The efficient synthesis of a range of biologically significant functionalized 3-aminopyrrolidine-2,5-dione derivatives was achieved from -fused imidazole derivatives (GBB(Groebke-Blackburn-Bienaymé) reaction products) through structural rearrangement by the treatment of aliphatic acid silver salt. The reaction features wide substrates scope, exceptionally mild conditions, moderate-to-good yields and

Octahedral platinum(IV) complexes are promising candidates in the fight against cancer. In order to rationalize the further development of this class of compounds, detailed studies on their mechanisms of action, toxicity, and resistance must be provided and structure activity relationships must be drawn. Herein, we report on theoretical and QSAR investigations of a series of 53 novel bis-, tins-, and tetrakis(carboxylato)platinum(IV) complexes, synthesized and tested for cytotoxicity in our laboratories. The hybrid DFT functional wb97x was used for optimization of the structure geometry and calculation of the descriptors. Reliable and robust QSAR models with good explanatory and predictive properties were obtained for both the cisplatin sensitive cell line CH1 and the intrinsically cisplatin resistant cell line SW480, with a set of four descriptors.
