Adsorptive removal of ciprofloxacin with different dissociated species onto titanate nanotubes

Exploring the specific characteristics of pharmaceuticals and personal care products (PPCPs) via adsorption and degradation are scientific and practical significance to control their release to water matrix. In this work, a good adsorbent and ion-exchange material, i.e., titanate nanotubes (TNTs), was employed for adsorption of ciprofloxacin (CIP, a model PPCPs). The adsorption behaviors and mecha-nisms of CIP with different dissociated species by TNTs were studied through both experimental and theoretical calculations. The multilayered TNTs with high BET surface area (272.3 m(2)/g) and large pore volume (1.26 cm(3)/g) exhibited good adsorption property for CIP. The CIP species (i.e., CIP+, CIP +/-, CIP-) at various pH exhibited significantly different adsorption favorability. Adsorption kinetics and isotherms data revealed that TNTs offered the high uptake for CIP+ (Q(max)= 464.47 mmol/g or 153.90 mg/g at pH 5) than CIP +/- and CIP-. Characterizations indicated the formation of Ti-O-N linkage between CIP molecules and TNTs after adsorption, suggesting the chemical interaction between CIP and TNTs. Density functional theory (DFT) calculations reveal variation on pH affects the protonation/deprotonation state of CIP, and then changes the distribution of molecular orbitals and the electrostatic potential (ESP) energy of CIP. ESP follows the trend as: CIP+ (180.57 kcal/mol) > CIP +/- (146.78 kcal/mol) > CIP- (12.30 kcal/mol), indicating the side of piperazine ring in CIP oriented to TNTs dominates the CIP adsorption. The integrated experimental and theoretical results, for the first time, suggest that ESP energy can serve as the indicator and predictor of adsorption ability for the PPCPs molecules with various speciation, and can help to deeply describe the adsorption mechanism of PPCPs. In addition, TNTs have great application for the removal of PPCPs through adsorption in practical wastewater treatment area. (C) 2020 Elsevier Ltd. All rights reserved.

Photodegradable Hydrogels for Cell Encapsulation and Tissue Adhesion

Hydrogels for wound management and tissue gluing applications have to adhere to tissues for a given time scale and then disappear, either by removal from the skin or by slow degradation for applications inside the body. Advanced wound management materials also envision the encapsulation of therapeutic drugs or cells to support the natural healing process. The design of hydrogels that can fulfill all of these properties with minimal chemical complexity, a stringent condition to favor transfer into a real medical device, is challenging. Herein, we present a hydrogel design with a moderate structural complexity that fulfills a number of relevant properties for wound dressing: it can form in situ and encapsulate cells, it can adhere to tissues, and it can be degraded on demand by light exposure under cytocompatible conditions. The hydrogels are based on starPEG macromers terminated with catechol groups as cross-linking units and contain intercalated photocleavable nitrobenzyl triazole groups. Hydrogels are formed under mild conditions (N-(2-hydroxyethyl)piperazine-N’-ethanesulfonic acid (HEPES) buffer with 9-18 mM sodium periodate as the oxidant) and are compatible with encapsulated cells. Upon light irradiation, the cleavage of the nitrobenzyl group mediates depolymerization, which enables the on-demand release of cells and debonding from tissues. The molecular design and obtained properties reported here are interesting for the development of advanced wound dressings and cell therapies and expand the range of functionality of current alternatives.

Predicting the Shear Viscosity of Carbonated Aqueous Amine Solutions and Their Blends by Using an Artificial Neural Network Model

In the present work, a neural network (NN) model based on quantitative structure-viscosity relationship was implemented for predicting the shear viscosity of CO2-loaded and CO2-free aqueous amine solutions and their blends. A total of 1682 amine + CO, + water viscosity data sets for primary, secondary, and tertiary amines and 220 data points for further accuracy examinations were used. Molecular mechanic methods with CHARMM + CFF force fields were utilized in order to optimize, simulate, and extract the required molecular structure properties. Then, weighted nearest neighbor feature selection algorithm was used for selecting the most influencing descriptors, while cascade-forward NN (CFNN) model was applied for prediction purposes. For generality examinations, CO2-loaded aqueous systems of 3DMA1P(1) + EAE(2), MEA(1) + PZ(2), DMA2P(1) + MEA(2), DEAE(1) + PZ(2), and CO2 + pure water were used to find the solution viscosities, and comparisons were made against experimentations, which showed the quite robustness of the proposed model for the systemsm which were completely unaware of the trained model. Comparison between the values of average relative deviation of the NN model and the most important semiempirical viscosity models showed that CFNN model outperforms the other alternatives.

Piperazine ring formation by a single-module NRPS and cleavage by an alpha-KG-dependent nonheme iron dioxygenase in brasiliamide biosynthesis

Brasiliamides are a class of piperazine-containing alkaloids produced by Penicillium brasilianum with a range of pharmaceutical activities. The mechanism of brasiliamide biosynthesis, including piperazine ring formation and multiple tailoring modifications, still remains unclear. In this study, the biosynthetic gene cluster of brasiliamides, brs, was identified from the marine-derived fungal strain Penicillium brasilianum WZXY-M122-9. Deletion of a histone deacetylase-encoding gene using a CRISPR/Cas9 gene editing system led to the production of a new compound, namely brasiliamide I (1). The brs-encoded single-module nonribosomal peptide synthetase (NRPS) BrsA is involved in the formation of the piperazine skeleton of brasiliamides. Full-length BrsA protein (113.6 kDa) was purified, and reconstitution of enzymatic activity in vitro confirmed that BrsA stereoselectively accepts l-phenylalanine as the substrate. Multiple deletion of tailoring genes and analysis of purified proteins in vitro enabled us to propose a brasiliamide biosynthetic pathway. In the tailoring steps, an alpha-ketoglutarate (KG)-dependent nonheme iron dioxygenase, BrsJ, was identified to catalyze piperazine ring cleavage during biosynthesis of brasiliamide A (2).

Coal-Tar Dye-based Coordination Cages and Helicates

A strategy to implement four members of the classic coal-tar dye family, Michler’s ketone, methylene blue, rhodamine B, and crystal violet, into [Pd2L4] self-assemblies is introduced. Chromophores were incorporated into bis-monodentate ligands using piperazine linkers that allow to retain the auxochromic dialkyl amine functionalities required for intense colors deep in the visible spectrum. Upon palladium coordination, ligands with pyridine donors form lantern-shaped dinuclear cages while quinoline donors lead to strongly twisted [Pd2L4] helicates in solution. In one case, single crystal X-ray diffraction revealed rearrangement to a [Pd3L6] ring structure in the solid state. For nine examined derivatives, showing colors from yellow to deep violet, CD spectroscopy discloses different degrees of chiral induction by an enantiomerically pure guest. Ion mobility mass spectrometry allows to distinguish two binding modes. Self-assemblies based on this new ligand class promise application in chiroptical recognition, photo-redox catalysis and optical materials.
