A microbial ethyl esther sophorolipid derivative with no acetylated groups produced by Candida species, for treating and preventing sepsis/septic shock. The method of producing sophorolipids is through microbial resting cells of Candida bombicola. The sophorolipids obtained from resting state cultures are isolated as a complex mixture of compounds and then decanted as a dense oil from the culture broth, subsequently washed to remove free fatty acids. Secondary chemical transformation via base catalyzed hydrolysis is used to reduce the 8 possible structural sophorolipid species to a single moiety, the 17-L-[(2′-O-b-D-glucopyranosyl-b-D-glucopyranosyl)-oxy]-cis-9-octadecenoate de-acetylated free acid. The compound acts primarily through decreasing inflammatory cytokines and eliciting other synergistic anti-inflammatory mechanisms by blocking TLR4-CD14 upstream of the inflammatory signaling cascade. The compound can be administered either intraperitoneally or intravenously at single or multiple doses of 5-30 mg/kg of weight in solvent media or in capped nanoparticles, preferably within 48 hours of sepsis inception.
