NATURAL LEAD COMPOUND IN DRUG DESIGN

Traditionally, it is highly time consuming and expensive process to design ,development and launching of new drug. Natural process research is increasingly Being combined with computer aided drug design technique by the application of chemo informatics method ,we analyze (quantify ) chemical diversity and structural complexity and distribution in chemical space. During this period of new drug development involves around 10-15 yrs and invest high cost,This is done by various researchers and scientist from various field and discipline .The discovery of new drug from natural product are new strategic option in the field of new drug discovery and used as a lead for the further process. During the last decades a large number of biological active compound was screened out from the natural product as a new drug lead compound .The natural product as a new drug lead compound .the natural sources include Plant ,Animal ,Marine-organism ,mineral and micro –organism etc..
