A new class of potent, orally active phenyl piperazine-based GH secretagogues have been discovered from attempts to mimic the arrangement of the phenyl substituent in the spiroindanyl piperidine and spiroindoline sulfonamide privileged structures of 4 and 1, respectively. The best of these compounds, 18 (EC50 = 2.8 nM) is nearly as potent as MK-0677 for releasing GH from rat pituitary cells.
通过尝试模仿分别为4和1的螺二氢茚基哌啶和螺二氢吲哚磺酰胺特权结构中的苯基取代基排列,发现了一种新型的,基于口服活性的苯基哌嗪基的GH促分泌剂。这些化合物中最好的18种(EC50 = 2.8 nM)几乎可以与MK-0677一样有效地从大鼠垂体细胞释放GH。
