16834198-6	2005	Transition state theory calculations of 298 K rate constants in the gas phase, including quantum tunnel corrections, indicate the branching ratios for H-atom additions to C-8, C-2, N-3, N-1, and N-7 positions in adenine as 0.68, 0.20, 0.08, 0.03, and 0.01, respectively.	Adenine	212-219	homeobox C8	Homo sapiens	171-174	
11073587-1	2000	The synthesis of 12 analogues of adenine substituted at C-8 by an omega-hydroxyalkyl, omega-hydroxyalk-1-enyl, or omega-hydroxyalk-1-ynyl chain of various length has been carried out in five or six steps starting from adenine.	Adenine	33-40	homeobox C8	Homo sapiens	56-59	
11073587-4	2000	It was prepared regiospecificaly in two steps from adenine and was amenable to C-8 iodination under basic conditions and to subsequent introduction of the various carbon chains at C-8 by palladium-catalyzed cross-coupling reactions (Stille or Sonogashira).

7827031-10	1995	4,6-Diamino-5-formamidopyrimidine and 2,6-diamino-4-hydroxy-5-formamidopyrimidine may be produced by hydration of adenine and guanine, respectively, across the N(7)-C(8) double bond by mechanisms similar to those proposed previously for well-known formation of pyrimidine hydrates with the hydroxyl group located at C(6).	Adenine	114-121	homeobox C8	Homo sapiens	165-169	
6289905-1	1982	Two derivatives of NAD+ spin-labeled at N6 or C-8 of the adenine ring have been shown previously to be active coenzymes of glyceraldehyde-3-phosphate dehydrogenase (D-glyceraldehyde-3-phosphate: NAD+ oxidoreductase (phosphorylating), EC 1.2.1.12).	Adenine	57-64	homeobox C8	Homo sapiens	46-49	
6095915-3	1984	In the present study, two derivatives of NAD, spin-labeled either at N-6 or C-8 of the adenine ring, were found to be active as coenzyme.	Adenine	87-94	homeobox C8	Homo sapiens	76-79

2356124-0	1990	Oligonucleotides, part 5+: synthesis and fluorescence studies of DNA oligomers d(AT)5 containing adenines covalently linked at C-8 with dansyl fluorophore.	Adenine	97-105	homeobox C8	Homo sapiens	127-130	
2356124-1	1990	The synthesis of oligodeoxynucleotides d(AT)5 in which specific adenines are linked at C-8 position with dansyl fluorophores via a variable polymethylene spacer chain are reported.	Adenine	64-72	homeobox C8	Homo sapiens	87-90	
689031-7	1978	NAD+ immobilized on agarose through the C-8 of the adenine ring is a superior substrate compared with NAD+ linked to agarose via its periodate-oxidized ribose moieties.	Adenine	51-58	homeobox C8	Homo sapiens	40-43
