Abstract:
Based on our earlier QSAR study, a series of 1, 5-N,N'-substituted-2-(substituted naphthalenesulphonyl) glutamamides were synthesized as possible anticancer agents. Anticancer activities of these synthesized compounds were evaluated in vivo on Swiss Albino mice against Ehrlich Ascites Carcinoma (EAC) cells where inhibitions of tumor cell and tumor weight were considered as biological activity parameters. A comparative QSAR study was done with a set of descriptors and logarithm of tumor cell inhibition. The result shows the importance of topological parameters like ETSA and RTSA indices as well as electronic parameter like Wang-Ford charges of different atoms. Electrophilic attack at atom number 5 and increased number of chlorine atom may be favorable whereas presence of methoxy group at the atom number 8 in naphthalene ring may be detrimental to the activity.

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.
