MolMeDB is an open chemical database that focuses on ligand-membrane and membrane protein-ligand interactions.
We explore how ligands interact with biological membranes...
Understanding these interactions is key to evaluating molecular activity, bioavailability, and pharmacokinetics. Ligand-membrane interactions can be described through partitioning, permeability, and positioning, which define how compounds cross or embed within lipid bilayers. At MolMeDB, these data are collected from experimental studies, molecular simulations, and computational prediction methods, offering an integrated resource for researchers.
...and ligands interact with membrane proteins
Not only membranes play an essential role, but also membrane proteins. Membrane proteins - such as transporters, ion channels, and receptors - actively control uptake, efflux, and cellular signalling. Together with passive diffusion, these protein-mediated processes shape the behavior of molecules in living systems. Understanding both pathways is crucial for predicting the efficacy, safety, and selectivity of drugs. MolMeDB combines these aspects by integrating data on small molecules, membranes and membrane proteins, providing a comprehensive resource for exploring molecular behavior in biological contexts.
How do compounds interact with membranes?
- they are attracted to membranes
- they partition to membranes
- they reside in specific positions on membranes
- they penetrate through membranes
- they change the structure of membranes
