Passos, Helena published the artcileSelective Sequential Recovery of Zinc and Copper from Acid Mine Drainage, Computed Properties of 23616-79-7, the publication is ACS Sustainable Chemistry & Engineering (2021), 9(10), 3647-3657, database is CAplus.

The observed imbalance between the unsustainable consumption of available natural metal resources and finite deposits makes the recovery and recycling of metals from metal-containing wastes an imperative. Here, ionic-liquid-based aqueous biphasic systems (IL-based ABSs) are proposed as an efficient alternative for selective metal recovery from real copper acid mine drainage (AMD) effluents. ABSs composed of different ILs and Na₂SO₄ were evaluated for Zn, Al, Cu, Co, and Ni extraction from both model solutions and AMD samples. It is shown that IL composed of thiocyanate anion ([SCN]^–) presented a remarkable ability to extract metals from AMD through the formation of stable metal complexes. The addition of NaSCN to ABSs composed of tetrabutylammonium chloride ([N₄₄₄₄]Cl) allowed to mimic the use of [SCN]-based IL with addnl. advantages: tunable metal selectivity by the concentration of [SCN]^– added to the ABS and a reduction in system cost and environmental impact. Furthermore, at the [SCN]^– concentration range studied here, the formation of a hydrophobic salt composed of IL cations and metal complex anions is observed, which allows the selective extraction and recovery of transition metals in a single step. The IL-rich phase recyclability in three extraction cycles is demonstrated, showing the possibility to recover two times more Zn than with a single extraction cycle while using the same amount of IL and thiocyanate. Salt-rich phases were also recycled in a new IL-based ABS for the subsequent Cu extraction and recovery. These results allow the development of a sustainable process for the selective sequential recovery of transition metals from AMD.

He, Xiaohui published the artcileIdentification of Potent and Selective RIPK2 Inhibitors for the Treatment of Inflammatory Diseases, Recommanded Product: 3-Chloro-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol, the publication is ACS Medicinal Chemistry Letters (2017), 8(10), 1048-1053, database is CAplus and MEDLINE.

NOD2 (nucleotide-binding oligomerization domain-containing protein 2) is an internal pattern recognition receptor that recognizes bacterial peptidoglycan and stimulates host immune responses. Dysfunction of NOD2 pathway has been associated with a number of autoinflammatory disorders. To date, direct inhibitors of NOD2 have not been described due to tech. challenges of targeting the oligomeric protein complex. Receptor interacting protein kinase 2 (RIPK2) is an intracellular serine/threonine/tyrosine kinase, a key signaling partner, and an obligate kinase for NOD2. As such, RIPK2 represents an attractive target to probe the pathol. roles of NOD2 pathway. To search for selective RIPK2 inhibitors, the authors employed virtual library screening (VLS) and structure based design that eventually led to a potent and selective RIPK2 inhibitor 8 (4-(7-ethoxy-6-(isopropylsulfonyl)imidazo[1,2-a]pyridin-3-yl)-6-fluoropyridin-2-amine) with excellent oral bioavailability, which was used to evaluate the effects of inhibition of RIPK2 in various in vitro assays and ex vivo and in vivo pharmacodynamic models.
