 Therapeutic leads generated using PDN were directly tested for survival benefit using a murine model of endotoxemia. Select compounds were injected 24 hours before and on the day of LPS administration, using routes and doses specified in the methods. C57bl/6 female mice were injected with a high-lethality dose of E. coli LPS (38-40 μg/g) followed by a subcutaneous injection of sterile saline. Significant differences in concentration between drug and vehicle-treated pre- and post-pubertal mice are labeled with **** (p<0.0001), *** (p<0.001, ** (p<0.01), or * (p<0.05). Percent survival was compared using a log rank Mantel Cox test
