Natural Compound and Natural-Like Compound Database

Natural Products


Natural products are chemical compounds found in nature originating in plants, animals, and microbial and marine sources. Such products are important in the cosmetics, food, and nutrition industries because of their many beneficial properties and positive commercial image. Many active pharmaceutical compounds are natural products or derivatives of natural compounds, and it is estimated that some 40% of the drugs marketed today are derived from chemical structures found in nature. Well known examples include the anticancer agent paclitaxel (sold as Taxol), originally extracted from the Pacific yew tree; the heart medicine digoxin, extracted from the foxglove plant; and aspirin, derived from a precursor found in the leaves of the willow tree, and used for its health benefits for thousands of years. Typically, such natural compounds have better bioavailability than synthetic compounds.

In recent years there has been a revival in interest in exploring and testing natural compounds in lead discovery, as they often present a wide range of novel and exploitable structural motifs. Examples include the study of marine natural products as potential antimicrobial agents, and plant extracts as antifungal agents. There are many free and paid-access databases of natural products. These databases extract information from the scientific literature and other sources and they usually contain detailed information about each compound. However, such databases typically lack information about commercial sources of samples of these natural products, and lead discovery scientists are often frustrated by the low success rate of sourcing samples for screening.

S. O'Hagan and D.B. Kell at the University of Manchester recently published an interesting comparison of MolPort and proprietary Natural Product database data, with the goal of creating available-to-purchase natural product diversity sets. In a follow up study authors selected a small library of Natural Products to cover chemical space inexpensively. Please contact us if you are considering purchasing this or a similar natural product set, as we can provide a unique offer to meet your needs.



The MolPort Natural Products Database


The MolPort database of commercially available compounds aggregates the catalogues of reliable chemical suppliers, many of whom also offer natural products. We have collected information on over 10,000 unique natural and over 100,000 natural-like products from our suppliers and have made it available via downloadable files. Some of the natural compounds in our selection are not listed in other commercial natural product databases.

The MolPort natural product files are available for download via our FTP service. You will find them in the 'Natural Products' folder in SDfiles and SMILES formats. Both formats contain the compound structure, the MolPort ID, an identifier for the highest potential class of natural compound, class description, and a link to the dedicated molecule page on molport.com

You can request credentials for your free access to the MolPort FTP service by contacting our Customer Support or by filling and submitting the contact us form.



Natural Product Classification


Upon our request, suppliers classified their natural and natural-like products according to the following ranked classification rules:

Category Abbreviation Description
Naturally sourced NS Sample isolated from a natural source
Genuine natural GN Compound occurs in nature, but the specific product may have been produced synthetically
Natural compound derivatives ND Compound is a derivative of a GN
Natural-like NL Mimetics or analogs

Our files contain information on the highest potential class available.

For example, if a supplier has no evidence of a product occurring in nature, they can classify it as 'natural-like' (NL); however, another supplier may provide a product based on the same molecule, which is sourced from plant extracts and can be classified as 'naturally sourced' (NS). In this case our file will contain the compound category 'naturally sourced' for this molecule.

Note: the actual data on the number of products available for sale may be less due to sold out products and other factors. Also note that the total number of molecules available in our files will be less, since some compounds are often provided by multiple suppliers.



Q/A: Does MolPort have information about the source of natural products?

Some suppliers provide this information, whereas others do not, or at least not for free. Please contact us to discuss your request. Please note that the same compounds from the same supplier can sometimes be sourced from different species, depending on the batch.



Q/A: Does MolPort work with extracts or fractions (mix of compounds)?

No. However, some of our suppliers do.
