    Silver Patterned Supramolecular Liquid Crystalline Gel as Electrochemical Sensor of Tyrosine

    Rohini K.Narayanan, Neethu K. Sadanandhan, and Sudha J. Devaki*
    Here, we have prepared silver nanoparticle patterned functional
    liquid crystalline gels (SFLAG) through self-assembly
    process. The surface plasmon energy of SFLAGs were observed
    at ~ 420 nm and FCC lattices of silver particles were confirmed
    with XRD. Formation of liquid crystalline gel phase was studied
    by microscopic techniques and rheology. [...]

    Catalyst controlled straightforward synthesis of highly substituted pyrroles/furans via propargylation/cycloisomerization of α-oxoketene-N,S-acetals

    DOI: 10.1021/acs.joc.6b02367
    Ganesh Chandra Nandi* and Soumini K.
    Abstract A facile and efficient InCl3 catalyzed one-pot synthesis of highly substituted pyrroles has been developed via a tandem propargylation/cycloisomerization reaction of α-oxoketene-N,S-acetals with propargyl alcohols. Notably, in the presence of Bronsted acid p-TSA.H2O, the reaction afforded the hydrolyzed product propargylated-1,3-dicarbonyl compounds, which upon treatment with Cs2CO3 underwent [...]

    Licarin B from Myristica fragrance improves insulin sensitivity by activating PPARγ and subsequently up-regulating GLUT4 via PI3/AKT Signaling Pathway

     
    Peroxisome proliferator-activated receptors (PPARs) are ligand-dependent transcription factors regulating lipid and glucose metabolism. Ongoing drug discovery programs aim to develop partial PPARγ agonists devoid of the side effects of the marketed antidiabetic agents thiazolidinediones. Here, we evaluated the therapeutic potential of Licarin B (LB), a major bioactive constituent of Myristica fragrans in improving peroxisome proliferator-activated [...]
