The catalytic site of muscle glycogen phosphorylase ... -
3 '-Axial CH2OH Substitution on Glucopyranose does not Increase Glycogen Phosphorylase Inhibitory Potency. QM/MM-PBSA Calculations Suggest Why
Manta, S.; Xipnitou, A.; Kiritsis, C.; Kantsadi, A. L.; Hayes, J. M.; Skamnaki, V. T.; Lamprakis, C.; Kontou, M.; Zoumpoulakis, P.; Zographos, S. E.; Leonidas, D. D.; Komiotis, D. (2012)Glycogen phosphorylase is a molecular target for the design of potential hypoglycemic agents. Structure-based design pinpointed that the 3'-position of glucopyranose equipped with a suitable group has the potential to form ... -
The binding of C5-alkynyl and alkylfurano 2,3-d pyrimidine glucopyranonucleosides to glycogen phosphorylase b: Synthesis, biochemical and biological assessment
Kantsadi, A. L.; Manta, S.; Psarra, A. M. G.; Dimopoulou, A.; Kiritsis, C.; Parmenopoulou, V.; Skamnaki, V. T.; Zoumpoulakis, P.; Zographos, S. E.; Leonidas, D. D.; Komiotis, D. (2012)C5-alkynyl and allcylfurano[2,3-d]pyrimidine glucopyranonucleosides have been synthesized and studied as inhibitors of glycogen phosphorylase b (GPb). Kinetic experiments have shown that most of these compounds were low ... -
Biochemical and biological assessment of the inhibitory potency of extracts from vinification byproducts of Vitis vinifera extracts against glycogen phosphorylase
Kantsadi, A. L.; Apostolou, A.; Theofanous, S.; Stravodimos, G. A.; Kyriakis, E.; Gorgogietas, V. A.; Chatzileontiadou, D. S. M.; Pegiou, K.; Skamnaki, V. T.; Stagos, D.; Kouretas, D.; Psarra, A. M. G.; Haroutounian, S. A.; Leonidas, D. D. (2014)The inhibitory potency of thirteen polyphenolic extracts obtained from vinification byproducts of Greek varieties of Vitis vinifera against glycogen phosphorylase (GP) has been studied by kinetic experiments. GP is an ... -
An evaluation of indirubin analogues as phosphorylase kinase inhibitors
Begum, J.; Skamnaki, V. T.; Moffatt, C.; Bischler, N.; Sarrou, J.; Skaltsounis, A. L.; Leonidas, D. D.; Oikonomakos, N. G.; Hayes, J. M. (2015)Phosphorylase kinase (PhK) has been linked with a number of conditions such as glycogen storage diseases, psoriasis, type 2 diabetes and more recently, cancer (Camus et al., 2012 [6]). However, with few reported structural ... -
Molecular Cloning, Carbohydrate Specificity and the Crystal Structure of Two Sclerotium rolfsii Lectin Variants
Peppa, V. I.; Venkat, H.; Kantsadi, A. L.; Inamdar, S. R.; Bhat, G. G.; Eligar, S.; Shivanand, A.; Chachadi, V. B.; Satisha, G. J.; Swamy, B. M.; Skamnaki, V. T.; Zographos, S. E.; Leonidas, D. D.

SRL displays specificity for TF antigen (Gal13GalNAc--Ser//Thr) expressed in all cancer types ... -
Natural flavonoids as antidiabetic agents. The binding of gallic and ellagic acids to glycogen phosphorylase b
Kyriakis, E.; Stravodimos, G. A.; Kantsadi, A. L.; Chatzileontiadou, D. S. M.; Skamnaki, V. T.; Leonidas, D. D.
