1,3,4-Thiadiazolium-2-aminide, which is a class of mesoionic compounds, were tested against promastigote and amastigote forms of Leishmania amazonensis. Parasites were assayed with or without the drugs in axenic media, using pentamidine isethionate as a reference drug. The very promising results showed us the most active compounds were the 4′- and 3′-methoxy derivatives against promastigote forms, while the highest activity against the amastigote forms was obtained with the 4′-fluor and 3′-bromo derivatives.
Role of phenoxy radicals in PCDD/F formation
Sidhu, Sukh,Edwards, Phil
, p. 531 - 541 (2002)
In this work, the role of phenoxy radicals in polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/F) formation was investigated by studying the slow oxidation of 2-chlorophenol (2-CP) and 2-chloroanisole (2-CA) at a gas-phase concentration of 4 ppm (～2.1 × 104 μg/m3) over a temperature range of 400-800°C. Residence times were maintained at 2.0 ± 0.10 s. PCDD/F reaction products were dibenzofuran, dibenzo-p-dioxin, 4-chlorodibenzofuran, 1-chlorodibenzo-p-dioxin, 4,6-dichlorodibenzofuran, and 1,6-dichlorodibenzo-p-dioxin (1,6-DCDD). Major products observed in these experiments were 2,6-dichlorophenol, 3-phenyl-2-propenal, 1-indanone, 1,3-isobenzofurandione, and 3-phenyl-2-propenoyl chloride. The 2-CP and 2-CA experiments, along with the variable concentration 2-CA experiments, showed that the concentration of radicals present in the oxidation system has a significant effect on the PCDD/F product distribution and ultimately the PCDD/PCDF ratio. Also, the observation of dichlorinated phenoxy phenol and dichlorinated dihydroxybiphenyl, the proposed intermediate species in the radical-radical mechanism, suggests that radical-radical mechanism dominates gas-phase PCDD/F formation. This information will be helpful in constructing a detailed kinetic mechanism of PCDD/F formation/destruction in combustor postcombustion zone.

Novel 4-(4-substituted amidobenzyl)furan-2(5H)-one derivatives as topoisomerase I inhibitors
Peng, Cheng-Kang,Zeng, Ting,Xu, Xing-Jun,Chang, Yi-Qun,Hou, Wen,Lu, Kuo,Lin, Hui,Sun, Ping-Hua,Lin, Jing,Chen, Wei-Min
, p. 187 - 199 (2017)
In this study, two series of novel 4-(4-substituted amidobenzyl)furan-2(5H)-one derivatives containing an α,β-unsaturated lactone fragment were synthesized and screened for Topo I inhibition and antitumor activity. The topoisomerase I inhibitory activities and cytotoxicities against three human cancer cell lines (MCF-7,Hela,A549) were evaluated. The results revealed that series 2, compounds bearing an exocyclic double bond on the furanone ring, generally showed more potent activity than series 1, compounds lacking an exocyclic double bond. Several compounds of series 2 possess significant Topo I inhibitory activity and potent antiproliferative activity against cancer cell lines. Further mechanism studies of the most active compound of series 2 (B-15) indicated that synthetic compounds can not only stabilize the drug-enzyme-DNA covalent ternary complex as well as camptothecin, but also interfere with the binding between Topo I and DNA. The binding patterns of these compounds with Topo I and structure-activity relationships are discussed.

The development of novel neuroprotection agents is of great significance for the treatment of ischemic stroke. In this study, a series of compounds comprising 2,2-dimethylbenzopyran groups and cinnamic acid groups have been synthesized. Preferential combination principles and bioisostere that improved the neuroprotective effect of the compounds were identified for this series via biological activity assay in vitro. Meanwhile, a functional reversal group of the acrylamide amide resulted in the most active compounds. Among them, BN-07 significantly improved the morphology of neurons and obviously increased cell survival rate of primary neurons induced by oxygen glucose deprivation (OGD), superior to clinically used anti-ischemic stroke drug edaravone (Eda). Overall, our findings may provide an alternative strategy for the design of novel anti-ischemic stroke agents with more potency than Eda.

Volume of Association of Charge-Transfer Interaction of 1-Methyl-3-(carbomethoxy)pyridinium Iodide and Sodium 8-Chlorotheophyllinate in Aqueous Solution
Williams, R. Kenneth
, p. 93 - 95 (1984)
Values have been obtained for the association constant for the interaction of sodium 8-chlorotheophyllinate with 1-methyl-3-(carbomethoxy)pyridinium iodide in aqueous solution at pH 7.0, I = 0.20, at various temperatures and pressures.From these data the apparent volume change on association is estimated to be Δ = -6.5 (+/-0.5) cm3mol-1 at 25 deg C.Values for the compressibility increment were obtained within the range of ΔK = (1.6-2.0) x 1E-9 Pa-1.Values were also obtained for the association constant of sodium 8-chlorotheophyllinate with the methyl ester of trans-cinnamic acid in a methanol and water mixture at 1-atm pressure.The results are interpreted in terms of the volume change to be expected on association due to ion pairing, and the approach of aromatic rings in water.

Saber, Aziza,Driowya, Mohsine,Alaoui, Soukaina,Marzag, Hamid,Demange, Luc,álvarez, Eleuterio,Benhida, Rachid,Bougrin, Khalid
, p. 31 - 40 (2016)
Novel isoxazoline and pyrazoline derivatives of N-substituted saccharin were synthesized in good yields by 1,3-dipolar cycloaddition of N-crotonoyl- or N-cinnamoylsaccharin as dipolarophile to arylnitrile oxides or nitrile imines using p-HAP300 as catalyst under solvent-free microwave conditions. In this process, the yields were significantly improved compared to classical conditions without alteration of the selectivity. The regioselectivity as well as the nonthermal specific microwave effect are discussed.

Malbari, Khushboo,Saha, Priyanka,Chawla-Sarkar, Mamta,Dutta, Shanta,Rai, Swita,Joshi, Mamata,Kanyalkar, Meena
, (2021/07/19)
A series of scaffolds namely aurones, 3-indolinones, 4-quinolones and cinnamic acid-piperazine hybrids, was designed, synthesized and investigated in vitro against influenza A/H1N1pdm09 virus. Designed molecules adopted different binding mode i.e., in 430-cavity of neuraminidase, unlike sialic acid and oseltamivir in molecular docking studies. All molecules reduced the viral titer and exhibited non-cytotoxicity along with cryo-protective property towards MDCK cells. Molecules (Z)-2-(3′-Chloro-benzylidene)-1,2-dihydro-indol-3-one (2f), (Z)-2-(4′-Chloro-benzylidene)-1,2-dihydro-indol-3-one (2g) and 2-(2′-Methoxy-phenyl)-1H-quinolin-4-one (3a) were the most interesting molecules identified in this research, endowed with robust potencies showing low-nanomolar EC50 values of 4.0 nM, 6.7 nM and 4.9 nM, respectively, compared to reference competitive and non-competitive inhibitors: oseltamivir (EC50 = 12.7 nM) and quercetin (EC50 = 0.56 μM), respectively. Besides, 2f, 2g and 3a exhibited good neuraminidase inhibitory activity in sub-micromolar range (IC50 = 0.52 μM, 3.5 μM, 1.3 μM respectively). Moreover, these molecules were determined as non-competitive inhibitors similar to reference non-competitive inhibitor quercetin unlike reference competitive inhibitor oseltamivir in kinetics studies.
Design, Synthesis, and Anticancer Activity of Cinnamoylated Barbituric Acid Derivatives
Li, Peng-Xiao,Liu, Guo-Yun,Liu, Ren-Min,Liu, Yue,Mu, Wen-Wen,Sun, Ya-Lei,Yang, Jie
, (2022/01/13)
This work deals with the design and synthesis of 18 barbituric acid derivatives bearing 1,3-dimethylbarbituric acid and cinnamic acid scaffolds to find potent anticancer agents. The target molecules were obtained through Knoevenagel condensation and acylation reaction. The cytotoxicity was assessed by the MTT assay. Flowcytometry was performed to determine the cell cycle arrest, apoptosis, ROS levels and the loss of MMP. The ratios of GSH/GSSG and the MDA levels were determined by using UV spectrophotometry. The results revealed that introducing substitutions (CF3, OCF3, F) on the meta- of the benzyl ring of barbituric acid derivatives led to a considerable increase in the antiproliferative activities compared with that of corresponding ortho- and para-substituted barbituric acid derivatives. Mechanism investigation implied that the 1c could increase the ROS and MDA level, decrease the ratio of GSH/GSSG and MMP, and lead to cell cycle arrest. Further research is needed for structural optimization to enhance hydrophilicity, thereby improve the biological activity of these compounds.
