Cisplatin is one of the most successful antitumor agents, yet also restricted by its poor cellular uptake and low selectivity. Since 3-(2-nitrophenyl) propionic acid (NPPA) has been reported as a bioreductive prodrug moiety, herein we combined NPPA with cisplatin (compound 1) to improve its lipophilicity and targetability and then to improve the antitumor outcomes. In addition, compound 2 possessing 3-phenyl propionic acid (PPA) was also synthesized as a comparison to test the influence of the NPPA to the cytotoxicity, since PPA was not a bioreductive moiety. Bioevaluations showed that 1 displayed more potent antitumor potency than cisplatin and 2, suggesting Pt(II) complexes possessing NPPA groups may be a good strategy for future platinum drug discovery.

A novel universalN-transfer reagent for direct and effective transformation of α-amino ketones, acetamides, and esters to the corresponding α-diazo products under mild basic conditions has been developed. This one-step synthetic approach not only allows for generation of α-substituted-α-diazo carbonyl compounds from α-amino acid derivatives but also permits preparation of α-diazo dipeptides fromN-terminal dipeptides (32 examples, up to 91%).

, p. 174 - 176 (2015/03/04)
Ortho-, meta- and para-isomers of (3,3,3-trifluoropropyl)aniline have been prepared in 60-70 g amount from the corresponding nitrobenzaldehydes in three steps. The key synthesis step was a transformation of the carboxylic group of 3-(nitrophenyl)propanoic acids into the trifluoromethyl group by SF4.
