Check out our latest paper Chemical space as a unifying theme for chemistry in Journal of Cheminformatics! Abstract Chemistry has diversified from a basic understanding of the elements to studying millions of highly diverse molecules and materials, which together are conceptualized as the chemical space. A map of this chemical

Check out our latest publication Predicting Polypharmacology with Web-Based Tools in Wiley! Abstract Identifying possible off‐targets is critical during drug development. Estimating polypharmacology can be nowadays performed online thanks to the availability of various web‐based target prediction tools. In this chapter, we review eight such tools that are

Check out our latest paper Diamonds in Chemical Space: The Synthesis of Brexazine in Helvetica! Abstract Here we searched chemical space for small and novel diamond-like, 3D-shaped building blocks, which are very rare but highly valuable for medicinal chemistry because they can increase the natural product likeness of drug molecules

Check out our latest review Chemical Space for Peptide-based Antimicrobials in CHIMIA! Abstract Multidrug-resistant (MDR) bacteria represent a global public health threat, and antimicrobial peptides (AMPs), derived from naturally occurring linear or cyclic peptides, can provide the solution. However, most AMPs are sensitive to proteases and have poor pharmacokinetics. The

Check out our latest paper Stereorandomized Oncocins with Preserved Ribosome Binding andAntibacterial Activity in Journal of Medicinal Chemistry! Abstract We recently showed that solid-phase peptidesynthesis using racemic amino acids yields stereorandomizedpeptides comprising all possible diastereomers as homogeneous,single-mass products that can be purified by HPLC and thatstereorandomization modulates activity, toxicity,
