Cancer stem cells (CSCs) have received considerable attention from the research community since they were first reported in human acute myeloid leukemia 15 years ago. Accumulating evidence suggests that CSCs are responsible for tumor initiation and progression, drug resistance, and metastasis in both liquid and solid tumors. These findings lead to the development of novel compounds targeting CSC populations that is becoming increasingly important for eradicating CSCs in heterogeneous tumor masses and to cure the cancer. Since 2003, we have participated in CSC studies and encountered crucial early events in the field. This article reviews the history of CSC biology, clarifies the term and its definition, and further addresses the issue of how to utilize CSCs in therapeutic target discovery and drug development based on our substantial experience.

p-Hydroxyphenylpyruvate dioxygenase (EC 1.13.11.27, HPPD) belongs to the family of Fe(II)-dependent non-heme oxygenases that occur in the majority of aerobic organisms. HPPD has proved to be a promising target in herbicide research and development. A battery of novel triketone-quinoxaline compounds has been designed using a structure-based drug design strategy and then prepared. Enzyme inhibition assays show that these synthesized derivatives possess favorable inhibition capability against Arabidopsis thaliana HPPD with IC50 values ranging from 0.317 to 0.891 μmol·L−1. Subsequently, the molecular docking results indicate that two adjacent carbonyls of the triketone moiety of the representative compound 2-(2,3-dimethyl-8-(o-tolyl)quinoxaline-6-carbonyl)-3-hydroxycyclohex-2-en-1-one (7d) engage in chelation with the ferrous ion of A. thaliana HPPD in a bidentate pose, and its quinoxaline scaffold forms two sets of parallel π-stacking interaction between two phenylalanine residues (Phe424 and Phe381). In addition, the extended phenyl group also interacts with Phe392 in a π-π stacking way. This study indicates that triketone-quinoxaline is a promising scaffold for discovering HPPD inhibitors with substantially increased potency, providing insight into the molecular design of new herbicides.

药物研发影响着人类健康的方方面面,并对医药市场有着巨大的影响。然而,由于药物研发(research and development, R&D)过程漫长而复杂,对新药的投资往往收效甚微。随着实验技术和计算机硬件的发展,人工智能(artificial intelligence, AI)近些年来已成为分析大量高维数据的主要工具。生物医学数据规模的爆炸式增长更使得AI得以应用在药物研发的各个阶段。在生物医学大数据的推动下,AI能够更高效、更低成本地发现新药,从而引发了一场药物研发范式的革命。本综述首先简要介绍了药物发现领域常见的人工智能模型,然后总结并深入讨论了这些模型在药物研发各个阶段的具体应用,如靶点发现、药物发现和设计、临床前研究、药物智能制造以及对医药市场的影响。最后,充分讨论了AI在药物研发中的主要局限性,并提出了可能的解决方案。
Taking advantage of drug resistance, a new approach in the war on cancer

Identification of the driver mutations in cancer has resulted in the development of a new category of molecularly targeted anti-cancer drugs. However, as was the case with conventional chemotherapies, the effectiveness of these drugs is limited by the emergence of drug-resistant variants. While most cancer therapies are given in combinations that are designed to avoid drug resistance, we discuss here therapeutic approaches that take advantage of the changes in cancer cells that arise upon development of drug resistance. This approach is based on notion that drug resistance comes at a fitness cost to the cancer cell that can be exploited for therapeutic benefit. We discuss the development of sequential drug therapies in which the first therapy is not given with curative intent, but to induce a major new sensitivity that can be targeted with a second drug that selectively targets the acquired vulnerability. This concept of collateral sensitivity has hitherto not been used on a large scale in the clinic and holds great promise for future cancer therapy.

在疾病干预的众多膜蛋白靶标中,G蛋白偶联受体(GPCR)作为人体内最大的膜受体蛋白家族,成为很多药物的重要靶点,其次是离子通道、转运蛋白和激酶等。膜蛋白在细胞信号转导和运输中发挥了关键作用,当前药物研发面临的挑战在于进一步发掘此类膜蛋白的潜在靶点的干预价值,开发治疗性抗体药物。鉴于特异性抗体能够识别膜蛋白的灵敏特性,以及随着基因工程技术的进步,对已有抗体进行加工改造可获得适应多个靶点蛋白的特异性抗体。然而,成功分离特异靶向膜蛋白抗体取决于一系列因素。我们更易研制和识别结构简单且具有长片段胞外区的抗体分子,但对于高难度的靶点蛋白,如GPCR和其他复杂膜蛋白往往难以得到具有活性的候选抗体。目前若要开发针对复杂膜蛋白(如GPCR、离子通道、转运蛋白和激酶)的抗体药物,必须从抗原靶点设计、抗体筛选策略、先导抗体优化及药物研发模式方面进行考虑。深入研究靶标膜蛋白的结构有助于推进治疗性抗体药物的开发进程。本文概述了抗体靶向复杂膜蛋白的优势和挑战,以及膜蛋白抗原制备和抗体研发策略的最新进展。
