Deregulated expression of the MYC transcription factor occurs in most human cancers and correlates with high proliferation, reprogrammed cellular metabolism and poor prognosis. Overexpressed MYC binds to virtually all active promoters within a cell, although with different binding affinities, and modulates the expression of distinct subsets of genes.… (More)
Positioning of the cleavage plane is regulated to ensure proper animal development. Most animal cells rely on the astral microtubules to position the mitotic spindle, which in turn specifies the cleavage plane. The mouse zygote lacks discernible astral microtubules but still divides symmetrically. Here, we demonstrate a cloud-like accumulation of F-actin… (More)
A novel series of 2-(3-fluoro-4-nitrophenoxy)-N-phenylacetamide compounds were designed, synthesized and in vitro assessed for their antitubercular activities by a microdilution method. All the novel derivatives exerted potent or moderate active against M. tuberculosis H₃₇Rv, with MIC values ranging from 4 to 64 μg/mL. The most potent derivative 3m showed… (More)
Dehydrosqualene synthase (CrtM) is a key enzyme in the synthesis of presqualene diphosphate in Staphylococcus aureus. In the current study, a combination of structure-based pharmacophore and 3D-QSAR methods are used to clarify the essential quantitative structure–activity relationship (QSAR) of known CrtM inhibitors; the multicomplex-based pharmacophore… (More)
Intravesical instillation of Bacillus Calmette-Guérin is currently used as adjuvant therapy for superficial, non-muscle invasive bladder cancer (NMIBC). However, nearly 40% of patients with NMIBC will fail Bacillus Calmette-Guérin therapy. In an attempt to investigate the feasibility of using insect baculovirus-based vectors for bladder cancer therapy, we… (More)
A scaffold-hopping strategy toward Agomelatine based on in silico screening and knowledge analysis was employed to design novel antidepressant agents. A series of 3, 4-dihydroisoquinoline compounds were selected for chemical synthesis and biological assessment. Three compounds (6a-1, 6a-2, 6a-9) demonstrated protective effects on corticosterone-induced… (More)
A series of N-3-substituted 7-aminopyrido[2,3-d]pyrimidin-6-carbonitrile derivatives was readily synthesized and their anti-proliferative activities on five types of tumor cells were evaluated through a cell-based phenotypic screening approach. Compound 3k was found to be potent on human colon cancer SW620 cells with an IC(50) value of 12.5 mM. Structural… (More)
In the title compound, C(13)H(10)FNO(5)S, the dihedral angle between the benzene rings is 47.63 (14)°. In the crystal, π-π stacking occurs between nearly parallel benzene rings of adjacent mol-ecules, the centroid-centroid distance being 3.7806 (16) Å. Weak inter-molecular C-H⋯O hydrogen bonding is also present in the crystal structure.
