UP360,a Standardized Composition from Extracts of Aloe barbadense,Poria cocos,and Rosemary officinalis Protected Against Sepsis and Mitigated Acute Lung Injury in Murine Models

Abstract

Sepsis is a life-threatening organ dysfunction caused by a dysregulated and unbalanced immune response to microbial infection. Restoring immune homeostasis and infection control are considered the primary strategies to manage sepsis. Natural bioactives such as polysaccharide and polyphenols from botanicals are known for their immune modulation activity. In this study, we evaluated a standardized aloe-based composition, UP360 (constitute of polysaccharides from Aloe barbadense and Poria cocos and polyphenols from Rosemary officinalis) in lipopolysaccharide (LPS)-induced sepsis and acute inflammatory lung injury murine models. Prophylactic oral administration of UP360 for 7 days at an oral dose of 500 mg/kg improved the survival rate of mice by 62.5%, whereas all mice in the vehicle control group were deceased 82 h after LPS injection. The merit of combining these traditional herbs to yield the standardized composition UP360 was also demonstrated in this model with a mortality rate of only 30.8%, whereas 76.9%, 53.9%, and 61.5% were recorded for each individual constituents A. barbadense, P. cocos, and R. officinalis, respectively. Dose-correlated statistically significant reductions in proinflammatory cytokines and chemokine tumor necrosis factor alpha (TNF-α), interleukin (IL)-1β, IL-6, and cytokine-induced neutrophil chemoattractant (CINC)-3 were observed for UP360 when administered at 250 and 500 mg/kg orally for 7 days before induction of acute lung injury (ALI) model in rats. The histopathology data from lung showed statistically significant 37.9% and 37% reductions in the overall lung damage severity and pulmonary edema, respectively, for UP360-treated rats. The aloe-based composition UP360 effectively improved the survival rate of septic animals and mitigated the severity of LPS-induced ALI in vivo. These data warrant further investigation of the composition for a potential application in human as an adjunct supplement in respiratory distress and sepsis.
