Alamethicin is a linear 20-amino acid antibiotic, which can induce voltage-gated conductance in model and cell membranes. Alamethicin exhibits antimicrobial activity against Gram-positive bacteria, but not Gram-negative bacteria. Alamethicin can form an amphipathic α-helical structure in biological membranes .

Semustine is an orally active, blood-brain barrier permeable antitumor alkylating agent with a binding affinity of 1.53 × 10 3 M -1 for guanine and thymine residues in bovine DNA. Semustine undergoes major groove-directed alkylation at guanine residues to form O6-chloroethylguanine and N1-O6-ethanoguanine adducts, and generates dG-dC interstrand crosslinks. Semustine induces partial B- to C-type transition of DNA, base stacking and helical structure distortion, mild dehydration, as well as partial DNA double-strand unwinding. Semustine can be used in research related to Lewis lung cancer, leukemia, Hodgkin's lymphoma, malignant melanoma, glioma, and diffuse large B-cell lymphoma .

MreB Perturbing Compound A22 hydrochloride (A22 hydrochloride) is a reversible MreB inhibitor and antimicrobial agent that exhibits bacteriostatic activity against Escherichia coli, with low activity against Gram-positive bacteria. MreB Perturbing Compound A22 hydrochloride rapidly and reversally delocalizes MreB from the helical/circular structures in cells, impairs MreB function, and reduces the binding of MreB to the chromosomal region proximal to the replication origin. MreB Perturbing Compound A22 hydrochloride alters the cell morphology of caulobacters to round/lemon-shaped, slows caulobacter growth, blocks their cell division, and induces the formation of spherical morphology, asymmetric division, and anucleate cells in Escherichia coli. MreB Perturbing Compound A22 hydrochloride is used for studies related to bacterial rod-shaped morphology determination, chromosome segregation, and cell division mechanisms .

ALFA-tag is a small and stable α-helical structure composed of 15 amino acids. ALFA-tag is highly hydrophilic and can be placed at the N-terminus, C-terminus, or between two independently folded domains of the target protein without affecting the function of the protein. ALFA-tag is widely used as an epitope tag and is used for the detection and manipulation of proteins in living cells .

TP4 (Nile tilapia piscidin) is an orally active amphipathic α-helical cationic antimicrobial peptide. TP4 (Nile tilapia piscidin) exerts broad-spectrum bactericidal activity against Gram-positive and Gram-negative bacteria by disrupting cell membrane structures, and also exhibits certain hemolytic activity. TP4 (Nile tilapia piscidin) regulates the innate immune system and enhances the expression of lysozymes, cytokines and antioxidant enzymes to resist bacterial infection. TP4 (Nile tilapia piscidin) also stimulates the proliferation of keratinocytes and fibroblasts, and significantly promotes the healing of wounds infected with MRSA. TP4 (Nile tilapia piscidin) can be used in research related to bacterial infection, peritonitis, wound healing and other fields .

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.

HIV HIV Protease

Infection

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 .

S-312 is a calcium antagonist with a bicyclic dihydrothienopyridine structure. S-312 can relax the helical strips of various isolated rabbit arteries procontracted with high potassium depolarizaiton. S-312 competitively imhibits calcium-induced contractions in depolarized basilar and femoral arteries. S-312 increases AV nodal conduction time in Langenedorff-perfused isolated rabbit hearts. S-312 exhibits vasculoselectivity, particularly for cerebral vessel .
