The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 5-Amino-1-(2-bromophenyl)-1H-pyrazole-4-carbonitrile, is researched, Molecular C10H7BrN4, CAS is 71856-54-7, about Synthesis and adenosine receptor affinity of a series of pyrazolo[3,4-d]pyrimidine analogs of 1-methylisoguanosine, the main research direction is methylisoguanosine analog pyrazolopyrimidine; aminoalkylarylpyrazolopyrimidinone preparation adenosine receptor affinity.Name: 5-Amino-1-(2-bromophenyl)-1H-pyrazole-4-carbonitrile.
Two series of pyrazolo[3,4-d]pyrimidine analogs I (R = Ph, substituted Ph; R1 = Me; R = Ph, R1 = Et, Pr, Bu, Ph; R = 3-ClC6H4, R1 = Et, Pr, Bu) of 1-methylisoguanosine have been synthesized. All I were tested for A1 adenosine receptor affinity by using a (R)-{3H}-N6-(phenylisopropyl)adenosine binding assay. The 3-chlorophenyl group showed the greatest activity in the N1-position and the Bu group produced the greatest activity in the N5-position. Combination of the best substituent in each of these positions enhanced the overall activity. The most potent compound was I (R = 3-C6H4Cl, R1 = Bu) (II) with an IC50 of 6.4 × 10-6M. Selectivity at the receptor subclasses was examined by performing an A2 adenosine receptor affinity assay with [3H]CGS 21680. This series of compounds were slightly less potent at A2 receptors. II was the most potent compound with an IC50 of 19.2 × 10-6M.
