Synthesis and bioactivity of thiazolidin-2-cyanamide derivatives against type III secretion system of Xanthomonas oryzae on rice

Targeting virulence factors of bacterial without affecting their growth and survival, has been an initiative strategy for the development of novel anti-microbial agents. The type III secretion system (T3SS), one of essential and highly conserved virulence factors in most Gram-negative pathogenic bacteria, has been regarded as an effective target that developed new anti-microbial drugs. Xanthomonas oryzae pv. oryzae (Xoo) is one of the most Important bacterial pathogens on rice, which causes leaf blight disease. To discover potential anti-virulence agents against the pathogens, a new series of thiazolidin-2-cyanamide derivatives containing 5-phenyl-2-furan were designed and synthesized. Their structures were characterized by H-1 NMR, C-13 NMR, MS, and elemental analysis. All the title compounds inhibited the promoter activity of a harpin gene hpa1, significantly, that were further checked for the impact on bacterial growth and on the hypersensitive response (HR) caused by Xoo on non-host tobacco plants. The results indicated that treatment of Xoo with the title compounds II-2,II-3 and II-4 resulted in significantly attenuated HR without affecting bacterial growth or survival. Moreover, quantitative reverse transcription-polymerase chain reaction (qRT-PCR) analysis showed that the expression of the Xoo T3SS was suppressed by treatment with the three inhibitors. The mRNA levels of representative genes in the hrp (hypersensitive response and pathogenicity) cluster, as well as the regulatory genes hrpG and hrpX, were reduced. Finally, the in vivo test demonstrated that the compounds could reduce the disease symptoms of Xoo on the rice cultivar (Oryza sativa) IR24.

Structural design, synthesis and pharmacological evaluation of thiazoles against Trypanosoma cruzi

Chagas disease is one of the most significant health problems in the American continent. benznidazole (BDZ) and nifurtimox (NFX) are the only drugs approved for treatment and exhibit strong side effects and ineffectiveness in the chronic stage, besides different susceptibility among T. cruzi DTUs (Discrete Typing Units). Therefore, new drugs to treat this disease are necessary. Thiazole compounds have been described as potent trypanocidal agents. Here we report the structural planning, synthesis and anti-T cruzi evaluation of a new series of 1,3-thiazoles (7-28), which were designed by placing this heterocycle instead of thiazolidin-4-one ring. The synthesis was conducted in an ultrasonic bath with 2-propanol as solvent at room temperature. By varying substituents attached to the phenyl and thiazole rings, substituents were observed to retain, enhance or greatly increase their anti-T. cruzi activity. In some cases, methyl at position 5 of the thiazole (compounds 9, 12 and 23) increased trypanocidal property. The exchange of phenyl for pyridinyl heterocycle resulted in increased activity, giving rise to the most potent compound against the trypomasigote form (14, IC50trypo = 0.37 mu M). Importantly, these new thiazoles were toxic for trypomastigotes without affecting macrophages and cardiomyoblast viability. The compounds were also evaluated against cruzain, and five of the most active compounds against trypomastigotes (7, 9, 12, 16 and 23) inhibited more than 70% of enzymatic activity at 10 mu M, among which compound 7 had an IC50 in the submicromolar range, suggesting a possible mechanism of action. In addition, examination of T. cruzi cell death showed that compound 14 induces apoptosis. We also examined the activity against intracellular parasites, revealing that compound 14 inhibited T cruzi infection with potency similar to benznidazole. The antiparasitic effect of 14 and benznidazole in combination was also investigated against trypomastigotes and revealed that they have synergistic effects, showing a promising profile for drug combination. Finally, in mice acutely-infected with T cruzi, 14 treatment significanty reduced the blood parasitaemia and had a protective effect on mortality. In conclusion, we report the identification of compounds (7), (12), (15), (23) and (26) with similar trypanocidal activity of benznidazole; compounds (9) and (21) as trypanocidal agents equipotent with BDZ, and compound 14 with potency 28 times better than the reference drug without affecting macrophages and cardiomyoblast viability. Mechanistically, the compounds inhibit cruzain, and 14 induces T. cruzi cell death by an apoptotic process, being considered a good starting point for the development of new anti-Chagas drug candidates.

Novel chromenyl-based 2-iminothiazolidin-4-one derivatives as tubulin polymerization inhibitors: Design, synthesis, biological evaluation and molecular modelling studies

Here-in, we present molecular design, chemical synthesis and evaluation of novel chromenyl-based 2-iminothiazolidin-4-one derivatives as tubulin polymerization inhibitors. The newly synthesized compounds were evaluated for their in vitro cytotoxicities against A549 (lung cancer), MDA-MB-231 and BT-471 (breast cancer), HepG2 (liver cancer) and HCT-116 (colon cancer) cell lines by MTT assay. Among the synthesized compounds, compound 12b showed excellent anticancer activity on MDA-MB-231 cell line with IC50 value of 0.95 +/- 1.88 mu M and was verified to be safe in normal human bronchial epithelial cells (Beas-2B). Apoptosis induced by the lead 12b was observed using morphological observations, AO/EB and DAPI staining procedures. Further, dose-dependent increase in the depolarization of mitochondrial membrane was also observed through JC-1 staining. Annexin V-FITC/PI assay confirmed that 12b induced early apoptosis. Additionally, cell cycle analysis indicated that the MDA-MB-231 cells were arrested at sub-G2/M phase and also inhibited tubulin polymerization with IC50 value of 3.54 +/- 0.2 mM. Molecular docking simulations were employed to identify the important binding modes responsible for the tubulin inhibitory activity, thus supporting their effective anticancer potential.

Design and Development of Novel 1,3,5-Triazine-Procaine Derivatives as Protective Agent against Myocardial Ischemia/Reperfusion Injury via Inhibitor of Nuclear Factor-kappa B

The aim of the present study was to determine the protective effect of novel 1,3,5-triazine-procaine derivatives against myocardial ischemia/reperfusion (I/R) injury. Initially, the experiment has been started by the synthesis of procaine, which later got substituted with diverse 1,3,5-triazine derivatives to furnish the final compounds. The target compounds were tested for nuclear factor-kappa B (NF-kappa B) inhibitory activity in lipopolysaccharide (LPS)-stimulated RAW264.7 cells. The antioxidant activity of most potent compound 9i was investigated using hydroxyl radical, DPPH, and superoxide anion scavenging assay. Compound 9i was further evaluated for protective effect against myocardial I/R injury on the basis numerous parameters, for example, hemodynamic parameters (left ventricular developed pressure [LVDP], +/- dp/dt_max, coronary flow [CF], and heart rate [HR]), myocardial enzymes (creatine kinase and lactate dehydrogenase), thiobarbituric acid reactive substance (TBARS), oxidative stress (super oxide dismutase [SOD], catalase [CAT], glutathione [GSH], and glutathione peroxidise [GPx]), histopathology, western blots analysis for B-cell lymphoma 2 (Bcl-2), Bcl-2-associated x protein (Bax), lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1), and NF-kappa B in cardiac tissues. Compounds showed significant inhibition of NF-?B transcriptional activity in LPS-stimulated RAW264.7 cells, revealing compound 9i as a most potent derivative. In vitro results showed efficient reduction of reduced hydroxyl radical, DPPH, and superoxide anion by 9i. The level LVDP, +/- dp/dtmax, CF, HR, TBARS, SOD, CAT, GSH, GPx, and damaged cardiac histopathology were completely restored to normal in 9i-treated group, as compared to I/R group. In western blot analysis, the expression of Bax, LOX-1, and NF-kappa B was found to be decreased, while the level of Bcl-2 was found to be increased in 9i-treated group. The procaine-1,3,5-triazine derivatives showed significant cardioprotective action via inhibition of NF-kappa B.

Expedient synthesis of novel antibacterial hydrazono-4-thiazolidinones under catalysis of a natural-based binary ionic liquid

A library of pyran-2H-one-3-ylmethylidene and chromene-2H-one-3-ylmethylidene derivatives of the titled heterocyclic framework was synthesized from 3-acyl-4-hydroxypyran/chromene-2H-one via sequential reaction with thiosemicarbazide and dialkyl acetylenedicarboxylates. The syntheses were carried out under efficient catalysis of a new binary ionic liquid mixture [l-prolinium chloride][1-methylimidazolium-3-sulfonate] in one pot and solvent-free conditions. Calculations based on density functional theory displayed that the barrier energy for interconversion of the two possible diastereomeric isomers of each product is less than the thermal energy of molecules at room temperature, as only one product can be resolved from a given reaction mixture. This seems to be the case for the previously reported hydrazonothiazolidines. The binary ionic liquid mixture melts at near room temperature and can be considered as a solution of HCl in 1:1 mixture of two zwitterionic species. It proved to be more efficient than its constituents in catalyzing the above synthesis in one-pot operation. Some of the synthesized products have shown pronounced antibacterial activities. The ionic liquid is virtually stable in air and moisture, as can be retrieved several times without appreciable decrease in its catalytic activity. Graphic abstract
