ANLIZE: a molecular mechanics force field visualization tool and its application to 18-crown-6.

abstract：:Drug discovery is an expensive and time-consuming process. To make this process more efficient quantum chemistry methods can be employed. The electrophilicity index is one property that can be calculated by quantum chemistry methods, and if calculated correctly gives insight into the reactivity of covalent inhibitors....
