Cytochalasin A is a cell-permeable fungal toxin and is an oxidized derivative of cytochalasin B. Cytochalasin A is an inhibitor of HIV-1 protease (IC50 = 3 μM), inhibits actin polymerization and interferes with microtubule assembly by reacting with sulfhy
Helenalin is a selective inhibitor of transcription factor NF-κB by direct targeting of p65. It is an anti-inflammatory sesquiterpene lactone compound with alkylating activity. Through its ability to target the cysteine sulfhydryl groups in the p65 subunit of NF-κB, helenalin effectively inhibits its DNA binding.
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].
MTSEA hydrobromide is a sulfhydryl-reactive compound that modifies free cysteine residues to produce a positively charged side chain similar in size to lysine.
Sulfo-SMPB sodium is a non-cleavable heterobifunctional chemical cross-linking reagent that combines N-hydroxysuccinimide ester and maleimide groups. This compound enables the covalent conjugation of molecules possessing amine and sulfhydryl functionalities.
SBA crosslinker is a sulfhydryl and amino reactive heterobifunctional protein crosslinking reagent. SBA protein crosslinker is non-cleavable and is among the shortest amine and sulfhydryl reactive crosslinking reagents known with a spacer arm length of on
SMPB crosslinker is a heterobifunctional protein crosslinking reagent that is reactive toward sulfhydryl and amino groups. The SMPB protein crosslinker is an extended chain length analog of MBS crosslinker. SMPB crosslinker's spacer arm is non-cleavable.
