Abstract

Kipas laut (Gorgonia mariae) telah digunakan masyarakat Maluku secara turun temurun sebagai obat asma. Kandungan metabolit sekunder yang paling dominan dalam kipas laut adalah sterol, dimana memiliki aktivitas terapi melalui efek sinergisme antara senyawa metabolit dengan polivalent activity. Pengujian kipas laut sebagai anti-asma belum pernah dilaporkan sebelumnya. Oleh karena itu, perlu dilakukan virtual screening menggunakan metode in silico pada komponen sterol kipas laut sebagai tahap awal dalam menentukan efektivitas terapi anti-asma dengan memprediksi nilai ikatan energi bebas (ΔG), konstanta inhibisi (Ki), dan interaksi residu asam amino menggunakan Autodock Tools 4.2 dan Discovery Studio 2016 Client®. Keamanan dan efektivitas kandidat obat dievaluasi menggunakan parameter dari Lipinski Rule of Five dan pre-ADMET. Hasil penelitian menunjukkan bahwa konstanta inhibisi dan ikatan energi bebas (Ki; ΔG) dari komponen senyawa kipas laut dapat diurutkan secara potensial yaitu 4,24-dimetil kolestanol  (0,809; -12,40) > 24-metil-22-dehidrokolesterol (0,864; -12,36) > 23-demetil gorgosterol (1,74; -11,95) > 4,24-dimetil-22-dehidrokolestanol (1,89; -11,90). Residu asam amino yang berperan penting dalam aktivitas inhibisi hCHIT1 adalah 213-ASP. Semua komponen senyawa uji memiliki nilai log P lebih dari 5 yang menunjukkan bahwa kelarutan dan toksisitas perlu diperhatikan. Evaluasi distribusi pre-ADMET berdasarkan nilai dari pengikatan protein plasma menunjukan bahwa senyawa uji dapat berdifusi menembus membran plasma dan berinteraksi sesuai target farmakologi. Selain itu, hasil parameter uji toksisitas menunjukkan bahwa senyawa 23-demetil gorgosterol dan 4,24-dimetil-22-dehidrokolestanol memiliki potensi sebagai anti-asma.Virtual Screening of the Compounds in Gorgonians (Gorgonia mariae) as anti-asthma. The people of Maluku have used Kipas laut (G. mariae) for generations as an asthma medicine. The secondary metabolite that is most dominant in kipas laut is sterols, which have therapeutic activity through the synergistic effect between metabolite compounds and polyvalent activity. Anti-asthma activity of kipas laut has never been reported. Therefore, it is necessary to do virtual screening using the in silico method on the sterol component of kipas laut as a first step in determining the effectiveness of anti-asthma therapy by predicting the value of free energy bonds (ΔG), constant inhibition (Ki), and interactions of amino acid residues using Autodock Tools 4.2 and Discovery Studio 2016 Client®. The effectiveness and safety of prospective drugs are evaluated using the Lipinski Rule of Five and pre-ADMET. The results showed that the value of inhibition constants and free energy bonds (Ki; ΔG) on the compound of kipas laut that was potentially sorted was 4.24-dimethyl cholestanol (0.809; -12.40) > 24-methyl-22-dehydrocholesterol (0.864; -12.36) > 23-demethyl gorgosterol (1.74; -11.95) > 4.24-dimethyl-22-dehidrokolestanol (1.89; -11.90). The crucial residues of amino acids is 213-ASP, which play a significant role in hCHIT1 inhibitory activity.

Evaluation of the pre-ADMET based on the value of plasma protein binding shows that the test compound can diffuse through the plasma membrane and interact according to pharmacological targets. In addition, the results of the toxicity test showed that 23-demethyl gorgosterol and 4.24-dimethyl-22-dehidrokolestanol compounds have potential as anti-asthma.
海扇(mariae)长期以来一直将马卢库人用作治疗哮喘的药物。扇形中最占主导作用的次级代谢醇是sterol,它通过代谢化合物和多碱性活动之间的协同作用进行治疗。海风扇的抗哮喘测试前所未有。因此,需要虚拟筛选使用in silico方法对组件做sterol海扇作为早期阶段决定自由价值的预测为anti-asma能量结合疗法的有效性(ΔG)的抑制常数(Ki),氨基酸残留物用Autodock互动工具探索工作室2016年客户®4。2和。使用利马和前期药物的参数对候选人的安全性和有效性进行了评估。研究结果表明,抑制常数和自由能键(Ki;ΔG)的海扇化合物成分可以潜在地排序4,24-dimetil kolestanol (0.809;- 12.40) > 24甲基-22-无胆固醇(0.864;-12 36) > 23狄米提尔gorgosterol (1.74;- 11.95) > 4.24 - dimetiii -22- de羟基醇(1.89;-11,90)。氨基酸的残留物在hCHIT1的抑制活动中扮演着重要的角色是213-ASP。所有测试化合物的成分都有超过5个P值,这表明溶液和毒性需要注意。基于血浆蛋白粘合的价值的前admet分配评价表明,测试化合物可以通过血浆细胞膜进行渗透,并在药理学目标上相互作用。此外,毒性检测参数的结果表明,23狄米提尔高浓度醇和4.24 -二二醇有抗哮喘的潜力。美国反哮喘组织的虚拟放映。马鲁库的人民已经使用了一代风信子。海洋风扇中最受控制的代谢是麻醉剂,这种代谢作用通过代谢结合和多代谢活动的作用进行治疗。海风活动从未报道过。这就是用的,是有必要做虚拟筛选in silico方法在《海扇sterol组件显示其》美国第一step in determining anti-asthma疗法:predicting the value of free energy债券ΔG),康斯坦抑制(Ki),用Autodock》和氨基酸酸residues interactions工具探索工作室2016年客户®4。2和。使用利马和前admet的利平斯基和安全措施来评估未来毒品的有效性和安全。推荐人指出,持续的抑制和无能量结合的价值(Ki;ΔG)在海扇之化合物这就是潜在地sorted 4 . 24-dimethyl cholestanol (0.809;12.40) > 24-甲基-22-脱氧核糖醇(0864;12.36) > 23-demethyl gorgosterol (1.74;11.95) > 4.24-二十二-脱氢胆固醇(1.89;- 11 . 90)。氨基酸的壳剩余是213-ASP,在hCHIT1事件中扮演有意义的角色。所有的化合物测试都有价值超过5种的日志,这是需要考虑的潜在解决方案和毒药。基于合成血浆的相位蛋白指数的价值,化合物可以通过膜膜等离子体和对位对制药目标进行计算。此外,毒物测试的结果表明,23狄米提基高血糖醇和4。24-二甲甲基化合物化合物具有抗哮喘的效力。
