The biological activity, in later stages a selectivity index or some other biological property, serve as the "fitness function" for the "survival" of certain structural entities. However, several surprising structure-activity relationships demonstrate how difficult rational drug design can be and to which extent structure-based and computer-aided approaches can support this process. 5,12-21

Sex differences in humans have been studied in a variety of fields. In humans, biological sex consists of five factors present at birth: the presence or absence of the SRY gene (an intronless sex-determining gene on the Y chromosome), the type of gonads, the sex hormones, the internal reproductive anatomy (such as the uterus), and the external genitalia.

Polo-like kinase 1 (PLK1) plays key roles in the regulation of mitotic progression, including mitotic entry, spindle formation, chromosome segregation, and cytokinesis. PLK1 expression and activity are strongly linked to proliferating cells. Many studies have shown that PLK1 expression is elevated in a variety of tumors, and high expression often correlates with poor prognosis.
