity of said BCL-2 family polypeptide; and b) detecting modulation of the activity of said BCL-2 family polypeptide by the compound, wherein the compound interacts with a binding site comprising one or more of an al helix, a2 helix, a loop between al-a2, a.6 helix, and select residues of a4, a.5, and a.8 helices in said BCL-2 family polypeptide; wherein the interaction of the compound with the binding site occurs at a horizontal hydrophobic groove with or without a perimeter of charged and hydrophilic residues, a superior juxta-loop, an inferior juxta-loop, or combination thereof.
    • 本发明提供了鉴定调节BCL-2家族多肽活性的化合物的方法,所述方法包括:a)在适于调节所述BCL-2活性的条件下使所述BCL-2家族多肽与化合物接触 家族多肽; 和b)检测所述化合物对所述BCL-2家族多肽的活性的调节,其中所述化合物与包含α1螺旋,α2螺旋,α1-α2,α6螺旋之间的环中的一个或多个的结合位点相互作用 ,并选择所述BCL-2家族多肽中a4,a.5和a.8螺旋的残基; 其中所述化合物与所述结合位点的相互作用发生在具有或不具有带电和亲水残基的周界,上级并置环,下级并置环或其组合的水平疏水性凹槽处。
