Abstract: The advances in computers and their
interconnections have enabled various services based on
client-server approach. Thus retrieving chemical
information from local and global networks has now
become easier. The possibilities of specialized
information services like the Scientific and Technical
Information Network providing bibliographic databases,
various databanks, web directories, online journals,
mailing lists and other resources helping to retrieve
information related pharmaceutical chemistry were
compared to global and general server platforms on World
Wide Web. Fast development is obvious and hints are
given for successful conduct of searches or browsing
primary and secondary literature.
Introduction
Pharmaceutical chemistry is a scientific discipline at
the intersection of chemistry and pharmacology involved
with designing, synthesizing and developing
pharmaceutical drugs. It involves the identification,
synthesis and development of new chemical entities
suitable for therapeutic use i.e., drug discovery which
requires exhaustive literature survey. Now days,
Internet has become a major system for knowledge
extraction and education. The amount of available
scientific information is currently growing at an
incredible rate and the literature of Pharmaceutical
Chemistry is dynamic, complex, and enormous. This
information appears in many forms viz., images, text,
video, and speech. To utilize this information, we need
techniques and tools to allow for fast, effective and
efficient access to large amounts of stored information.
As the search for scientific literature is of great
importance for a research worker and not much has been
said about the new methods of information retrieval
which have emerged, here an attempt has been made to
present some of e-resources for study and research work.
The computer being rather a communication tool than a
typewriter substitute enables access to information
services and databases. Chemists were amongst the
earliest users of computers for generating, acquiring or
searching data by accessing to remote computers i.e.
networking. It may be spread either locally i.e., LAN
(Local area network) or widely i.e., WAN (Wide area
network) and especially the whole Internet gives the
possibility of accessing information on machines
anywhere. The most known tasks on the network are
electronic mail, transfer of files, and access to Web
servers. Exchange of information can be done by using
various protocols IP/TCP (Internet Protocol and
Transmission Control Protocol). These protocols pack
transmitted data into packets and routes them to the
addressee. Today the client-server technology prevails
and its widest implementation is the World Wide Web
developed at CERN, a French organization named, Conseil
Européen pour la Recherche Nucléaire" (European Council
for Nuclear Research). Different network tasks are
accomplished using various protocols - language by which
machines communicate. Information on the Web are
retrieved by Hypertext Transfer Protocol (http), files
are sent over using File Transfer Protocol (ftp), on
most UNIX platforms the mail is routed using Simple Mail
Transfer Protocol (smtp). URL (Universal Resource
Locator)5 for instance
http://pbs.acs.org/hotartcl.index.html means that the
computer named pbs.acs.org is accessed with protocol
http and that the requested file is index in HyperText
Markup Language (.html) can be found in directory /
hotartcl/ on that computer. However,.html extension can
be convertible into portable document format (.pdf).
Every computer on the Internet has its own IP address
that corresponds to nearest Domain Name Server (DNS) – a
server especially for that purpose.
