Abstract

Inflamasi merupakan suatu respon dari tubuh terhadap adanya cedera maupun infeksi yang ditandai dengan timbulnya kemerahan, demam, bengkak, nyeri dan hilangnya fungsi. Inflamasi berkontribusi terhadap ketidakseimbangan sekresi sitokin yang akan menghambat terjadinya apoptosis pada sel kanker sehingga menyebabkan hiperproliferasi sel. Kanker payudara merupakan salah satu penyakit kanker dengan prevalensi tertinggi di urutan ke dua di dunia. Penelitian terdahulu melaporkan pemberian minyak atsiri rimpang bangle (Zingiber purpureum Roxb.) secara topikal mampu memberikan penghambatan inflamasi yang lebih tinggi daripada triamcinolone, namun spesifik senyawa yang berpotensinya belum diketahui. Tujuan dari penelitian ini, yakni mencari senyawa aktif hasil analisis GCMS minyak atsiri rimpang bangle yang berpotensi sebagai antiinflamasi dan antikanker payudara secara in silico.

研究二氧化硅化合物1,4- naphthalenedion2 -3-羟基以抗炎症和乳腺癌为食
炎症是身体对发红、发热、肿胀、疼痛和功能丧失的反应。炎症会导致细胞分泌不平衡,而细胞分泌会抑制癌细胞的凋亡,导致细胞增殖。乳腺癌是世界第二常见的癌症之一。过去的研究报告称,atsiri rimpang bangle (Zingiber purpureum Roxb)的油在局部作用下提供了比triamcinolone更高的炎症抑制,但其潜在化合物的具体性质尚不清楚。这项研究的目的是寻找二甲二甲油中可能用作消炎药和二氧化硫抗癌的活性化合物。采用筛选利平斯基的五定律、药理学和药物毒性分析GC-MS,以及分子增强和分子动力学等方法。筛选和确保模拟结果表明1,4-naphthalenedione-2-ethyl-3-hydroxy化合物分子可以结合COX-1受体(antiinflamasi),和她的α受体(抗癌)的胸部,但更有选择性的能量和价值COX-1大小较小的自由(ΔG)即-7,20 kkal / mol相比,呃α受体的互动价值-6,00 kkal / mol。用分子动力学模拟方法计算结果MM-GBSA表明复杂(1,4-naphthalenedione-2-ethyl-3-hydroxy) - (COX-1)成绩∆GTOTAL高达-24,22 kkal / mol。∆相比,这个值较小GTOTAL复杂(1,4-naphthalenedione-2-ethyl-3-hydroxy) -(她α)大-8,92 kkal / mol)。这表明,亲和度为1 - 4- naphthalenedie -2在硅研究中,4- naphthalenedion2 -3-羟基化合物抗炎症和反消炎药。红外线是对身体的一种反应,其作用在于红润、发热、膨胀、疼痛和功能丧失。血管增殖与癌症细胞凋亡,细胞增殖。巨蟹座是世界上第二高的优先级之一。《先驱报》报道了Bangle的目标应用可以提供比triamcinolone、however、该化合物的具体潜力更高的红外线抑制。这项研究的目的是寻找一种可能存在于磷酸中、二氧化硅接近中的抗炎和抗癌症的活性化合物。使用的方法正在筛选利平斯基的五种规则,来自GC-MS分析和分子动力学和分子动力学的药理学和毒药。对接的筛选和分子模拟results那里那个化合物1,4-naphthalenedione-2-ethyl-3-hydroxy可以捆绑到COX-1杂志》(抗炎药),和二α(雌激素受体α),但更多的是selective向COX-1受体with a印象深刻affinity(ΔG) - 7。20 kcal / mol,不如到它的interaction with呃α哪种是sd -点kcal / mol。用的分子动力学模拟之results MM-GBSA calculation方法表演那情结(1,4-naphthalenedione-2-ethyl-3-hydroxy) -(∆的COX-1)有a价值之GTOTAL kcal / mol) 22 - 24。这个价值是小比∆GTOTAL》情结(1,4-naphthalenedione-2-ethyl-3-hydroxy) -(她的α)公关92 kcal / mol。这种不稳定的反应是4- 4- naphthalenedie -2
