Transition metal complexes as proteasome inhibitors for cancer treatment
Publication date: Available online 11 February 2020Source: Inorganica Chimica ActaAuthor(s): Shagufta, Irshad AhmadAbstractThe discovery of cisplatin, a platinum-based drug, was a major breakthrough in cancer treatment strategies. However, the toxicity and drug resistance associated with cisplatin regulated the drug discovery research towards the rationale development of metal-containing agents with more specific activity and less toxicity and mode of action different from cisplatin and its derivatives. Consequently, the ubiquitin-proteasome pathway (UPP) developed as a novel and encouraging cancer treatment target. The me...

A New Route for the Synthesis of 2,4-Bis(2-pyridyl)-6-(pyridyl)pyrimidines: Synthesis and Characterization of Co(II), Ni(II) Complexes of 2,4,6-Tris(2-pyridyl)pyrimidine
Publication date: Available online 8 February 2020Source: Inorganica Chimica ActaAuthor(s): Jugal Bori, Satyajit Mahata, Vadivelu ManivannanAbstractUsing 2-acetylpyridine, sodium hydroxide and 2-cyanopyridine, 2,4,6-tris(2-pyridyl)pyrimidine (L1) was synthesized in good yields. Similarly, 2,4-bis(2-pyridyl)-6-(3-pyridyl)pyrimidine (L2) and 2,4-bis(2-pyridyl)-6-(4-pyridyl)pyrimidine (L2) were also synthesised by using respective acetylpyridine. 2-Acetylpyridine reacted with sodium hydroxide to produce 2-oxo-2-(2-pyridyl)-1-ethanide, which behaves as a nucleophile towards 2-cyanopyridine. All three pyrimidines are potential ...
