Research Areas
Between October 1976 - August 1978 1 have worked as a Research and Development chemist at Ms.
Reichhold Chemicals (Ind.) Ltd. on the research and development of following polymers.
a) Alkyd resins
b) Unsaturated polyesters
c) Phenol-formaldehyde resins (resoles and novolaks)
d) Urea-formaldehyde resins, and
e) Epoxy resins
NMR Studies of Biological molecules:
I have long been associated with nuclear magnetic resonance spectroscopic investigations of a
large number of biological systems since my PhD work in 1978. During the course of these
investigations multinuclear - 1

Cl NMR studies of biological
systems investigated include biological molecules with varying degrees of complexities. Conformational
aspects, structure-function correlation and interactions between biomolecules were some of the problems
which were investigated by me. Active site of ribonuclease A was explored with respect to the role of
lysine 41(an active site residue) in the catalytic activity of the enzyme. Detection of polyamines in
belladonna mottle virus and its role in stabilising the virus assembly was investigated by NMR.
Interaction of cupric isonicotinohydrazide (isoniazid) with calf-thymus DNA was studied in relation to
its ability to cleave DNA. Conformation of an antibiotic ionophore A23187 in polar and non-polar
solvents was studied to understand its role in transferring divalent metal ions across the biological
membranes. Structure of curcumin-BF2 complex was explored to stabilise curcumin. Carbon and
phosphorus metabolism, secondary metabolite production, intracellular pH, and permeabilisation of
intact cells by detergents were investigated with reference to intact cell systems of Thermomyces
lanuginosus, Rhodotorula gracilis, Kluyveromyces fragilis and Saccharomyces cerevisiae. Unusual
biphasic melting behaviour of Rhodotorula gracilis DNA was studied by CD and UV measurements.
Crystallinity in natural polysaccharides by solid-state 13C NMR was also investigated. The above
mentioned studies have so far resulted in 16 publications in National and International Journals which
were also citated by other researchers.

Cyclodextrin Chemistry:
I have been exploring for the last fifteen years (since 1987) various aspects of inclusion
complex formation by ß- cyclodextrin. Structures of several food additive inclusion complexes with ß –
cyclodextrin like aspartame, linoleic and arachidonic acids, substituted phenols, naringin and
cholesterol were investigated by NMR (through one and two dimensional techniques). Orientation of
the above mentioned guest molecules inside ß-cyclodextrin cavity was investigated with respect to the
selectivities exhibited by the inclusion complexes in chemical reactions on the exposed or buried regions
of these guest molecules to produce food additives of commercial importance used in foods. They
include mainly flavour compounds. Enzyme mimicking abilities of ß-cyclodextrin were also explored.
Regio, stereo and chemoselective organic reactions were carried out to prepare menthols from
menthone, thymol and pulegone through hydrogenation and other reduction reactions. Inclusion of
cholesterol inside ß-cyclodextrin cavity was made use of to develop a process to prepare low cholesterol
egg and egg powder. Similar property of ß-cyclodextrin was made use to decaffeinate coffee. Work on
preparation of stereoregular polymers by inclusion polymerisation have also yielded stereoregular
polymers (polyacrylonitrile, polystyrene and poly acyrylonitrile-styrene copolymer) with desired film-
forming properties. ß-Cyclodextrin as a phase-transfer catalyst was investigated in few reactions.
Oxidative potentiality of Cu(II) - ß-cyclodextrin was investigated in few selective oxidative reactions
involving cyclic secondary alcohols like menthol, borneol, isoborneol and cholesterol and other
compounds like eugenol. These investigations have resulted in about 40 publications, 8 Indian Patents
and 1 process. Some of these publications have received good number of citations from other
researchers as well.
Enzyme Catalysed Transformations
Since 1996 lipases and amyloglucosidase catalysed esterification reactions in non-polar solvents
and non-solvent conditions were also investigated by me to produce food additives like flavour and
sufactant esters. Synthetic strategies at both shake flask and large scale levels have been developed.
Several novel methods have been attempted to overcome problems like water activity, microaqueous
pH, alcohol inhibition and hydrolysis. Several basic research aspects of lipase catalysis were
investigated like catalysis by Ping Pong Bi Bi mechanism and enzyme inhibition by the alcohol.
Thermal stability of the lipase in non-polar solvents was investigated. Mathematical modelling of lipase
catalysed reactions by employing extensive Response Surface Methodology and Artifical Neural
3

Network studies were carried out. Optimisation studies to achieve maximum conversions using larger
substrate concentrations with lesser enzyme have been carried out to arrive at conditions for large scale
conversions. A novel experimental set-up was arrived at for carrying out lipase mediated reactions at
higher concentration levels. All the estersand glucosides prepared possess food applications. Low
molecular weight bio-degradable poly-esters were also prepared using lipases in non-polar solvents.
These studies have resulted in more than 80 publications and 13 patents so far.
The food additive preparations investigated so far are,
1. Esters of α-terpinol, lactic acid, cresols and anthranilic acid, with low and high molecular weight
organic acids which are used as flavour and fragrance molecules.
2. Bio-degradable polyesters like poly-lactic acids, polycaprolactone. Poly-p-hydroxy benzoate, poly-
p-benzamide and poly adipates.
3. Amino acid esters of sugars – L-alanyl, L-valyl, L-leucyl, L-isoleucyl, L-prolyl, L-phenylalanyl, L-
tryptophanyl and L-histidyl esters of D-glucose, D-galactose, D-mannose, D-arabinose, D-ribose,
maltose, lactose, sucrose, D-mannitol and D-sorbitol.
4. Glycoside preparations Studied: alkyl , n-octyl-, guaiacyl, eugenyl, curcumin, vanillyl, N-
vanillylnonamide, riboflavinyl, thiamine, pyridoxine, retinyl, ergocalciferol, cholecalciferol, α-
tocopherol,L-Dopa, dopamine, serotinonyl, epinephryl glycosides.
