A derivative series of 3,4-dimethoxy-β-nitrostyrene was synthesized through nitroaldol reaction, including a new compound of 3,4-ethylenedioxy-β-bromo-β-nitrostyrene. The antimicrobial activity effect of 3,4-alkyloxy modification of β-nitrostyrene was investigated. A molecular docking study was also performed to obtain information about their interactions with protein tyrosine phosphatase 1B (PTP1B). The active residues of cysteine-215 and arginine-221 of PTP1B play a key role in signaling pathways that regulate various microorganism cell functions. It also acts as a negative regulator in signaling pathways of insulin that are involved in type 2 diabetes and other metabolic diseases. These derivatives exhibited potential antifungal activity. The studied compounds were also had potential as fragments to be PTP1B inhibitors by interacting with serine-216 and arginine-221 residues, according to their molecular docking. 3,4-Ethylenedioxy-β-methyl-β-nitrostyrene was the most successful potential candidate as a PTP1B inhibitor. However, further research is needed to investigate their potential for medicinal use.
一系列3,4-二甲氧基-β-硝基苯乙烯的衍生物通过硝基醛醇反应合成,包括一种新化合物3,4-乙二氧基-β-溴-β-硝基苯乙烯。研究了β-硝基苯乙烯的3,4-烷氧基修饰对抗菌活性的影响。还进行了分子对接研究,以获取它们与蛋白酪氨酸磷酸酶1B(PTP1B)的相互作用信息。PTP1B的半胱氨酸-215和精氨酸-221的活性残基在调节各种微生物细胞功能的信号通路中起关键作用。它还在参与第2型糖尿病和其他代谢性疾病的胰岛素信号通路中充当负调节因子。这些衍生物表现出潜在的抗真菌活性。根据它们的分子对接,研究化合物也具有潜力作为与丝氨酸-216和精氨酸-221残基相互作用的PTP1B抑制剂片段。3,4-乙二氧基-β-甲基-β-硝基苯乙烯是最成功的潜在PTP1B抑制剂候选化合物。然而,需要进一步研究它们在药用方面的潜力。
