Diazipine and [3H]diazipine were synthesized as new 1, 4-dihydropyridine photoaffinity ligands containing a phenyldiazirine group. After simple high performance liquid chromatography separation, both compounds were purified in good overall yields. [3H]Diazipine (21.2Ci/mmol) was synthesized in two steps from commercially available [3H]ethanolamine. Diazipine competitively inhibited [3H]PN200-110 binding to the calcium channel of cardiac membranes with high affinity.
Diazipine 和 [3H]diazipine 被合成作为新的 1, 4-二氢吡啶光亲和配体,含有苯基二氮烯基团。在简单的高效液相色谱分离后,这两种化合物均以良好的总体产率得到纯化。[3H]Diazipine(21.2Ci/mmol)通过两步合成自市售的 [3H]乙醇胺。Diazipine 以高亲和力竞争性抑制 [3H]PN200-110 与心脏膜上钙通道的结合。
