Gathers information on the sequence, structure, function, and pharmacology of spider-venom toxins. ArachnoServer is an online database that allows advanced searches of toxin information, browsing, as well as similarity searches using BLAST. Each toxin record is displayed in a single page and a toxin's structure can be dynamically visualized. This repository introduces a bioinformatics pipeline (named Tox|Note) that automatically identifies and analyzes toxins in assembled venom-gland transcriptomes.


Consists of chemical information and four types of well-developed assays associated with the four events of the adverse outcome pathway (AOP) for skin sensitization reported by Organization for Economic Cooperation and Development (OECD). SkinSensDB provides chemical-related informations which include the CAS number, IUPAC name, INCHI, INCHIKEY, formula, SMILES, hydrogen-bond acceptor, hydrogen-bond donor, molecular weight and topological polar surface area (TPSA). This database also offers external links to PubChem database and SDF files for 2D and 3D structures.


A collection of toxic compounds from literature and web sources. The current version of this database compiles about 60,000 compounds and their structures. These molecules are classified according to their toxicity, based on more than 2 million measurements. The SuperToxic database provides a variety of search options like name, CASRN, molecular weight and measured values of toxicity. With the aid of implemented similarity searches, information about possible biological interactions can be gained.

Canary Database

Is a result of collaboration between human health and animal health professionals to explore the linkages between animal disease events and human environmental health risks. The Canary Database is a compilation of curated peer-reviewed research articles related to the use of animals as sentinels of human health hazards. This database contains information added by trained curators in addition to bibliographic records from MEDLINE and other well-known databases. The database includes studies of wildlife, companion, and livestock animals, where either the exposure or the health effect could be considered potentially relevant to human health.

HSDB / Hazardous Substances Data Bank

Provides information in areas such as chemical substance identification, chemical and physical properties, safety and handling, toxicology, pharmacology, environmental fate and transformation, regulations, and analytical methodology. HSDB focuses on the toxicology of potentially hazardous chemicals and particularly on human exposure, industrial hygiene, emergency handling procedures, environmental fate, regulatory requirements, nanomaterials, and related areas.

CCRIS / Chemical Carcinogenesis Research Information System

Contains over 9,000 chemical records with carcinogenicity, mutagenicity, tumor promotion, and tumor inhibition test results. CCRIS’s data are derived from studies cited in primary journals, current awareness tools, National Cancer Institute (NCI) reports, and other special sources. CCRIS is a scientifically evaluated and fully referenced data bank, developed and maintained by the NCI. The database provides historical information from the years 1985 - 2011.


A Web-based platform for collecting and storing toxicological structural alerts from literature and for virtual screening of chemical libraries to flag potentially toxic chemicals and compounds that can cause adverse side effects. An alert is uniquely identified by a SMARTS template, a toxicological endpoint, and a publication where the alert was described. Additionally, the system allows storing complementary information such as name, comments, and mechanism of action, as well as other data.

OCHEM / Online Chemical Modeling Environment

A web-based platform that aims to automate and simplify the typical steps required for QSAR modeling. The platform consists of two major subsystems: the database of experimental measurements and the modeling framework. A user-contributed database contains a set of tools for easy input, search and modification of thousands of records. The OCHEM database is based on the wiki principle and focuses primarily on the quality and verifiability of the data. The database is tightly integrated with the modeling framework, which supports all the steps required to create a predictive model: data search, calculation and selection of a vast variety of molecular descriptors, application of machine learning methods, validation, analysis of the model and assessment of the applicability domain.

CREST / Chemical attributes, Regulatory approaches and Experimental STudies from a mixture toxicology perspective

Gathers information about experimental mixture studies. CREST is a public repository organized through three main categories: literature, datasets and chemicals. Searches can be made by studies or by chemicals using their name or their standard international chemical identifiers (Std InChIs). The database gives access to external links towards the corresponding literature or to content that can be exported in tab-separated text format. The database is part of the MixTox TRI (towards regulatory implementation) project.

TRI / Toxics Release Inventory

Offers a source of environmental performance information about firms. TRI requires all manufacturing facilities operating under SIC codes 20-39, with 10 or more employees, to submit a report of their annual on-site releases and off-site transfers of each of over 300 specified toxic chemicals. TRI is a set of publicly available databases containing information on releases of specific toxic chemicals. The database allows investors to benchmark a firm’s environmental performance and make comparisons of performance over time as well as across firms.


Allows users to create dynamic maps that show where Toxics Release Inventory (TRI) chemicals are released. TOXMAP provides direct links to information about the chemicals in TOXNET. It provides customized chemical and/or region-specific searches of National Library of Medicine’s (NLM’s) bibliographic biomedical resources. The database uses chemical and geographic terms from the displayed map to search bibliographic databases, integrates geographically coded data from other sources, and be easy to navigate and understand.

ITER / International Toxicity Estimates for Risk

Contains 620 chemical records with information on toxic risk levels and risk values, carcinogen classifications, and dose-related information. ITER presents a comparison of the international risk assessment data via summary tables with the information from each parent organization listed next to each other. It explains differences in risk values derived by different organizations. The database includes data from the EPA, Health Canada, the National Institute of Public Health and the Environment of the Netherlands, and other organizations.


Contains information on the epidemiology of occupational or job task related diseases. Haz-Map provides links to information about industrial hygiene related to occupational exposure to a specific list of toxic chemicals. The database is useful for health and safety professionals, as well as consumers who wish to research the various health effects of exposure to chemicals in the workplace. It provides a link between these jobs or hazardous tasks and their associated occupational diseases and symptoms.

Tox Town

Uses colors, graphics, sounds and animations to add interest to learning about connections between chemicals, the environment, and the public's health. Tox Town is designed to give information on (i) everyday locations where you might find toxic chemicals, (ii) non-technical descriptions of chemicals, (iii) links to selected, authoritative chemical information on the Internet, (iv) how the environment can impact human health, and (v) Internet resources on environmental health topics.
