  名称：

  Catechol derivatives of aminopyrazine and cell protection against uvb-induced mortality

  摘要：

  A series of 5-aryl- and 3,5-bis-aryl-7-amino- 1,4-pyrazine: derivatives 4 acid 6, and related imidazolopyrazinones 7, has been synthesized, the aryl groups of which are catechol and or phenol substituents. These compounds, tested against human keratinocyte cells stressed by UVB irradiation, showed high antioxidative properties. One compound (6f) was more active than EGCG; ECG (green tea extract) in reducing cell mortality. (C) 2001 Elsevier Science Ltd. All rights reserved.
