Inhibiting CK2 among Promising Therapeutic Strategies for Gliomas and Several Other Neoplasms

Pharmaceutics, 2022
In gliomas, casein kinase 2 (CK2) plays a dominant role in cell survival and tumour invasiveness and is upregulated in many brain tumours. Among CK2 inhibitors, benzimidazole and isothiourea derivatives hold a dominant position.
