Abstract
SUMMARYDeazaguanine modifications play multifaceted roles in the molecular biology of DNA and tRNA, shaping diverse yet essential biological processes, including the nuanced fine-tuning of translation efficiency and the intricate modulation of codon-anticodon interactions. Beyond their roles in translation, deazaguanine modifications contribute to cellular stress resistance, self-nonself discrimination mechanisms, and host evasion defenses, directly modulating the adaptability of living organisms. Deazaguanine moieties extend beyond nucleic acid modifications, manifesting in the structural diversity of biologically active natural products. Their roles in fundamental cellular processes and their presence in biologically active natural products underscore their versatility and pivotal contributions to the intricate web of molecular interactions within living organisms. Here, we discuss the current understanding of the biosynthesis and multifaceted functions of deazaguanines, shedding light on their diverse and dynamic roles in the molecular landscape of life.

Abstract
Pyrrolopyrimidine containing compounds, also known as 7-deazapurines, are a collection of purine-based metabolites that have been isolated from a variety of biological sources and have diverse functions which range from secondary metabolism to RNA modification. To date, nearly 35 compounds with the common 7-deazapurine core structure have been described. This article will illustrate the structural diversity of these compounds and review the current state of knowledge on the biosynthetic pathways that give rise to them.

Abstract
Guanosine is shown to potentiate markedly the antiproliferative effect of cytosine-beta-D-arabinoside (ara-C) on B16 F10 mouse and SKMEL-28 human melanoma cell lines. Several metabolic consequences of the synergistic interaction between ara-C and guanosine on cell growth were determined in B16 F10 mouse melanoma cells. Treatment of the cells with guanosine for 24 hr resulted in an increase in the percentage of cells in the S phase of the cell cycle, a threefold increase in intracellular GTP concentration, and an increase in the incorporation of ara-C into acid-insoluble material and phosphorylated metabolites. These findings suggest that guanosine potentiates the growth-inhibitory effect of ara-C in B16 F10 melanoma cells by increasing the intracellular concentration of its active metabolites.
