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.

On the basis of ATP adenine, a series of adenine and purine derivatives was prepared and tested for their ability to inhibit a spectrum of disease-related kinases. There has been scant research investigating the potential of cosubstrate derived kinase inhibitors for other kinases than CDKs. Our inhibitor design combined the purine system from the original cosubstrate ATP and phenyl moieties in order to explore possible interactions with the different regions of the ATP binding site in several disease-related protein kinases. There have been a number of hits for the assayed substances, which led us to conclude that the spectrum of compounds may prove to be a valuable tool kit for the evaluation of bonding and selectivity patterns for a wide variety of kinases.
Copper Catalyzed Three-Component Ullmann C–S Coupling in PEG for the Synthesis of 6-Aryl/alkylthio-purines
A series of aryl sulfide derivatives was synthesized and evaluated for their anti-melanogenic activities. Several compounds, including 3e, 3i and 3q exhibited good anti-melanogenic activities. Among the derivatives, compound 3i showed good inhibitory effects against melanin synthesis and showed no toxicity in reconstituted human eye and skin tissues.
