Artificial enzyme mimics have recently emerged as alternative biocatalysts for overcoming the intrinsic fragility of natural enzyme in practical applications. However, current researches regarding mimetic enzymes are still confined to very few reaction types, with artificial oxidoreductases as dominance. Herein, inspired by nature, we designed and fabricated a range of Zn-Triazole coordination polymers (ZnTazs) that presented similar co-ordination structures with the active site of natural carbonic anhydrase. (CA II). These synthesized compounds exhibited inherently mimetic function with natural CA for catalyzing the hydrolysis of p-nitrophenyl acetate (p-NPA). Especially, the initial hydrolysis rate (V-0) of p-NPA catalyzed by ZnTaz-1 (Zn-5(bta)(6)(NO3)(4) center dot H2O) and ZnTaz-2 (Zn-3(OH)(2)(btca)(2) center dot DMF center dot 4 H2O) reached 42.1 and 73.8 nM.s(-1), respectively. Meanwhile, ZnTaz-1 and ZnTaz-2 showed favorable recyclability, and excellent stability towards various pH values and organic solvents, which are of great significance for practical employment. Moreover, they could also promote the efficient hydration and sequestration of greenhouse gas CO2 in aqueous medium. Based on this work, we aim to provide more theoretical and practical basis for rational design of CA mimics from the inspiration of natural enzyme, as well as propose a potential strategy for tackling the CO2 crisis.

A novel series of acetamide-substituted derivatives and two prodrugs of doravirine were designed and synthesized as potent HIV-1 NNRTIs by employing the structure-based drug design strategy. In MT-4 cell-based assays using the MTT method, it was found that most of the new compounds exhibited moderate to excellent inhibitory potency against the wild-type (WT) HIV-1 strain with a minimum EC50 value of 54.8 nM. Among them, the two most potent compounds 8i (EC50 = 59.5 nM) and 8k (EC50 = 54.8 nM) displayed robust activity against WT HIV-1 with double-digit nanomolar EC50 values, being superior to lamivudine (3TC, EC50= 12.8 mu M) and comparable to doravirine (EC50= 13 nM). Besides, 8i and 8k shown moderate activity against the double RT mutant (K103N + Y181C) HIV-1 RES056 strain. The HIV-1 RT inhibition assay further validated the binding target. Molecular simulation of the representative compounds was employed to provide insight on their structure-activity relationships (SARs) and direct future design efforts. Finally, the aqueous solubility and chemical stability of the prodrugs 9 and 10 were investigated in detail.

A thermo-responsive copolymer with a gas-switchable LCST-type phase transition was synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization of N-isopropylacrylamide (NIPAM) and glycidyl methacrylate (GMA), followed by post-polymerization functionalization with sodium 3-amino-1,2,4-triazole (ATANa). Incorporating ionic moieties provides an elevated cloud point of 61 degrees C. Importantly, both CO2 and SO2 cause a reduction in the cloud point of the polymer solution. The CO2-triggered system can be easily and fully recovered to its initial state by introducing an inert gas (e.g. N-2), whereas the SO2-triggered system shows only partial recovery. The pH-dependent phase transition behaviors confirm that the gas bubbling-induced pH changes contribute to the gas-switchable cloud point of P(NIPAM-co-(GMA-ATANa)). In addition, P(NIPAM-co-(GMA-ATA)) (ATA: 3-amino-1,2,4-triazole), a counterpart of P(NIPAM-co-(GMA-ATANa)), was prepared and the relevant solution phase transition behavior was studied. Its cloud point shift in response to gas bubbling and pH adjustment is opposite to that of P(NIPAM-co-(GMA-ATANa)), indicating that the latter does not result from the protonation of amidine groups. Alternatively, a reversible H+-induced decrease in hydrophilicity was thus proposed. This contribution enriches the family of thermo-responsive polymers by introducing gas-sensitive polyelectrolytes and also broadens the scope of gas-responsive smart materials.

Aminotriazole isomers with high nitrogen content show potential affinity for U(VI). Combining the advantages of both aminotriazole and cellulose, two n-aminotriazole isomers modified cellulose microspheres (n-ATARs, n = 3, 4) were newly prepared as adsorbents via radiation technology. Batch adsorption experiments showed that n-ATARs possessed good adsorption capacity of U(VI) in the order of 3-ATAR > 4-ATAR, and the adsorption process followed the Langmuir-Freundlich isotherm model and the pseudo-second-order kinetic model. Both n-ATARs exhibited good selectivity and reusability. Besides, 3-ATAR and 4-ATAR were more suitable for the extraction of trace amount of U(VI) from the contaminated groundwater and the simulated seawater, respectively. The effect of amino position on triazole ring on adsorption behavior of n-ATAR was studied and explained by DFT calculation. Finally, the adsorption mechanism of U(VI) onto n-ATARs was revealed to be inner-sphere complexation via different 1:1 or 1:2 coordination models by FTIR, MS, XPS analysis and DFT calculation.

In this work, (Z)-N-benzoyl-N ‘-(1H-1,2,4-triazol-3-yl)carbamimidothioic acid and its Mn(II), Co(II), Cu(II) and Cd(II) complexes were introduced for the first time. This carbonyl thiourea ligand was prepared by the reaction of 1H-1,2,4-triazol-3-amine with benzoyl isothiocyanate. The structural elucidation of these compounds was performed using elemental analysis and spectral and magnetic measurements. Octahedral structures of all complexes, except Cd(II) complex with a tetrahedral geometry, were confirmed by applying DFT structural optimization. The thermal decomposition behaviour of metal complexes of carbonyl thiourea ligand is discussed. The calculation of kinetic parameters for prepared complexes (E-a, A, Delta H*, Delta S* and Delta G*) of all thermal degradation stages has been evaluated using two comparable approaches. Antimicrobial and ABTS-antioxidant studies indicated potent activity of Cd(II) complex compared with the other investigated compounds. The cytotoxic activity of the prepared compounds was investigated in vitro. The results indicated potent activity of Mn(II) complex against both HePG2 (liver carcinoma) and MCF-7 (breast carcinoma) cancer cells.
