  Discovery of thienopyrimidine-based FLT3 inhibitors from the structural modification of known IKKβ inhibitors

  摘要：

  Inactivation of the NF-kappa B signaling pathway by inhibition of IKK beta is a well-known approach to treat inflammatory diseases such as rheumatoid arthritis and cancer. Thienopyrimidine-based analogues were designed through modification of the known IKKb inhibitor, SPC-839, and then biologically evaluated. The resulting analogues had good inhibitory activity against both nitric oxide and TNF-alpha, which are well-known inflammatory responses generated by activated NF-kappa B. However, no inhibitory activity against IKK beta was observed with these compounds. The thienopyrimidine-based analogues were subsequently screened for a target kinase, and FLT3, which is a potential target for acute myeloid leukemia (AML), was identified. Thienopyrimidine-based FLT3 inhibitors showed good inhibition profiles against FLT3 under 1 mu M. Overall, these compounds represent a promising family of inhibitors for future development of a treatment for AML. (C) 2014 Elsevier Ltd. All rights reserved.

  We have developed a simple, efficient and chemoselective approach for the synthesis of m-teraryls by the reaction of 6-aryl-2-oxo-4-(sec.amino)-2H-pyran-3-carbonitriles and 2-(1-arylethylidene)malononitriles under basic conditions. We used 6-aryl-2-oxo-4-methylsulfanyl-2H-pyran-3-carbonitriles as precursors and successfully afforded 5′-methylsulfanyl-[1,1′;3′,1′′]teraryl-4′-carbonitriles. We tried

  These precursors are easily accessible from aryl methyl ketones. Various functional groups like alkyl, aryl, nitrile, amine, aroyl and thiomethyl can be directly installed to the benzene ring. The one-pot approach for the construction of thiomethylated-benzene nucleus was also developed. The structure of the synthesized compound was confirmed by X-ray crystallography.

  The unique reactivity of water in the direct catalytic vinylogous aldol reaction of silyl glyoxylates is reported. With the hydrogen-bonding networks from water, the unfavorable homogeneous reactions in organic solvents were severely suppressed, and the "on water" relay chemistry for the vinylogous aldol reaction was realized in heterogeneous conditions (water as solvent), providing the desired α-hydroxysilanes
