Paper Design of cyclic RGD-conjugated Aib-containing amphipathic helical peptides for targeted delivery of
Peptide PI-acetamide
Delivery Success Class no
In Vivo Flag no
Uptake Confirmed yes
Label Confidence high
In Vitro Functional Effect no
Endosomal Escape Evidence
Peptide Concentration 1.0 µM
Rna Concentration 10 nM
Mixing Ratio 100
Formulation Format electrostatic peptide/siRNA complex
Formulation Components cRGDfC–MAP(Aib) conjugate peptide + siRNA (complex formed by electrostatic interaction)
Size Nm
Zeta Mv
Model Scope in_vitro
Model Type in vitro
Cell Lines Or Primary Cells A549; A549-Luc (luciferase-expressing A549)
Animal Model
Administration Route
Output Type reporter knockdown (luciferase)
Output Value No knockdown (relative luciferase ~control) at 24 h post-treatment
Output Units
Output Notes Uptake: delivers fluorescence-labeled siRNA into A549 (lower than PI), but did not suppress luciferase expression under RNAi assay conditions.
Toxicity Notes LDH release ~17% at 1.0 µM/10 nM (ratio 100) after 24 h; reduced to ~12% (ratio 50) and ~7% (ratio 20) when lowering peptide/siRNA ratio (reported alongside PI trends).
