    EphA2是一种酪氨酸激酶受体,被认为是癌症中有希望的靶标。不同的方法被用于靶向EphA2受体,大量的临床前数据证明了该受体在临床肿瘤学中用于诊断和癌症治疗的潜在开发。包括免疫疗法。
    在这篇综述中,我们总结了涉及EphA2靶向癌症的最新专利。为此,我们使用了2018年至今的专利数据库专利范围。当在同行评审的期刊上发表时,考虑本发明的临床前和临床数据。此外,在可用时,包括clinicaltrial.gov标识符(NCT编号).为了更容易和更直接的阅读,我们根据性质将专利分为不同的类别(适体,小分子,抗体,肽,抗原和嵌合抗原受体)的发明在临床肿瘤学中利用EphA2。
    尽管存在大量化学上多样化的药物,目前尚无批准的靶向EphA2的抗癌药物.然而,这些知识产权,其中一些有强有力的临床前证据支持,保持希望,在它被发现三十多年后,我们将最终看到首个被批准用于临床肿瘤学的EphA2靶向剂.
    UNASSIGNED: EphA2 is a tyrosine kinase receptor and is considered a promising target in cancer. Different approaches are used to target EphA2 receptor and a lot of preclinical data demonstrate the potential exploitation of this receptor in clinical oncology for diagnosis and cancer therapy, including immunotherapy.
    UNASSIGNED: In this review we summarize the recent patents involving the EphA2 targeting in cancer. For this aim we used the patents database Patentscope covering the time period of 2018 - present. Preclinical and clinical data of the inventions were considered when published on peer reviewed journals. Moreover, the clinicalTrial.gov identifiers (NCT numbers) were included when available. For an easier and more immediate reading we classify the patents in different categories considering the nature (aptamers, small molecules, antibodies, peptides, antigens and chimeric antigen receptors) of the inventions exploiting EphA2 in clinical oncology.
    UNASSIGNED: Despite the availability of a plethora of chemically diverse agents, there are no approved anticancer drugs targeting EphA2 yet. However, these intellectual properties, some of which supported by strong preclinical evidence, keep the hope that, after more than thirty years from its discovery, we will finally see the first EphA2 targeting agent approved in clinical oncology.

    COVID-19大流行表明,目前纯粹由市场驱动的药物发现和开发方法不足以推动公平获得新疗法,或者作为回应,流行病。世界卫生组织正在谈判一个由公平驱动的新全球框架,以支持大流行的防范和应对。一些人认为全球知识产权(IP)系统本身就是问题的一部分,并提出了一种纯粹的开放科学方法。在这篇文章中,我们讨论了如何利用现有的知识产权框架和合同协议来创造权利和义务,以便在未来产生更有效的全球应对措施。借鉴在COVID登月计划中获得的经验,纯粹的开放科学合作,和ASAPAViDD药物发现联盟,使用混合动力,开放科学的分阶段模型,专利申请和合同协议。我们得出的结论是,“直接到仿制药”的药物发现在某些领域是合适的,以及有针对性的专利保护,再加上开放式许可,可以为市场力量失败的治疗领域提供负担得起的公平获取途径。扩展数据包含我们的模型IP策略的副本,这可以作为其他发现努力的模板,以确保他们的候选药物可以开发为全球公平和负担得起的获取。
    药物发现和开发组织通常通过申请候选药物的专利来收回他们在这个风险和昂贵的过程中的投资,如果授予,让他们在制造上有时间限制的垄断,药物的销售或许可。这意味着他们可以协商价格和分销条款,这在全球范围内造成了访问扭曲。在另一种“开放科学”方法中,研发组织在没有申请专利的情况下公布了关于潜在药物的所有信息,这意味着任何人都可以利用这些知识来制造和销售药物,而研发组织无法控制它的定价或分配方式。在大流行中,必须通过将药物运送到最需要的地方来迅速遏制快速传播的病毒。这需要创新和全球准入,但这在两种模式中都被扼杀了——第一种是由于专利滥用,第二,因为缺乏控制可能会危及最有效的发展。作者分享了一个模型,该模型通过基于“最低防御性专利”创建“最大许可许可”来优先考虑全球公平和负担得起的定价。他们解释了他们的建议的实践和生物伦理背景,并分享了一个集体管理知识产权和许可协议的例子,该协议正在人工智能驱动的结构化抗病毒平台(ASAP)中心的大流行准备工作中使用。
    The COVID-19 pandemic demonstrated that the current purely market-driven approaches to drug discovery and development alone are insufficient to drive equitable access to new therapies either in preparation for, or in response to, pandemics. A new global framework driven by equity is under negotiation at the World Health Organization to support pandemic preparedness and response. Some believe that the global intellectual property (IP) system itself is part of the problem and propose a purely Open Science approach. In this article, we discuss how existing IP frameworks and contractual agreements may be used to create rights and obligations to generate a more effective global response in future, drawing on experience gained in the COVID Moonshot program, a purely Open Science collaboration, and the ASAP AViDD drug discovery consortium, which uses a hybrid, phased model of Open Science, patent filing and contractual agreements. We conclude that \'straight to generic\' drug discovery is appropriate in some domains, and that targeted patent protection, coupled with open licensing, can offer a route to generating affordable and equitable access for therapy areas where market forces have failed. The Extended Data contains a copy of our model IP policy, which can be used as a template by other discovery efforts seeking to ensure their drug candidates can be developed for globally equitable and affordable access.
    Drug discovery and development organizations usually recoup their investment in this risky and expensive process by filing patents on drug candidates which, if granted, give them a time-limited monopoly on the manufacture, sale or licensing of the drug. This means they can negotiate its price and terms of distribution, which creates distortions in access globally. In an alternative ‘Open Science’ approach, R&D organizations publish all the information about a prospective drug without applying for patents, meaning that anyone can use this knowledge to make and sell the drug, while the R&D organizations have no control over how it is priced or distributed. In a pandemic, fast-spreading viruses must be rapidly contained by delivering drugs to where they are most needed. This requires innovation and global access, but this is stifled in both models – in the first because of patent abuses, in the second because the lack of control may jeopardize the most efficient development. The authors share a model that prioritizes globally fair and affordable pricing by creating ‘maximally permissive licenses’ based on ‘minimally defensive patents’. They explain the practical and bioethical background to their proposals and share an example of collective management of intellectual property and licensing agreement that is being used in the AI-driven Structure-enabled Antiviral Platform (ASAP) Center’s Pandemic Preparedness work.

    专利对于将科学发现转移到有益于社会的有意义的产品至关重要。虽然学术界关注引用的数量,以根据其科学价值对学术著作进行排名,“引用的数量与可申请专利的创新的相关性无关。在公开的专利数据中探索专利与学术著作之间的关联,我们建议利用生物学中常用的统计方法来确定基因与疾病的关联.我们说明了他们在与食品安全和生态学高度相关的生物技术趋势相关的专利上的使用,即基于CRISPR的基因编辑技术(>60,000专利)和蓝藻生物技术(>33,000专利)。在时间序列分析中,通过专利数量的意外变化发现了创新趋势。从所有调查专利(~254,000份出版物)引用的全部学术著作中,我们确定了约1,000篇学术著作,这些著作在专利参考文献中统计上明显过度代表,这些著作来自与免疫学有关的不断变化的创新趋势,农业植物基因组学,和生物技术工程方法。检测到的关联与相应创新的技术要求一致。总之,所呈现的数据驱动分析工作流程可以识别创新趋势变化所需的学术著作,and,因此,对于希望评估出版物的相关性超出引用次数的研究感兴趣。
    Patents are essential for transferring scientific discoveries to meaningful products that benefit societies. While the academic community focuses on the number of citations to rank scholarly works according to their \"scientific merit,\" the number of citations is unrelated to the relevance for patentable innovation. To explore associations between patents and scholarly works in publicly available patent data, we propose to utilize statistical methods that are commonly used in biology to determine gene-disease associations. We illustrate their usage on patents related to biotechnological trends of high relevance for food safety and ecology, namely the CRISPR-based gene editing technology (>60,000 patents) and cyanobacterial biotechnology (>33,000 patents). Innovation trends are found through their unexpected large changes of patent numbers in a time-series analysis. From the total set of scholarly works referenced by all investigated patents (~254,000 publications), we identified ~1,000 scholarly works that are statistical significantly over-represented in the references of patents from changing innovation trends that concern immunology, agricultural plant genomics, and biotechnological engineering methods. The detected associations are consistent with the technical requirements of the respective innovations. In summary, the presented data-driven analysis workflow can identify scholarly works that were required for changes in innovation trends, and, therefore, is of interest for researches that would like to evaluate the relevance of publications beyond the number of citations.

    Polyphenols are a group of naturally occurring compounds that have intriguing biological activities. Among these compounds is rutin, a polyphenolic flavanol found in many plants, including passion flowers, buckwheat seed, fruits and fruit rinds, and citrus fruits (such as orange, grapefruit, lemon, and lime). Various studies have demonstrated rutin to possess antibacterial, antifungal, antiallergic, anti-inflammatory, anti-diabetic, anti-adipogenic, anti-carcinogenic, anti-apoptotic, anti-osteoporotic, radioprotective, gastroprotective, neuroprotective, and nephroprotective activities. Despite its benefits, rutin\'s therapeutic applicability is severely limited due to its low water solubility, sensitivity to oxidation, and dissolving rate. However, these problems can be overcome by employing an efficient delivery approach. An extensive number of nanocarriers can be developed for medicinal use if pre-clinical as well as human-clinical studies are completed. The current review presents an overview of effective rutin nano-formulations for targeted therapy in various health disorders. This review article discusses the clinical evidence, current status, as well as future opportunities of rutin nanocarriers for increasing rutin\'s bioactivity for possible medicinal uses.
