acids bearing amide moiety were designed and synthesized by Doebner reaction. Human dihydroorotate dehydrogenase (hDHODH) was recognized as a biological target and all compounds were screened as potential hDHODH inhibitors in an enzyme inhibition assay. The prepared heterocycles were also evaluated for their cytotoxic effects on the healthy HaCaT cell line while lipophilic properties were considered
derivatives (7a–m) were designed based on a molecular hybridization approach as new α-glucosidase inhibitors. These compounds were synthesized with high yields and evaluated in vitro for their inhibitory activity against yeast α-glucosidase. The obtained results revealed that a significant proportion of the synthesized compounds showed considerable α-glucosidase-inhibitory activity in comparison to acarbose

Among them, 2-mehoxy-phenoxy derivatives 7l and 7h with 4-nitro and 4-chloro substituents on the phenyl ring of the N-phenylacetamide moiety, respectively, displayed the most inhibition effects. The inhibitory mechanism of these compounds was investigated by molecular docking studies. The in vitro cytotoxicity assay showed that only one compound, 2-methoxy-phenoxy derivative 7k with a 4-bromo substituent
设计、合成了一系列新的吲哚-碳酰肼-苯氧基-N-苯基乙酰胺衍生物7a-l,并筛选了它们的 α-葡萄糖苷酶抑制能力和细胞毒性作用。在 α-葡萄糖苷酶抑制试验中获得的结果表明,与标准药物阿卡波糖 ( K i = 42.38 ) 相比,大多数合成衍生物显示出良好至中度的抑制能力( K i值范围为 14.65 ± 2.54 至 37.466 ± 6.46 μM) ± 5.73 微米)。其中, N的苯环上有4-硝基和4-氯取代基的2-甲氧基-苯氧基衍生物7l和7h-苯基乙酰胺部分分别显示出最大的抑制作用。通过分子对接研究研究了这些化合物的抑制机制。体外细胞毒性测定表明,只有一种化合物,即在N-苯基乙酰胺部分的苯环上具有 4-溴取代基的2-甲氧基-苯氧基衍生物7k,对人非小细胞肺癌细胞系表现出中等的细胞毒性A549 和其余化合物几乎没有细胞毒性。还对化合物7k进行了进一步的细胞毒性评估。计算机模拟药

The present invention is directed to a method for the synthesis of a bi-functional complex comprising a molecule part and an identifier oligonucleotide part identifying the molecule part. A part of the synthesis method according to the present invention is preferably conducted in one or more organic solvents when a nascent bi-functional complex comprising an optionally protected tag or oligonucleotide identifier is linked to a solid support, and another part of the synthesis method is preferably conducted under conditions suitable for enzymatic addition of an oligonucleotide tag to a nascent bi-functional complex in solution.
