  novel series of N-aroylated 5-methoxybenzothiophene-2-carboxamides (imides) as potent and selective Clk1/4 inhibitors. Potency of this series was found to be mainly dependent on the presence of an intramolecular H-bond between an ortho-methoxy group and the imide NH, that stabilizes a nearly coplanar conformation of high affinity to the ATP binding pocket(s) of Clk1/4. The two most potent hits in this
