  Inhibitors of the RET tyrosine kinase based on a 2-(alkylsulfanyl)-4-(3-thienyl)nicotinonitrile scaffold

  摘要：

  In an approach to optimize 2-(4-fluorobenzylsulfanyl)-4-(2-thienyl)-5,6,7,8-tetrahydroquinoline-3-carbonitrile (1a), a weak inhibitor of the cancer-related tyrosine kinase RET originating from a screening campaign, analogues with 3-thienyl substitution were prepared. Among the novel derivatives, 2-amino-6-{[2-(4-chlorophenyl)-2-oxoethyl]sulfanyl}-4-(3-thienyl)pyridine-3,5-dicarbonitrile (13g) was identified as a submicromolar RET inhibitor, displaying 3- and 100-fold selectivity versus ALK and ABL kinases, respectively. The novel inhibitor exhibited antiproliferative activity in the micromolar concentration range against both RET-dependent and RET-independent cancer cell lines. Docking experiments suggest a binding mode of the new inhibitors in the ATP binding pocket of the target kinase, explaining the observed structure activity relationships.

Along with the pharmacological evaluation, chemical stability of methyl 3-(((6-amino-3,5-dicyano-4-(furan-2-yl)pyridin-2-yl)sulfanyl)methyl)benzoate 10 was assessed in plasma matrices (rat and human), and molecular modeling studies were carried out to better rationalize the available structure-activity

  A new set of amino-3,5-dicyanopyridines was synthesized and biologically evaluated at the adenosine receptors (ARs). This chemical class is particularly versatile, as small structural modifications can influence not only affinity and selectivity, but also the pharmacological profile. Thus, in order to deepen the structure–activity relationships (SARs) of this series, different substituents were evaluated
