Brainpeps®

Brainpeps® is a resource of blood-brain barrier properties of peptides. This database is managed by Ghent University. Based upon your input, this search page will give you all information (structure, method, responses, physicochemical properties and related literature). The database is linked to a manuscript entitled "Brainpeps: the blood-brain barrier peptide database", in which the BBB methods and responses are clarified and correlated to each other.

Sequence, Trivial name, Molecular formula, Method, Response, Literature
Peptide
Sequence (1-letter or 3-letter code)
For the 1-letter and 3-letter sequences, the nomenclature recommended by the IUPAC-IUBMB Joint Commision on Biochemical Nomenclature is used: Nomenclature and Symbolism for Amino Acids and Peptides. The used nomenclature for unnatural amino acids can be found on the following link: Nomenclature unnatural Amino Acids.
, trivial name, abbreviation, molecular formula The molecular formula is entered using the following template, maintaining the order of the atoms: CxHxNxOxSxClx. If no S- or Cl-atoms are present, they don’t need to be filled in.
