Drug Discovery and Development in Cancer Research

Drug discovery is a process where cure for the disease is found. This is a multistep process which involves a great amount of investment in terms of time and finance.

Cancer is believed not be cured any drugs. However there are many instances where people have come out of this disease successfully, thanks to the researchers who have developed some efficient molecules which can supress and kill the tumor cells.

As a first step the cause for the disease is identified. Here it might be a molecule or an Organism. Once the cause is identified, hypothesis for the target molecules are drawn and certain molecule groups are chosen to encounter the target molecule/Organism. In the modern method, these molecules are chosen by algorithms and often selected from the databases based upon their structures and composition. Later these are subjected to the target molecule in silico models. Many of the molecules lose the race here and few make it to the next level of testing where the selected models are subjected to animal models. Once these molecules are proven to be safe and efficient in the animal models, they are approved to test on the human. After rigour testing and monitoring, a suitable molecule with all ideal characteristics is approved by the governing body and released into market.
