“…As shown in Figures S3 and S4, the bands at 3420 and 3410 cm –1 are related to the stretching vibration of N–H bond in Cu-CP-1 and Cu-CP-2 , respectively . The bands at 1680 and 1620 cm –1 is related to the stretching vibration of CO and CC in Cu-CP-1 and Cu-CP-2 , respectively . As shown in Figure S5, Cu-CP-1 loses weight in the range of 25–410 °C, with a weight loss of approximately 85.12% which can be attributed to the removal of ligands 3-bbpa and 1,2,4-HBTC.…”

Assuming that the final residuals are CuO and Cu, the final residual is 14.81%, which is close to the calculated value of 14.88%.…”

This article reports the design and synthesis of two copper-based coordination polymers (Cu-CPs) constructed from mixed ligands containing a bis-pyridine-bis-amide group and trimellitic acid. By using substituent-regulated acids, the simplified two-dimensional (2D) double layers for the Cu-CP-1 and Cu-CP-2 possess different grid windows, which can be served as a kind of urease inhibitors (UIs) and their inhibition mechanisms were explored in details. The results show that both Cu-CPs exhibited good urease inhibitory activity, and the inhibitory activities of all derivatives were higher than that of the standard thio urea, with UI-2 exhibiting better urease inhibitory performance. To better understand the potential mechanism of urease inhibition by these CPs, enzyme kinetics analysis was performed using Lineweaver− Burk (L−B) plots at different inhibitor concentrations, which indicated that UI-1 and UI-2 exhibited noncompetitive inhibitory nature. Additionally, molecular docking confirmed the binding interactions of UI-1 and UI-2 with the active site of urease. The urease inhibition experiments were successfully verified, and the effects of the structures of CPs on urease inhibition were measured through DFT calculations.
