This invention provides chimeric molecules that are catalytic antagonists of a target molecule. The catalytic antagonists of this invention preferably comprise a targeting moiety attached to an enzyme that degrades the molecule specifically bound by the targeting moiety. The catalytic antagonists of this invention thus bind to a target recognized by the targeting moiety (e.g., a receptor) the enzyme component of the chimera then degrades all or part of the target. This typically results in a reduction or loss of activity of the target and release of the chimeric molecule. The chimeric molecule is then free to attack and degrade another target molecule.
这项发明提供了催化拮抗剂的嵌合分子,该催化拮抗剂是目标分子的催化拮抗剂。该发明的催化拮抗剂优选包括连接到降解与靶向基团特异结合的酶的靶向基团。因此,该发明的催化拮抗剂结合到被靶向基团识别的目标(例如,受体),然后嵌合体的酶组分降解目标的全部或部分。这通常导致目标的活性减少或丧失,并释放出嵌合分子。然后,嵌合分子可以自由攻击和降解另一个目标分子。
