Previously it was reported that combining antibiotics with L-97-1, an adenosine A1 receptor antagonist, significantly improves survival and blocks acute lung injury induced by Yersinia pestis CO 99 in a rat model of pneumonic plague. In the current studies using a conscious rat model of cecal ligation and puncture (CLP) sepsis, L-97-1 was administered in daily intravenous infusions in combination with antibiotics to simulate the use of L-97-1 as an anti-sepsis therapeutic in the clinical setting. In these studies, when administered at 12 h following CLP, in combination with broad spectrum antibiotics, ceftriaxone and clindamycin, L-97-1 improves 7 day (d) survival [25%, 35%, and 75% for L-97-1 (10 mg/kg/h, 12.5 mg/kg/h, and 15 mg/kg/h, respectively) versus (vs.) 25% for antibiotics alone] in a dose-dependent manner. The addition of L-97–1, 15 mg/kg/h to antibiotics significantly increased 7 d survival following CLP compared to therapy with either antibiotics alone (P=0.002) or L-97-1 at 15 mg/kg/h alone (P<0.001) and was not significantly different than survival in sham CLP animals (Log-rank (Mantel-Cox) test with Bonferroni׳s correction for multiple comparisons). Moreover, in these studies, in combination with antibiotics L-97-1 dose-dependently protects the kidney, significantly improving renal function at 24 h post CLP at 10 mg/kg/h (P<0.001), 12.5 mg/kg/h (P<0.0001), and 15 mg/kg/h (P<0.0001) vs. antibiotics alone (ANOVA followed by Tukey׳s post-hoc test for pair-wise comparisons). The results of these studies support efficacy for L-97-1 as an anti-sepsis therapeutic.
