Prostate cancer is the second most fatal malignancy in men after lung cancer, and the fifth leading cause of death. Piperine has been utilized for its therapeutic effects since the time of Ayurveda. According to traditional Chinese medicine, piperine has a wide variety of pharmacological effects, including anti-inflammatory, anti-cancer, and immune-regulating properties. Based on the previous study, Akt1 (protein kinase B) is one of the targets of piperine, it belongs to the group of oncogenes and the mechanism of the Akt1 is an interesting approach for anticancer drug design. From the peer-reviewed literature, five piperine analogs were identified altogether, and a combinatorial collection was formed. However, may not be entirely clear how piperine analogs work to prevent prostate cancer. In the present study, serine-threonine kinase domain Akt1 receptor was employed to analyze the efficacy of piperine analogs against standards using in silico methodologies. Additionally, their drug-likeness was evaluated utilizing online servers like Molinspiration and preADMET. Using AutoDock Vina, the interactions of five piperine analogs and two standards with Akt1 receptor was investigated. Our study reveals that piperine analog-2 (pip2) shows highest binding affinity (6.0 kcal/mol) by forming 6 hydrogen bonds with more hydrophobic interactions compared to other four analogs and standards. In conclusion, the piperine analog pip2, which shows strong inhibition affect in Akt1-cancer pathway, may be employed as chemotherapeutic drugs.
前列腺癌是男性中仅次于肺癌的第二大致命恶性肿瘤,也是第五大死因。自阿育吠陀时代以来,胡椒碱就因其治疗作用而被使用。根据传统中医理论,胡椒碱具有多种药理作用,包括抗炎、抗癌和免疫调节特性。基于先前的研究,Akt1(蛋白激酶B)是胡椒碱的靶点之一,它属于癌基因类别,Akt1的作用机制是抗癌药物设计的一个有趣研究方向。从同行评审文献中,共鉴定出五种胡椒碱类似物,并形成了一个组合集合。然而,胡椒碱类似物如何预防前列腺癌可能并不完全清楚。在本研究中,利用计算机模拟方法,采用丝氨酸 - 苏氨酸激酶结构域Akt1受体来分析胡椒碱类似物相对于标准物的疗效。此外,利用在线服务器如Molinspiration和preADMET评估它们的类药性质。使用AutoDock Vina,研究了五种胡椒碱类似物和两种标准物与Akt1受体的相互作用。我们的研究表明,胡椒碱类似物 - 2(pip2)通过与其他四种类似物和标准物相比形成6个氢键并具有更多疏水相互作用,显示出最高的结合亲和力(6.0千卡/摩尔)。总之,在Akt1 - 癌症途径中表现出强烈抑制作用的胡椒碱类似物pip2可作为化疗药物使用。
