  Identification and structure–activity relationship (SAR) studies of carvacrol derivatives as potential anti-malarial against Plasmodium falciparum falcipain-2 protease

  摘要：

  In an effort to develop a potent anti-malarial agent against Plasmodium falciparum, a structure-guided virtual screening using an in-house library comprising 652 compounds was performed. By docking studies, we identified two compounds (JMI-105 and JMI-346) which formed significant non-covalent interactions and fit well in the binding pocket of PfFP-2. We affirmed this observation by MD simulation studies. As evident by the biochemical analysis, such as enzyme inhibition assay, Surface Plasmon Resonance (SPR), live-cell imaging and hemozoin inhibition, JMI-105 and JMI-346 at 25 mu M concentration showed an inhibitory effect on purified PfFP-2. JMI-105 and JMI-346 inhibited the growth of CQ(s) (3D7; IC50 = 8.8 and 13 mu M) and CQ(R) (RKL-9; IC50 = 14.3 and 33 mu M) strains of P. falciparum. Treatment with compounds resulted in defect in parasite growth and development. No significant hemolysis or cytotoxicity towards human cells was observed suggesting that these molecules are non-toxic. We pursued, structural optimization on JMI-105 and in the process, SAR oriented derivatives (5a-5l) were synthesized and evaluated for growth inhibition potential. JMI-105 significantly decreased parasitemia and prolonged host survival in a murine model with P. berghei ANKA infection. The compounds (JMI-105 and JMI-346) against PfFP-2 have the potential to be used as an anti-malarial agent.

  香芹酚衍生物作为幽门螺杆菌菌株和 AGS 细胞增殖双重抑制剂的合成和生物学评价

  摘要：

  本研究报告了一系列基于香芹酚的化合物的合成、结构评估、针对多种幽门螺杆菌菌株的微生物筛选以及针对人胃腺癌细胞（AGS）细胞的抗增殖活性。结构分析包括元素分析、1H/13C/19F NMR 谱和晶体学研究。构效关系表明，在醚类衍生物中，特定吸电子基团（CF3和NO2）的取代，特别是在苄基环的对位上，可以提高抗菌活性，而苄基环上的给电子基团则可以提高抗菌活性。相对于母体化合物，醚烷基链不耐受 (MIC/MBC = 64/64 µg/mL)。酯衍生物（香豆素-香芹酚杂化物）的抑制活性略有增强，MIC 值高达 8–16 µg/mL。还分析了对幽门螺杆菌表现出最低 MIC/MBC 活性的最有趣的化合物（其中，化合物 16 和 39 对所有评估菌株的 MIC/MBC 值范围在 2/2 至 32/32 µg/mL 之间）与 5-氟尿嘧啶相比，它们能够减少 AGS 细胞的生长。一些衍生物可以被视为新的先导

  As part of our effort to develop potential tyrosinase inhibitors, we have conjugated the well-known tyrosinase inhibitor kojic acid (KA) with several phenolic natural products such as umbelliferone, sesamol, thymol, carvacrol, eugenol, isoeugenol, vanillin, isovanillin, and apocynin that some reports have shown their activity on tyrosinase enzyme. The designed compounds were synthesized using click reaction and 1,2,3-triazole formation. All compound showed potent anti-tyrosinase activity significantly higher than KA. The best activities were observed with apocynin and 4-coumarinol analogs (10c and 16c) displaying IC50 values of 0.03 and 0.02 mu M, respectively. The potency of 16c was >460-times more than that of KA. Cell-based assays against B16F10 and HFF cells revealed that the representative compounds can efficiently suppress the melanogenesis without significant toxicity on cells.

  This study performed a comparative investigation to explore the interaction mechanisms between two potential antimalarial compounds, JMI 346 and JMI 105, and human serum albumin (HSA), a vital carrier protein responsible for maintaining important biological functions. Our aim was to assess the pharmacological efficiency of these compounds while comprehensively analyzing their impact on the dynamic behavior and overall stability of the protein. A comprehensive array of multispectroscopic techniques, including UV–Vis. spectroscopy, steady‐state fluorescence analysis, synchronous fluorescence spectroscopy, three‐dimensional fluorescence and circular dichroism spectroscopy, docking studies, and molecular dynamics simulations, were performed to probe the intricate details of the interaction between the compounds and HSA. Our results revealed that both JMI 346 and JMI 105 exhibited promising pharmacological effectiveness within the context of malaria therapy. However, JMI 346 was found to exhibit a significantly higher affinity and only minor altered impact on HSA, suggesting a more favorable interaction with the protein on the dynamic behavior and overall stability of the protein in comparison to JMI 105. Further studies can build on these results to optimize the drug–protein interaction and enable the development of more potent and targeted antimalarial treatments.
