This guide summarizes the major steps of the compound selection and ordering process in Mcule. If you have any questions, feel free to contact us at firstname.lastname@example.org.
The Purchasable compounds collection of Mcule contains over 6 million unique structures and 10 million purchasable products. To keep our database as up-to-date as possible we have developed batch and live handlers that can automatically update stock availability information for millions of products per day. This makes the Mcule database the most up-to-date database of screening compounds currently available. Our compound registration system (Mcule Advanced Curation) includes over 80 steps and 150 substeps including normalization, preparation steps and structural checks. This unique registration system filters out the majority of problematic structures including drawing errors and stereochemical problems. To search this large chemical space we have developed efficient and fast searching tools to help you finding the right compounds for your drug discovery project. Below we list the various searching options you can select in Mcule.
You can use this option to quickly find specific compounds/chemicals or close analogs of a single query compound in the Mcule database.
Searching in over 6M purchasable compounds (Mcule database).
With this option you can run exact searches with multiple query molecules. It can be useful for ordering a set of ligands e.g. virtual screening hits. You can paste or upload structures in multiple formats, such as Mcule IDs, InChI or SMILES strings, InChIKeys and even SDF files and use them as queries in the search.
If you have multiple hits containing common structural elements (e.g. multiple analogs of the same scaffold), it makes sense to include all your hits in a single search as multiple queries. Depending on the scoring method used, the searching algorithm will retrieve hits that are most similar to your query molecules. Best scoring method will retrieve the similarity score to the most similar query molecule. Average scoring method will calculate an average similarity score to all query molecules.
Searching for Mcule IDs is the most straightforward and effective way to retrieve a set of molecules from the Mcule database. For example, if you have downloaded the Purchasable compounds collection from our Database Download page, and you want to come back for purchasing some compounds, you can paste Mcule IDs in the below form. All exported SDF files that you download from Mcule contain the corresponding Mcule IDs as a separate SDF field. If you have both a list of Mcule IDs and SDF, it is preferable to use the Mcule ID to retrieve compounds, as it more clearly identifies the structures.
The Mcule technology revolutionizes compound selection either for virtual screening or for screening library design. The Workflow Builder can be used to build custom screening and filtering workflows by putting together powerful and advanced cheminformatic and molecular modeling tools like LEGO bricks. It can be used to run structure-based and ligand-based virtual screening workflows and the best hits can be purchased by just a few clicks. It enables the design of screening libraries based on various properties including chemical diversity (large-scale diversity selection) and supplier information (e.g. purity, available stock amount, delivery time, etc.).
In Mcule you can select particular compounds either manually or by using the basic and advanced (smart) searching tools and store them in collections. The owner of a collection can set its privacy level to Private (only users with permission can get access), Unlisted (only people who know the specific URL of the collection can get access), or Public (accessible for everybody). Your search results (set of molecules and associated information) are also automatically stored in collections. Not only the search results but the queries are saved as well, so that you can go back and refine your queries until you get the optimal search results. Molecule collection can be stored, deleted, modified, merged, imported, exported and shared with your colleagues. Collections can be visualized in multiple ways together with associated data such as various properties, search and calculation results. Tables can be quickly sorted by these properties. Uploaded compounds are also stored in collections and can be used as input for any searches (all associated data incl. phys-chem properties will be automatically generated).
The Mcule database contains over 6 million unique purchasable compounds and 10 million corresponding products. All these compounds can be purchased by clicking on the orange Quote buttons placed next to particular compounds or in the top right corner of collections. Then you can provide basic information required for quote calculation in the Quote form and depending on your price plan you will be able to choose between Instant Quote and Next-Day Quote. If you select Instant Quote, the best price and fastest delivery quotes will be calculated on-the-fly. You can then fine-tune these quotes based on Effective price, stock availability and purity information. After you finalized your quote, you can save it and export it in PDF or Excel formats. You can go back any time when you are ready to place the order. Optionally, you can specify a Purchase Order number and upload a PO file issued by your company / institution. After you placed the order, you can track its status online.
In the quote form you can specify the preferred and the acceptable minimum amounts per compound. For example, if you would like to order 20 mg but at least 5 mg of a compound, then you should set these values as preferred and acceptable minimum, respectively. You can also set the minimum required purity for the products. Please note that for most screening compounds the guaranteed minimum purity is 85-90-95%, depending on the catalogs. You can request the compounds in standard or custom vials (powders) or plates (DMSO solutions). Our recent development now allows to implement any customer-defined formatting option to Instant Quote and we can implement it for you in a few days. To enable custom delivery formats in Instant Quote, please contact us at email@example.com. In the Quote form, you can also specify which catalogs should be included / excluded in the quote calculation. Catalogs are grouped based on stock availability information: Known stock amounts refers to at least weekly updated information, while for Stock catalogs, high availability rate is guaranteed but current amounts are not provided by the supplier. The maximum delivery time (in working days) can be also set.
Instant Quote utilizes a unique price optimization algorithm which calculates the best price and fastest delivery quotes by comparing and optimizing compound prices, supplier discounts, small order fees, delivery costs, customs duties and reformatting options. Since the same compound is typically available from multiple suppliers and there are many parameters to consider during quote generation, the manual price and delivery time optimization could be very challenging even for a relatively small order: the number of possible quotes for 10 compounds each available from 5 suppliers, would be 510. Additionally, requesting stock availability information is time-consuming especially when the information has to be requested by email.
Our unique quote generation algorithm first automatically checks the stock availability for your selected suppliers. For almost 6M products we have access to the supplier's current stock levels that makes Instant Quote generation particularly reliable.
In the next step, our robust optimization algorithm finds the best product matches by minimizing the total price and the delivery time. Instant Quote generation typically takes 1-2 minutes even for thousands of compounds. After the optimization algorithm finishes the generated quotes will appear in the Quote list view.
After analyzing the summary table in Quote list view, you can click on “See details” to see the break down of the total price of the individual quotes and most importantly you can fine-tune the quote by excluding compounds based on their effective price, stock availability and purity data. After you selected the products you want to remove, click on the “Remove selected and recalculate” button and a new quote will be generated for the remaining products on-the-fly.
After finalizing your quote, you can place an order by clicking on the orange Order button. Please note that the stock availability of the compounds can change any time. If you go back to a previously saved quote, the stock availability of a compound might have fallen below the acceptable minimum amount. In such a case, the particular product is displayed after clicking on Order. If your quote is older than a few days, we suggest to re-run Instant Quote to make sure you place an order based on the most recently updated stock information. You can specify a PO number which we will use throughout the whole procurement and delivery process. You will be asked to either upload your PO file, send it later or place an order without a PO file. Please note that if you choose to place an order without a PO file, we will start processing your order and any PO files sent to firstname.lastname@example.org will be neglected. We also ask for the shipping and billing details, including an EU VAT number for EU customers.
After placing an order online, you can track its status by checking its unique URL. You can also request status updates and we will email you when the status of your order gets updated.
You can request custom formatting (custom vials / plates, extra weighting, DMSO solutions, dry ice shipping) and Mcule delivers the compounds as requested. Please note that any customer-defined formatting option can be implemented to our quote calculation algorithm and listed as a new delivery format option in your personal Instant Quote account.
Your ordered products will be delivered to you as a single package. You do not need to deal with a lot of chemical suppliers, we collect all products and send you a consolidated package.
We provide complete EU and US customs clearance service (customs duties and taxes are paid by Mcule). Mcule does not charge any hidden customs costs to its customers. Additionally, our advanced service enables door-to-door delivery, meaning that you will not be contacted by any customs brokers, just get the package delivered to your door.
