Diamondoid Hydrazones and Hydrazides: Sterically Demanding Ligands for Sn/S Cluster Design
摘要:
A series of new adamantane and diamantane hydrazides was synthesized and coupled with organo-functionalized Sn/S clusters of the general type [(RSn4S6)-Sn-I] (R-I = CMe2CH2COMe) to form diamondoid-decorated Sn/S dusters. The new ligand precursors as well as the resulting hybrid compounds were analyzed by NMR spectroscopy, mass spectrometry, and single-crystal X-ray diffraction, and first insights were gained in the installation of sterically highly demanding and at the same time rigid mono-, di-, and trifunctionalized diamondoid ligands on tetrelchalcogenide cages.

a hydrazone of 5-nitro-2-furaldehyde is used therapeutically against Trypanosoma brucei and Trypanosoma cruzi infections. Exploiting our previous observation that adamantane derivatives display trypanocidal activity, we designed and synthesised a range of hydrazones of 5-nitro-2-furaldehyde with adamantane alkanohydrazides. The most promising compounds had >20 times greater activity (IC50 ∼ 100 nM)
