  • 根据欧洲议会和欧盟理事会第1107/2009号条例(EC)的规定,欧盟食品安全局(EFSA)指导性文件,对评估植物保护产品(PPPs)及其转化产物暴露在土壤中的活性物质提供了指导。欧盟食品安全局(EFSA)针对欧盟委员会根据欧洲议会和欧盟理事会第178/2002号条例(EC)的第31条提出的问题,制定了该指导性文件。该指南适用于评估所有潜在需要评估生态毒理效应的浓度类型,例如在不同深度和不同时间窗口期下土壤中总浓度和孔隙水中的浓度。目前的指南同时考虑了稳定优势作物和一年生作物。推荐的暴露评估过程分为四个层次。为促进在监管过程中有效使用分层方法,特开发了用户友好型软件工具。在暴露评估的更高层次,可能包括作物截取和随后在作物冠层的消散。模拟这些过程的模型是协调一致的。此外,开发了易于使用的工作台,用于冲洗掉被作物冠层截取的小部分剂量,这应该与简单分析模型结合使用。关于特定物质的模型输入,该指南通常遵循先前的文件;但是,该指南包含了对针对某些特定物质参数的新的指导。

    • Sunflower oil is an active substance for which, in accordance with Article 23(3) of Regulation (EC) No 1107/2009, the European Commission received an application from Institut Technique de l’Agriculture Biologique (ITAB) for approval as a ‘basic substance’. Regulation (EC) No 1107/2009 introduced the new category of ‘basic substances’, which are described, among others, as active substances, not predominantly used as plant protection products but which may be of value for plant protection and for which the economic interest in applying for approval may be limited. Article 23 of Regulation (EC) No 1107/2009 lays down specific provisions for consideration of applications for approval of basic substances. In March 2013, the European Commission requested the European Food Safety Authority (EFSA) to provide scientific assistance with respect to the evaluation of applications received by the European Commission concerning basic substances. By a further specific request, received from the European Commission on 4 March 2016, EFSA was asked to organise a consultation on the basic substance application for sunflower oil, to consult the applicant on the comments received, and to deliver its scientific views on the specific points raised in the format of a reporting table within three months of receipt of the specific request. A consultation on the basic substance application for sunflower oil, organised by EFSA, was conducted with Member States via a written procedure in September – November 2015. Subsequently, EFSA also provided comments and the applicant was invited to address all the comments received in the format of a reporting table and to provide an application update as appropriate, within a period of 30 days. The current report summarises the outcome of the consultation process organised by EFSA on the basic substance application for sunflower oil and presents EFSA’s scientific views on the individual comments received in the format of a reporting table.

    • 中国科学院华南植物园农业及资源植物研究中心科研人员从鼎湖山土壤来源的一株放线菌Streptomyces sp. SC0581代谢产物中,获得4个具有显著糜蛋白酶选择性抑制活性的环酯肽类化合物(Dinghupeptins A-D),首次运用量子化学DFT理论计算阐明了这些化合物的三维结构,并通过酶动力学分析和分子对接实验探讨了这些活性分子的作用机制和结合位点。   化合物Dinghupeptins A和B分子中具有特征性的Ahp环结构,该类环酯肽家族庞大,大部分存在于蓝藻中,并多具有丝氨酸蛋白酶抑制活性,是丝氨酸蛋白酶生物功能研究的潜力天然分子探针,受到药物化学、天然产物化学和有机合成化学等研究领域的广泛关注。该系列化合物三维结构的分析方法和酶抑制机制的阐明,对环酯肽化学生物学功能及其相关研究具有重要意义。   相关研究结果已发表在国际学术期刊Journal of Natural Products(J.
