Histone deacetylases (HDACs)-mediated epigenetic mechanisms play critical roles in the homeostasis of histone acetylation and gene transcription. HDAC inhibitors have displayed neuroprotective properties in animal models for various neurological diseases including Alzheimer's disease and ischaemic stroke. However, some studies have also reported that HDAC(More)
A novel series of glucosyl thioureas were synthesized in good overall yields (up to 37% over four steps) from d-glucose and primary amines, and their larvicidal activities toward Mythimna separata Walker were also investigated. This new class of glucosyl thioureas demonstrated low to moderate growth inhibition activity of Mythiman separata Walker, with a(More)
Well-defined unnatural dipeptide-alcohols based on a cis-2,5-disubstitued pyrrolidine backbone were synthesized from commercially available starting materials meso-diethyl-2,5-dibromoadipate, (S)-(-)-1-phenylethylamine, and phenylalaninol. The structures of these unnatural dipeptide-alcohols are supported by HRMS, 1H- and 13C-NMR spectroscopy. These(More)
The production of IFN- I (IFN-α/β) is one of the earliest and most important host-protective responses. Interferon regulatory factor 3 (IRF3) is a critical transcriptional factor in the IFN-β signaling pathway. Although significant progress has been achieved in the regulation of IRF3, the process may be more complicated than previously considered. In the(More)
In the title compound, C(18)H(16)N(4)O(3)·H(2)O, the dihedral angles between the triazole ring and the phenyl rings are 84.8 (4) and and 39.8 (4)°. The phenyl rings make a dihedral angle of 84.5 (9)°. In the crystal, the molecules are linked by N-H⋯O and O-H⋯N hydrogen bonds. An intra-molecular O⋯N inter-action also occurs [2.827 (3) Å].
The well-defined unnatural dipeptides based on cis-2,5-disubstituted pyrrolidine backbone were synthesized from commercially available starting materials meso-diethyl-2,5-dibromoadipate, (S)-(−)-1-phenylethylamine, and phenylalanine. The configurations of all the chiral centers in these unnatural dipeptides are confirmed by X-ray crystal diffraction(More)
In the title compound, C(19)H(19)NO(13), one of the two fused furan-ose rings adopts an envelope conformation whereas the other displays a twisted conformation. The crystal structure is stabilized by inter-molecular C-H⋯π inter-actions between a methine H atom and the triacetoxy-phenyl ring of an adjacent mol-ecule, and by weak non-classical inter-molecular(More)
