“…For developing high‐quality therapeutic candidates, we combined three heterocyclic units with a coumarin motif. Coumarin has attracted the attention of scientists due to its diverse biological activities in fields such as medicine, pharmacology, cosmetics, and the food industries (Hosseini Nasab, Azimian, et al, 2022; Nasab et al, 2022). Pyrazoline is another well‐known bioactive unit which has been reported to inhibit epidermal growth factor receptor tyrosine kinase (EGFR‐TK) (Lv et al, 2011), aurora kinase (Shin et al, 2013), COX‐2/B‐Raf (Yu et al, 2014), telomerase (Amin et al, 2015), and tubulin assembling (Qin et al, 2015).…”
