Activity guided fractionation of the ethanolic extract of the leaves of the P. longifolia var. pendula led to the identification of quercetin 1, quercetin-3-O-ß-glucopyranoside 2, kaempferol-3-O-α-rhamnopyranosyl-(1→6)- ...

A novel series of thermally stable yellow light emitting fluoranthene with an amine donor and a nitrile acceptor was prepared from a ketene-S,S-acetal under mild conditions without using an organometal catalyst. The organic ...

Three pairs of enantiomeric 2'-deoxy nucleoside analogues (4a, 4b), (4c, 4e) and (4d, 4f) respectively have been synthesized from enantiomerically pure highly functionalized furanoid glycals 2a-d by involving the similar ...

The pleiotropic functions of disaccharide trehalose in the biology of nematodes and its absence from mammalian cells suggest that its biosynthesis may provide a useful target for developing novel nematicidal drugs. The ...

The objective of this study was to determine the in vitro osteogenic activities of selected medicinal plants used traditionally in India. The compounds isolated from three plants viz. Allophylus serratus, Cissus quadrangularis ...

The chemotherapy of visceral leishmaniasis (VL) has several limitations including resistance and toxicity of the existing drugs. Downregulation of immune system further aggravates the problems. To combat this situation,l ...

The potential of chitosan microparticles as a carrier of doxorubicin for the treatment of visceral leishmaniasis was evaluated by macrophage mediated drug targeting approach. Cationic charge of doxorubicin was masked by ...
