    <p>EC venom (5 µg) was pre-incubated separately with varied doses of compound 5d (1∶0; 1∶5; 1∶10 and 1∶25; venom: compound; w/w) for 10 min at 37°C. The samples were injected intramuscularly into group of mice (n = 5) in a total volume of 50 µL saline. Mice were anaesthetized and sacrificed after 3 h and the assay was performed as described in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0106364#s2" target="_blank">materials and methods</a> section. <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0106364#s3" target="_blank">Results</a> are expressed as mean ± SEM of three independent experiments. <b>***</b><i>p</i><0.001, <b>**</b><i>p</i><0.01, a - significant compared to saline control group and b - significant compared to venom alone group.</p

    <p>EC venom (0.2 µg) was pre-incubated separately with different doses of compound 5d (1∶0; 1∶1; 1∶5; 1∶10; 1∶25 and 1∶50; venom: compound; w/w; Lane 2–7 respectively, Lane-1 represents substrate alone and Lane-8 represents substrate with 10 µg of compound 5d alone) for 10 min at 37°C. The reaction was initiated by adding respective substrates (A) fibrin and (B) fibrinogen and incubated for 30 min. Samples were electrophoresed on 10% SDS-PAGE and the gels were processed as described in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0106364#s2" target="_blank">materials and methods</a> section.</p
