To introduce and evaluate AMBER, a flexible computational program designed to construct molecular models and calculate inter- and intramolecular interactions using empirical energy methods.
Implemented empirical energy calculation algorithms capable of modeling small chemical compounds as well as large polymers.
Simulated rotational isomerism across D-Val, L-Pro, and L-Pro-Sar amide bonds in actinomycin D.
Evaluated energy profiles and structural conformations comparing the theoretical Sobell model with actinomycin D X-ray crystallographic structures.
Demonstrated a generalizable molecular modeling framework capable of energy refinement across diverse molecular scales.
Characterized conformational energy barriers and rotational isomers for specific amide bonds within actinomycin D.
Resolved structural and energetic differences between proposed theoretical models and empirical X-ray diffraction data.
