    摘要: The instant invention relates to a novel method for the delivery of antitumor drugs to tumor cells by the administration of a tumor-selective antibody-.beta.-lactamase conjugate that binds to tumor cells, and the additional administration of a cephalosporin prodrug that is converted at the tumor site, in the presence of the antibody-.beta.-lactamase, to an active cytotoxic drug. According to the preferred embodiment of this invention, a cephalosporin mustard has been constructed which when cleaved by .beta.-lactamase yields a cytotoxic nitrogen mustard. The methods, antibody-enzyme conjugate, prodrugs, pharmaceutical compositions, and combinations of this invention provide for enhanced selective killing of tumor cells and are thus useful in the treatment of cancers and other tumors.

    摘要: The invention encompasses a series of tetrahydrocarboline compounds of Formula I which inhibit HIV entry by attaching to the exterior viral envelop protein gp120 and interrupting the viral entry process, possibly by interfering with the cellular receptor CD4. This action makes the compounds useful for treating HIV infection and AIDS. The invention also encompasses pharmaceutical compositions and methods for treating those infected with HIV.
