Arg-Gly-Asp (RGD) mimics were synthesized and their anti-platelet activity was evaluated. A concise method was developed for the synthesis of the target compounds from dehydroepiandrosterone and Wieland–Miescher and Hajos–Parrish ketones, which are suitable for readily available platform. Among the synthesized compounds, the perhydronaphthalene framework with a 3-(4-piperidinyl)propoxyl structure 3e possessed the highest anti-aggregative activity. The IC50 values of 3e were 0.91 mM (ADP initiation) and 0.54 mM (collagen initiation).
合成了Arg-Gly-Asp(RGD)模拟物并评估了它们的抗血小板活性。开发了一种简便的方法,从脱氢表雄酮、Wieland-Miescher酮和Hajos-Parrish酮合成目标化合物,这些酮适用于易于获得的平台。在合成的化合物中,具有3-(4-哌啶基)丙氧基结构的全氢萘框架3e表现出最高的抗聚集活性。3e的IC50值分别为0.91 mM(ADP诱导)和0.54 mM(胶原蛋白诱导)。
