权利人:GPC BIOTECH INC
摘要:The present invention relates to novel compositions of methotrexate-containing heterodimeric probe molecules, also known as chemical inducers of dimerization (CID), useful in three-hybrid assays. The invention further relates to synthesis of said compositions and their intermediates. Another aspect of the invention is a method for using the heterodimeric probe molecules described herein in drug screens to identify potential protein targets to a given ligand, optimize protein-ligand interactions, or identify potential ligands for a given protein target. In certain embodiments, the invention contemplates the synthesis of the following methotrexate-containing heterodimeric probe:

摘要:The rapid deconvolution of complex chemical mixtures, such as combinatorial libraries prepared via solution-phase simultaneous addition of functionalities is demonstrated using HPLC. Libraries containing 25-216 members were screened for biological activity and active libraries are fractionated into discreet pools using preferred reversed-phase HPLC. The entire process can be completed from a single synthesis of 15-50 mg, without the need for fixed positions, serial synthesis, or tagging.

标 题:Synthesis and use of β-lapachone analogs

摘要:3-Substituted-β-lapachone analogs and their use either alone or to augment chemotherapy or radiotherapy to induce programmed neoplastic cell death without exhibiting toxicity to surrounding normal cells are disclosed. In particular, 3-allyl-β-lapachones, 3-alkyl-β-lapachones and 3-halo-β-lapachones were found to be Topoisomerase (Topo I) inhibitors. When these analogs are used alone there is a reversible single-strand break in the DNA of neoplastic cells causing apoptosis and cell death in some cells. However, when these analogs are combined with chemotherapy or X-irradiation, an irreversible Topo I-mediated break is achieved. A new and more efficient chemical synthesis of the compounds is also disclosed.

摘要:Field of application: The invention relates to chemistry, pharmacy and cosmetology, allows to synthesize of supramolecular structure on base antibiotics derivatives for use in pharmacy, cosmetology and pharmacy. n The essence of the invention: a new derivatives of antibiotics based on supramolecular structures and a method for their preparation, characterized in that the supramolecular structures are obtained by combinatorial synthesis of an antibiotic from one source molecule with two or more groups available in the reaction for covalent modification, at least with two different modifiers simultaneously, this creates a mixture of modified derivatives of the original molecule, with a maximum variety of derivatives with forming new supramolecular structure, and as biologically active substances to create pharmaceutical compositions use such supramolecular structure without separation into individual components, and in the reaction a combinatorial mixture of modified derivatives of the original molecule is formed antibiotic, the maximum number of combinations. n Technical result: modified combinatorial derivatives of antibiotics with antimicrobial and antifungal activity against multiresistant and pan drug resistance strains of microorganisms and fungi. Means have a wide spectrum of action, and the supramolecular and combinatorial structure of their tens and hundreds of derivatives eliminates the resistance of microorganisms.
