Regiospecific microwave-assisted synthesis and cytotoxic activity against human breast cancer cells of (RS)-6-substituted-7- or 9-(2,3-dihydro-5H-1,4-benzodioxepin-3-yl)-7H- or -9H-purines
摘要:
Extended studies on the synthesis and pharmacological evaluation of (RS)-6-substituted-7 or 9-(2,3-dihydro-5H-1,4-benzodioxepin-3-yl)-7H- or -9H-purines are presented. The microwave-assisted organic synthesis has provided faster access to the target compounds with the advantage of selective obtaining the N-7 ' or N-9 ' regioisomers simplifying their isolation. To test the behaviour of the products (including the purine bases) on cellular systems, cytotoxic activity against the MCF-7 human breast cancer cell line was determined, and the three most active compounds were used to study the cell cycle distribution and apoptosis in the MCF-7 cell line.

Heteroarenes of commercial relevance such as purines and pyrimidines were also found to be useful substrates for the reported transformation. The commercial drug Imuran (azathioprine) was synthesized as an example, and its preparation could be optimized. DFT studies were performed to understand the electronic effects of the tested ligands on the catalytic reaction.

-alkyl-substituted purines in a combinatorial and traceless fashion. The methods involve, in some embodiments, Mitsunobu alkylation of 2-fluoro-6-phenylsulfenylpurine at N9 with alcohols in solution, followed by C2-capture of the purine core with a resin-bound amine and subsequent oxidation and displacement of the C6 sulfonyl group with amines and anilines.

A highly efficient and an unprecedented hexafluoro-2-propanol, promoting low-temperature aromatic nucleophilic substitutions of chloroheteroarenes, has been performed using thiols and (secondary) amines under base free and metal-free conditions. The developed protocol also provides excellent regio-control for the selective functionalization of dichloroheteroarenes, while the utility of the protocol was demonstrated by the modification of a commercially available drug ceritinib.
