CAMKK2 is a serine/threonine kinase and an activator of AMPK whose dysregulation is linked with multiple diseases. Unfortunately, STO-609, the tool inhibitor commonly used to probe CAMKK2 signaling, has limitations. To identify promising scaffolds as starting points for the development of high-quality CAMKK2 chem. probes, we utilized a hinge-binding scaffold hopping strategy to design new CAMKK2 inhibitors. Starting from the potent but promiscuous disubstituted 7-azaindole GSK650934, a total of 32 compounds, composed of single-ring, 5,6-, and 6,6-fused heteroaromatic cores, were synthesized. The compound set was specifically designed to probe interactions with the kinase hinge-binding residues. Compared to GSK650394 and STO-609, 13 compounds displayed similar or better CAMKK2 inhibitory potency in vitro, while compounds 13g and 45 had improved selectivity for CAMKK2 across the kinome. Our systematic survey of hinge-binding chemotypes identified several potent and selective inhibitors of CAMKK2 to serve as starting points for medicinal chem. programs.

Major depressive disorder (MDD) is one of the most common psychiatric disorders, the diagnosis, treatment of MDD are major clin. issues. However, there is a lack of effective biomarkers, drugs diagnosis, therapeutics of MDD. In the present study, bioinformatics anal. combined with an exptl. verification strategy was used to identify biomarkers, paeoniflorin targets for MDD diagnosis, treatment. Based on network pharmacol., we obtained potential targets, pathways of paeoniflorin as an antidepressant through multiple databases. We then constructed a protein-protein interaction network, performed enrichment analyses. According to the results, we performed in vivo, in vitro exptl. validation. The results showed that paeoniflorin may exert an antidepressant effect by regulating cell inflammation, synaptic function, NF-κB signaling pathway, intestinal inflammation. NPM1, HSPA8, HSPA5, HNRNPU, TNF are the targets of paeoniflorin treatment. In addition, we demonstrated that paeoniflorin inhibits inflammatory cytokine production via the p38MAPK/NF-κB pathway, has neuroprotective effects on the synaptic structure. Our findings provide valuable evidence for the diagnosis, treatment of MDD.

Chen, Xingmei; Dang, Limin; Yang, Hai; Huang, Xianwei; Yu, Xinliang published the artcile< Machine learning-based prediction of toxicity of organic compounds towards fathead minnow>, Name: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is SAR Pimephales promelas organic compound toxicity machine learning.

Predicting the acute toxicity of a large dataset of diverse chems. against fathead minnows (Pimephales promelas) is challenging. In this paper, 963 organic compounds with acute toxicity towards fathead minnows were split into a training set (482 compounds) and a test set (481 compounds) with an approx. ratio of 1 : 1. Only six mol. descriptors were used to establish the quant. structure-activity/toxicity relationship (QSAR/QSTR) model for 96 h pLC50 through a support vector machine (SVM) along with genetic algorithm. The optimal SVM model (R2 = 0.756) was verified using both internal (leave-one-out cross-validation) and external validations. The validation results (qint2 = 0.699 and qext2 = 0.744) were satisfactory in predicting acute toxicity in fathead minnows compared with other models reported in the literature, although our SVM model has only six mol. descriptors and a large data set for the test set consisting of 481 compounds

Postoperative management of lower grade gliomas (grade 2 and 3) is heterogeneous. The American Radium Society’s brain malignancies panel systematically reviewed and evaluated the literature to develop consensus guidelines addressing timing of postoperative therapy, monotherapy versus combined modality therapy, type of chemotherapy used with radiotherapy, and radiotherapy dose. Thirty-six studies were included. Using consensus methodology (modified Delphi), the panel voted upon representative case variants using a 9-point appropriateness scale to address key questions. Voting results were collated to develop summarized recommendations. Following gross-total surgical resection, close surveillance is appropriate for well-selected grade 2, IDH-mutant oligodendrogliomas or astrocytomas with low-risk features. For grade 2 gliomas with high-risk features or any grade 3 glioma, immediate adjuvant therapy is recommended. When postoperative therapy is administered, radiation and planned chemotherapy is strongly recommended over monotherapy. For grade 2 and 3 IDH-mutant oligodendrogliomas and astrocytomas, either adjunctive PCV (procarbazine, lomustine, vincristine) or temozolomide is appropriate. For grade 3 IDH-mutant astrocytomas, radiotherapy followed by temozolomide is strongly recommended. The recommended radiotherapy dose for grade 2 gliomas is 45-54 Gy/1.8-2.0 Gy, and for grade 3 gliomas is 59.4-60 Gy/1.8-2.0 Gy. While multiple appropriate treatment options exist, these consensus recommendations provide an evidence-based framework to approach postoperative management of lower grade gliomas.

Wang, Baobei; Pan, Xueshan; Wang, Fang; Liu, Lulu; Jia, Jing published the artcile< Photoprotective carbon redistribution in mixotrophic Haematococcus pluvialis under high light stress>, HPLC of Formula: 112-63-0, the main research area is Haematococcus high light stress photoprotective carbon redistribution; Astaxanthin biosynthesis; Differential proteomics; Photorespiration; Photosynthetic apparatus; Regulatory mechanisms.

Mixotrophy of Haematococcus pluvialis is a potential strategy for producing astaxanthin. However, this strategy has not been extensively commercialized because the mixotrophic mechanisms by which H. pluvialis overcomes high light stress are unclear. This study analyzed the biochem. compositions and differential proteomics of mixotrophic H. pluvialis under different light conditions. High light exposure substantially increased astaxanthin, carbohydrate, and fatty acid contents. A total of 119 and 81 proteins were significantly up- and down-regulated after two days of high light exposure. These proteins mainly enriched pathways for photosynthetic metabolism, glyoxylate cycle, and biosynthesis of secondary metabolites. This study proposed a regulatory model through which mixotrophic H. pluvialis copes with high light stress. The model includes pathways for modulating photosynthetic apparatus, increasing astaxanthin accumulation by enhancing photorespiration, pentose phosphate and Embden-Meyerhof-Parna pathways, while thickening the cell wall by malate-oxaloacetate shuttle.

Hypertension is a lifestyle-related disease which often leads to serious conditions such as heart disease and cerebral hemorrhage. Angiotensin II (Ang II) plays an important role in regulating cardiovascular homeostasis. Consequently, antagonists that block the interaction of Ang II with its receptors are thought to be effective in the suppression of hypertension. In this study, we searched for plant compounds that had antagonist-like activity toward Ang II receptors. From among 435 plant samples, we found that EtOH extract from the resin of sweet gum Liquidambar styraciflua strongly inhibited Ang II signaling. We isolated benzyl benzoate and benzyl cinnamate from this extract and found that those compounds inhibited the function of Ang II in a dose-dependent manner without cytotoxicity. An in vivo study showed that benzyl benzoate significantly suppressed Ang II-induced hypertension in mice. In addition, we synthesized more than 40 derivatives of benzyl benzoate and found that the meta-Me and 3-methylbenzyl 2′-nitrobenzoate derivatives showed about 10-fold higher activity than benzyl benzoate itself. Thus, benzyl benzoate, its derivatives, and benzyl cinnamate may be useful for reducing hypertension.
