Structure activity relationship analysis of antiproliferative cyclic C5-curcuminoids without DNA binding: Design, synthesis, lipophilicity and biological activity
shortcomings. The synthesis of twenty cyclic C5-curcuminoids is described in this study in order to gain more insight into their anticancer structure-activity relationship (SAR). The design of their synthesis included four different cyclanones and five substituted aromatic aldehydes to form four, five-membered subgroups. These model compounds were evaluated in vitro for antiproliferative activity in an XTT

3-dipolar cycloaddition reaction of 1-alkyl-3,5-bis(arylidene)-4-piperidones 11–25 with azomethine ylides (generated by the condensation of isatins 26–28 with sarcosine 29). The single crystal X-ray studies of 46 and 48 supported the regio- and stereoselectivity of the reaction. Most of the synthesized spiro-indoles exhibited potent antitumor properties against the HeLa (cervical cancer) cell line through

AbstractA new procedure is developed for the synthesis of dissymmetric bisarylidene derivatives of two cyclohexanone analogues. Under mild ultrasonic/organocatalytic conditions, the first aldehyde reacts with the ketone to give the monoarylidene intermediate which subsequently condenses with the second aldehyde upon addition of NaOH/MeOH to the reaction mixture. Both condensations proceed in one pot
6-naphthyridines and pyrano[3,2-c]pyridines were selectively synthesized via microwave-assisted reactions controlled by the nature of the solvent. This has resulted in an efficient and promising synthetic method for constructing the 1,6-naphthyridine and pyrano[3,2-c]pyridine skeletons. solvent-dependent chemoselectivity - 1,6-naphthyridines - pyrano[3,2-c]pyridines

An efficient method for synthesis of pyrano[3,2-<i>c</i>]pyridine derivatives under microwave irradiation
A series of pyrano[3,2-c]pyridine derivatives were synthesized via reactions of 3,5-dibenzylidene-piperidin-4-one and malononitrile in N,N-dimethylformamide undermicrowave irradiation. It is a simple, efficient, and promising synthetic method to construct pyrano[3,2-c]pyridine skeleton. J. Heterocyclic Chem., (2009).
