The structures of stachybocins A, B and C, new endothelin receptor antagonist, were determined by NMR spectral analysis using pulse-field-gradient technique. Stachybocin A consists of two spirobenzofuran units each fused to a substituted decalin, which were connected by a lysine residue. Stachybocins B and C are derivatives of stachybocin A with an additional hydroxy group at the same position in the different decalin unit.
新型内皮素受体拮抗剂水苏糖素A、B和C的结构通过使用脉冲场梯度技术的核磁共振光谱分析得以确定。水苏糖素A由两个分别与一个取代十氢化萘稠合的螺苯并呋喃单元组成,这两个单元通过一个赖氨酸残基相连。水苏糖素B和C是水苏糖素A的衍生物,在不同十氢化萘单元的相同位置上有一个额外的羟基。
