Abstract: Azaserine is an analogue of glutamine and a drug used for treatment of pancreatic cancer. Our goal was to understand the antagonistic role of azaserine and the underlying mechanism of drug interactions against certain target molecules viz, membrane bound protein -Gamma glutamyl transferase, rate limiting enzyme-Glutamine fructose amido transferase, and muscarinic acetylcholine enzyme (M3) receptors. Protein-Ligand interaction has a significant role in structure-based drug studies. ADMET screened compound showed good solubility, absorption at (3 level). The internalization of the drug is moderate in intestine and cannot enter blood brain barrier. The rate of degradation and elimination of the drug is notable faster. Also, screened compound is free from noxious effect of hepatotoxicity, followed by no evidence of interacting with liver enzymes. Finally, the compound after docking showed interactions with the target proteins and binding energy levels were significant indicating the inhibitory role of azaserine. Our studies therefore reveal the mechanism of interaction at molecular levels and strong binding ability of drug to target molecules to inhibit their activity. Role of azaserine as a M3 antagonist is a model to understand mechanisms to prevent cancer cell growth and metastasis, which needs further investigation.
