Additionally, the number of organic compounds accessed experimentally is 10 8, according to CAS and Beilstein databases which contain records obtained from the scientific papers, those have been published by the scientific community, since 1771. But it is expected that this number will continuously increase by the discovery of new chemical skeletons. Although there are many reports about this range to be accepted as Bohacek defined. In later studies, вЂњthe limits of the chemical spaceвЂќ was drawn to be between 10 18вЂ“10 200, according to the results of the analyses by different methods and descriptors.

While making the predictions, Bohacek regarded chemical groups to be stable and chemical branches, ring structures and stereochemical possibilities were taken into account. Her estimation was pointing to 10 60 chemical compounds making up вЂњchemical spaceвЂќ that was virtually identified by using carbon, oxygen or nitrogen atoms, and by considering linear molecules with up to 30 atoms. In 1996, Regine Bohacek, generated predictions about possible chemical compound types that might be chemically accessed. In 1858, KekulГ© proposed structural theories which successfully followed by different theories from the different scientists leading to the discoveries of new findings. However, to synthesize chemically different organic compounds, structural information had to be explained in a more efficient way. Starting with the first successful in vitro organic synthesis in laboratory by WГ¶hler, it was clear that organic compounds could be produced out of the bodies of the living organisms. Natural compounds are an important source for drugs, helped with improved sensitivity and better means for their biochemical separation. These drugs were obtained from the whole or a fraction of the NPs that contain the active pharmaceutical ingredient. The therapeutic effect was completely produced with natural products (NPs).

Until the 19 th century, the drug discovery and development process was based on the trial and error learning approach for diagnosis and curing the diseases. Such studies demand a strong combination of computational resources and skills, biochemical understanding and medicinal motivation. VS protocols involve searching chemical libraries to identify hit compounds with a putative affinity for a specific biological target (enzyme or a receptor) for further development.Д¬ADD methods in conjunction with VS studies emerged as valuable tools to speed up this long process and limit the cost expansion of R&D. Virtual screening (VS) is a widely applied computational approach, which is performed as a hit identification method in early stages of drug discovery pipeline. Advances in systematic biological screening have generated automated parallel biological screening technologies, called high throughput screening (HTS). Biological screening is used to identify possible target of a hit molecule as a developable drug-candidate as the first step in drug discovery. The process to identify new active pharmaceutical ingredients (API) starts with target identification and validation steps and follows hit identification, lead discovery and lead optimization to acquire safe and effective new drug molecules at the preclinical stage. Pharmaceutical drug discovery is a long-lasting and costly process, spanning over 12 to 15 years and costing about 1вЂ“2 billion US Dollars. This may be a seed for further inter-disciplinary development of VS to be applied by drug hunters. This chapter introduces basic concepts and tools by outlining the general workflows of VS, and their integration to the cloud platforms. to repurpose drugs, with various computational scalability options. Such platforms could also be adapted to be included in different stages of the pharmaceutical R&D process to rationalize the needs, e.g. Chemical datasets can be built, libraries can be analyzed, and structure-based or ligand-based VS studies can be performed with cloud technologies. They are designed to perform VS efficiently, aimed to identify commercially available lead-like and drug-like compounds to be acquired and tested. Such platforms are being developed to try to help researchers with various types of applications to prepare and guide the drug discovery and development pipeline. The increasing number of modular and scalable cloud-based computational platforms can assist the needs in VS studies. Virtual screening (VS) is one of the most often applied CADD methods used in rational drug design, which may be applied in early stages of drug discovery pipeline. Computer Aided Drug Discovery (CADD) methods are being used in this work area with several different workflows.
