  • New home page design

    A week ago we have moved to the new home page design. So now you can experience even more user-friendly tool-bar interface. Please visit http://www.chem-space.com to search in 100 million building blocks, fragments, and screening compounds.

  • QED sets

    Quantitative Estimate of Druglikeness (QED) is an integrative score to evaluate compounds’ favorability to become a hit. We have selected 210,000 compounds with high QED score (over 0.9) from a Chemspace Screening set. You can download these in-stock high-QED compounds on the website. For make-on-demand high-QED set please contact us at info@chem-space.com Please visit https://chem-space.com/compounds for more information.

     

  • Meet us at the 16th Annual Discovery on target

  • Framework-derived set

    At Chemspace, we struggle to provide our users with a number of tools and services to simplify the compound selection process. These include fast online similarity and substructure search, compound sets, and custom library preparation, - to name a few.

    Framework-derived set is another approach to surf the Chemspace database. The set comprises over 6 million screening compounds that belong to one of 72,000 selected diverse Bemis-Murcko frameworks. At least 20 compounds share the same frameworks. 

     

  • Tributyl stannanes

    Aryl stannanes have been widely utilized in Stille coupling that is similar to Suzuki coupling. The interest in these tin-organic compounds is because of their large variety and higher stability...

  • Cyclobutyl Azetidines

    A pair of sunglasses is what most of us need every day. Looking at chemical structures, one can imagine sunglasses as a two ring system. This week we present molecules with two four-member rings: azetidine and cyclobutane...

  • Acquisition for Compound Screening Libraries

    Chemspace is delighted to exhibit at Innovation in Design and acquisition for Compound Screening Libraries Conference (May 15 - 16, Benjamin Franklin Institute of Technology, Boston, MA, United States), organized by SCI’s Fine Chemicals Group.

  • Sulfonyl Chlorides. Part 3

    To choose molecules of this week, we searched for those with simultaneously present three key features: the smallest cycle, cyclopropyl ring; the smallest substituent, fluorine; and our favorite functional group, sulfonyl chloride...

  • Events Calendar 2018

    The updated list of Chemspace events.

  • Nonclassical phenyl ring bioisosteres

    Shape… What can one say about shape? Every little thing got it or at least looks like something else. Shape is extremely important as it influences the chemical properties...

  • Difluorocyclopropanes

    Another small group for drug discovery.

    When medicinal chemists design a lead they want to decorate it with small functionalities, for example, oxetane or sulfoximine. This time we pay...

  • Sulfonyl Chlorides. Part 2

    When a movie becomes successful producers often start thinking about creating a sequel or even a saga… As for sulfonyl chlorides, you should be thinking about a multi season TV show that tells about the sulfonyl chlorides and their nearest analogues...

  • Sulfonyl Chlorides. Part 1

    It is an interesting fact that the well-known class of sulfonyl chlorides is still one of the most wanted Building Blocks for many researchers. Is it because of a highly reactive sulfonyl chloride moiety that reacts with anything you want and can rapidly produce the corresponding sulfonic acids, sulfonic esters, or sulfonamides?...

  • Merry Christmas and a Happy New Year!

    The Chemspace Team sincerely wishes Merry Christmas and a Happy New Year to all our customers, suppliers, and partners!

  • Very Unusual Amino Acids

    When somebody, especially not a chemist, talks about amino acids they typically mean the food additives what bodybuilders use for growing their muscles. But our, chemists, view is absolutely different and under amino acids we see molecules that cannot be bought in a drugstore. Our amino acids help pump the main “muscle” of any researcher - the brain!...

  • Morpholine analogues

    The molecules of this week are definitely recognized as morpholines! Not just morpholine derivatives, but rather constrained analogues with a geometric construction in the cycle. Why did we select them as "molecules of the week"? It is simple: morpholine is one of the most popular fragments in medicinal chemistry and is among TOP 30 most frequently used ring systems for small molecule drugs....
