Allgemeine Beschreibung

3,3′-Dipropylthiacarbocyanine iodide is a carbocyanine fluorescent dye sensitive to membrane potential. This cyanine dye plays a vital role as an optical probe of membrane potential. An increase in the fluorescence intensity of the dye indicates depolarization of the plasma membrane potential.

Anwendung

3,3′-Dipropylthiacarbocyanine iodide has been used to determine bacterial membrane permeability by the effect of electrochemical scaffold treatment.

Biochem./physiol. Wirkung

The embrane potential sensitive dye, 3,3′dipropylthiacarbocyanine iodide enters only depolarized cells, where it binds reversibly to lipid-rich intracellular components.

The ever-growing concerns on multi-drug resistant (MDR) bacteria lead to urgent demands for novel antibiotics including antimicrobial peptides (AMPs). Pt5, a peptide consisting of the C-terminal 55 residues of zebrafish phosvitin, has been shown to function as an antibacterial agent.

Conventional role of ribosomal proteins is ribosome assembly and protein translation, but some ribosomal proteins also show antimicrobial peptide (AMP) activity, though their mode of action remains ill-defined. Here we demonstrated for the first time that amphioxus RPS15, BjRPS15, was

We compared the potency of four derivatives of the antimicrobial peptide halictine-2 against six Candida species. Observed activity was peptide and species specific. Halictines rapidly permeabilized cell membranes and caused the leakage of cytosolic components. Their killing potential was enhanced
