摘要

甲型H1N1流感病毒对许多国家的公共卫生造成危害。因此,由于病毒的高突变率,现有的流感药物无法应对H1N1感染。在这方面,设计了新的阻断病毒的方法。聚合酶PAC-PB1N酶负责H1N1病毒的复制。因此,开发了新的抑制剂来抵御酶的功能。本研究选择环肽来抑制PAC-PB1N,因为环肽在达到药物靶点方面具有稳定性。因此,利用MOE 2008.10软件中的LigX工具,开发了阐明环肽与PAC-PB1N分子相互作用的计算方法。这些工具可以呈现交互中涉及的绑定。抑制剂中单个氨基酸与酶之间的相互作用也可以看到。因此,选择CKTTC和CKKTC的肽序列作为先导化合物。因此,环状肽作为H1N1候选药物的可行性可以通过分子相互作用的二维和三维建模来揭示。

The Complexity of Molecular Interactions and Bindings between Cyclic Peptide and Inhibit Polymerase A and B1 (PAC-PB1N) H1N1
The influenza/H1N1 virus has caused hazard in the public health of many countries. Hence, existing influenza drugs could not cope with H1N1 infection due to the high mutation rate of the virus. In this respect, new method to block the virus was devised. The polymerase PAC-PB1N enzyme is responsible for the replication of H1N1 virus. Thus, novel inhibitors were developed to ward off the functionality of the enzyme. In this research, cyclic peptides has been chosen to inhibit PAC-PB1N due to its proven stability in reaching the drug target. Thus, computational method for elucidating the molecular interaction between cyclic peptides and PAC-PB1N has been developed by using the LigX tools from MOE 2008.10 software. The tools could render the bindings that involved in the interactions. The interactions between individual amino acid in the inhibitor and enzyme could be seen as well. Thus, the peptide sequences of CKTTC and CKKTC were chosen as the lead compounds. In this end, the feasibility of cyclic peptides to act as drug candidate for H1N1 could be exposed by the 2d and 3d modeling of the molecular interactions.
