    • The present invention provides a screen which utilises a direct biochemical interaction between moieties to determine whether or not a potential therapeutic compound (PTC) may be useful as a drug. It will be particularly useful in combinatorial approaches to drug design and testing. The screen of the invention allows determination of the binding ability of a PTC with the three amino acid motif of a decapeptide within the C epsilon 4 region of IgE, or a similar amino acid motif. Any such binding should be indicative of a potential therapeutic effect. The screen comprises: (i) a binding compound which includes a recognition site and a binding site having the sequence of amino acid residues Xaa1-Xaa2-Xaa3; and (ii) a mono or polyclonal wholly, semi- or non-synthetic antibody or fragment thereof (A1) which is able to bind selectively to the binding site; wherein Xaa1 and Xaa3 are the same or different positively charged amino acid residues such as Lys, Arg or His, preferably Lys or Arg, most preferably Lys; and Xaa2 is any other amino acid residue, preferably a neutrally charged amino acid residue, more preferably Thr, Pro, Gly or Ala, most preferably Thr.
    • 本发明提供一种利用部分之间的直接生物化学相互作用来确定潜在的治疗化合物(PTC)是否可用作药物的筛选。 在药物设计和测试的组合方法中将特别有用。 本发明的筛选允许确定PTC与IgE的Cε4区域内的十肽的三个氨基酸基序或相似的氨基酸基序的结合能力。 任何此类结合应指示潜在的治疗效果。 筛选包括:(i)包含识别位点和具有氨基酸残基Xaa1-Xaa2-Xaa3序列的结合位点的结合化合物; 和(ii)能够选择性结合结合位点的单克隆或多克隆全抗体或非合成抗体或其片段(A1); 其中Xaa1和Xaa3是相同或不同的带正电荷的氨基酸残基,例如Lys,Arg或His,优选Lys或Arg,最优选Lys; 并且Xaa2是任何其它氨基酸残基,优选中性带电荷的氨基酸残基,更优选Thr,Pro,Gly或Ala,最优选Thr。
