WebJun 5, 2015 · Antiproliferative activity was expressed as the 50% effective concentration (EC 50), where a low EC 50 value means a high antiproliferative value. Based on the EC 50 values in Figure 3 B, the antiproliferation effects of the PPP on the seven cell lines were in the following decreasing order: MCF-7 > A375 > A549 > SH-SY5Y > HeLa > HT29 > LOVO. WebThe EC50 of a graded dose response curve therefore represents the concentration of a compound where 50% of its maximal effect is observed. after a specified exposure duration. For clarification, a graded dose response curve shows the graded effect of the drug over the dose of the drug in one or an average of subjects.
WebThis allows the calculation of the selectivity index (SI), which is defined as the ratio of the 50% cytotoxic concentration (CC 50) to the inhibitory concentration of 50% (IC 50). Selectivity index: SI = CC 50 /IC 50. It is desirable to have a high therapeutic index giving maximum antiviral activity with minimal cell toxicity.
