An oxidant-generating coupled-enzyme system-based, topical solution comprised of two enzymes, Aspergillus niger-derived glucose oxidase (GO) and porcine myeloperoxidase (p-MPO), as well as glucose, sodium chloride and stabilizing amino acids, with potential broad-spectrum microbicidal activity. Following direct administration of E-101 solution into the surgical incisional wound via microspray, the enzyme GO converts oxygen into hydrogen peroxide (H2O2). In turn, p-MPO catalyzes the reaction of H2O2 with hypochlorous acid (HOCl), which is formed through oxidation of the chloride ion, to generate singlet oxygen (O2*). As p-MPO binds to microorganisms, O2* is able to exert direct oxidative damage to microorganisms, resulting in potent antimicrobial activity. E-101 may act as an anti-bactericidal agent against a variety of microorganisms, including multidrug-resistant strains. This may prevent infection at the surgical site.
