Strained Conformations of Nucleosides in Active Sites of Nucleoside Phosphorylases

open access: yesBiomolecules, 2020
Nucleoside phosphorylases catalyze the reversible phosphorolysis of nucleosides to heterocyclic bases, giving α-d-ribose-1-phosphate or α-d-2-deoxyribose-1-phosphate. These enzymes are involved in salvage pathways of nucleoside biosynthesis. The level of

Nucleoside Sensing [PDF]

open access: yesSensors, 2006
A rigid molecular clip comprising bisphosphonate binding sites and aromaticsidewalls forming an electron-rich cavity is able to distinguish between nucleosides andnucleotides in aqueous solution. Neutral nucleosides as well as antibiotics derived thereofare drawn into the unpolar interior of the cleft and lead to substantial upfield-shifts in the 1HNMR

Testicular disposition of clofarabine in rats is dependent on equilibrative nucleoside transporters

open access: yesPharmacology Research & Perspectives, 2021
Acute lymphoblastic leukemia (ALL) is the most common cancer in children and adolescents. Although the 5‐year survival rate is high, some patients respond poorly to chemotherapy or have recurrence in locations such as the testis. The blood–testis barrier

Anti-Proliferative Potential of Secondary Metabolites from the Marine Sponge Theonella sp.: Moving from Correlation toward Causation

open access: yesMetabolites, 2021
Marine sponges have been recognized as a rich source of potential anti-proliferative metabolites. Currently, there are two sponge-derived anti-cancer agents (a macrolide and a nucleoside) isolated from the Porifera phylum, suggesting the great potential ...

Phosphorylation of purine and pyrimidine nucleosides by isolated rat liver mitochondria [PDF]

open access: yes, 1975
Formation of 5'-AMP, 5'-GMP, 5'-CMP and 5'UMP was confirmed in isolated rat liver mitochondria incubated with alpha-ketoglutarate, inorganic phosphate, purine nucleoside and pyrimidine nucleoside. Increased incorporation of 32Pi into ATP, GTP and UTP was
