screened and A2 and A3 showed their prominence. Interestingly, both A2 and A3 showed more killing potential against multi-drug resistant gram-positive isolates with MIC indices of 16 μg mL−1 and 16 μg mL−1, respectively, against both MRSA and MSSA, while the antitumor agent A3 showed its prominence with GI50 and LC50 41.15 and 133.73 µg mL−1, respectively.
