In 2017,Ozdemir, Tugba; Lu, Yu-Chen; Kolemen, Safacan; Tanriverdi-Ecik, Esra; Akkaya, Engin U. published 《Generation of Singlet Oxygen by Persistent Luminescent Nanoparticle-Photosensitizer Conjugates: A Proof of Principle for Photodynamic Therapy without Light》.ChemPhotoChem published the findings.Quality Control of ((1H-Benzo[d][1,2,3]triazol-1-yl)oxy)tris(dimethylamino)phosphonium hexafluorophosphate(V) The information in the text is summarized as follows:

The broader application of photodynamic therapy as a treatment procedure for cancer is hampered by the limited penetration of light through mammalian tissues. Since the photosensitized generation of cytotoxic singlet oxygen requires effective excitation of the tumor-localized photosensitizer, photodynamic action can only be guaranteed for the first few millimeters of the irradiated tissues. In this work, we demonstrated that the phenomenon of persistent luminescence, i.e., delayed emission from certain metal-ion excited states (with crystal defects acting as energy traps), can provide an alternative excitation possibility. Thus, persistent luminescent nanoparticles functionalized by FRET-matching Bodipy sensitizers (FRET=Foerster resonance energy transfer) were excited in situ before administration into a cell culture or an organism. It was found that this system continues to produce singlet oxygen regardless of their location and without any need for continuous photonic excitation. In the part of experimental materials, we found many familiar compounds, such as ((1H-Benzo[d][1,2,3]triazol-1-yl)oxy)tris(dimethylamino)phosphonium hexafluorophosphate(V)(cas: 56602-33-6Quality Control of ((1H-Benzo[d][1,2,3]triazol-1-yl)oxy)tris(dimethylamino)phosphonium hexafluorophosphate(V))

Malaria is a deadly disease killing worldwide hundreds of thousands people each year and the responsible parasite has acquired resistance to the available drug combinations. The four vacuolar plasmepsins (PMs) in Plasmodium falciparum involved in Hb (Hb) catabolism represent promising targets to combat drug resistance. High antimalarial activities can be achieved by developing a single drug that would simultaneously target all the vacuolar PMs. We have demonstrated for the first time the use of soluble recombinant plasmepsin II (PMII) for structure-guided drug discovery with KNI inhibitors. Compounds used in this study (KNI-10742, 10743, 10395, 10333, and 10343) exhibit nanomolar inhibition against PMII and are also effective in blocking the activities of PMI and PMIV with the low nanomolar Ki values. The high-resolution crystal structures of PMII-KNI inhibitor complexes reveal interesting features modulating their differential potency. Important individual characteristics of the inhibitors and their importance for potency have been established. The alkylamino analog, KNI-10743, shows intrinsic flexibility at the P2 position that potentiates its interactions with Asp132, Leu133, and Ser134. The phenylacetyl tripeptides, KNI-10333 and KNI-10343, accommodate different ρ-substituents at the P3 phenylacetyl ring that determine the orientation of the ring, thus creating novel hydrogen-bonding contacts. KNI-10743 and KNI-10333 possess significant antimalarial activity, block Hb degradation inside the food vacuole, and show no cytotoxicity on human cells; thus, they can be considered as promising candidates for further optimization. Based on our structural data, novel KNI derivatives with improved antimalarial activity could be designed for potential clin. use.

COA of Formula: C2H3N3In 2020 ,《Effect of Pore Size on the Separation of Ethylene from Ethane in Three Isostructural Metal Azolate Frameworks》 appeared in Inorganic Chemistry. The author of the article were Jiang, Xue; Zhang, Tao; Cao, Jian-Wei; Zhao, Chong-Kai; Yang, Rong; Zhang, Qiu-Yu; Chen, Kai-Jie. The article conveys some information:

The pore-size effect on ethane adsorption and ethane/ethylene separation in three isostructural metal azolate frameworks (MAF-123-Mn/Zn/Cu) were thoroughly investigated. MAF-123-Mn/Zn/Cu were synthesized by the solvothermal method on a gram scale. Decreasing the pore size from 6.1 to 4.9 Å leads to an increase in the ethane adsorption energy from 23 to 27.5 kJ mol-1 and further ethane/ethylene separation efficiency. Mol. simulations revealed that a shorter ethane-framework interaction distance in MAF-123-Zn than that in MAF-123-Mn is responsible for the increased adsorption energy. Dynamic breakthrough experiments manifest that these metal azolate frameworks can effectively produce high-purity ethylene from ethane in one adsorption step. Exquisite pore-size control by metal alternation was achieved in three metal azolate frameworks for enhanced ethane/ethylene separation The experimental part of the paper was very detailed, including the reaction process of 1H-1,2,3-Triazole(cas: 288-36-8COA of Formula: C2H3N3)

《ab-initio study of hydrogen bond networks in 1,2,3-triazole phases》 was written by Peschel, Christopher; Dressler, Christian; Sebastiani, Daniel. Reference of 1H-1,2,3-TriazoleThis research focused ontriazole hydrogen bond; ab-initio molecular dynamics; crystal structure; diffusion coefficient; fuel cell; hydrogen bond network; pi-pi-stacking; proton conductivity; tautomerism. The article conveys some information:

The research in storage and conversion of energy is an everlasting process. The use of fuel cells is very tempting but up to now there are still several conceptual challenges to overcome. Especially, the requirement of liquid water causes difficulties due to the temperature limit. Therefore, imidazoles and triazoles are increasingly investigated in a manifold of exptl. and theor. publications as they are both very promising in overcoming this problem. Recently, triazoles were found to be superior to imidazoles in proton conduction. An ab-initio mol. dynamics simulation of pure triazole phases for investigating the behavior of both tautomer species of the triazole mol. has never been done. In this work, we investigate the structural and dynamical properties of two different solid phases and the liquid phase at two different temperatures We are able to show how the distinct tautomers contribute to the mechanism of proton conduction, to compute dynamical properties of the four systems and to suggest a mechanism of reorientation in solid phase.
