PTK6 and neoplasm: Consequently, many studies have focused on inhibiting PTK6 expression in order to slow tumor progression.The novel compounds(E)-5-(benzylideneamino)-1 h-Benzo [d]imidazol-2(3H), semi-synthetically optimized sipholenol A ester, and 4-aniline-substituted α-carboline have all been confirmed to prevent tumor development by inhibiting the expression of PTK6 [17–19].
