ABSTRACT: Small molecules are composed of chemical functional groups; they are sets of connected atoms or atom groups that determine properties and reactivity of the parent molecule. DrugBank is a rich source of information that containing molecular data about small molecules, their mechanisms, pharmaceutical interaction and targets. In this study, After collecting data of small drug molecules from DrugBank database and classifying them in different categories based on their mechanism of action, the therapeutic properties of the molecules were recorded. Finally, the functional group from the pharmaceutical structures were elucidated and registered for each group. The functional groups were divided into five distinct groups in drug design, and a correlation between identified functional group to pharmaceutical structure were indicated according to the classified functional groups of small molecule and drug categories; then defined their frequency in categories, at high abundant functional group present in categories reported. The most frequent rings were benzene and cyclohexane; the common acid functionality had been acetate (carboxy-); three most repeated saturated heterocyles are piperidine, piperazine and azetidine; among the unsaturated heterocyles, pyridine, imidazole and indole are noticed; This database, that may be guidance for researchers with the aim at designing new drugs.
