Inhibitor peptide that selectively disrupts binding of the AMPA receptor subunit GluA2 (at the C-terminal PDZ site) to protein interacting with C kinase (PICK1). Does not affect binding of GluA2 to GRIP or ABP and does not increase AMPA current amplitude or affect long term depression (LTD).

Bursin is a peptide that can be isolated from the bursa of Fabricius of chicken. Bursin induces the phenotypic differentiation of mammalian and avian B precursor cells. Bursin also increases cyclic guanosine monophosphate in cells of the human B-cell line Daudi, its derivatives are able to protect against infection by amplifying the immune response induced by H9N2.

Lecithins, egg can be used as an excipient. Pharmaceutical excipients, or pharmaceutical auxiliaries, refer to other chemical substances used in the pharmaceutical process other than pharmaceutical ingredients. Pharmaceutical excipients generally refer to inactive ingredients in pharmaceutical preparations, which can improve the stability, solubility and processability of pharmaceutical preparations. Pharmaceutical excipients also affect the absorption, distribution, metabolism, and elimination (ADME) processes of co-administered drugs.
