- Description: A small library of nine, novel 2, 4-diarylquinoline derivatives has been prepared in high yield via convenient one-or two-step routes from a series of substituted 2-aminobenzophenones. None of the products exhibited toxicity at 20 μM against human cervix adenocarcinoma (HeLa) cells, while many of them exhibited encouraging trypanocidal activity against T. brucei brucei (a parasite responsible for African cattle trypanosomiasis)-some with IC50 values in the range 2.8–6.2 μM.

- Description: Substituted 3-furanomethyl phosphate esters and their corresponding phosphoric acids have been prepared as conformationally restricted analogues of DOXP, the natural substrate for Plasmodium falciparum 1-deoxyD-xylulose-5-phosphate reductoisomerase (PfDXR), and fosmidomycin, an established inhibitor. Saturation Transfer Difference (STD) NMR analysis and in silico docking data suggest the potential of such compounds as PfDXR inhibitors.

- Description: The capacity of the nitrogen nucleophile, 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) to reduce aryl- and heteroaryl disulfides to the corresponding mercaptans is demonstrated. While dicarboxylated disulfide analogues afford the mono-DBU disulfide salts, as confirmed by X-ray crystallography, the corresponding methyl esters are cleaved normally.
