  Synthesis and in Vitro Evaluation of Two Progressive Series of Bifunctional Polyhydroxybenzamide Catechol-O-methyltransferase Inhibitors

  摘要：

  Two progressive series of molecules with two polyhydroxybenzamide substructures were synthesized and tested as potential inhibitors of catechol-O-methyltransferase (COMT). These compounds were designed for the purpose of enhanced enzyme binding with duplicated substructures separated by a linker section of various lengths. Our results show that potency and mode of inhibition observed with the ''bifunctional'' compounds were a reflection of their bifunctional nature. Furthermore, potency and mode of inhibition were dependent on the length of the linker section. Of the assayed compounds, the optimum linker was found to be diaminopropane. For example, N,N'-1,3-propanediylbis(3,4-dihydroxybenzamide) and N,N'-1,3-propanediylbis(3,4,5-trihydroxybenzamide) demonstrated strong inhibitory action against COMT, with apparent K-i values of 0.3 and 6.0 mu M, respectively.

  The present research describes the synthesis, characterization, in vitro biological and docking evaluation of N,N'-(ethane-1,2-diyl)bis(benzamides) (3a-3j). Consequently, in in vitro hRBCs hemolysis assay, only the bis-amide (3d) induced 52.4% hemolysis at higher concentration (1000 μg/mL) that decreased drastically with concentration (250 μg/mL) to 27.9% (CC50 = 400.41). Similarly, the tested bis-amide (3j) was found to be the least toxic with 7.8% hemolysis at higher concentration (1000 μg/mL) that gradually decreases to 6.1% (CC50 = 19,347.83) at lower concentration (250 μg/mL). Accordingly, the tested bis-amides were found to be highly biocompatible against hRBCs at higher concentrations with much higher CC50 values (> 1000 μg/mL). The biocompatible bis-amides (3a-3j) were subjected to in vitro DNA ladder assay to analyze their apoptotic potential. The results obtained suggest the tested bis-amides (3a-3j) are highly degradative toward DNA causing the appearance of more than one bands or complete degradation of DNA except (3a), (3c), (3i) and (3 g). Moreover, the synthesized bis-amides (3a-3j) were tested in in vitro antileishmanial assay to unveil their leishmaniacidal potential. The results obtained clearly indicated that some of the tested bis-amides displayed good dose dependent response. The tested bis-amides were highly active at higher concentration (1000 μg/mL) against the leishmanial promastigotes and their % inhibitory potential decreased drastically with concentration (250 μg/mL). Consequently, at higher concentration (1000 μg/mL), the bis-amide (3f) caused 85% inhibition and was ranked as the most effective leishmaniacidal bis-amides followed by the bis-amide (3 g) with 73.54% inhibition of leishmanial promastigotes. However, in terms of their IC50 values, the best leishmaniacidal potential was displayed by the bis-amide (3f) followed by (3b), (3j) and (3 g) with IC50 values increasing in the order of 633.16, 680.22, 680.22 and 712.93 μg/mL, respectively. Molecular docking studies revealed that bis-amides having electron-donating groups showed good binding potential against antileishmanial target.

  本研究描述了N,N'-(乙烷-1,2-二基)双(苯酰胺)（3a-3j）的合成、表征、体外生物学评估和对接分析。因此，在体外人红细胞溶血实验中，仅有双酰胺（3d）在高浓度（1000μg/mL）下诱导了52.4%的溶血，随着浓度降低到（250μg/mL），溶血率急剧下降至27.9%（CC50=400.41）。同样，测试的双酰胺（3j）在高浓度（1000μg/mL）下被发现毒性最小，溶血率为7.8%，逐渐降低至较低浓度（250μg/mL）的6.1%（CC50=19,347.83）。因此，在高浓度下，测试的双酰胺被发现对人红细胞具有很高的生物相容性，CC50值远高于1000μg/mL。生物相容性双酰胺（3a-3j）被用于体外DNA梯形实验，以分析其诱导凋亡的潜力。获得的结果表明，测试的双酰胺（3a-3j）对DNA具有很强的降解性，导致出现多个条带或DNA的完全降解，除了（3a）、（3c）、（3i）和（3g）。此外，合成的双酰胺（3a-3j）在体外抗利什曼病实验中被测试，以揭示其杀虫潜力。获得的结果清楚地表明，部分测试的双酰胺显示出良好的剂量依赖性反应。测试的双酰胺在高浓度（1000μg/mL）下对利什曼病原虫的前鞭毛体表现出极高的活性，随着浓度降低到（250μg/mL），其%抑制潜力急剧下降。因此，在高浓度（1000μg/mL）下，双酰胺（3f）造成85%的抑制，被评为最有效的杀虫双酰胺，随后是双酰胺（3g），其对利什曼病原虫的抑制率为73.54%。然而，从其IC50值来看，最佳的杀虫潜力由双酰胺（3f）展示，其后依次为（3b）、（3j）和（3g），IC50值分别为633.16、680.22、680.22和712.93μg/mL。分子对接研究表明，具有电子供体基团的双酰胺表现出良好的结合潜力，对抗利什曼病靶点具有较强的亲和力。
