Tetra-substituted naphthalene diimide (ND) derivatives with positively charged termini are potent stabilizers of human telomeric and gene promoter DNA quadruplexes and inhibit the growth of human cancer cells in vitro and in vivo. The present study reports the enhancement of the pharmacological properties of earlier ND compounds using structure-based(More)
The ECTOPICALLY PARTING CELLS 1 (EPC1) gene encodes a putative retaining glycosyltransferase of the GT64 family, and epc1-1 mutant plants have a severely dwarfed phenotype. A new mutant allele of this gene, epc1-2, has been isolated. Reduced cell adhesion that has previously been reported for the epc1-1 mutant was not observed for either the epc1-1 or(More)
The hypoxia-inducible transcription factor (HIF) co-ordinates the response of tumours to low oxygen by stimulating genes involved in metabolism and angiogenesis. HIF pathway activation is associated with decreased progression-free survival and increased mortality; compounds that target this pathway are potential agents for the treatment of a range of solid(More)
A series of naphthalene derivatives with disubstituted triazole side-arms have been assembled by click chemistry. Lead compounds show a high level of selectivity for renal, osteo- and Ewing's sarcomas that express the HIF-1α transcription factor. They also interact selectively with the quadruplex DNAs located in the promoter of the HIF genes and it is(More)
Various bis-benzimidazole derivatives have been reported to possess activity against Gram-positive pathogens. No mechanism of action has been elucidated to fully account for the antibacterial activity of this class of compounds. A group of symmetric bis-benzimidazoles (BBZ) designed as anticancer agents have previously been shown to possess moderate(More)
The symptoms of Clostridium difficile infection are mediated primarily by two toxins, TcdA and TcdB, the expression of which is governed by a multitude of factors including nutrient availability, growth phase and cell stress. Several global regulators have been implicated in the regulation of toxin expression, such as CcpA and CodY. During attempts to(More)
