guanosine

 [gwah´no-sēn]
a nucleoside, guanine riboside, one of the major constituents of RNA.
cyclic guanosine monophosphate a cyclic nucleotide, guanosine 3′,5′-cyclic monophosphate, an intracellular “second messenger” similar in action to cyclic adenosine monophosphate; the two cyclic nucleotides activate different protein kinases and usually produce opposite effects on cell function. Abbreviated 3′,5′-GMP, cGMP, and cyclic GMP.
guanosine monophosphate (GMP) a nucleotide important in metabolism and RNA synthesis.
guanosine triphosphate (GTP) a nucleotide required for RNA synthesis and involved in energy metabolism.

Neopterin (6-D-erythro-hydroxy propyl pteridine) is a catabolic product of the purine nucleotide guanosine triphosphate. Neopterin is produced in macrophages from guanosine 5'-triphosphate (GTP) which is cleaved by GTP-cyclohydrolase 1 to 7,8-dihydroneopterin triphosphate, followed by conversion of 7,8-dihydroneopterin triphosphate to neopterin and 7,8-dihydroneopterin under the influence of phosphatases.
Although the precise mechanism of action is not fully known, the antimonials are known to inhibit glycotic enzymes and fatty acid oxidation in leishmania amastigotes, and there is a dose dependent inhibition in net formation of adenosine triphosphate (ATP) and guanosine triphosphate (GTP) (3).
They're disorders that roll off the tongue like succinic semialdehyde dehydrogenase deficiency, guanosine triphosphate cyclohydrolase I deficiency, and aromatic Lamino acid decarobxylase deficiency.
Nitric oxide binds to the haem moiety of guanylate cyclase and increases its activity by 400-fold, catalyzing the conversion of guanosine triphosphate to cyclic guanosine monophosphate (cGMP).
These diverse effects result in a marked reduction of intracellular guanosine triphosphate pools and inhibition of viral RNA and protein synthesis.
Farnesyl pyrophosphate (FPP) is required for the activation of small guanosine triphosphate (GTP) binding regulatory proteins.
