In continuation of our effort to optimize the pharmacological profile of [1,2-diamino-1,2-bis(4-fluorophenyl)ethane]dichloridoplatinum(II) complexes, we synthesized [1,2-diamino-1-(4-fluorophenyl)alkanol]dichloridoplatinum(II) analogs. The aim of this study was to evaluate the influence of hydroxyl groups at the C2 moiety on aqueous solubility, lipophilicity, cellular platinum accumulation, and cytotoxicity against MDA-MB-231, U-937, RAJI, and SC-1 cells as well as against cisplatin-sensitive and cisplatin-resistant A2780 and A2780cisR ovarian carcinoma cells. As expected, the OH groups improved the water solubility and decreased the lipophilicity of the neutral ligands, resulting in complexes with favorable pharmacokinetic properties. The cellular uptake of the compounds in MDA-MB-231 and U-937 cells proved to depend on the configuration and showed only a slight correlation with lipophilicity. The most active complexes were R,R/S,S configured, which points to a carrier-mediated mode of action. [threo-1,2-Diamino-1-(4-fluorophenyl)propan]dichloridoplatinum(II) and [threo-2,3-diamino-3-(4-fluorophenyl)propan-1-ol]dichloridoplatinum(II) possessed only low cross-resistance to cisplatin and were up to 10-fold more active in lymphoma cell lines.

Catalytic carbon-carbon bond formation building on reductive coupling is a powerful method for the preparation of organic compounds. The identification of environmentally benign reductants is key for establishing an efficient reductive coupling reaction. Herein an efficient strategy enabling H2 as the sole reductant for the palladium-catalyzed allyl-allyl reductive coupling reaction is described. A wide range of allylamines and allylic alcohols as well as allylic ethers proceed smoothly to deliver the C-C coupling products under 1 atm of H2. Kinetic studies suggested that the dinuclear palladium species was involved in the catalytic cycle.
