Overexpression of human epidermal growth factor receptor 2 (HER2) plays an important role in the development and progression in a variety of cancers and it is a novel therapeutic target for breast cancer and ovarian cancer. () is a South African medicinal plant in the family Ebenaceae used in the management of different human diseases and disorders.
The aim of this study was to evaluate the potential inhibitors against HER2 from hexane extract of leaves.
Chemical fingerprinting method was used to identify the presence of natural compounds from the extract whereas their inhibitory activities were analyzed by molecular docking analysis against HER2. Absorption, distribution, metabolism, and excretion (ADME) properties also predicted to establish the pharmacokinetics and pharmacodynamics profiles of the selected compounds.
The molecular docking analysis expressed that phenyl glucuronide, hydrocortisone acetate, and 6-(4,6-dioxo-1,4,5,6-tetrahydropyrimidin-2-yl-amino)hexanoic acid trifluoroacetate possess good inhibitory activities with good glide score of -6.63, -5.41, and -5.40 and glide energy of -35.03, -42.51, and -31.38 kcal/mol, respectively when compared with standard Food and Drug Administration-approved drug and other compounds. All the screened compounds were within the acceptable and permissible limits of ADME properties.
Thus, from this study it can be concluded that, these screened natural compounds from leaves may serve as potential inhibitors for HER2 and they might lead to development of new therapeutic agents against cancer and its associated complications.
人表皮生长因子受体2(HER2)的过表达在多种癌症的发生和发展中起重要作用,是乳腺癌和卵巢癌的新型治疗靶点。()是柿科的一种南非药用植物,用于治疗不同的人类疾病和病症。
本研究旨在评估从叶的己烷提取物中筛选出的HER2潜在抑制剂。
采用化学指纹图谱法鉴定提取物中天然化合物的存在,通过分子对接分析其对HER2的抑制活性。还预测了吸收、分布、代谢和排泄(ADME)特性,以建立所选化合物的药代动力学和药效学特征。
分子对接分析表明,与美国食品药品监督管理局批准的标准药物和其他化合物相比,苯基葡萄糖醛酸、醋酸氢化可的松和6-(4,6-二氧代-1,4,5,6-四氢嘧啶-2-基氨基)己酸三氟乙酸盐具有良好的抑制活性,其滑行评分分别为-6.63、-5.41和-5.40,滑行能量分别为-35.03、-42.51和-31.38 kcal/mol。所有筛选出的化合物均在ADME特性的可接受和允许范围内。
因此,从本研究可以得出结论,这些从叶中筛选出的天然化合物可能作为HER2的潜在抑制剂,可能会导致开发针对癌症及其相关并发症的新型治疗药物。
