Abstract:
Small molecule inhibitors of biphenyl structure as core backbone have shown a significant effect on PD-1/PD-L1 axis, and 2-amino-pyrimidine structure is a promising privileged scaffold in medicinal chemistry and drug discovery. We designed by combination principles and synthesized 27 novel compounds with N-((2-methyl-[1,1'-biphenyl]-3-yl)methyl)pyrimidin-2-amine as a basic skeletal structure, and their anti-cancer activity was evaluated. Among compounds, 15a-d and 16b displayed strong anti-cancer effects on 9 tested cancer cell lines, in particular, the 16b did the highest inhibitive activity, but against HepG2 cells, and possessed the lowest IC50 value of 2.08 μΜ towards HT-29 cells.

A key example involves the conjugation of cyanide ions, which impair cellular respiration and alter hemoglobin into non-oxygen-carrying cyanmethemoglobin. To neutralize this threat, a sulfur atom from thiosulphate is transferred to the cyanide ion, catalyzed by the enzyme rhodanese, resulting in an inactive compound called thiocyanate. The production of...
