Revisiting the antiangiogenic mechanisms of fluorinated thalidomide derivatives.

ABSTRACT: Introduction of fluorine into bioactive molecules has attracted much attention in drug development. For example, tetrafluorination of the phthalimide moiety of immunomodulatory drugs (IMiDs) has a strong beneficial effect on the ability to inhibit angiogenesis. The neomorphic activity of E3 ligase complexes is induced by the binding of IMiDs to cereblon. We investigated that a set of eight thalidomide analogs, comprising non- and tetrafluorinated counterparts, did not induce the degradation of neomorphic substrates (IKZF3, GSPT1, CK1α, SALL4). Hence, the antiangiogenic activity of fluorinated IMiDs was not triggered by neosubstrate degradation features. A fluorine scanning of non-traditional IMiDs of the benzamido glutarimide chemotype was performed. By measuring the endothelial cell tube
