DESCRIPTION (provided by applicant): The identification of agents that can either treat or halt the spread of smallpox or other diseases caused by orthopox viruses would have great benefit in mitigating the risk of the orthopox virus being used as a biological weapon. Furthermore such agents would be useful as a therapeutic for accidental exposure to other orthopox viruses such as the recently publicized cases of monkey pox caused by human exposure to exotic imported animals. The ideal therapeutic would be an effective and safe orally available small molecule that could be taken by individuals who were exposed to an orthopox virus or had active disease. Recent evidence suggests that the proteolytic activity of a novel protease encoded by the orthopox virus genome is an obligatory event for viral proliferation. Using a proprietary process of drug discovery called TTP Translational Technology TM that combines novel medicinal chemistry with computer modeling and a series of in vitro biological screening assays, TransTech Pharma proposes to discover small molecule inhibitors of the orthopox protease that have drug like characteristics in terms of potency, safety and pharmacokinetic characteristics as a first step in developing a therapeutic anti-viral for the treatment of infections caused by the orthopox virus.

描述（由申请人提供）：确定可以治疗或阻止天花或由正痘病毒引起的其他疾病传播的药剂，将极大地有助于减轻正痘病毒被用作生物武器的风险。此外，对于意外暴露于其他正痘病毒，例如最近公布的因人类接触外来进口动物而引起的猴痘病例，这类药剂可用于治疗。理想的治疗方法是一种有效且安全的口服小分子药物，可以让接触过正畸病毒或患有活动性疾病的人服用。最近的证据表明，正痘病毒基因组编码的一种新型蛋白酶的蛋白水解活性是病毒增殖的必要事件。TransTech Pharma采用名为TTP Translational Technology TM的专利药物发现过程，将新型药物化学与计算机建模和一系列体外生物筛选分析相结合，提出发现在效力方面具有类似药物特征的正骨蛋白酶的小分子抑制剂。安全性和药代动力学特性作为开发治疗性抗病毒治疗由正痘病毒引起的感染的第一步。
