摘要： The present invention discloses a novel quinobenzoxazine self-assembly complex on DNA and on the topoisomerase II-DNA complex. The related model is used to design a new series of quinobenzoxazines, pyridobenzophenoxazines, pyrridonaphthophenoxazines, and other related compounds that may exhibit anticancer or antibiotic activity. The anticancer activity of these compounds is thought to operate via stabilization of the topoisomerase II-DNA complex and/or interaction with G-quadruplexes, while the antibiotic activity of these compounds derives from their ability to inhibit gyrase, the bacterial type II topoisomerase.

摘要： Compounds containing two aromatic systems covalently linked through a linker containing one or more atoms, or “linker” defined as including a covalent bond per se so as to space the aromatic systems at a distance 1.5-15 Å, are effective in treating conditions associated with bone deficits. The compounds can be administered to vertebrate subjects alone or in combination with additional agents that promote bone growth or that inhibit bone resorption. They can be screened for activity prior to administration by assessing their ability to effect the transcription of a reporter gene coupled to a promoter associated with a bone morphogenetic protein and/or their ability to stimulate calvarial growth in model animal systems.

摘要： It was found that normal human stem cells produce a regulated non-processive telomerase activity, while cancer cells produce a processive telomerase activity. Nucleotide analogs, such as 7-deaza-2′-deoxyquanosine-5′-triphosphate (7-deaza-dGTP) were found to be substrates for processive telomerase and incorporated into telomeric sequence. The incorporation of this nucleotide subsequently affected the processivity of telomerase, converting processive telomerase to non-processive telomerase. The incorporation of this nucleotide analogs was also found to inhibit formation of G-quartets by telomeric sequence. Other methods for converting cancer processive telomerase to the more benign non-processive telomerase include partially cleaving the telomerase RNA. The nucleoside analogs were found to be capable of a variety of activities including mediating allosteric-like inhibition of telomerase, premature termination and shortening of telomeric DNA, destabilization of telomeric structure and function and eventually cell death. Understanding the mechanisms of telomerase modulation by the 7-deaza-nucleotides has allowed the design of new telomerase inhibitors, modulators and agents for affecting telomere structure and function. These discoveries have application in the treatment of cancer.

摘要： Certain non-nucleoside compounds that will selectively inhibit telomerase by targeting the nucleic add structures, such as G-quadruplexes, that may be associated with human telomeres or telomerase have been identified. Inhibition of human telomerase by two perylenetetracarboxylic acid diimides and a carbocyanine has been demonstrated. 1H-NMR studies have evidenced the stabilization of a G-quadruplex by the perylenetetracarboxylic acid diimide compounds and provided evidence that these and structurally related compounds inhibit the telomerase enzyme by a mechanism consistent with interaction with G-quadruplex structures.

摘要： The present invention includes a number of structural analogues of UK-1. A comparision of the anticancer activity of the UK-1 analogues with their ability to inhibit the growth of methicillin-sensitive and methicillin-resistant Staphylococcus aureus demonstrates that a structurally simplified analogue of UK-1 retains the natural product's selective activity against cancer cells. Structurally conservative changes to UK-1 that diminish Mg2+-binding ability may result in a dramatic decrease in cancer cell cytotoxicity. The results may establish a minimum structural pharmacophore as well as a functional role for Mg2+-binding in the selective cytotoxicity of UK-1.
