CD and NMR studies on the aggregation of amphotericin-B in solution.
We report in this paper the aggregation properties of amphotericin-B (amp-B) in solution using CD and 1H-NMR techniques. Our results indicate that the preferred structure of amp-B in… Expand
Parasitic infection of some wild animals at Thekkady in Kerala
Helminthic infection is wide spread in wild animals and may cause mortality and morbidity of varying degrees. Gour et al. (1979) and Fowler (1986) have stated that the wild animals in the free-living… Expand

ALUMINIUM exposure has been shown to result in aggregation of microtubule-associated protein tau in vitro. In the light of recent observations that the native random structure of tau protein is… Expand
Hydrogen-1 and carbon-13 magnetic resonance studies of nonactin-calcium complex.
For an understanding of the cation selectivity and general binding characteristics of macrotetralide antibiotic nonactin (NA) with ions of different sizes and charges, the nature of binding of… Expand
A 13C spin‐lattice relaxation study of dipeptides containing glycine and proline: Mobility of the cyclic proline side chain
Molecular dynamics of the cyclic dipeptides cyclo(Gly‐L‐Pro), cyclo‐(L‐Pro‐L‐Pro), and cyclo(L‐Pro‐D‐Pro) and the linear dipeptides L‐Pro‐Gly and cis and trans Gly‐L‐Pro were studied in neutral… Expand
Circular dichroism and nuclear magnetic resonance studies on the complexation of valinomycin with calcium.
Complexation of valinomycin (VM) with the divalent cation Ca2+ in a lipophilic solvent, acetonitrile (CH3-CN), has been studied by using circular dichroism and proton and carbon-13 nuclear magnetic… Expand

Molecular self-assembly is of key importance for the rational design of advanced materials. To investigate the causal relation between molecular structure and the consequent self-assembled… Expand
Conformational and ion binding properties of a cyclic octapeptide, cyclo(Ala‐Leu‐Pro‐Gly)2
The conformation and ion‐binding characteristics of a cyclic octapeptide, cyclo(Ala‐Leu‐Pro‐Gly)2, in a liphophilic solvent, acetonitrile, have been studied using CD and nmr spectroscopy. The peptide… Expand
Carboxylic ionophore (lasalocid A and A23187) mediated lanthanide ion transport across phospholipid vesicles.
The transport kinetics of three lanthanide ions (viz., Pr3+, Nd3+, and Eu3+) across dimyristoylphosphatidylcholine and dipalmitoylphosphatidylcholine unilamellar vesicles mediated by the two… Expand
Lipid-amphotericin B complex structure in solution: a possible first step in the aggregation process in cell membranes.
The interactions between the polyene antibiotic amphotericin B with dipalmitoylphosphatidylcholine were investigated in vesicles (using circular dichroism) and in chloroform solution (using circular… Expand
