All the mice belonging to control group were challenged with 106P. berghei infected red blood cells (RBCs) intraperitonial (i/p). After challenge mean percent parasitemia, percent activities
of various complexes of artesunate along with animal survivality were monitored. Mean percent parasitemia was calculated for each group on every alternate day up to 30 days by tail blood smear, fixed in methanol and stained in Giemsa stain by counting at least 500 cells Meanpercentparasitemia=infectedRBCs×100/Totalno.ofRBCs Animals were divided into 6 groups and each group comprised of 6 animals (n=6). These were treated orally with single dose therapy (6 mg/kg of artesunate) two times a day on 1 day of post inoculation (PI) for 7 days to monitor the efficacy and potency of prepared lyophilized binary and ternary complexes. Each animal was treated orally with 100 μL artesunate A-1210477 in vitro and its various lyophilized complexes. 1. Control group—treated with 0.5% Idelalisib carboxymethyl cellulose (CMC) suspension; Data of parasitemia of animals treated with different inclusion complexes were statistically assessed by one-way ANOVA and Turkey’s test using Jandel sigma stat 2.0 version. Differences were considered significant at P<0.05. The value of equilibrium constant (K) and enthalpy of binding (ΔHo) were determined by our computer program
utilizing an iterative non-linear least square regression method to minimize the value of ∑(ΔHint(exp)−ΔHint(calc))2 where ΔHint(exp) is the experimentally determined enthalpy of interaction per liter
of solution, ΔHint(calc) is the calculated enthalpy of interaction per liter of solution using iterative method. The equilibrium phase-solubility study diagrams were found Protirelin to be linear characterizing their AL type nature and suggest the formation of first order soluble complexes for artesunate with β-CD, HP-β-CD and Me-β-CD ( Fig. 1). The increment in the solubility of drug seems to depend upon inclusion ability of cyclodextrin molecules with the solubilization strength increasing in the order: β-CD
