Cell Viability Assay by using the MTT for MDA-MB 231 (A) Graphs represents IC50 (30 μm) for 5-FU on MDA-MB- 231 (B) Graph represents IC50 (15 μg/mL) for CDM on MDA-MB-231 (C) Graphical presentation of estimation of IC50 (10 μg/mL) for CDE on MDA-MB-231 respectively at various concentrations. ***p<0.05 as compared to control and (D) Morphological changes by CDM and CDE on MDA-MB-231 cells at IC50 doses vs control
The chart illustrates the relationship between varying concentrations of Latzeera (in μg/mL) and the percentage of living cells relative to the control. The data highlights a concentration-dependent cytotoxic effect, with cell viability declining progressively from 100% at 0 μg/mL to approximately 23.34% at 1000 μg/mL. This demonstrates that Latzeera exhibits significant cytotoxic activity at higher concentrations, potentially indicating its therapeutic or inhibitory efficacy at elevated doses
