Tetracyclines (TCs) are the most widely used antibiotics for prevention and treatment of livestock diseases, but they toxic to humans have frequently been detected in water bodies. In this study, physical chemical properties zirconium-based metal organic framework (MOF) UiO-66 its NH2-functionalized congener UiO-66-NH2 were investigated along with batch TC adsorption tests determine effect func...

Functionalizing metal-organic frameworks (MOFs) with amines is a commonly used strategy to enhance their performance in CO2 capture applications. As such, this work, two-step covalently functionalize NH2-containing MOFs short chain polyamines was developed. In the first step, parent MOF, Zn4O(NH2-BDC)3, exposed bromoacetyl bromide (BrAcBr), which readily reacts pendant -NH2 groups on 2-amino-1,...

With the aim to find suitable hydrogen storage materials for stationary and mobile applications, multi-cation amide-based systems have attracted considerable attention, due their unique hydrogenation kinetics. In this work, AmZn(NH2)n (with A = Li, K, Na, Rb) were synthesized via an ammonothermal method. The phases mixed ball milling with LiH form AmZn(NH2)n-2nLiH m 2, 4 n 4, 6), as well Na2Zn(...

BACKGROUND AND PURPOSE Glucose-dependent insulinotropic polypeptide (GIP) affects lipid, bone and glucose homeostasis. High-affinity ligands for the GIP receptor are needed to elucidate the physiological functions and pharmacological potential of GIP in vivo. GIP(1-30)NH2 is a naturally occurring truncation of GIP(1-42). Here, we have characterized eight N-terminal truncations of human GIP(1-30...

In this work, the study of various substituted Kaempferol derivatives is presented. The bond dissociation energies (BDE) have been calculated using B3LYP level and different basis sets in gas-phase. Calculated results show that the BDE values of substituted Kaempferol range from about 77 to100 kcal/mol, demonstrating that Kaempferol is an effective chain-breaking antioxidant that prevents lipid...

Catalytic aerobic oxidation of benzyl alcohol (BnOH) to benzaldehyde (PhCHO) over supported noble metal catalysts has grabbed the attention researchers due critical role PhCHO in numerous industrial syntheses. In present study, a novel catalyst, Pd-P alloy on aminopropyl-functionalized mesoporous silica (NH2-SiO2), was prepared through situ reduction and characterized by BET-BJH analysis, SEM, ...

a simple and efficient one-pot three-component synthesis of the biologically important spirooxindole-4h-pyrans was carried out by the reaction of isatin, activated methylene reagents, and 4-hydroxycoumarin in aqueous medium. sba-pr-nh2 was found to be an efficient heterogeneous nanoporous solid basic catalyst (pore size of 6 nm) which can be easily handled and removed from the reaction mixture ...

FMRF-NH2 peptides which contain a conserved, identical C-terminal tetrapeptide but unique N terminus modulate cardiac contractility; yet, little is known about the mechanisms involved in signaling. Here, the structure-activity relationships (SARs) of the Drosophila melanogaster FMRF-NH2 peptides, PDNFMRF-NH2, SDNFMRF-NH2, DPKQDFMRF-NH2, SPKQDFMRF-NH2, and TPAEDFMRF-NH2, which bind FMRFa-R, were...

[P(NH2)4]Br and [P(NH2)41[N03] have been prepared by anion exchange in liquid ammonia. Single crystals of [P(NH2)4]Br were obtained from an acetonitrile solution in a tempera­ ture gradient between 60 °C and room temperature while attempts to grow single crystals of [P(NH2)4][N 0 3] yielded [P(NH2)4][N 03](OP(NH2)3). Both crystal structures were determined by single crystal X-ray methods at roo...
