Synthesis of pyridine-dicarboxamide-cyclohexanone derivatives: Anticancer and alpha-glucosidase inhibitory activities and in silico study

An efficient and practical method for the synthesis of 2,6-diaryl-4-oxo-N,N0-di(pyridin-2 -yl)cyclohexane-1,1-dicarboxamide is described in this present study, which occurs through a double Michael addition reaction between diamide and various dibenzalacetones. The reaction was carried out in dichloromethane (DCM) in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU). The anticancer activities of the synthesized compounds were evaluated in several cancer cell lines, including MCF-7, MDA-MB-231, SAS, PC-3, HCT-116, HuH-7 and HepG2 cells. From these experiments, we determined that MDA-MB-231 was the most sensitive cancer cell line to the compounds 3c, 3e, 3d, 3j and 3l, which exhibited variable anticancer activities (3l [IC50 = 5 ¡À 0.25 muM] > 3e [IC50 = 5 ¡À 0.5 muM] > 3c [IC50 = 7 ¡À 1.12 muM] > 3d [IC50 = 18 ¡À 0.87 muM] > 3j [IC50 = 45 ¡À 3 muM]). Of these, 3l (substituted p-trifluoromethylphenyl and chloropyridine) showed good potency (IC50 = 6 ¡À 0.78 muM) against HCT-116 colorectal cancer cells and exhibited high toxicity against HuH-7 liver cancer cells (IC50 = 4.5 ¡À 0.3 muM). These values were three times higher than the values reported for cisplatin (IC50 of 8 ¡À 0.76 and 14.7 ¡À 0.5 muM against HCT-116 and HuH-7 cells, respectively). The highest a-glucosidase inhibitory activity was detected for the 3d, 3i and 3j compounds. The details of the binding mode of the active compounds were clarified by molecular docking studies.

Manipulating the Expression Rate and Enantioselectivity of an Epoxide Hydrolase by Using Directed Evolution

We describe here a strategy to improve the expression efficiency and enantioselectivity of Aspergillus niger epoxide hydrolase (ANEH) by directed evolution. Based on a blue-colony screening system using the LacZalpha (beta-galactosidase alpha peptide) complementation solubility reporter, several ANEH variants out of 15000 transformants from a random-mutagenesis library were identified that show improved recombinant expression in E. coli. Among them, Pro221Ser was subsequently used as a template for iterative saturation mutagenesis (ISM) at sites around the ANEH binding pocket. Following four rounds of ISM, a highly enantioselective mutant was identified that catalyzes the hydrolytic kinetic resolution of racemic glycidyl phenyl ether with a selectivity factor of E=160 in favor of the (S)-diol compared to WT ANEH characterized by E=4.6. Expression of this mutant is 50 times higher than that of WT ANEH. It also serves as an excellent stereoselective catalyst in the hydrolytic kinetic resolution and desymmetrization of several other structurally diverse epoxides. Copyright

Naphthalimide-containing conjugated polyelectrolytes with different chain configurations

Several donor-acceptor type conjugated polyelectrolytes containing naphthalimide are developed. Different polymer chain configurations of the backbones of polymers lead to different photophysical properties. The para-substituted polymers show extended conformations with quite low quantum yields in high polarity solvents because of twisted intramolecular charge transfer features, while the meta-substituted polymers can form helices and demonstrated significantly improved quantum yields in water and methanol, as well as achieving sensitive, ultrafast and ratiometric detection of trace methylene blue in water.

Synthesis of both kinetically and thermodynamically controlled diastereomeric pairs of bis-isoxazolidines from dibenzylideneacetone: Their reactivity and biological activity

Reactions of C-aryl-N-phenyl-nitrones with dibenzylideneacetone yielded pairs of diastereomeric bis-isoxazolidines in good to moderate yields. Both types of cycloadducts possessed identical regio- and stereo-selectivity. Molecular modeling studies revealed small difference in energy between the two isomers. Less stable isomer was converted to more stable one via partial cycloreversion followed by re-cycloaddition pathway. Zinc mediated acid catalyzed cycloreversion was observed for more stable diastereomer whereas less stable one yielded corresponding bis-1,3-aminoalcohols in similar condition. Some cycloadducts were screened for anticancer and antibacterial activity.

The stereoselective conversion of 2-alkenyl alcohols to (R)- or (S)- alkane-1, 2-diols using D-glucose as a chiral auxiliary

The stereoselective addition of the 2-hydroxyl group of glucose to the mercurated vinyl group of 2-alkenyl glycosides followed by hydride reduction and removal of the saccharide fragment was used to prepare enantiomerically pure 1,2-dihydroxy alkanes. Diols of (R) or (S) configuration can be synthesized from (alpha)-glycosides or the (beta) form respectively. Demercuration with chloride ion led to the insertion of a halo group adjacent to the new chiral center thus allowing for the possibility of further functionalization.

Design and syntheses of anti-tuberculosis agents inspired by BTZ043 using a scaffold simplification strategy

Tuberculosis (TB), a disease caused by Mycobacterium tuberculosis (Mtb), is a global public health concern because of the emergence of various resistant strains. Benzothiazin-4-ones (BTZs), represented by BTZ043, are a promising new class of agents for the treatment of tuberculosis and have been shown to kill Mtb in vitro, ex vivo, and in mouse models of TB. Herein we report the design and syntheses of nitroaromatic sulfonamide, reverse-amide, and ester classes of anti-TB agents using a scaffold simplification strategy based on BTZ043. The presented work explores the effect of functional groups such as sulfonamides, reverse-amides, and esters that are attached to the nitroaromatic rings on their anti-TB activity. The in vitro activity of the compounds evaluated against the H37Rv strain of Mtb show that nitroaromatic sulfonamides and nitrobenzoic acid esters with two nitro substituents were most active and highlights the importance of the electronic character (electron deficient aromatic ring) of the nitroaromatic ring as a central theme in these types of nitroaromatic anti-TB agents.

A new one-step strategy for the stereochemical assignment of acyclic 2- and 3-sulfanyl-1-alkanols using the CD exciton chirality method

A new one-step strategy is described for the stereochemical assignment of acyclic 2- and 3-sulfanyl-1-alkanols using the CD exciton chirality method. Using the 9-anthroate chromophore for the derivatization of both functional groups, the resulting bisignate CD curves unequivocally allow the determination of the stereochemistry from a single CD measurement. The usefulness of the new method is demonstrated using synthesized optically pure 3-sulfanyl-1-hexanols and 2-sulfanyl-1-hexanols as model compounds. The developed microscale method is also useful for the stereochemical assignment of 1,2- and 1,3-diols. To our knowledge this is the first application of the CD exciton chirality method to acyclic 2- and 3-sulfanyl-1-alkanols.
