Abstract:
Novel indole-containing analogs were synthesized via a one-pot, multi-component Passerini reaction and subsequently evaluated for their anticancer activity against HeLa, MCF-7, and A549 cancer cell lines using the MTT assay. Among the synthesized compounds, (2-(cyclohexylamino)-1-(3-fluorophenyl)-2-oxoethyl 2-(1H-indol-3-yl)acetate (4f), which demonstrated the most potent cytotoxic activity, exhibited promising results with IC50 values of 17.71 and 19.92 μM against HeLa and MCF-7 cells, respectively. Flow cytometry analysis confirmed that compound 4f significantly induced apoptosis in HeLa cells in a concentration-dependent manner. Furthermore, molecular docking studies into the active site of the anti-apoptotic protein Bcl-xL indicated that compound 4f binds with good affinity, which is consistent with its considerable efficacy in the in vitro tests.

Drug-Receptor Interactions
Several parameters, such as the drug's affinity for its receptor and its efficacy, which is its ability to activate the receptor, determine the drug's effect on the tissue.
Drug-Receptor Interaction: Agonist
Agonists can bind to receptors in different ways. Some agonists bind directly to the receptor's active site, mimicking the endogenous ligand's action.
Adrenergic Agonists: Chemistry and Structure-Activity Relationship
Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
