The malignant transformation of melanocytes causes several thousand deaths each year, making melanoma an important public health concern. Melanoma is the most aggressive skin cancer, which incidence has regularly increased over the past decades. We described here the preparation of new compounds based on the 1-(3,4-dihydroxyphenyl)imidazo[1,2-a]quinoxaline structure. Different positions of the quinoxaline moiety were screened to introduce novel substituents in order to study their influence on the biological activity. Several alkylamino or alkyloxy groups were also considered to replace the methylamine of our first generation of Imiqualines. Imidazo[1,2-a]pyrazine derivatives were also designed as potential minimal structure. The investigation on A375 melanoma cells displayed interesting in vitro low nanomolar cytotoxic activity. Among them, 9d (EAPB02303) is particularly remarkable since it is 20 times more potent than vemurafenib, the reference clinical therapy used on BRAF mutant melanoma. Contrary to the first generation, EAPB02303 does not inhibit tubulin polymerization, as confirmed by an in vitro assay and a molecular modelisation study. The mechanism of action for EAPB02303 highlighted by a transcriptomic analysis is clearly different from a panel of 12 well-known anticancer drugs. In vivo EAPB02303 treatment reduced tumor size and weight of the A375 human melanoma xenografts in a dose-dependent manner, correlated with a low mitotic index but not with necrosis.

The transcription nuclear factor NF-κB plays a pivotal role in chronic and acute inflammatory diseases. Among the several and diverse strategies for inhibiting NF-κB, one of the most effective approach considered by the pharmaceutical industry seems to be

The present invention provides methods for inhibiting protein kinases selected from the group consisting of AKT, Checkpoint kinase, Aurora kinase, Pim-1 kinase, and tyrosine kinase using imidazo[1,2-a]pyrazine compounds and methods of treatment, prevention, inhibition, or amelioration of one or more diseases associated with protein kinases using such compounds.
