A series of some new trans 2,3-dihydrofuran-linked pyrazole hybrids were synthesized from a convenient one-pot methodology. This procedure employs a sequential one-pot, two-step tandem reaction starting from pyridine, formylpyrazole, dimedone, and phenacyl bromide, with triethylamine serving as the base and proceeds efficiently in acetonitrile. The recently synthesized compounds were characterized through H and C NMR, Mass and IR spectroscopy and evaluated for their anti-inflammatory and anti-malarial potentials. Among the evaluated compounds, the derivative 4l, featuring a bromo group on the acetylphenyl and a methoxy group on the formylpyrazole phenyl ring, demonstrated potent anti-inflammatory activity with an IC value of 7.12 ± 0.03 μM. This potency was comparable to that of the standard drug diclofenac sodium (IC = 6.44 ± 0.02 μM). Additionally, 4l exhibited moderate anti-malarial properties with an IC value of 1.66 ± 0.04 μM, with respect to the reference drug quinine (IC = 0.26 ± 0.03 μM). Molecular docking studies were also performed to observe molecular interaction between the synthesized molecules and Enoyl-acyl-carrier-protein reductase (PDB ID: 1NHG) and Cyclooxygenase-2 inhibitors (3LN1). These studies provided valuable insights into the binding modes and affinities of the synthesized compounds, which may inform the design of future therapeutic agents.
通过简便的一锅法合成了一系列新型反式2,3-二氢呋喃连接的吡唑杂化物。该方法采用一锅两步串联反应,从吡啶、甲酰基吡唑、二氢嘧啶酮和苯甲酰溴开始,以三乙胺为碱,在乙腈中高效进行。通过氢核磁共振、碳核磁共振、质谱和红外光谱对新合成的化合物进行了表征,并评估了它们的抗炎和抗疟疾潜力。在评估的化合物中,衍生物4l在乙酰苯基上有一个溴基团,在甲酰基吡唑苯环上有一个甲氧基,表现出强大的抗炎活性,IC值为7.12±0.03μM。这种效力与标准药物双氯芬酸钠(IC = 6.44±0.02μM)相当。此外,相对于参考药物奎宁(IC = 0.26±0.03μM),4l表现出中等的抗疟疾特性,IC值为1.66±0.04μM。还进行了分子对接研究,以观察合成分子与烯酰-酰基载体蛋白还原酶(PDB ID:1NHG)和环氧合酶-2抑制剂(3LN1)之间的分子相互作用。这些研究为合成化合物的结合模式和亲和力提供了有价值的见解,这可能为未来治疗药物的设计提供参考。
