lead identification and optimization. Final stage of existing drug discovery processes brings only less than 1% of drug candidate to
market research and its results shown the economic impact of drug discovery program. Hence drug designing is the most vital
curriculum to save the expenditure of drug discovery and development process. The extensive perceptions of drug design in
addition to the knowledge and skills in attendance have structured by the role of countless experts. Still, some fascinating confronts
