Abstract
One of the chief pathways to regulate p53 levels is MDM2 protein, which negatively controls p53 by direct inhibition. Many cancers overproduce MDM2 protein to interrupt p53 functions. Therefore, impeding MDM2's binding to p53 can reactivate p53 in tumor cells may suggest an effective approach for tumor therapy. Here, some Monastrol derivatives were designed in silico as MDM2 inhibitors, and their initial cytotoxicity was evaluated in vitro on MFC-7 and MDA-MB-231 cells. A small library of Monastrol derivatives was created, and virtual screening (VS) was performed on them. The first-ranked compound, which was extracted from VS, and the other six compounds 5a-5f were selected to carry out the single-docking and docking with explicit waters. The compound with the best average results was then subjected to molecular dynamic (MD) simulation. Compounds 5a-5f were chemically synthesized and evaluated in vitro for their initial cytotoxicity on MFC-7 and MDA-MB-231 cells by MTT assay. The best compound was compound 5d with ΔGave = -10.35 kcal/mol. MD simulation revealed a median potency in comparison with Nutlin-3a. The MTT assay confirmed the docking and MD experiments. 5d has an IC50 of 60.09 μM on MCF-7 cells. We attempted to use Monastrol scaffold as a potent inhibitor of MDM2 rather than an Eg5 inhibitor using in silico modification. The results obtained from the in silico and in vitro evaluations were noteworthy and warranted much more effort in the future.

Abstract
The increase in bacterial resistance to antimicrobials has led to high morbidity and mortality rates, posing a major public health problem, requiring the discovery of novel antimicrobial substances. The biological samples were identified as the Gram-negative bacilli Acinetobacter baumannii, Escherichia coli, Enterobacter cloacae, Klebsiella pneumoniae, Morganella morgannii, Pseudomonas aeruginosa and Serratia marcescens and the Gram-positive cocci Enterococcus faecium, and Staphylococcus aureus, all of them resistant to at least three classes of antimicrobials. The antibacterial activity of the compounds was checked in vitro by determining the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) by the broth microdilution method and plating in brain heart infusion (BHI) agar, respectively. The chemical characterization of the compounds was performed by measuring the melting point and gas chromatography coupled with mass spectrometry (GC–MS) on a Shimadzu GC–MS-QP system 2010SE. Synthetic compounds showed antimicrobial activity against Gram-positive cocci at MIC concentrations 0.16–80 μg/ml and Gram-negative bacilli at MIC concentrations 23.2–80 μg/ml. Enterococcus faecium and S. aureus had the best MIC values. The results of the cytotoxicity test indicated that the synthetic compounds showed no significant difference in three concentrations tested (5, 20, and 80 μg/ml), allowing cell viability not different from that assigned to the control, without the tested compounds. In this context, the development of DHPM derivatives brings an alternative and perspective on effectiveness of drugs as potential future antimicrobial agents.

[PMID: 34126912 DOI: 10.2174/1871520621666210612043812] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2020] [Revised: 04/29/2021] [Accepted: 05/02/2021] [Indexed: 11/22/2022]
Abstract
BACKGROUND Pyrimidine-5-carbonitrile had a broad spectrum of biological activities such as antiviral, antioxidant and anticancer activity. Among similar compounds, monastrol being the most prominent due to cell-permeant inhibitor of mitosis therefore, we investigated the new Pyrimidine-5-carbonitrile as a cytotoxic agent for p53 pathway. OBJECTIVE Several new benzyloxyphenyl pyrimidine-5-carbonitrile derivatives were designed, synthesized, characterized, and their cytotoxicity was evaluated. The most active compounds were tested for their activity against p53 as a mechanistic target for antiproliferative action. METHOD The key intermediate tetrahydropyrimidine-5-carbonitrile derivative 4 was prepared by a multicomponent reaction (MCR) of Biginelli type. S-alkylation of the key intermediate with the required alkyl or aralkyl halides or refluxing 4 with POCl3 followed by an amino acid yielded the target compounds. The cytotoxicity of 5c-e, 7a-c, 9, 10a, b and 11 was evaluated using A549 cell line of human lung adenocarcinoma, HepG2 liver cell line, and MDA-MB-231 cell line of breast cancer using the MTT assay. The transcription effects of 7a, 7c, and 11 on the p53 were assessed and compared with the reference doxorubicin. RESULTS Compounds 7a, 7c, and 11 have the highest cytotoxic effect when applied to most cancer cells. The tested compounds with 5-FU showed a significant increase in the anticancer activity more than 5-FU alone. Compounds 7a, 7c, and 11 increased the level of active caspase 3 by 4-6-fold, compared to untreated control cells in human liver cancer cell line (HepG2). Compounds 7a, 7c, and 11 increase the levels of caspase 8 and 9, indicating activation of both intrinsic and extrinsic pathways and showed potent induction of Bax, down-regulation of Bcl-2 protein levels and over-expression of Cytochrome C levels in HepG2 cell lines. Compound 11 exhibited cell cycle arrest at the Pre-G1 and G2/M phases in the cell cycle analysis of HepG2 cell line. The results revealed an increase of 12.40-19.10 in p53 level compared to the test cells and that p53 protein level of 7a, 7c, and 11 was significantly inductive (636, 861 and 987 pg/mL, respectively) in relation to doxorubicin (1263 pg/mL). CONCLUSION Pyrimidine-5-carbonitrile derivatives have potent apoptotic and antiproliferative properties.

Abstract
A large number of convincing evidences has revealed the correlation of the pathogeny of diseases with the oxidative damages of DNA, protein, biomembrane, and other biological species, while supplementation of antioxidants is demonstrated to be a promising way to avoid, at least, rectify the unbalance redox status in vivo. Although many endeavors have focused on synthesis of antioxidants, a main hurdle still hinders the wide usages of synthetic antioxidants because of low bioavailability and potential cytotoxicity. The search for antioxidants with multiple functional groups being recognized by different receptors becomes a much sought by researchers, and multicomponent reactions (MCRs) provide with powerful tools for the construction of multifunctional antioxidants. Presented herein is a personal account on the application of MCRs for the synthesis of multifunctional antioxidants, while radical-induced oxidation of DNA acts as the experimental system for evaluating antioxidative effect. Concretely, the Biginelli three-component reaction (3CR) affords such a dihydropyrimidine scaffold that the tautomerization between C=S and C-SH leads to antioxidative effect. The Povarov 3CR is able to integrate multiple antioxidative groups, i. e., ferrocenyl and -N(CH3 )2 , into a quinoline scaffold, while the Groebke 3CR provides with imidazo[1,2-a]pyridine skeleton for inhibiting DNA oxidation. Additionally, the Knoevenagel-related MCRs also become efficient strategies for achieving radical-scavengers. On the other hand, the Ugi 4CR and Passerini 3CR result in the dipeptide and α-acyloxycarboxamide, respectively, with the benefit for the integration of antioxidative features by aliphatic chains. Therefore, MCRs have emerged as efficient tools for integrating multiple antioxidative features into one molecule in order to meet with complicated requirements from various biological surroundings.

Abstract
3,4-dihydropyrimidin-2(1H)-one compounds (DHPMs) possess extensive biological activities and are mainly prepared via Biginelli reaction and N-alkylation. In the present study, selective alkylation of N¹ was investigated by using tetrabutylammonium hydroxide. In vitro cytotoxicity study on all synthesized compounds demonstrated that introduction of the aryl chain in the R³ as well as the low electron-donating group in the R¹ of DHPMs contributed to the anti-proliferative potency. A larger value of the partition coefficient (Log P) and suitable polar surface area (PSA) values were both found to be important in order to maintain the antitumor activity. The results from in vivo study indicated the great potential of compound 3d to serve as a lead compound for novel anti-tumor drugs to treat glioma. Pharmacophore study regarding the structure-activity relations of DHPMs were also conducted. Our results here could provide a guide for the design of novel bioactive 3,4-dihydropyrimidin-2(1H)-one compounds.

Abstract
Over the years, with the instrumental analysis evolution, the relationships between the carried-out results with the data of theoretical analysis in silico and the Hammett's parameters have been reported. They have been very useful for chemical characterization of small organic molecules. Thus, this work aims at showing the feasibility and limitations for Hammett's and density functional theory applications in electrospray ionization-collision-induced dissociation (ESI-CID) fragmentation provision. For this, 13 dihydropyrimidinones para, meta, and orto monosubstituted were studied using ESI and CID in positive mode. As a result, it was observed that the main fragmentation includes the isocyanate and ethanol loses at low energy. Nevertheless, at higher energies, radical ions formed by McLafferty rearrangement were observed. The Hammett plots were correlated fragmentation profiles, showing good linearity for the [M + H]+ , which does not occur to radical ions and carbocation's. These tendencies had demonstrated that the stability of protonate and activation energy of secondary ions changes with the pKa. The density functional theory studies indicated that, both nitrogen atoms in the dihydropyrimidinone's prototypes are capable of being protonated. However, the activation energy of fragmentation products is not changed. Therefore, this work has shown information, which can be useful to understand tandem mass spectrometry in ESI-CID conditions for small organic molecules series. This is the first step for normalization of fragmentation pathway.

Abstract
Dihydropyrimidinones are heterocycles with a pyrimidine moiety in the ring nucleus, which, in recent decades, have aroused interest in medicinal chemistry due to alleged versatile biological activity. In this systematic review, we describe the currently published activities of dihydropyrimidinone derivatives. Between 1990 and December 31st, 2016, 115 articles outlined biological activities or toxicity of DHPM derivatives, 12 of those involved in vivo experiments. The main activities associated with this class of compounds are antitumoral (43 articles), anti-inflammatory (12 articles), antibacterial (20 articles) and calcium channel antagonism/inhibition (14 articles). Antitumoral activity is the main biological property evaluated, since the main representative compound of this class (monastrol) is a known Eg5 kinesin inhibitor. This review depicts a variety of other pharmacological activities associated with DHPM derivatives, but the main findings are essentially in vitro characteristics of the substances. This review presents the current state of the art of DHPM biological activities and demonstrates that there is still a need for further in vivo studies to better delineate the pharmacological potential of this class of substances.

Bilal S, Khan AL, Waqas M, Shahzad R, Kim ID, Lee IJ, Shin DH. Biochemical Constituents and in Vitro Antioxidant and Anticholinesterase Potential of Seeds from Native Korean Persimmon Genotypes. Molecules 2016; 21:E893. [PMID: 27399664 PMCID: PMC6274387 DOI: 10.3390/molecules21070893] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2016] [Revised: 06/30/2016] [Accepted: 07/01/2016] [Indexed: 01/16/2023] Open
Abstract
In the current study, the functional and biochemical potential of the seeds of four persimmon cultivars (PC1, PC2, PC3 and PC4) and their role against oxidative stress and acetylcholinesterase (AChE) inhibition were evaluated. In terms of biochemical compositions, free amino acids, fatty acids and organic acids analysis was performed. The free amino acids ranged from 2617.31 (PC2) to 3773.01 μg∙g(-1) dry weight (PC4). Oleic acid and linoleic acid were the principal fatty acids, which were significantly higher in PC4 and PC1, respectively. PC4 presented the highest amount of organic acid content (4212 mg∙kg(-1)), whereas PC2 presented the lowest (2498 mg∙kg(-1)). PC2 contained higher total phenolic content and flavonoid content, whereas PC3 had the lowest amount as compared to other cultivars. The in vitro DPPH, ABTS and superoxide anion radicals scavenging activity increased in a dose-dependent manner, whereas PC2 showed significantly higher scavenging activities as compared to PC1, PC2 and PC4 types. In the case of AChE inhibition, PC4 showed a moderate activity (67.34% ± 1.8%). In conclusion, the current findings reveal that the studied persimmon seeds cultivars are a source of bioactive natural antioxidants and AChE inhibitors. Such natural products could be employed in pharmaceutical and food industries, whilst can also be considered for the treatment of neurodegenerative diseases such as Alzheimer's.

Antifungal susceptibility, exoenzyme production and cytotoxicity of novel oximes against Candida. Mycopathologia 2013; 176:201-10.

Abstract
Novel oximes were synthesized, their in vitro antifungal activity against Candida was evaluated and their cytotoxicity was determined. The procedure used for the synthesis of the oximes is aligned with the current green chemistry trend; water is employed as the solvent in this reaction. The minimum inhibitory and minimum fungicidal concentrations of the oximes were evaluated using the CLSI M27-A3 method. The influence of these compounds on the inhibition of the production of hydrolytic enzymes, phospholipase and proteinase by Candida was also investigated. The compounds showed a good ability to inhibit phospholipase, with a 50 % reduction in most cases. However, the tested compounds did not affect proteinase. The current results showed a substantial reduction in the phospholipase production, which suggests that compounds of this class may interfere with host infection and disease progression. The oximes examined showed lower fungicidal activities than fluconazole but interfered significantly with the expression of phospholipase. Some of the oximes included in this study could be a suitable matrix for the development of novel antifungal compounds.

Abstract
In current study, we report efficient and clean procedure for preparing mycosporine-like amino acids (MMAs) analogs and evaluate their ultraviolet absorbance properties and antioxidant activities. The ultraviolet radiation absorbance patterns of the compounds were recorded and then used to define their molar absorptivities. The antioxidant activities were assessed using 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging and superoxide radical scavenging assays. Eight of nine compounds showed good activity against superoxide radicals, as only one of the analogs exhibited a measurable IC50 in the DPPH assay.
