Non-specific tissue and necrotic protein substrates; broad microbial flora

This target represents a heterogeneous collection of biological materials and microorganisms rather than a single defined molecular entity. It encompasses necrotic (devitalized) tissue, proteinaceous debris such as slough and eschar, and a diverse range of microbial flora including bacteria, fungi, and viruses [1, 2]. This category is primarily associated with the action of topical antiseptics, disinfectants, and enzymatic debriding agents used in wound management and infection control [1, 3]. Antiseptics like povidone-iodine and hydrogen peroxide exert their effects through non-specific mechanisms such as oxidation and protein denaturation, which disrupt the structural integrity and metabolic processes of a wide variety of microbes [3, 4]. Debriding agents, including enzymes like collagenase, specifically target and hydrolyze necrotic protein substrates to facilitate the removal of non-viable tissue from wound beds, thereby promoting the inflammatory and proliferative phases of healing [2]. Because these targets are non-specific, the primary therapeutic challenge involves achieving high efficacy against pathogens and debris while minimizing collateral damage to healthy, regenerating host tissues [1, 2].
