New targeted therapy approaches for certain subtypes of breast cancer, such as triple-negative breast cancers and other aggressive phenotypes, are desired. High levels of the mitotic checkpoint kinase Mps1/TTK have correlated with high histologic grade in breast cancer, suggesting a potential new therapeutic target for aggressive breast cancers (BC). Novel small molecules targeting Mps1 were designed by computer assisted docking analyses, and several candidate compounds were synthesized. These compounds were evaluated in anti-proliferative assays of a panel of 15 breast cancer cell lines and further examined for their ability to inhibit a variety of Mps1-dependent biological functions. The results indicate that the lead compounds have strong anti-proliferative potential through Mps1/TTK inhibition in both basal and luminal BC cell lines, exhibiting IC50values ranging from 0.05 to 1.0?μM. In addition, the lead compounds 1 and 13 inhibit Mps1 kinase enzymatic activity with IC50values from 0.356?μM to 0.809?μM, and inhibited Mps1-associated cellular functions such as centrosome duplication and the spindle checkpoint in triple negative breast cancer cells. The most promising analog, compound 13, significantly decreased tumor growth in nude mice containing Cal-51 triple negative breast cancer cell xenografts. Using drug discovery technologies, computational modeling, medicinal chemistry, cell culture and in vivo assays, novel small molecule Mps1/TTK inhibitors have been identified as potential targeted therapies for breast cancers.
2,6-DICHLORO-8-IODO-7-DEAZAPURINE FOR SYNTHESIZING POLYSUBSTITUTED 7-DEAZAPURINE DERIVATIVE
-
, (2017/01/31)
PROBLEM TO BE SOLVED: To overcome many times and labors needed for synthesizing various polysubstituted 7-deazapurine derivatives which is expected usefulness or the like as pharmaceutical because they are conventionally synthesized through several synthetic routes depending on kinds and positions of substituents. SOLUTION: Used is 2,6-dichloro-8-iodo-7-deazapurine represented by the following formula (1) available as a key intermediate of polysubstituted 7-deazapurine derivatives. Predetermined substituents can be introduced to 8-, m6- and 2-positions respectively in this order, therefor it is useful as an intermediate for synthesizing targeted polysubstituted 7-deazapurine derivative.

The palladium-catalyzed Suzuki-Miyaura reaction of 2,4-dichloropyrrolo[2,3-d]pyrimidine with aryl boronic acids has been studied. Pd(OAc)2/dicyclohexyl(2-biphenyl)phosphine/K3PO4 was found to be an efficient catalyst system to prepare 4-aryl-2-chloro- and 2,4-diarylpyrrolo[2,3-d]pyrimidines. Novel non-linear molecules consisting of a pyrrolo[2,3-d]pyrimidine core and aryl branches have been elucidated as blue light-emitters with fluorescence quantum yields ranging from 4% to 67% in THF solution. The impact of an electron-withdrawing t-BuOCO group attached to the pyrrole ring of pyrrolopyrimidine derivatives on optical properties is discussed.

A series of pyrazolo[3,4-d]pyrimidine, pyrrolo[2,3-d]pyrimidine and 6-arylpurine adenosine A2A antagonists is described. Many examples were highly selective against the human A1 receptor sub-type and were active in an in vivo model of Parkinson's disease.
