Due to the discontinuation of support by ChemAxon for academic websites, SwissBioisostere is currently being updated to remove its dependency on their software. At the same time, we are improving the platform to include a larger number of compounds. As a result, the website will be temporarily unavailable for the next few weeks. If you would like to be notified when the website becomes available again, please contact us through the forum and include your email address. We will get back to you as soon as the updated website is online.
