Design and optimization of hybrid of 2,4-diaminopyrimidine and arylthiazole scaffold as anticancer cell proliferation and migration agents
摘要:
Therapeutics of metastatic or triple-negative breast cancer are still challenging in clinical. Herein we demonstrated the design and optimization of a series of hybrid of 2,4-diaminopyrimidine and arylthiazole derivatives for their anti-proliferative properties against two breast cancer cell lines (MCF-7 as human breast cancer and MDA-MB-231 as triple-negative breast cancer). More importantly, some of those compounds with potent antiproliferative activities also indicated excellent inhibitory activities against MDA-MB-231 cell migration. These results suggested that the new series of hybridation of arylthiazoles and aminopyrimidines could be identified and developed as novel highly potential anticancer agents against the triple-negative breast cancer as well as metastatic one in the future.

Dirhodium tetraacetate catalyzed reaction of α-diazo-β-keto-carboxylates and -phosphonates with arenecarboxamides gives 2-aryloxazole-4-carboxylates and 4-phosphonates by carbene N−H insertion and cyclodehydration. In stark contrast, dirhodium tetrakis(heptafluorobutyramide) catalysis results in a dramatic change of regioselectivity to give oxazole-5-carboxylates and 5-phosphonates. α-Diazo-β-ketosulfones

There are disclosed an industrially favorable process for producing a tetrazole compound of general formula (1):
characterized in that a nitrile of general formula (2):
R¹CN (2)
is reacted with hydrazine or a salt thereof in the presence of a catalyst, followed by reaction with a nitrous acid compound of general formula (3):
ANO₂ (3)
or a nitrile of general formula (2) is reacted with hydrogen sulfide, followed by reaction with an alkyl halide of general formula (4):
R⁴J (4)
with hydrazine or a salt thereof, and then with a nitrous acid compound of general formula (3); and an intermediate of general formula (5):
R¹C(=R⁵)R⁶ (5)
which is useful for the production of the tetrazole compound (in which R¹ to R⁶, A and J in the above formulas are as defined in the specification).
