Abstract

The prevailing trends in the educational system seems to be not
satisfactory both to the teaching community (inclusive of parents) as well
as to the students. One of the main grumbles about the formal education
system seems to be the necessity to conform to the grading and marking
criteria of evaluation process. The student’s grudge is that the curricular
contents and the teaching evaluation leave them with no better scope than
to memorize and recall at the examination hours. The teachers seem to be
discontent with the way the students get away meritoriously merely by the
storage retrieval mechanisms and not by any other contribution to the
contents of the curriculum by way of retrospective revisions and in depth
grasp of contents by reflecting on the pros and cons of the inferences. In
this talk, an effort would be made to highlight on the effective ways of
dealing with “information” based on the personal experiences of teaching
the subject of Chemistry.

radicals, expose this to a magnetic field and monitor the yield of
the CO2, H2 etc., to infer the magnetic field effects. In the reactor
it should be possible to provide for application of a magnetic
field; in particular, if the field required is weak in the sense of a
few Oertsteds, then a electromagnet can take care of the needs.
Since, the triplet spin states T± are split in a magnetic field (which
may be degenerate in the absence of field) the magnetic field
strength for the Zeeman interaction energy to compare with
respect to the spin orbit coupling strength is a determining factor.
If the splitting of T± in presence of the magnetic field is relatively
large, then it is only by the difference in the ‘g’ factors of the
electrons in the two radical which might cause the triplet-singlet
inter conversion by the difference precession rates. Then with
whatever probability the Singlet and Triplet states form as the
radicals diffuse to closer distances would be retained without
much change. Thus varying the magnetic field strengths from
zero to a higher value gradually and monitoring the yields
(degradation efficiencies) would be a certain way to ascertain the
magnetic field effects and further construct models to regulate the
mechanistic aspects related to the magnetic field effects. This
would further enable a suitable water treatment reactor plant for
the efficient photocatalytic oxidative reductions. Moreover, when
the reactor plants are designed for a large turnover of treated

water, even small increase in efficiency by application of
magnetic field could be prove highly economical proposition.
In conclusion, in the present context, it seems worthwhile to
consider an experimental study for the magnetic field effects on
the efficiency of AOP using UV/TiO2/H2O2.

NATURAL PRODUCT CHEMISTRY, METABOLOMICS
AND THEIR UTILITY FOR ENVIRONMENTAL STUDIES

S. Aravamudhan, Department of Chemistry, North Eastern Hill University

Keywords: Natural Products, Metabolism, Medicinal Chemistry, Biology

ABSTRACT

Conventionally the natural product chemistry consists of extracting
from plant resources and analyzing for the constituents to isolated
molecular systems and further characterizing and reporting a
synthetic route for the compounds. In fact, generally in living
systems which naturally require inputs for growth produce such
intermediates and products that play a role synergistically and it is
necessary to know their importance exactly in the path where they
alter the course or determine the subsequent stages. Analytical
methods, specifically the spectroscopic techniques have provided
such possibilities which are these days known as “high throughput”
methods and the metabolomics is a branch of study which escalates
the natural product chemistry to encompass much greater
dimensions and results in medicinal chemistry also getting the due
recognition as the frontier research aspect? It is also possible to
derive benefits from the Theoretical calculation-methods of
molecular interactions in order to reinforce the procedures adapted
by the experimental methods, in particular to mention the CADD,
Computer Aided Drug Design.

It is being envisaged to summarize these recent trends in such
a way that the beginners in the area of Research in Chemistry would
be able to find relevant simple tasks to accomplish to reach out for
an advanced research outlook for their career.

INTRODUCTION
Conventionally the natural product chemistry consists of
extracting from plant resources and analyzing for the constituents
to isolated molecular systems and further characterizing and
reporting a synthetic route for the compounds. The Natural
Products are produced by living cells. They are either produced as
primary metabolites, which are used by the cells for their own
function or biosynthesized as secondary metabolites for various
purposes, most of which unknown to us. (Page-29, Section 2.1
Natural Products, Chapter 2 Chemical Space and the difference
Between Natural Products and Synthetics, by Sheo B.Singh and
J.Chris Culberson, in Natural Product Chemistry for Drug
Discovery, Edited by Antony D. Buss and Mark S. Butler, RSC
Biomolecular Seies No.18, RSC Publishing Royal Society of
Chemistry 2010). Metabolites are the products occurring at the
various stages in the metabolic pathways, and metabolism itself
can be illustrated schematically as in the figure below. Thus this
means the ways and means by which the inter conversion of
smaller and larger molecules occur in living systems. Biological
function of the large molecules, considering the structure-function
correlations, depend on the structures determined by the
component small molecule building blocks/units, and how the
large molecules react to the presence of small molecules in terms
of the reactivity of small molecules and the corresponding active
