Abstract
Gain-of-function (GoF) variants in KCNT1 channels cause severe, drug-resistant forms of epilepsy. Quinidine is a known KCNT1 blocker, but its clinical use is limited due to severe drawbacks. To identify novel KCNT1 blockers, a homology model of human KCNT1 was built and used to screen an in-house library of compounds. Among the 20 molecules selected, five (CPK4, 13, 16, 18, and 20) showed strong KCNT1-blocking ability in an in vitro fluorescence-based assay. Patch-clamp experiments confirmed a higher KCNT1-blocking potency of these compounds when compared to quinidine, and their selectivity for KCNT1 over hERG and Kv7.2 channels. Among identified molecules, CPK20 displayed the highest metabolic stability; this compound also blocked KCNT2 currents, although with a lower potency, and counteracted GoF effects prompted by 2 recurrent epilepsy-causing KCNT1 variants (G288S and A934T). The present results provide solid rational basis for future design of novel compounds to counteract KCNT1-related neurological disorders.

Abstract
In pursuit of discovering novel scaffolds that demonstrate potential inhibitory activity against p38α MAPK and possess strong antitumor effects, we herein report the design and synthesis of new series of 17 final target 5-(2,6-dichlorophenyl)-3-oxo-2,3-dihydro-5H-thiazolo[3,2-a]pyrimidine-7-carboxylic acids (4-20). Chemical characterization of the compounds was performed using FT-IR, NMR, elemental analyses and mass spectra of some representative examples. With many compounds showing potential inhibitory activity against p38α MAPK, two derivatives, 8 and 9, demonstrated the highest activity (>70 % inhibition) among the series. Derivative 9 displayed IC50 value nearly 2.5 folds more potent than 8. As anticipated, they both showed explicit interactions inside the kinase active site with the key binding amino acid residues. Screening both compounds for cytotoxic effects, they exhibited strong antitumor activities against lung (A549), breast (MCF-7 and MDA MB-231), colon (HCT-116) and liver (Hep-G2) cancers more potent than reference 5-FU. Their noticeable strong antitumor activity pointed out to the possibility of an augmented DNA binding mechanism of antitumor action besides their kinase inhibition. Both 8 and 9 exhibited strong ctDNA damaging effects in nanomolar range. Further mechanistic antitumor studies revealed ability of compounds 8 and 9 to arrest cell cycle in MCF-7 cells at S phase, while in HCT-116 treated cells at G0-G1 and G2/M phases. They also displayed apoptotic induction effects in both MCF-7 and HCT-116 with total cell deaths more than control untreated cells in reference to 5-FU. Finally, the compounds were tested for their anti-migratory potential utilizing wound healing assay. They induced a significant decrease in wound closure percentage after 24 h treatment in the examined cancer cells when compared to untreated control MCF-7 and HCT-116 cells better than 5-FU. In silico computation of physicochemical parameters revealed the drug-like properties of 8 and 9 with no violation to Lipinski's rule of five as well as their tolerable ADMET parameters, thus suggesting their utilization as potential future drug leads amenable for further optimization and development.

Abstract
Scar formation is a process that occurs due to increased collagen deposition and uncontrolled inflammation. Previous studies have demonstrated that Pirfenidone (Pf), an FDA approved anti-inflammatory and antifibrotic drug can reduce inflammation in vivo as well as regulate activation of LPS-stimulated neutrophils. However, the molecular level mechanism of Pf's action is not well understood. Here, we used neural networks to identify new targets and molecular modeling methods to investigate the Pf's action pathways at the molecular level that are related to its ability to reduce both the inflammatory and remodeling phases of the wound healing process. Out of all the potential targets identified, both molecular docking and molecular dynamics results suggest that Pf has a noteworthy binding preference towards the active conformation of the p38 mitogen activated protein kinase-14 (MAPK14) and it is potentially a type I inhibitor-like molecule. In addition to p38 MAPK (MAPK14), additional potential targets of Pf include AKT1, MAP3K4, MAP2K3, MAP2K6, MSK2, MAP2K2, ERK1, ERK2, and PDK1. We conclude that several proteins/kinases, rather than a single target, are involved in Pf's wound healing ability to regulate signaling, inflammation, and proliferation.

Abstract
The recent increase of bioactivity data freely available to the scientific community and stored as activity data points in chemogenomic repositories provides a huge amount of ready-to-use information to support the development of predictive models. However, the benefits provided by the availability of such a vast amount of accessible information are strongly counteracted by the lack of uniformity and consistency of data from multiple sources, requiring a process of integration and harmonization. While different automated pipelines for processing and assessing chemical data have emerged in the last years, the curation of bioactivity data points is a less investigated topic, with useful concepts provided but no tangible tools available. In this context, the present work represents a first step toward the filling of this gap, by providing a tool to meet the needs of end-user in building proprietary high-quality data sets for further studies. Specifically, we herein describe Q-raKtion, a systematic, semiautomated, flexible, and, above all, customizable KNIME workflow that effectively aggregates information on biological activities of compounds retrieved by two of the most comprehensive and widely used repositories, PubChem and ChEMBL.

Abstract
Acute myeloid leukemia (AML) is a heterogeneous hematopoietic malignancy whose prognosis is globally poor. In more than 60% of AML patients, the PI3K/AKTs/mTOR signaling pathway is aberrantly activated because of oncogenic driver alterations and further enhanced by chemotherapy as a mechanism of drug resistance. Against this backdrop, very recently we have started a multidisciplinary research project focused on AKT1 as a pharmacological target to identify novel anti-AML agents. Indeed, the serendipitous finding of the in-house compound T187 as an AKT1 inhibitor has paved the way to the rational identification of new active small molecules, among which T126 has emerged as the most interesting compound with IC50 = 1.99 ± 0.11 μM, ligand efficiency of 0.35, and a clear effect at low micromolar concentrations on growth inhibition and induction of apoptosis in AML cells. The collected results together with preliminary SAR data strongly indicate that the 5,6,7,8-tetrahydrobenzo[4,5]thieno[2,3-d]pyrimidin-4(3H)-one derivative T126 is worthy of future biological experiments and medicinal chemistry efforts aimed at developing a novel chemical class of AKT1 inhibitors as anti-AML agents.

Abstract
Transient receptor potential melastatin type 8 (TRPM8) is a target for the treatment of different physio-pathological processes. While TRPM8 antagonists are reported as potential drugs for pain, cancer, and inflammation, to date only a limited number of chemotypes have been investigated and thus a limited number of compounds have reached clinical trials. Hence there is high value in searching for new TRPM8 antagonistic to broaden clues to structure-activity relationships, improve pharmacological properties and explore underlying molecular mechanisms. To address this, the EDASA Scientific in-house molecular library has been screened in silico, leading to identifying twenty-one potentially antagonist compounds of TRPM8. Calcium fluorometric assays were used to validate the in-silico hypothesis and assess compound selectivity. Four compounds were identified as selective TRPM8 antagonists, of which two were dual-acting TRPM8/TRPV1 modulators. The most potent TRPM8 antagonists (BB 0322703 and BB 0322720) underwent molecular modelling studies to highlight key structural features responsible for drug-protein interaction. The two compounds were also investigated by patch-clamp assays, confirming low micromolar potencies. The most potent compound (BB 0322703, IC50 1.25 ± 0.26 μM) was then profiled in vivo in a cold allodinya model, showing pharmacological efficacy at 30 μM dose. The new chemotypes identified showed remarkable pharmacological properties paving the way to further investigations for drug discovery and pharmacological purposes.

Abstract
This work describes the rational discovery of novel chemotypes of p38α MAPK inhibitors using a funnel approach consisting of several computer-aided drug discovery methods and biological experiments. Among the identified hits, four compounds belonging to different chemical families showed IC50 values lower than 10 μM. In particular, the 1,4-benzodioxane derivative 5 turned out to be a potent and efficient p38α MAPK inhibitor having IC50 = 0.07 μM, and LEexp and LipE values of 0.38 and 4.8, respectively; noteworthy, the compound had also a promising kinase selectivity profile and the capability to suppress p38α MAPK effects in human immune cells. Overall, the collected findings highlight that the applied strategy has been successful in generating chemical novelty in the inhibitor kinase field, providing suitable chemical candidates for further inhibitor optimization.

Abstract
A series of variously functionalized selenium-containing compounds were purposely synthesized and evaluated against a panel of cancer cell lines. Most of the compounds showed an interesting cytotoxicity profile with compound 5 showing a potent activity on MCF7 cells. The ethyl amino derivative 5 acts synergistically with cis-platin and inhibits the GST enzyme with a potency that well correlates with the cytotoxicity observed in MCF7 cells. A computational analysis suggests a possible binding mode on the GST enzyme. As the main outcome of the present study, the ethyl amino derivative 5 emerged as a valid lead compound for further, future developments.

Abstract
Nucleocapsid protein 7 (NCp7) represents a viable target not yet reached by the currently available antiretrovirals. It is a small and highly basic protein, which is essential for multiple stages of the viral replicative cycle, with its structure preserved in all viral strains, including clinical isolates. NCp7 can be inhibited covalently, noncovalently and by shielding the nucleic acid (NA) substrates of its chaperone activity. Although covalent NCp7 inhibitors have already been detailed in the first part of this review series, the focus here is based on noncovalent and NA-binder inhibitors and on the analysis of the NCp7 3D structure to deliver fruitful insights for future drug design strategies.

Dilodendron bipinnatum Radlk. inhibits pro-inflammatory mediators through the induction of MKP-1 and the down-regulation of MAPKp38/JNK/NF-κB pathways and COX-2 in LPS-activated RAW 264.7 cells. JOURNAL OF ETHNOPHARMACOLOGY 2017; 202:127-137. [PMID: 28238828 DOI: 10.1016/j.jep.2017.02.026] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/14/2016] [Revised: 02/13/2017] [Accepted: 02/14/2017] [Indexed: 06/06/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The stem bark of Dilodendron bipinnatum Radlk. (Sapindaceae), a tree native to Pantanal of Mato Grosso, Brazil, popularly known as "mulher-pobre" (poor woman), has been historically used by the locals, after decoction and maceration, for the treatment of inflammatory conditions. We have recently shown that these preparations indeed possess anti-inflammatory properties, which are mediated by the inhibition of cell migration and the modulation of Th1 and Th2 cytokines. The NO pathway was not affected. AIM OF THE PRESENT STUDY The aim of the present study was to further investigate the mechanisms responsible for the anti-inflammatory properties of the hydroethanolic extract of the stem bark of Dilodendron bipinnatum (HEDb). MATERIALS AND METHODS HEDb was obtained by maceration of the stem bark of D. bipinnatum as previously described. The corresponding effects on a macrophage-like cell line, RAW 264.7, were investigated. The apoptosis of RAW 264.7 upon treatment with LPS, HEDb and N-acetyl-L-cysteine (NAC) was assessed by flow cytometry, using an Annexin V-PE kit. The production of inflammatory cytokines (TNF-α, IL-1β and IL-10) and PGE2 were evaluated by ELISA, after cell challenge with LPS. The intracellular redox state and changes in mitochondrial membrane potential were also assessed by flow cytometry, using DCFH-DA and JC-1 as probes. The protein expression levels of MAPK p-p38, p-ERK, p-JNK, MKP-1 and COX-2 were analysed by western blotting. Nuclear translocation of NF-қB was assessed by immunofluorescence microscopy. The quantified results are presented as a nuclear:cytoplasmic ratio. RESULTS LPS, HEDb and NAC did not appear to decrease the number of viable cells in comparison to control treatment. HEDb attenuated the production of pro-inflammatory cytokines (IL-1β and TNF-α) and PGE2 induced by LPS but did not affect IL-10. The production of ROS was also inhibited by HEDb (1, 5 or 20µg/mL), even at the lowest concentration; at 20µg/mL, HEDb was more effective than NAC, which was used as a positive control (74.1% and 66.2% inhibition of LPS's effect, respectively). LPS induced an increase in ΔΨm (19.2%, p<0.001), while HEDb inhibited the change in ΔΨm (7.7% at 20µg/mL, p<0.001). The results of western blotting showed that HEDb inhibited the expression of MAPK p-p38, p-JNK and COX-2, while the expression of MKP-1 was increased. p-ERK was not affected. LPS promoted the nuclear translocation of NF-қB p65 (67%, p<0.01) in RAW 264.7 cells, in comparison to baseline (33%). Pre-treatment with HEDb inhibited this translocation of NF-κB p65 (58% at 20µg/mL, p<0.001). CONCLUSION HEDb has a potent anti-inflammatory activity and acts on multiple targets and biological pathways of potential therapeutic relevance.

Synthesis and molecular docking studies of new furochromone derivatives as p38α MAPK inhibitors targeting human breast cancer MCF-7 cells. Bioorg Med Chem 2017; 25:2423-2436. [PMID: 28291685 DOI: 10.1016/j.bmc.2017.02.065] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2017] [Accepted: 02/27/2017] [Indexed: 12/12/2022]
Abstract
Based on the reported high expression of p38α MAP kinase in invasive breast cancers and the activity of different functionalized chromone derivatives as p38α inhibitors, a new set of 4,9-dimethoxy/4-methoxy-7-methyl-5-oxo-5H-furo[3,2-g]chromone derivatives were efficiently synthesized aiming to introduce new p38α MAP kinase suppressors as new anti-breast cancer tools. Using GOLD program, molecular docking study of the target compounds into p38α MAP kinase binding pocket was performed to highlight their scores, mode of binding and the important interactions to the amino acid residues of the enzyme. MTT assay investigated that fifteen target compounds produced marked cytotoxic potency higher than that obtained by Doxorubicin against MCF-7 cancer cells of IC50 values ranging from 0.007 to 0.17μM vs IC50; 0.62μM of doxorubicin. Eleven selected compounds were evaluated for their inhibitory potency against p38α MAPK kinase. The derivatives IVa, Va,b, VIa, IXb and XIIIa represented significant activity (IC50; 0.19-0.67μM) comparing to the reference drug SB203580 (IC50; 0.50μM). In virtue of its promising cytotoxic and p38α MAP kinase inhibition potency, the furochromone derivative IXb was selected as a representative example to investigate its mechanistic effects on cell cycle progression and induction of apoptosis in MCF-7 cell lines. The results showed that the compound IXb induced cell cycle cessation at G2/M phase preventing its mitotic cycle, alongside its noteworthy activation of caspases-9 and -3 which might mediate the apoptosis of MCF-7 cells.
