Open Chemistry Information Database

PubChem provides information on the chemical and physical properties, biological activities, spectra, patents, health, safety and toxicity data of predominantly small molecules but also some larger molecules such as peptides, carbohydrates, nucleotides and lipids. The database is maintained by the National Center for Biotechnology Information (NCBI) of the National Library of Medicine, which is part of the US National Institutes of Health (NIH). PubChem records are contributed by hundreds of data sources including research organisations, government agencies, chemical vendors, academic publishers and more.


PubMed is a freely accessible bibliographic literature database that lists individual articles from almost 5,000 medically relevant journals. The main focus is on English-language journals, usually from 1966 onwards. PubMed's special feature is the MeSH classification, which is extremely helpful in finding really relevant literature.

PubMed comprises more than 28 million citations for biomedical literature from MEDLINE, life science journals, and online books. Citations may include links to full-text content from PubMed Central and publisher web sites.


PubPharm is a freely accessible search engine for biomedical literature that provides information from MEDLINE, journal articles, preprints, dissertations, conference abstracts, clinical trials and patents.

Not only allows PubPharm standard search by text or structure input, but also has features that are not available in PubMed or Embase: With Drug Overviews, a network visualization of diseases, drugs, and targets can be created. The Narrative Service allows you to search for how one search term influences another. This influence is a directed association like "induces", "decreases", "inhibits", "treats" and "interacts". Furthermore, you can use placeholders, e.g. "ivermectin treats diseases" to list all diseases that can be treated with ivermectin by frequency.

RCSB PDB Protein Data Bank

Spectral Database for Organic Compounds (SDBS)

Freely accessible spectral database for organic compounds

SDBS includes six different types of spectra: electron impact mass spectra (EI-MS), Fourier transform infrared spectra (FT-IR), 1H nuclear magnetic resonance (NMR) spectra, 13C NMR spectra, laser Raman spectra, and electron spin resonance (ESR) spectra. Records include graphical structures and spectra, with peak assignments in many cases. Compounds may be searched by name, molecular formula, molecular weight, CAS registry number, number of atoms/elements, and spectral data.

Most of the spectra were measured at the National Institute of Advanced Industrial Science and Technology (AIST) in Japan.

SpringerNature Experiments

This full-text search portal for four SpringerNature journals not only searches abstracts and therefore finds the right literature using very specific experimental keywords such as experiment type, cell lines, media, inductors or vectors.

The hits obtained can be sorted by relevance, date, quotations or "trends". In addition, the list can be further restricted by filters such as techniques (e.g. Luciferase reporter assay), model systems (e.g. HCT 116 or HEK293T) or video, but also by the usual filters such as year, source and article categories. The underlying information comes from four journals: NatureMethods, Nature Protocols, SpringerProtocols and Protcol Exchange.
