In this work, the multifunctional potential of four 3-acetylcoumarin derivatives was studied. The derivatives were significantly active against bacteria Staphylococcus aureus, Pseudomonas aeoginosa and fungal strain Candida albicans. The results of antioxidant activity assays were promising when compared to ascorbic acid. The in vitro anticancer activity was carried out using MTT assay on human cancer cell line COLO-205 and 3ACDT showed commendable antiproliferative activity along with appreciable tumor selectivity with distinct selectivity index. Moreover, ADMET properties of the compounds were determined using the pKCSM and SwissADME online tools and all compounds were found with good pharmacokinetic profile. Hence, from the obtained results from all the 3-acetylcoumarin derivatives, 3ACDT exhibited good therapeutical potential and can be optimized for lead development.

Under solvent free conditions and in presence of a base 3-(2-(subsituted-(trifluoromethyl)phenylamino)acetyl)-2H-chromen-2-one derivatives were synthesized by grinding technique. Structural investigations were carried out with IR studies, HRMS, ¹HNMR and ¹³CNMR. The compounds were checked for their in vitro anticancer activities against three different human cancer cell lines viz human breast cancer cell line (MCF-7), human cervical cancer cell line (HeLa) and human oral squamous cell carcinoma (SCC-40) using SRB method. All the title compounds showed low toxicity towards non-malignant PBMC cells indicating their tumour selectivity. The compounds exhibited good in vitro anti-proliferative potency at lower concentrations against HeLa and MCF-7 cell lines and remain moderately active against SCC-40.
