luciferin and its analogues were synthesized from 2-aminopyrazine by an eight-step method that included two regio-selective Pd-mediated cross couplings, and their chemi- and bioluminescent activities were compared. Analogues having a 3-benzofuranyl or a 3-benzothienyl group in the place of a 3-indolyl group showed luciferase affinities similar to Cypridina luciferase but with a lower luminescent efficiency
通过八步法从2-氨基吡嗪合成了dl- Cypridina luciferin及其类似物,该方法包括两个区域选择性Pd介导的交叉偶联,并比较了它们的化学发光和生物发光活性。具有3-苯并呋喃基或3-苯并噻吩基取代3-吲哚基的类似物显示出类似于Cypridina luciferase的萤光素酶亲和力,但发光效率较低,这表明NH基对于分子识别并不重要,而吲哚基是对于有效发光至关重要。
