  New Substituted 1,4-Benzoxazine Derivatives with Potential Intracellular Calcium Activity

  摘要：

  Substituted 1,4-benzoxazines bearing an amino side chain at the 2-position were prepared and were found to have a moderate activity on intracellular calcium. Of the compounds studied it was found that those which possess a homoveratrylamino moiety exhibited superior potency. The chain length and the nature of the amine (4-fluorophenylpiperazine, 4-fluorobenzhydryloxyethylamine, N-substituted homoveratrylamine) is discussed. The 4-benzyl-3,4-dihydro-2[3-[[2-(3,4-dimethoxyphenyl)ethyl]amino]propyl]-2H-1,4-benzoxazine (3c) is the most potent derivative of the series with a ratio of IC50 values against PE (phenylephrine) and K+ of 2.1. Under these test conditions a ratio near 1 indicates potential intracellular calcium activity while a ratio greater than 100 an action on extracellular calcium influx.
