摘要:
The invention relates to new compounds for cancer therapy or diagnosis and more specifically to the use of a non-toxic B subunit of Shiga toxin mutant as a vector for diagnostic products or drugs in over-expressing Gb3 receptor cells, such compounds having the following formula: STxB-Z(n)-Cys-Y(m)-T wherein STxB is the Shiga Toxin B subunit or a functional equivalent thereof, Z(n) wherein n is 0 or 1 and when n is 1, Z is an amino-acid residue devoid of sulfhydryl group, or is a polypeptide, Cys is the amino-acid residue for Cysteine, T is a molecule linked by a covalent bound to the S part of Cys, selected in a group comprising: agents for in vivo diagnosis, cytotoxic agents, prodrugs, or enzymes for the conversion of a prodrug to a drug, Y(m) wherein m is 0 or 1 and when m is 1, Y is a linker between T and Cys, said linker being either cleavable or not cleavable for the release of T after the internalization of the hybrid compound into said cells.

摘要:
The present invention provides chimeric polypeptides comprising a first polypeptide that binds to a component of extracellular matrix and a second polypeptide that provides for a therapeutic effect. The present invention further provides compositions, including pharmaceutical compositions, comprising a subject chimeric polypeptide. A subject chimeric polypeptide is useful in a variety of treatment, diagnostic, and research applications, which are also provided.
摘要:
This invention concerns multiple release spacers and spacer systems, which release multiple leaving groups following a single activation. It concerns compounds comprising a specifier linked to two or more of the same or different leaving groups (L in the figure) via a self-eliminating multiple release spacer or spacer system, which compounds upon a single activation step, in particular removal or transformation of the specifier, release at least two leaving groups.
摘要:
The invention relates to the use of gene therapy in the treatment of aseptic loosening of orthopaedic prostheses and discloses methods of refixing such prostheses without open revision surgery. In particular, it provides adenoviral vectors and prodrugs for simultaneous, separate or sequential use in the destruction of interface tissue allowing subsequent recementing of loose prostheses in a minimally invasive manner.
摘要:
This invention provides compounds, compositions and methods for treating cancer, infectious disease, an autoimmune disorder or an inflammatory condition. Therapeutic compounds useful in the methods of this invention are 5′-phosphoramidatyl, 1,5-substituted pyrimidine compounds, derivatives, analogs and pharmaceutically acceptable salts thereof.
摘要:
Agents are provided which are capable of inhibiting the cell division cycle in a target cell of interest. The agents comprise first and second components, wherein the first component is a targeting moiety which is capable of directing the second component to the target cell of interest. The second component is capable of inhibiting the cell division cycle in the target cell of interest. The agents are preferably provided in the form of conjugates, and the second component is preferably a cytolethal distending toxin. Methods for the preparation of the agents, and the use thereof for treating proliferative cell disorders and intracellular pathogens are also provided.
摘要:
The invention is directed to a pharmacologically active peptide conjugate having a reduced tendency towards enzymatic cleavage comprising a pharmacologically active peptide sequence (X) and a stabilizing peptide sequence (Z) of 4-20 amino acid residues covalently bound to X.
摘要:
The invention provides a kit for lectin-directed prodrug delivery comprising a prodrug and a lectin-directed glycoconjugate, wherein the glycoconjugate is adapted to cleave the prodrug and thereby release the drug. The glycoconjugate generally comprises an enzyme conjugated to a carbohydrate moiety which binds to a lectin. The invention also provides novel glycoconjugates and novel methods of synthesizing prodrugs.
