Singh, Kunwar P. published the artcileMultispecies QSAR Modeling for Predicting the Aquatic Toxicity of Diverse Organic Chemicals for Regulatory Toxicology, Quality Control of 350-30-1, the publication is Chemical Research in Toxicology (2014), 27(5), 741-753, database is CAplus and MEDLINE.

The research aims to develop multispecies quant. structure-activity relationships (QSARs) modeling tools capable of predicting the acute toxicity of diverse chems. in various Organization for Economic Co-operation and Development (OECD) recommended test species of different trophic levels for regulatory toxicol. Accordingly, the ensemble learning (EL) approach based classification and regression QSAR models, such as decision treeboost (DTB) and decision tree forest (DTF) implementing stochastic gradient boosting and bagging algorithms were developed using the algae (P. subcapitata) exptl. toxicity data for chems. The EL-QSAR models were successfully applied to predict toxicities of wide groups of chems. in other test species including algae (S. obliguue), daphnia, fish, and bacteria. Structural diversity of the selected chems. and those of the end-point toxicity data of five different test species were tested using the Tanimoto similarity index and Kruskal-Wallis (K-W) statistics. Predictive and generalization abilities of the constructed QSAR models were compared using statistical parameters. The developed QSAR models (DTB and DTF) yielded a considerably high classification accuracy in complete data of model building (algae) species (97.82%, 99.01%) and ranged between 92.50%-94.26% and 92.14%-94.12% in four test species, resp., whereas regression QSAR models (DTB and DTF) rendered high correlation (R²) between the measured and model predicted toxicity end-point values and low mean-squared error in model building (algae) species (0.918, 0.15; 0.905, 0.21) and ranged between 0.575 and 0.672, 0.18-0.51 and 0.605-0.689 and 0.20-0.45 in four different test species. The developed QSAR models exhibited good predictive and generalization abilities in different test species of varied trophic levels and can be used for predicting the toxicities of new chems. for screening and prioritization of chems. for regulation.

Kumar, Atul published the artcileDesign and synthesis of new bioisosteres of spirooxindoles (MI-63/219) as anti-breast cancer agents, Quality Control of 4584-49-0, the publication is Bioorganic & Medicinal Chemistry (2015), 23(4), 839-848, database is CAplus and MEDLINE.

The authors report herein the design and synthesis of bioisosteres of spirooxindole (MI-63/219), a small-mol. inhibitors of the MDM2-p53 interaction as antibreast cancer agents. Compound I has been exhibiting significant antiproliferative activity in nude mice bearing MCF-7 xenograft tumor. The compound I was found to act via modulation of MDM2 and p53 expression in breast cancer cells expressing wild type p53. Compound I stimulated p53 activation, caused modulation of downstream effectors p21, pRb, and cyclin D1 which regulate cell cycle. Thus, compound triggered G1-S phase cell cycle arrest, which was evident by flow cytometric anal. of treated breast cancer cells. Thus, compound I restores the p53 function, which triggers mol. events consistent with cell cycle arrest at G1/S phase.

Optimization of a series of uracils bearing a 2-fluoro- or 2-chloro-3-methoxyphenyl group at the 5-position resulted in compounds such as I (R = Me, X = CF₃, Y = F, Cl) with subnanomolar binding affinity at the human GnRH receptor. While the 2-fluoro-3-methoxyphenyl compound I (R = X = Y = Me) was characterized as a mixture of interchangeable atropisomers, the diastereoisomers of 2-chloro-3-methoxyphenyl analogs were separated It was found that the aR-atropisomer was much more potent than the aS-isomer based on the X-ray crystal structure of I (R = CH₂OH, X = CF₃, Y = Cl).

Wang, Tong published the artcilepH-controlled reversible deep-eutectic solvent based enzyme system for simultaneous extraction and in-situ separation of isoflavones from Pueraria lobata, HPLC of Formula: 23616-79-7, the publication is Separation and Purification Technology (2022), 120992, database is CAplus.

In this study, we developed an efficient and green pH-controlled reversible deep-eutectic solvents (DESs) based enzyme system for efficient extraction, transformation and in-situ separation of natural products from herbs. As a case study, seven isoflavones in the root of Pueraria lobata were selected as target compounds A series of DESs were firstly prepared and the extraction efficiency for target compounds with or without cellulase catalysis was investigated. We found that [N4444][Cl]:ethylene glycol (1:2) with cellulase addition show the highest extraction efficiency for isoflavones. More importantly, the phase behavior of [N4444][Cl]:ethylene glycol (1:2) based cellulase system was found to be pH-controlled. When pH is 5.0, the system is a homogeneous single-phase system, which is conducive to the extraction of natural products. When pH is 6.4, the system changes from the single-phase to the heterogeneous two-phase, to realize the in-situ separation of the compounds Therefore, by adjusting the pH of the system, the in-situ separation of isoflavones was successfully realized with high recovery yields. The pH-controlled DESs based enzyme-assisted extraction system overcomes the incompatibility between enzyme catalysis and conventional organic solvent in extraction, which could efficiently extract seven isoflavones from Pueraria lobata root.

Liu, Tian published the artcileA crystal structure-guided rational design switching non-carbohydrate inhibitors’ specificity between two β-GlcNAcase homologs, Product Details of C4H5ClN2S, the publication is Scientific Reports (2014), 6188, database is CAplus and MEDLINE.

Selective inhibition of function-specific β-GlcNAcase has great potential in terms of drug design and biol. research. The sym. bis-naphthalimide M-31850 was previously obtained by screening for specificity against human glycoconjugate-lytic β-GlcNAcase. Using protein-ligand co-crystallization and mol. docking, we designed an unsym. dyad of naphthalimide and thiadiazole, Q2, that changes naphthalimide specificity from against a human glycoconjugate-lytic β-GlcNAcase to against insect and bacterial chitinolytic β-GlcNAcases. The crystallog. and in silico studies reveal that the naphthalimide ring can be utilized to bind different parts of these enzyme homologs, providing a new starting point to design specific inhibitors. Moreover, Q2-induced closure of the substrate binding pocket is the structural basis for its 13-fold increment in inhibitory potency. Q2 is the first non-carbohydrate inhibitor against chitinolytic β-GlcNAcases. This study provides a useful example of structure-based rationally designed inhibitors as potential pharmaceuticals or pesticides.
