Caspase-independent pathways of programmed cell death: The unraveling of new targets of cancer therapy?

Constantinou, Constantina; Papas, Konstantinos A.; Constantinou, Andreas I. (2009)

In the past few years, accumulating evidence in the literature supports the existence of pathways of caspase-independent programmed cell death (CI-PCD). These pathways are likely to be acting as 'death backup systems' that ...

Flavonoids as DNA topoisomerase antagonists and poisons: Structure-activity relationships

Constantinou, Andreas I.; Mehta, R.; Runyan, C.; Rao, K.; Vaughan, A.; Moon, R. (1995)

Selected flavonoids were tested for their ability to inhibit the catalytic activity of DNA topoisomerase (topo) I and II. Myricetin, quercetin, fisetin, and morin were found to inhibit both enzymes, while phloretin, ...

Genomic approaches that aid in the identification of transcription factor target genes

Kirmizis, Antonis; Farnham, P. J. (2004)

It is well-established that deregulation of the transcriptional activity of many different genes has been causatively linked to human diseases. In cancer, altered patterns of gene expression are often the result of the ...

Glycogen phosphorylase inhibitors: A free energy perturbation analysis of glucopyranose spirohydantoin analogues

Archontis, Georgios Z.; Watson, K. A.; Xie, Q.; Andreou, Georgia; Chrysina, Evangelia D.; Zographos, Spyros E.; Oikonomakos, Nikos G.; Karplus, M. (2005)

GP catalyzes the phosphorylation of glycogen to Glc-1-P. Because of its fundamental role in the metabolism of glycogen, GP has been the target for a systematic structure-assisted design of inhibitory compounds, which could ...

HIV-1 integrase: From biology to chemotherapeutics

Zeinalipour-Loizidou, E.; Nicolaou, Charalambos P.; Nicolaïdes, Andrew N.; Kostrikis, Leontios G. (2007)

AIDS has claimed the lives of 25 million people worldwide, an additional 40 million people are HIV-infected and new cases are being diagnosed every year. Despite the fact that HAART has moved AIDS from the category of ...

Kinetic and crystallographic studies of glucopyranose spirohydantoin and glucopyranosylamine analogs inhibitors of glycogen phosphorylase

Watson, K. A.; Chrysina, Evangelia D.; Tsitsanou, K. E.; Zographos, Spyros E.; Archontis, Georgios Z.; Fleet, G. W. J.; Oikonomakos, Nikos G. (2005)

Glycogen phosphorylase (GP) is currently exploited as a target for inhibition of hepatic glycogenolysis under high glucose conditions. Spirohydantoin of glucopyranose and N-acetyl-β-D-glucopyranosylamine have been identified ...
