A small-molecule cell-based screen led to the identification of biphenylimidazoazines with highly potent and broad-spectrum anti-apicomplexan activity

An in vitro screening of the anti-apicomplexan activity of 51 compounds, stemming from our chemical library and from chemical synthesis, was performed. As a study model, we used Toxoplasma gondii (T. gondii), expressing beta-galactosidase for the colorimetric assessment of drug activity on parasites cultivated in vitro. This approach allowed the validation of a new series of molecules with a biphenylimidazoazine scaffold as inhibitors of T. gondii growth in vitro. Hence, 8 molecules significantly inhibited intracellular replication of T. gondii in vitro, with EC50 < 1 muM, while being non-toxic for human fibroblasts at these concentrations. Most attractive candidates were then selected for further biological investigations on other apicomplexan parasites (Neospora caninum, Besnoitia besnoiti, Eimeria tenella and Plasmodium falciparum). Finally, two compounds were able to inhibit growth of four different apicomplexans with EC50 in the submicromolar to nanomolar range, for each parasite. These data, including the broad anti-parasite spectrum of these inhibitors, define a new generation of potential anti-parasite compounds of wide interest, including for veterinary application. Studies realized on E. tenella suggest that these molecules act during the intracellular development steps of the parasite. Further experiments should be done to identify the molecular target(s) of these compounds. One of the oldest and most widely used commercial enzyme inhibitors is aspirin, Recommanded Product: 187973-60-0, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation. you can also check out more blogs about 187973-60-0

Studies on anti-platelet agents. V. Synthesis and structure-activity relationship of 3-substituted 5,6-bis(4-methoxyphenyl)-1,2,4-triazines

The syntheses and structure-activity relationships of a series of 3-substituted 5,6-bis(4-methoxyphenyl)-1,2,4-triazines as anti-platelet agents based on cyclooxygenase (CO) inhibition are described. Of these compounds, 1-[5,6-bis(4-methoxyphenyl)-1,2,4-triazin-3-yl]carbonyl-4-methylpipera zine (10) exhibited potent CO inhibition in vitro (IC50 = 2.8 x 10-7 M) with vasodilatory activity (ED50 = 4.5 x 10-5 M). Compound 10 also showed potent ex vivo activities, completely preventing platelet aggregation induced by arachidonic acid and collagen at 6 h after oral administration of 3.2 and 1.0 mg/kg. The ex vivo potency of 10 is more than three times that of aspirin. Moreover, 10 demonstrated no gastrointestinal side effect in rats even at 100 mg/kg in spite of its potent CO inhibition activity, while aspirin, the most widely-used anti-platelet drug, showed gastrointestinal side effects in a dose-dependent manner (32, 100, and 320 mg/kg) in our study. These results suggested that 10 is a very attractive candidate for development as an anti-platelet drug since an aspirin-like anti-platelet agent, based on CO inhibition and being free from gastrointestinal side effects, is a major goal of thromboembolic research.

Synthesis of N-alkyl-N-methyl amino acids. Scope and limitations of base-induced N-alkylation of Cbz-amino acids

The reaction of N-benzyloxycarbonyl derivatives of aliphatic amino acids with NaH/alkyl iodides gave the corresponding N-Cbz-N-alkyl derivatives in good to high yields. The scope and limitations of this simple N-alkylation reaction were investigated as a convenient and flexible attempt to prepare unsymmetrically N,N-diprotected alpha-amino acids. The procedure is based on the N-alkylation of N-carbamoyl amino acids, a one-pot deprotection/protection sequence without extensive purification of the products. Protection of the carboxyl function is not required while the starting materials are inexpensive and commercially available.

Evaluation of potential genotoxic and cytotoxic effects of deltamethrin insecticide on somatic chromosomes of Helianthus annuus L.

In this research, the genotoxic and cytotoxic effects of the insecticide deltamethrin (DEL) on the root meristem cells of sunflowers (Helianthus annuus L.) were investigated. The lethal dose (LD50) value was determined as approximately 1?ppm in the sunflower root growth tests. The roots were treated with 1 (LD50), 0.25 (LD50/4), 0.5 (LD50/2) and 2?ppm (LD50 ¡Á2) concentrations of DEL for 24, 36 and 48?h, with a control for each combination. Occurring morphological changes such as reduction of root elongation and discoloration in sunflower roots were observed with the using DEL concentrations. The mitotic index and mitotic abnormalities were determined in both control and test groups. Mitotic index reduced with increasing the insecticide concentration at each exposure time. The mitotic abnormalities were recorded as disturbed prophase, c-mitosis, stickiness, laggards and chromatid bridges. In addition, micronucleus was observed at interphase and its frequency was calculated in the test solutions.

N-aryl heterocycles via coupling reactions with arylboronic acids

Compounds having a partial 2-pyridone structure or 3-pyridazinones can be selectively N-arylated with phenylboronic acids according to the procedure described by Chan and Lam. This procedure leads to N5-arylated imidazo[4,5- c]pyridin-4-ones, precursors of potent factor Xa inhibitors. In addition, the synthesis of N-aryl substituted pyrrole- and indole-2-carboxylic acid esters is described. In the indole series this procedure offers a flexible entry in the synthesis of different 1,3-diaryl-2-carboxyindoles.
