isatin-hydrazide conjugates 1a – 1j that are easily accessed in two steps from simple and inexpensive commercially available isatin. The in vitro bio-evaluations of these compounds revealed that conjugates 1a, 1h and 1f are highly potent inhibitors of α-amylase with IC50 values of 19.6, 12.1 and 18.3 µg/ml, respectively as compared to the standard, acarbose (IC50 = 36.2 µg/ml). Similarly, the conjugates 1a, 1b
管理糖尿病是一个全球性的威胁生命的问题,仍然是科学界面临的挑战。抑制负责消化膳食碳水化合物的α-淀粉酶和α-葡萄糖苷酶是控制餐后高血糖的有效策略。在此,我们报告了 α-淀粉酶和 α-葡萄糖苷酶的新型高效抑制剂,即靛红-酰肼偶联物1a-1j,可通过简单且廉价的市售靛红分两步轻松获得。在体外,这些化合物的生物评价表明,共轭物1a中,1 ħ和1F是与ICα淀粉酶的强效抑制剂50与标准品阿卡波糖相比,其值分别为 19.6、12.1 和 18.3 µg/ml(IC 50 = 36.2 µg/ml)。类似地,共轭物1A,1B,1D,1F和1I显示对α葡糖苷显著活性,IC 50倍的14.8的值,25.6,13.2,14.5和16.5微克/毫升,分别相比于阿卡波糖(IC 50 = 34.5微克/毫升)。值得注意的是,化合物1a和1f发现对 α-淀粉酶和 α-葡萄糖苷酶均具有高度效力,显示出比参考抑制剂
