  A method for producing low molecular weight compounds, which are capable of binding to a naturally occurring receptor and which can be used as drugs and which mimic the three dimensional surface structure of antibodies to drug molecules, are produced by first generating a non-cross reactive antibody to a drug and then producing a low molecular weight structural mimic of the antibody.

  一种生产低分子量化合物的方法，这些化合物能够与自然存在的受体结合，可用作药物，并且模仿抗体对药物分子的三维表面结构。这些化合物首先通过生成对药物的非交叉反应性抗体，然后生产出模仿抗体的低分子量结构模拟物。
