LED 209 conjugated chitosan as a selective antimicrobial and potential anti-adhesion material

Zhou, Zongbao,Chen, Tao,Mei, Naibin,Li, Bing,Xu, Zunkai,Wang, Lei,Wang, Xiaoying,Tang, Shunqing

, p. 653 - 663 (2019)

The rapid emergence of antibiotic-resistant Gram-negative bacteria (GNB) is becoming a global healthcare concern, and it urgently needs novel strategies to match the clinical challenge. In this work, we conjugated chitosan (CS) with LED 209, a highly selective inhibitor of QseC of GNB, to create the novel selective antimicrobial agent CS/LED. The data of FT-IR, NMR and elemental analysis for CS/LED conjugates proved the successful conjugation of CS with LED 209. Interestingly, the fluorescence signal detected in MDR-E. coli of CS/LED-FITC was about 2 times than that of CS-FITC at 3 h. The results shown that compared with CS, CS/LED exhibited higher selective antimicrobial on MDR-E. coli. Moreover, CS/LED exhibited the lower selectivity and cytotoxicity to mammalian cell than CS. Additionally, an unexpected enhancement of anti-adhesion activity against MDR-E. coli was determined by cellulose membrane coating CS/LED. The results demonstrated that CS/LED could reduce the adhesion of bacteria to the cellulose membrane by about 67.8%, while CS only reduced by about 45.3%. The dressings coated with CS/LED possessed the stronger ability to prevent microbial adhesion compared to the CS-coated dressing. Our present work firstly demonstrated that CS/LED had a highly selective activity and anti-adhesion activity against MDR-E. coli, which offered a potent and selective antimicrobial for combating multidrug-resistant GNB infections.

Structures of silver sulfonamides

Bult,Klasen

, p. 284 - 287 (1978)

The structures of silver sulfonamides were found to depend highly on the substituent at the amide nitrogen of the sulfonamide. Silver is coordinated to that nitrogen and the sulfonamide is in the amido form if no substituent is present or if the substituent is a phenyl, acetyl, or 2-pyrimidyl group. If the substituent is a 2-thiazolyl or 2-pyridinyl group, the sulfonamide is in the imido form and silver coordinates to the nitrogen of the substituent. Depending on the number of suitable donor atoms per sulfonamide, the silver compounds are charged or uncharged and the primary amino group may be involved in complexation.

Discovery of N-(3,4-Dimethylphenyl)-4-(4-isobutyrylphenyl)-2,3,3a,4,5,9b-hexahydrofuro[3,2- c]quinoline-8-sulfonamide as a Potent Dual MDM2/XIAP Inhibitor

Wu, Zhongzhi,Gu, Lubing,Zhang, Sicheng,Liu, Tao,Lukka, Pradeep B.,Meibohm, Bernd,Bollinger, John C.,Zhou, Muxiang,Li, Wei

, p. 1930 - 1950 (2021/03/01)

Murine double minute 2 (MDM2) and X-linked inhibitor of apoptosis protein (XIAP) are important cell survival proteins in tumor cells. As a dual MDM2/XIAP inhibitor reported previously, compound MX69 has low potency with an IC50 value of 7.5 μM against an acute lymphoblastic leukemia cell line EU-1. Herein, we report the structural optimization based on the MX69 scaffold, leading to the discovery of a 25-fold more potent analogue 14 (IC50 = 0.3 μM against EU-1). We demonstrate that 14 maintains its mode of action by dual targeting of MDM2 and XIAP through inducing MDM2 protein degradation and inhibiting XIAP mRNA translation, respectively, which resulted in cancer cell growth inhibition and cell death. The results strongly suggest that the scaffold based on 14 is promising for further optimization to develop a new therapeutic agent for leukemia and possibly other cancers where MDM2 and XIAP are dysregulated.

Structure-activity relationships of agonists for the orphan G protein-coupled receptor GPR27

Blavier, Jeremy,Charles, Ma?lle,Hanson, Julien,Kronenberger, Thales,Laschet, Céline,Müller, Christa E.,Pillaiyar, Thanigaimalai,Rosato, Francesca,Wozniak, Monika

, (2021/08/27)

GPR27 belongs, with GPR85 and GPR173, to a small subfamily of three receptors called “Super-Conserved Receptors Expressed in the Brain” (SREB). It has been postulated to participate in key physiological processes such as neuronal plasticity, energy metabolism, and pancreatic β-cell insulin secretion and regulation. Recently, we reported the first selective GPR27 agonist, 2,4-dichloro-N-(4-(N-phenylsulfamoyl)phenyl)benzamide (I, pEC50 6.34, Emax 100%). Here, we describe the synthesis and structure-activity relationships of a series of new derivatives and analogs of I. All products were evaluated for their ability to activate GPR27 in an arrestin recruitment assay. As a result, agonists were identified with a broad range of efficacies including partial and full agonists, showing higher efficacies than the lead compound I. The most potent agonist was 4-chloro-2,5-difluoro-N-(4-(N-phenylsulfamoyl)phenyl)benzamide (7y, pEC50 6.85, Emax 37%), and the agonists with higher efficacies were 4-chloro-2-methyl-N-(4-(N-phenylsulfamoyl)phenyl)benzamide (7p, pEC50 6.04, Emax 123%), and 2-bromo-4-chloro-N-(4-(N-phenylsulfamoyl)phenyl)benzamide (7r, pEC50 5.99, Emax 123%). Docking studies predicted the putative binding site and interactions of agonist 7p with GPR27. Selected potent agonists were found to be soluble and devoid of cellular toxicity within the range of their pharmacological activity. Therefore, they represent important new tools to further characterize the (patho)physiological roles of GPR27.

Comparative study between the anti-P. falciparum activity of triazolopyrimidine, pyrazolopyrimidine and quinoline derivatives and the identification of new PfDHODH inhibitors

Silveira, Flávia F.,de Souza, Juliana O.,Hoelz, Lucas V.B.,Campos, Vinícius R.,Jabor, Valquíria A.P.,Aguiar, Anna C.C.,Nonato, M. Cristina,Albuquerque, Magaly G.,Guido, Rafael V.C.,Boechat, Nubia,Pinheiro, Luiz C.S.

, (2020/11/10)

In this work, we designed and synthesized 35 new triazolopyrimidine, pyrazolopyrimidine and quinoline derivatives as P. falciparum inhibitors (3D7 strain). Thirty compounds exhibited anti-P. falciparum activity, with IC50 values ranging from 0.030 to 9.1 μM. The [1,2,4]triazolo[1,5-a]pyrimidine derivatives were more potent than the pyrazolo[1,5-a]pyrimidine and quinoline analogues. Compounds 20, 21, 23 and 24 were the most potent inhibitors, with IC50 values in the range of 0.030–0.086 μM and were equipotent to chloroquine. In addition, the compounds were selective, showing no cytotoxic activity against the human hepatoma cell line HepG2. All [1,2,4]triazolo[1,5-a]pyrimidine derivatives inhibited PfDHODH activity in the low micromolar to low nanomolar range (IC50 values of 0.08–1.3 μM) and did not show significant inhibition against the HsDHODH homologue (0–30% at 50 μM). Molecular docking studies indicated the binding mode of [1,2,4]triazolo[1,5-a]pyrimidine derivatives to PfDHODH, and the highest interaction affinities for the PfDHODH enzyme were in agreement with the in vitro experimental evaluation. Thus, the most active compounds against P. falciparum parasites 20 (R = CF3, R1 = F; IC50 = 0.086 μM), 21 (R = CF3; R1 = CH3; IC50 = 0.032 μM), 23, (R = CF3, R1 = CF3; IC50 = 0.030 μM) and 24 (R = CF3, 2-naphthyl; IC50 = 0.050 μM) and the most active inhibitor against PfDHODH 19 (R = CF3, R1 = Cl; IC50 = 0.08 μM - PfDHODH) stood out as new lead compounds for antimalarial drug discovery. Their potent in vitro activity against P. falciparum and the selective inhibition of the PfDHODH enzyme strongly suggest that this is the mechanism of action underlying this series of new [1,2,4]triazolo[1,5-a]pyrimidine derivatives.

Sulphonamidic Groups as Electron-Withdrawing Units in Ureido-Based Anion Receptors: Enhanced Anion Complexation versus Deprotonation

?imková, Ludmila,Císa?ová, Ivana,Cu?ínová, Petra,Ludvík, Ji?í,Sykora, Jan,Salvadori, Karolína

, p. 1401 - 1411 (2020/08/05)

A sulphonamidic moiety was utilized as an electron-withdrawing group for enhancement of anion complexation features of urea-based receptors. A series of receptors varying in acidity of sulphonamidic and urea NH groups was synthesized and thoroughly tested. The individual complexation properties reflect deprotonation/complexation equilibrium in a given molecule as a function of the substitution. The receptors containing electron-donating groups in conjugation to the sulphonamidic moiety showed higher association constants towards H2PO4? and carboxylate anions, while those containing electron-withdrawing groups inclined to deprotonation of sulphonamidic NH. The deprotonation issue can be avoided by alkylation at the early step of receptor synthesis or it can be utilized for insertion of suitable groups that enable its anchoring on various substrates to form more elaborated receptor structures.

Ge, Shushan,Guo, Wenjie,Hu, Yue,Lai, Yisheng,Li, Yuezhen,Liu, Wen,Ma, Xuewei,Wang, Fang,Wang, Yan,Xu, Qiang,Zheng, Yingbo,Zhong, Haiqing,Zou, Yi

Indoleamine 2,3-dioxygenase 1 (IDO1) as a key rate-limiting enzyme in the kynurenine pathway of tryptophan metabolism plays an important role in tumour immune escape. Herein, a variety of secondary sulphonamides were synthesised and evaluated in the HeLa cell-based IDO1/kynurenine assay, leading to the identification of new IDO1 inhibitors. Among them, compounds 5d, 5l and 8g exhibited the strongest inhibitory effect with significantly improved activity over the hit compound BS-1. The in vitro results showed that these compounds could restore the T cell proliferation and inhibit the differentiation of na?ve CD4+ T cell into highly immunosuppressive FoxP3+ regulatory T (Treg) cell without affecting the viability of HeLa cells and the expression of IDO1 protein. Importantly, the pharmacodynamic assay showed that compound 5d possessed potent antitumour effect in both CT26 and B16F1 tumours bearing immunocompetent mice but not in immunodeficient mice. Functionally, subsequent experiments demonstrated that compound 5d could effectively inhibit tumour cell proliferation, induce apoptosis, up-regulate the expression of IFN-γ and granzyme B, and suppress FoxP3+ Treg cell differentiation, thereby activate the immune system. Thus, compound 5d could be a potential and efficacious agent for further evaluation.

Chen, Kai,Chen, Wei,Han, Bing,Chen, Wanzhi,Liu, Miaochang,Wu, Huayue

supporting information, p. 1841 - 1845 (2020/03/04)

A one-pot three-component reaction involving nitroarenes, (hetero)arylboronic acids, and potassium pyrosulfite leading to sulfonamides was described. A broad range of sulfonamides bearing different reactive functional groups were obtained in good to excellent yields through sequential C-S and S-N coupling that does not require metal catalysts.

Synthesis, structural, biological and in silico studies of new 5-arylidene-4-thiazolidinone derivatives as possible anticancer, antimicrobial and antitubercular agents

Sunil Kumar,Kudva, Jyothi,Bharath,Ananda,Sadashiva, Rajitha,Madan Kumar,Revanasiddappa,Kumar, Vasantha,Rekha,Naral, Damodara

, p. 1597 - 1610 (2019/01/21)

A new series of halogenated 4-thiazolidinone derivatives bearing the sulfonamide moiety was synthesized and characterized via FT-IR, 1H NMR, 13C NMR, HRMS and single crystal X-ray analysis. The newly synthesized target compounds were screened for their in vitro cytotoxicity on the HepG2 and MDA-MB-231 cell lines, and antimicrobial and antitubercular activity. The compounds showed promising anticancer activity towards the MDA-MB-231 cell line, and the trichloro derivatives with p-chloro substitution (6i) and p-hydroxy substitution (7e) exhibited excellent anticancer activity. Compounds 6b and 7c were observed to be moderate antimicrobial agents. The seven most potent anticancer agents were further studied for their antitubercular activity against an M. tuberculosis strain and it was found that compound 7e showed significant antitubercular activity. The potent candidates were also tested for hemolysis activity against human RBC cells and were found to be non-toxic. The mode of action for the observed anticancer activity was further supported by molecular docking studies of the potent compounds against the enzyme Aurora kinase (PDB ID: 4ZTR). Molecular dynamics (MD) simulations were further performed to study the stability of the ligand-protein complex.

Effect of photodynamic antibacterial chemotherapy combined with antibiotics on Gram-positive and gram-negative bacteria

Ilizirov, Yana,Formanovsky, Andrei,Mikhura, Irina,Paitan, Yossi,Nakonechny, Faina,Nisnevitch, Marina

, (2018/12/11)

The well-known and rapidly growing phenomenon of bacterial resistance to antibiotics is caused by uncontrolled, excessive and inappropriate use of antibiotics. One of alternatives to antibiotics is Photodynamic Antibacterial Chemotherapy (PACT). In the present study, the effect of PACT using a photosensitizer Rose Bengal alone and in combination with antibiotics including methicillin and derivatives of sulfanilamide synthesized by us was tested against antibiotic-sensitive and antibiotic-resistant clinical isolates of Gram-positive S. aureus and Gram-negative P. aeruginosa. Antibiotic-sensitive and resistant strains of P. aeruginosa were eradicated by Rose Bengal under illumination and by sulfanilamide but were not inhibited by new sulfanilamide derivatives. No increase in sensitivity of P. aeruginosa cells to sulfanilamide was observed upon a combination of Rose Bengal and sulfanilamide under illumination. All tested S. aureus strains (MSSA and MRSA) were effectively inhibited by PACT. When treated with sub-MIC concentrations of Rose Bengal under illumination, the minimum inhibitory concentrations (MIC) of methicillin decreased significantly for MSSA and MRSA strains. In some cases, antibiotic sensitivity of resistant strains can be restored by combining antibiotics with PACT.
