International audience; Small Conductance Calcium (Ca 2-)-activated potassium (K-) channels (SKCa) are now proved to be involved in many cancer cell behaviors such as proliferation or migration. The SIG channel isoform was particularly described in breast cancer where it can be associated with the Orai 1 Ca 2-channel to form a complex that regulates the ca 2-homeostasis during tumor development and acts as a potent mediator of bone metastases development in vivo. Until now, very few specific blockers of Orail and/or SIG have been developed as potential anti-metastatic compounds. ln this study, we illustrated the synthesis of new families of lipophilic pyridine and tetrahydropyridine derivatives designed as potential modulators of SK3 channel. The toxicity of the newly synthesized compounds and their migration effects were evaluated on the breast cancer cell line MDA-MB-435s. Two molecules (7a and toc) demonstrated a significant decrease in the SK3 channel-dependent migration as well as the SK3/Orai1-related Ca 2-entry. Current measurements showed that these compounds are more likely SK3-selective. Taken all together these results suggest that such molecules could be considered as promising anti-metastatic drugs in breast cancer.
