RPW-24

RPW-24 (CAS No.: 1001625-82-6) is a small-molecule immunomodulatory agent identified as a stimulator of host innate immune defenses with demonstrated antibacterial activity in model organisms. Functionally characterized in Caenorhabditis elegans, RPW-24 enhances resistance to bacterial infection by activating host immune response pathways rather than acting solely through direct bactericidal effects, supporting its classification as a host-directed anti-infective research tool. Mechanistic studies indicate that RPW-24 modulates conserved innate immune signaling networks in the nematode, providing a useful platform for investigating host–pathogen interactions and immune activation mechanisms. Its activity has been observed in whole-organism infection models, with effective concentrations typically reported in the low micromolar range depending on assay conditions, though precise potency metrics may vary with pathogen strain and experimental design. RPW-24 is widely applicable in studies of innate immunity, antimicrobial discovery, and phenotypic screening workflows, particularly for identifying pathways that enhance host resilience to infection, and is commonly employed in cell-based or organism-level assays where dosing regimens are optimized according to specific experimental objectives.
