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 .

HA2 peptide is a potent pH-responsive fusion peptide derived from hemagglutinin (HA), corresponding to the N-terminal fusion peptide domain consisting of 23 amino acid residues of HIV-1 gp41 envelope glycoprotein. HA2 peptide adopts a random coil structure under physiological pH conditions; in acidic endosomes, protonation of carboxyl groups reduces negative charge, inducing a transition to an α-helical conformation that can fuse with and destabilize the endosomal membrane. After binding to membranes, the N-terminal and middle regions of HA2 peptide mainly adopt a β-strand conformation, while the C-terminal region remains unstructured. HA2 peptide induces lipid mixing and promotes aqueous content leakage from large unilamellar vesicles whose lipid composition matches that of HIV-1 viruses and target T cells. HA2 peptide is anionic and can bind to cationic peptides to achieve siRNA condensation. HA2 peptide can be used in studies related to cancer and human immunodeficiency virus (HIV) infection .

Riboswit-modulator-1 (Compound A1), a covalent RNA ligand, is a bacterial Flavin mononucleotide (FMN) riboswitch modulator. Riboswit-modulator-1 modifies unpaired guanine residues (G11 and G62) proximal to the FMN-binding site through a proximity-driven mechanism, and interferes with its conformational transitions. Riboswit-modulator-1 acts as a negative antagonist by eliciting the opposite effect of the natural effector molecule .

CP-69799 is an azahomostatine-containing oligopeptide transition-state analogue inhibitor with a hog renin IC50 of 6e-9 M, human plasma renin IC50 of 3e-7 M and Ki of 0.310 μM, and endothiapepsin Ki of 0.27 μM. CP-69799 binds endothiapepsin’s active site cleft in extended conformation, fills S4 to S3' pockets, displaces native solvent molecules, induces domain rotation, and reduces thermal mobility of endothiapepsin’s flap and helix regions. CP-69799 acts as a transition-state analogue inhibitor of hog renin and human plasma renin. CP-69799 contains a polar lysine residue at the P2' position, with a nitrogen atom replacing the P1' Cα atom of the hydroxyethylene dipeptide isostere. CP-69799 can be used for the research of hypertension .

P53 Activator 16 (Compound JC16) is a p53 activator. P53 Activator 16 exhibits selective cytotoxicity and pro-apoptotic (apoptosis) activity towards p53-Y220C mutant cancer cells, while having little effect on wild-type or P53-deficient cells. P53 Activator 16 induces the conformational transition of cell p53-Y220C from the mutant form to the wild-type form, accompanied by the transcriptional activation of p53 target genes, without increasing the overall level of p53 protein. P53 Activator 16 can be used for the study of p53 mutant cancers .

UE01 is an orally active, selective small-molecule modulator targeting both ULK1/ERK1/2. UE01 activates hULK1 with an EC50 of 695.30 nM and a KD of 114.3 nM for ULK1; it inhibits hERK1 with an IC50 of 179.90 nM and a KD of 114 nM for ERK1; it shows weak binding to ERK2 with a KD of 2.8 mM. UE01 induces the conformational transition of ULK1 from an inactive to an active state, enhances the phosphorylation of ULK1 Ser317 and mAtg13 Ser355, and reduces the phosphorylation of ULK1 Ser757. UE01 competitively occupies the ATP-binding pocket of ERK1, inhibits ERK1 kinase activity, and reduces the activity of the ERK1/2 signaling pathway. UE01 induces complete autophagy flux and apoptosis, upregulates Atg5, Atg7, LC3-II/LC3-I, Bax, cytochrome C (Cyt c), Cleaved-Caspase 3, Cleaved-PARP1 and E-cadherin, downregulates p62, Bcl-2, MMP-2 and MMP-9, reduces the phosphorylation of Exo70 Ser250, and promotes the proteasome-dependent degradation of Cav-1, thereby inhibiting EMT-related phenotypes and extracellular matrix degradation. UE01 can be used in studies related to triple-negative breast cancer .
