BACE-IN-1 acetate (BACE-IN-1 acetate (350228-37-4，Free base)) has been used as β-site amyloid precursor protein (APP) cleaving enzyme-1 (BACE1) inhibitor in BACE1 inhibitor assay. β-Site amyloid precursor protein (APP) cleaving enzyme-1 (BACE1), an aspartic protease belongs to the protease family of enzymes comprises of six luminal cysteine residues. These residues help in the formation of three intermolecular disulfide bonds and N-linked glycosylation sites.

L-Glutathione reduced (Glutathione) is a naturally occurring tripeptide found in cells as an endogenous antioxidant that scavenges oxygen free radicals. L-Glutathione reduced is a cofactor for certain enzymes and is involved in the rearrangement of protein disulfide bonds and the reduction of peroxides.

(±)-trans-1,2-Bis(2-mercaptoacetamido)cyclohexane (BMC) is a cyclohexane with two mercaptoacetamido groups. It is used, both in vitro and in vivo, to promote the correct folding of proteins that require disulfide bonds for functionality. For in vitro applications, BMC may be used to facilitate protein refolding of solubilized proteins from inclusion bodies. Reducing agents, like dithiothreitol, may interfere with refolding. BMC may also be added to the growth medium of cells, including yeast cells, to enhance the folding of proteins with disulfide bonds in vivo.

Calciseptine, a neurotoxin isolated from the Black Mamba (Dendroaspis p. polylepis) venom, comprises 60 amino acids and is stabilized by four disulfide bonds. It specifically targets and blocks L-type calcium channels [1].

DST crosslinker(disuccinimide tartarate) is an isotype bifunctional, cleavable crosslinker (cleavable by an oxidizer) for applications that require crosslinking cleavability and that do not interfere with protein disulfide bonds with reducing agents.

DM4-SPDP, a drug-linker conjugate, integrates the antitubulin agent DM4 with the linker SMCC, facilitating the creation of antibody drug conjugates[1]. Additionally, SPDP serves as a short-chain crosslinker enabling amine-to-sulfhydryl conjugation, leveraging NHS-ester and pyridyldithiol groups to establish cleavable (reducible) disulfide bonds with cysteine sulfhydryls[2][3].

Epsilon-V1-2, a Cys-conjugated, is a biologically active peptide known as the εPKC-specific inhibitor. It hampers εPKC functionality by obstructing its translocation and the phosphorylation of MARCKS, additionally perturbing εPKC's interaction with its anchoring protein, εRACK. The peptide includes a cysteine residue at its C-terminus, facilitating the formation of potential disulfide bonds with carrier proteins. Pyroglutamyl formation can occur spontaneously at the N-terminus if glutamine or glutamic acid is present, enhancing peptide stability against gastrointestinal proteases. Pyroglutamyl peptides, a recognized subset, are accounted for in the peptide's purity during HPLC analysis.

GsAF-1, a peptide toxin with three disulfide bonds, is derived from the venom of the Chilean pink tarantula and has potential applications in the research of moderate-to-severe pain [1].
