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.
The Protein Data Bank (PDB) is a repository for stractural data of biological macromolecular structures (mainly proteins, but also DNA & RNA). PDB 101 provides very good educational resources.
The data, typically obtained by X-ray crystallography or NMR spectroscopy and are freely accessible via the websites of its member organisations (PDBe, PDBj, and RCSB). The PDB is overseen by an organization called the Worldwide Protein Data Bank, wwPDB.
The Research Collaboratory for Structural Bioinformatics (RCSB) is dedicated to improving our understanding of the function of biological systems through the study of the 3-D structure of biological macromolecules.

Scopus offers the most comprehensive overview of research results in science, technology, medicine, social sciences and humanities. Scopus covers more than 25 100 peer-reviewed journals by more than 7,000 publishers, 580 book series, as well as 9 million conference papers. In total, there are more than 77 million records, amongst them over 71 million records post 1969, with complete references.
Numerous tools allow you to analyze visualize and follow up on research results.
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.
The world's largest database for physical and chemical data in the fields of physics, physical and inorganic chemistry, materials science and engineering.
SpringerMaterials is a source for physicochemical properties of inorganic and organic compounds and their mixtures, elements, alloys, ceramics, polymers, plastics, and semiconductors. It consists of six major parts: Landolt-Börnstein Series, Linus-Pauling Files, Adsorption Database, Polymer Thermodynamics Database, Thermophysical Properties Database and MSI Database including a set of advanced functionalities for visualizing and analyzing data called "SpringerMaterials Interactive".
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.
