Abstract

Keratoconus (KC) is a serious disease that can affect people of any race or nationality, although the exact etiology and pathogenic mechanism are still unknown. In this study, thirty-two FDA-approved ophthalmic drugs were exposed to virtual screening using docking studies against both the MMP-2 and MMP-9 proteins to find the most promising inhibitors as a proposed computational mechanism to treat keratoconus. Matrix metalloproteinases (MMPs) are zinc-dependent proteases, and MMP inhibitors (MMPIs) are usually designed to interact with zinc ion in the catalytic (CAT) domain, thus interfering with enzymatic activity. In our research work, the FDA-approved ophthalmic medications will be investigated as MMPIs, to explore if they can be repurposed for KC treatment. The obtained findings of the docking study suggest that atenolol and ampicillin are able to accommodate into the active sites of MMP-2 and MMP-9. Additionally, both exhibited binding modes similar to inhibitors used as references, with an ability to bind to the zinc of the CAT. Molecular dynamic simulations and the MM-GBSA binding free-energy calculations revealed their stable binding over the course of 50 ns. An additional pharmacophoric study was carried out on MMP-9 (PDB ID: 1GKC) using the co-crystallized ligand as a reference for the future design and screening of the MMP-9 inhibitors. These promising results open the door to further biological research to confirm such theoretical results.

摘要

圆锥角膜(KC)是一种严重的疾病,可影响任何种族或民族的人,尽管确切的病因和发病机制仍不清楚。在这项研究中,使用对接研究对 32 种已获得 FDA 批准的眼科药物针对 MMP-2 和 MMP-9 蛋白进行虚拟筛选,以寻找最有前途的抑制剂,作为治疗圆锥角膜的计算机制。基质金属蛋白酶(MMPs)是锌依赖性蛋白酶,MMP 抑制剂(MMPI)通常设计为与催化(CAT)域中的锌离子相互作用,从而干扰酶活性。在我们的研究工作中,将研究已获得 FDA 批准的眼科药物作为 MMPIs,以探索它们是否可用于治疗 KC。对接研究的结果表明,阿替洛尔和氨苄西林能够适应 MMP-2 和 MMP-9 的活性部位。此外,两者都表现出与用作参考的抑制剂相似的结合模式,能够与 CAT 的锌结合。分子动力学模拟和 MM-GBSA 结合自由能计算表明,它们在 50 ns 的过程中保持稳定结合。对 MMP-9(PDB ID:1GKC)进行了额外的药效团研究,使用共晶配体作为未来 MMP-9 抑制剂的设计和筛选的参考。这些有希望的结果为进一步的生物学研究打开了大门,以证实这些理论结果。
