FFAGLDD amine salt is MMP9 selective cleavage peptides, which used for cytosolic delivery of Doxorubi-cin (DOX) and achieve temporally and spatially controlled slow drug delivery and release.

Spike Binding Peptide 1 (SBP1), representing amino acids 21-43 of angiotensin-converting enzyme 2 (ACE2), has been utilized in a novel approach involving lipid nanoparticles (LNPs) encapsulated with oseltamivir phosphate and conjugated to SBP1. This formulation aims to investigate the possibility of achieving a controlled, long-term in vivo release of oseltamivir phosphate. Furthermore, a 2% concentration of SBP1 immobilized on crosslinked networks composed of hydroxy acrylate and ethylxanthate ethyl acrylate has demonstrated enhanced in vitro efficiency in capturing the spike glycoprotein of severe acute respiratory coronavirus 2 (SARS-CoV-2), also referred to as the surface glycoprotein.

FFAGLDD TFA is an MMP9 selective cleavage peptide, which is used for the cytoplasmic transfer of doxorubicin (DOX) to realize the controlled slow drug delivery and release.

FFAGLDD is a peptide selective for MMP9 cleavage, utilized for the cytosolic delivery of Doxorubicin (DOX) to achieve controlled, gradual drug delivery and release both temporally and spatially.
