I have three compounds named as SMAL102, SMAL104 and SMAL104, the CMC value is 0.006, 0.040 and 0.2 mg/ml respectively. We analyzed the cytotoxicity in colon cancer and found SMAL102 showed promising anticancer activity. while SMAL104 anad SMAL108 failed to show the anticancer activity. the concentration which I used for cytotoxicity assay is that 2.5, 5 and 10 ug/ml, which is lower than SMA102 CMC value, while SMAL104 and 108 have higher CMC value.
How can I interpret the results?
