1,6-bis[N′-(p-Chlorophenyl)-N5-biguanido]hexane, 2HCl CHX White solid. HYGROSCOPIC. PACKAGED UNDER INERT GAS. An anti-microbial agent that acts as an inhibitor of MMP-2 and MMP-9; however, MMP-2 is more sensitive to chlorhexidine than MMP-9. Inhibits the collagenase activity of MMP-8 released by PMA-triggered polymorphonuclear leukocytes (PMNs) in a dose-dependent manner. CHX may possibly act through a cation-chelating mechanism. Purity: ≥95% by titration. RTECS XA5285000, CAS 3697-42-5. Note: presence of CaCl2 in the medium blocks the inhibitory activity of CHX. Merck Index: 14, 2091 Ref.: Gendron, R., et al. 1999. Clin.
