- 1. 1H-Purin-6-amine
- [6-aminopurine; one of the 5 major bases (with guanine, thymine, cytosine, and uracil) found in nucleic acids. ( CSP )] (UMLS (NCI) C0001407) =Nucleic Acid, Nucleoside, or Nucleotide; Biologically Active Substance ;
| - 5. 1H-Purine-2,6-dione, 7-(2,3-dihydroxypropyl)-3,7-dihydro-1,3-dimethyl
- [A xanthine derivative. Dyphilline exerts bronchodilator effects and to a lesser extent vasodilator and diuretic properties. Dyphilline probably acts as a competitive inhibitor of phosphodiesterase which leads to an increase in intracellular cAMP. This results in relaxation of bronchial smooth muscle and other smooth muscles. Dyphylline may also antagonize adenosine receptors. Dyphylline is used in the treatment of acute bronchial asthma, chronic bronchitis and emphysema.

- 2. 1H-Purin-6-amine, 2-fluoro- (9CI)
- [A fluorinated heterocyclic 2-ring compound. 2-fluoroadenine is the base moiety for many carbocyclic and acyclic nucleoside analogues, which may be used in antineoplastic studies. ( NCI )] (UMLS (NCI) C0046110) =Nucleic Acid, Nucleoside, or Nucleotide
| - 6. 6H-Purine-6-thione, 2-amino-9-(2-deoxy-.alpha.-D-erythro-pentofuranosyl)-1,9-dihydro- (9CI)
- [A purine analog with potential antineoplastic activity. (NCI04) ( NCI )] (UMLS (NCI) C0051299) =Nucleic Acid, Nucleoside, or Nucleotide; Pharmacologic Substance ;
|
- 3. 1H-Purine-2,6-diamine
- [One of a number of organic compounds that share a similar purine structure and possess antiviral and antitumor properties. 2,6-Diaminopurine nucleosides are versatile synthetic precursors for specific N-6 modifications of antiviral and antitumor agents. (NCI04) ( NCI )] (UMLS (NCI) C0045587) =Nucleic Acid, Nucleoside, or Nucleotide; Pharmacologic Substance ;
| - 7. 9H-Purine-9-acetaldehyde, .alpha.-(1-formyl-2-hydroxyethoxy)-1,6-dihydro-6-oxo-, (R-(R*, R*))- (9CI)
- [A toxic purine analogue. Inosine dialdehyde inhibits ribonucleotide reductase, resulting in decreased synthesis of DNA, RNA, and proteins, and G2/M-phase cell cycle arrest. This agent also forms stable covalent crosslinks in proteins, thereby inhibiting the activity of enzymes involved in nucleic acid synthesis. (NCI04) ( NCI )] (UMLS (NCI) C0063555) =Organic Chemical; Pharmacologic Substance ;
|
- 4. 1H-Purine-2,6-dione, 3,7-dihydro-1,3-dimethyl-, compound with 1,2-Ethanediamine(2:1)
- [drug combination that contains theophylline and ethylenediamine; its most common use is in bronchial asthma, but it has been investigated for several other applications. ( CSP )] (UMLS (NCI) C0002575) =Organic Chemical; Pharmacologic Substance
