UNLABELLED
In structure-based drug design, automated de novo design methods are helpful tools for lead discovery as well as lead optimization. In a previous study ( J. Chem. Inf.
MODEL
2011 , 51 , 1474 - 1491 ) we reported a new de novo design method, namely, Automatic Tailoring and Transplanting (AutoT&T). It overcomes some intrinsic problems in conventional fragment-based buildup methods. In this study, we describe an upgraded version, namely, AutoT&T2. Structural operations conducted by AutoT&T2 have been largely optimized by introducing several new algorithms. As a result, its overall speed in multiround optimization jobs has been improved by a few thousand fold. With this improvement, it is now practical to conduct structural crossover among multiple lead molecules using AutoT&T2. Three different test cases are described in this study that demonstrate the new features and versatile applications of AutoT&T2. The AutoT&T2 software suite is available to the public. Besides, a Web portal for running AutoT&T2 online is provided at http://www.sioc-ccbg.ac.cn/software/att2 for testing.

在基于结构的药物设计中，自动从头设计方法是先导化合物发现和优化的有用工具。在之前的一项研究（《化学信息与建模杂志》：2011年，51卷，1474 - 1491页）中，我们报道了一种新的从头设计方法，即自动剪裁与移植（AutoT&T）。它克服了传统基于片段构建方法中的一些固有问题。在本研究中，我们描述了一个升级版，即AutoT&T2。通过引入几种新算法，AutoT&T2进行的结构操作已得到很大优化。结果，其在多轮优化任务中的整体速度提高了数千倍。有了这一改进，现在使用AutoT&T2在多个先导分子之间进行结构交叉变得可行。本研究描述了三个不同的测试案例，展示了AutoT&T2的新特性和广泛应用。AutoT&T2软件套件可供公众使用。此外，还提供了一个在线运行AutoT&T2的网站门户：http://www.sioc-ccbg.ac.cn/software/att2 用于测试。
