PubChem
收藏资源简介:
PubChem is the world's largest collection of freely accessible chemical information. Searches can be performed via a number of descriptors such as name, molecular formula and structure. Information is provided for chemical and physical properties, biological activities, safety and toxicity information, patents, literature citations and more. PubChem is organized as three linked databases within the NCBI's Entrez information retrieval system. These are PubChem Substance, PubChem Compound, and PubChem BioAssay. PubChem also provides a fast chemical structure similarity search tool.
PubChem是全球规模最大的免费开放化学信息资源库。可通过名称、分子式、分子结构等多种描述符执行检索操作。该库提供理化性质、生物活性、安全与毒性信息、专利文献、学术引用等多维度内容。PubChem隶属于美国国家生物技术信息中心(NCBI)的Entrez信息检索系统,下设三个相互关联的数据库,分别为PubChem物质数据库、PubChem化合物数据库及PubChem生物活性测定数据库。此外,PubChem还搭载了高效的化学结构相似性检索工具。
