Synthesis, structure determination and in vitro antiproliferative assay of a series of novel ferrocenenyl hydrazones containing 4-halopyridazin-3(2H)-one fragment(s) and three representative N-arylsubstituted (Sp)-ferroceno[d] pyridazinones are presented. The model compounds can be considered as different assemblies of the potential binding sites capable of establishing interactions including hydrogen bonds and pi-pi interactions with the relevant residues of biomolecules. Their in vitro antiproliferative effect was investigated against four tumorous cell lines by the 3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide (MTT)-assay. Our data indicate that bis-hydrazone of 1,1?-diformylferrocene carrying N-benzyl substituents and a chloropyridazinyl-substituted ferroceno[d]pyridazinone display significant activity on each cell lines investigated. The efficiency of the latter drug candidate and one N-benzyl mono-hydrazone on A2870 cell line is comparable to that of cisplatin. The constitution and relative configuration of the model compounds were established by 1H, 13C and 15N NMR methods. The structures of a mono- and bis-ferrocenylhydrazone containing 4-bromopyridazinone unit(s) were confirmed by single crystal X-ray diffraction.

Readily available alpha-amino aldehydes, incorporating a methylthiomethyl (MTM) protecting group on nitrogen, are shown to be efficient substrates in Rh-catalyzed alkyne hydroacylation reactions. The reactions are performed under mild conditions, employing a small-bite-angle bis-phosphine ligand, allowing for good functional group tolerance with high stereospecificity. Amino aldehydes derived from glycine, alanine, valine, leucine, phenylalanine, isoleucine, serine, tryptophan, methionine, and cysteine were successfully employed, as was an enantiomerically enriched alpha-OMTM-aldehyde derived from phenyllactic acid. The synthetic utility of the alpha-amino enone products is demonstrated in a short enantioselective synthesis of the natural product sphingosine.

Understanding the mechanism of action (MOA) of bioactive natural products will guide endeavor to improve their cellular activities. Artemisinin and its derivatives inhibit cancer cell proliferation, yet with much lower efficiencies than their roles in killing malaria parasites. To improve their efficacies on cancer cells, we studied the MOA of artemisinin using chemical proteomics and found that free heme could directly activate artemisinin. We then designed and synthesized a derivative, ART-TPP, which is capable of targeting the drug to mitochondria where free heme is synthesized. Remarkably, ART-TPP exerted more potent inhibition than its parent compound to cancer cells. A clickable probe ART-TPP-Alk was also employed to confirm that the attachment of the TPP group could label more mitochondrial proteins than that for the ART derivative without TPP (AP1). This work shows the importance of MOA study, which enables us to optimize the design of natural drug analogues to improve their biological activities.

A series of enantioenriched ferrocenyl monophosphines imbued with both central and planar chirality were obtained catalytically (80?99% ee) via the kinetic resolution of 1,2-disubstituted planar chiral ferrocenyl enone racemates. The synthetic approach utilized a chiral palladacycle to facilitate the asymmetric hydrophosphination (AHP) as a means to achieve high stereoselectivity. The enantioenriched ferrocenylphosphine products could be protected and further recrystallized to obtain ees up to 99%. The modularity of the phosphine framework obtained was demonstrated via derivatization of its functional handles via a simple nucleophilic substitution to yield optically pure bisphosphines.

The synthesis and characterisation of a series of ferrocenylaminoalcohols is reported. 1,2-Aminoalcohol compounds were prepared from the respective ferrocene aldehydes via reaction with trimethylsilylcyanide followed by reduction with LiAlH4. This series includes the ferrocene derivative 1,1?-dimethyl-3-(2-amino-1-hydroxyethyl)ferrocene 1, which is used as a redox mediator to glucose oxidase in a commercial biosensor for determining blood glucose levels in diabetics. The aminoalcohol derivatives are included in a structure-activity study involving the electrochemical determination of the mediation rates of a range of systematically substituted ferrocenes with glucose oxidase.
