  • Patent number: 5563250
    Abstract: The present invention provides cleavable conjugates whose linkers contain a labile bond that is cleavable under a variety of mild conditions, including weakly acidic. Since the agent may be bonded directly to the linker, cleavage can result in release of native agent. The invention also provides methods for producing cleavable conjugates. Preferred agents include drugs, toxins, biological response modifiers, radiodiagnostic compounds, radiotherapeutic compounds, and derivatives thereof. The targeting molecule employed in the invention may be an intact molecule, a fragment thereof, or a functional equivalent thereof. In a particularly preferred embodiment, the targeting molecule is a monoclonal antibody directed towards a tumor-associated antigen in man. The invention further provides methods for delivering to the cytoplasm of a target cell an agent free of its targeting molecule carrier.

  • Patent number: 5166346
    Abstract: Process for the preparation of thiophene derivatives and also new dihydrothiophene 1-oxides.Thiophene derivatives having an--optionally substituted--amino group on the thiophene ring are prepared by dehydrogenating dihydrothiophenes, substituted in a manner identical to that of the desired thiophene derivatives, by means of H.sub.2 O.sub.2, the dihydrothiophenes being reacted with H.sub.2 O.sub.2 in a first reaction stage in a neutral medium to give the corresponding sulfoxides, which are then rearranged into the thiophene derivatives by means of acid in the second reaction stage.The dihydrothiophene 1-oxides formed as intermediates in this reaction are new compounds. Like the thiophene derivatives formed from them by rearrangement with acid, they are intermediates, mainly in the sector of plant protection agents and pharmaceuticals.

  • Patent number: 5145975
    Abstract: The present invention relates to the treatment of diseases caused by invading organisms in a host by first identifying an enzymatic difference between the host and the invading organism and then administering to the host a pharmaceutically effective amount of a subversive substrate for the differing enzyme of the invading organism, whereby the action of the differing enzyme causes a result counter to the intended result and function of the enzyme that results in its debilitation or death. In particular, treatment of parasitic diseases caused by kinetoplastids including trypanosomes and leishmanias, e.g., African sleeping sickness, Chagas' disease, oriental sore and kala-azar is accomplished by administration of a pharmaceutically effective antiparasitic amount of a competitive toxigenic substrate for trypanothione reductase. Methods of treatment and compositions therefor contain a competitive toxigenic substrate for trypanothione reductase. Numerous compounds and corresponding compositions are disclosed.
