GALA is a pH-responsive amphipathic peptide consisting of 30 amino acids, which acts as a lung endothelium-targeting ligand. GALA undergoes a conformational transition from random coil to α-helix in an acidic environment at pH 5.0, thereby inducing endosomal membrane destabilization and fusion. GALA-modified liposomes traverse lung endothelial cells via clathrin-dependent endocytosis and transcytosis, and specifically accumulate in the lungs after intravenous injection. GALA significantly promotes the cytosolic release of cargos carried by exosomes, plasmids and liposomes, effectively enhances gene transfection efficiency, and drives gene knockdown of functional macromolecules (such as siRNA) in alveolar epithelial cells (with no significant cytotoxicity at effective concentrations). GALA serves as a critical tool for studies on lung cancer metastasis (e.g., melanoma lung metastasis) and lung-targeted drug delivery systems .

PTBP1-RNA-binding inhibitor (PTBP1 α3-helix derived peptide) P6 TFA is a cell-permeable PTBP1 inhibitor. PTBP1-RNA-binding inhibitor P6 TFA binds to the α3 helix binding site of the PTBP1 RRM1 domain, and disrupts the synergistic RNA-binding effect of the RRM1 and RRM2 domains of PTBP1. PTBP1-RNA-binding inhibitor P6 (TFA) regulates the regulatory pattern of PTBP1-related alternative splicing events, and thus exhibits anticancer potential .

Fmoc-(R)-2-(7-octenyl) Ala-OH is an unnatural Fmoc-protected amino acid and modification module. Fmoc-(R)-2-(7-octenyl) Ala-OH serves as a key building block for all-hydrocarbon cross-linking modification of antimicrobial peptides, and facilitates the generation of stapled peptide derivatives. When introduced into specific sites of the parent peptide, Fmoc-(R)-2-(7-octenyl) Ala-OH effectively increases the α-helix content of the peptide chain, thereby significantly enhancing its antimicrobial activity and proteolytic stability. Fmoc-(R)-2-(7-octenyl) Ala-OH is widely used in research on bacterial infections and the development of related antimicrobial agents . Stapled peptide is a specially chemically modified polypeptide. It locks the peptide chain into a stable α-helical structure by introducing a "staple"-like chemical bridge (usually an all-carbon backbone) at specific positions of the peptide chain.

NSC727447 is a vinyl urea-based allosteric inhibitor of HIV reverse transcriptase-associated RNase H with IC50 values of 2.0 μM and 2.5 μM against HIV-1 and HIV-2 RNase H, respectively, and IC50 values of 100 μM and 10.6 μM against Escherichia coli and human RNase H, respectively. NSC727447 exerts allosteric inhibitory effects mainly by interacting with the region adjacent to α-helix I in the thumb subdomain of the p51 subunit of HIV-1 reverse transcriptase. Cys280, Lys281 and the RNase H primer grip region are involved in its action, and it may inhibit the catalytic activity of RNase H by altering the positioning of nucleic acid substrates or the geometry of the RNase H active site. NSC727447 can be used in studies related to HIV infection, the function of HIV reverse transcriptase RNase H, and allosteric inhibition mechanisms .

Synonyms: Orexin A (17-33) (human, mouse, rat, bovine)
OXA (17-33) (Orexin A (17-33) (human, mouse, rat, bovine)) is the shortest active orexin peptide that selectively targets OX1 (EC50=8.29 nM), with 23-fold selectivity for the OX1 receptor over the OX2 receptor. The activity of OXA (17-33) depends on the Tyr17, Leu20, Asn25, His26 residues and the spatial conformation of the α-helix. OXA (17-33) activates signaling pathways involving inositol-1,4,5-trisphosphate receptor (IP3R), phospholipase D (PL-D) and choline-Sigma-1R, thereby increasing the cytoplasmic Ca 2+ level in nucleus accumbens neurons, an effect that is blocked by Sigma-1R antagonists. OXA (17-33) serves as an important biological probe for investigating the function of the OX1 receptor. OXA (17-33) can be modified via incorporation of mixed disulfide bonds of homocysteine and cysteamine, and is widely used in studies related to insomnia and narcolepsy .

EP39 is a potent HIV-1 maturation inhibitor. EP39 interacts with the SP1 domain of Gag. EP39 decreases the dynamics of CA-SP1 junction, by binding to the QVT motif of the SP1 domain, and perturbs the natural coil-helix equilibrium on both sides of the SP1 domain by stabilizing the transient alpha helical structure. EP39 acts by arresting maturation of HIV-1 thereby blocking its infectivity .
