Synthesis and cancer growth inhibitory activities of 2-fatty-alkylated pyrrolidine-3,4-diol derivatives
(Arkat USA, 2014)
A series of new amphiphilic pyrrolidines containing dodecyl and oleyl apolar side chains were prepared and evaluated for their ability to inhibit the growth of pancreatic ductal adenocarcinoma cells in vitro. The new ...

The nodulation of Alfalfa by the acid-tolerant Rhizobium sp. Strain LPU83 does not require sulfated forms of Lipochitooligosaccharide nodulation signals
(American Society for Microbiology, 2011)
The induction of root nodules by the majority of rhizobia has a strict requirement for the secretion of symbiosis-specific lipochitooligosaccharides (nodulation factors [NFs]). The nature of the chemical substitution on ...

Structural basis of pharmacological chaperoning for human β-galactosidase
(Elsevier, 2014)
GM1 gangliosidosis and Morquio B disease are autosomal recessive diseases caused by the defect in the lysosomal β-galactosidase ( β-Gal), frequently related to misfolding and subsequent endoplasmic reticulum-associated ...

Development of polycationic amphiphilic cyclodextrin nanoparticles for anticancer drug delivery
(2017)
Background: Paclitaxel is a potent anticancer drug that is effective against a wide spectrum of cancers. To overcome its bioavailability problems arising from very poor aqueous solubility and tendency to recrystallize upon ...

New Castanospermine Glycoside Analogues Inhibit Breast Cancer Cell Proliferation and Induce Apoptosis without Affecting Normal Cells
(Public Library of Science, 2013)
sp2-Iminosugar-type castanospermine analogues have been shown to exhibit anti-tumor activity. However, their effects on cell proliferation and apoptosis and the molecular mechanism at play are not fully understood. Here, ...

Trehalose-based Siamese twin amphiphiles with tunable self-assembling, DNA nanocomplexing and gene delivery properties
(The Society, 2019-06-19)
An original family of multivalent vectors encompassing gemini and facial amphiphilicity, namely cationic Siamese twin surfactants, has been prepared from the disaccharide trehalose; molecular engineering lets us modulate ...

Strongly Emissive and Photostable Four-Coordinate Organoboron N,C Chelates and Their Use in Fluorescence Microscopy
(Wiley-Blackwell, 2015)
Six strongly fluorescent four-coordinate organoboron N,C chelates containing an aryl isoquinoline skeleton were prepared. Remarkably, the fluorescence quantum yields reach values of up to 0.74 in oxygen-free toluene. The ...

Exopolysaccharide Production by Sinorhizobium fredii HH103 Is Repressed by Genistein in a NodD1-Dependent Manner
(Public Library of Science, 2016)
In the rhizobia-legume symbiotic interaction, bacterial surface polysaccharides, such as exopolysaccharide (EPS), lipopolysaccharide (LPS), K-antigen polysaccharide (KPS) or cyclic glucans (CG), appear to play crucial roles ...

Osmotic stress activates nif and fix genes and induces the Rhizobium tropici CIAT 899 Nod factor production via NodD2 by up-regulation of the nodA2 operon and the nodA3 gene
(Public Library of Science, 2019)
The symbiosis between rhizobia and legumes is characterized by a complex molecular dialogue in which the bacterial NodD protein plays a major role due to its capacity to activate the expression of the nodulation genes in ...
