In the last few years, the use of lab automation, robots, and artificial intelligence in drug discovery has advanced dramatically as it allows lifesaving drugs to reach the right person at the right time.
FREMONT, CA : The COVID-19 outbreak has revealed to the world a critical issue—the urgent need to produce effective treatments. But it is easier said than done to manufacture a new medicine. A concept that the inhibition or activation of a target molecule or pathway causes a therapeutic effect is the starting point for drug development. The hit-to-lead and lead optimization phases follow target identification and validation. It entails discovering hit molecules with a high affinity for the target and choosing the "best" molecule to proceed with.

Despite the resources committed to developing lead compounds, there is always a risk that a drug will not advance to the following research stage. Lead optimization can also be an extensive procedure that is expensive and time-consuming. Due to this complicated and risky approach, there has been a lot of interest in enhancing drug discovery success rates, and one such method is automation.
Automation refers to technological advancements that have the potential to revolutionize the drug development process. Automation can enhance laboratory efficiency, reduce overall attrition, and reduce costs along the drug discovery value chain. When combined with automated data processing, new technologies like microfluidics, robotics, and artificial intelligence can assist speed up the drug research and approval process, allowing patients to receive therapies quickly.
High‐throughput screening
High-throughput screening (HTS) evaluates the activity of a wide range of compounds against a specified biological target utilizing automated equipment. The main benefit of adopting high-throughput screening in lead identification is the ability to test numerous agents (small compounds or functional genomics tools) in a quick and repeatable manner.
HTS can be considered a quick scan of biological processes that allows candidates with insufficient or no effect to be quickly ruled out of the drug discovery process.
Automation allows for testing more significant numbers of hypotheses
Automation enhances data accuracy, precision, reproducibility, and transparency, in addition to lowering costs and shortening timescales, allowing researchers to use high-quality data in hypothesis-driven research.
Researchers can evaluate a larger number of hypotheses with automation, and it can enable sophisticated workflows and screening scenarios that would otherwise be difficult or impossible to execute manually.
Improving accuracy and reproducibility with Robotics
Robotics increases the overall efficiency of a process by automating the completion of pre-defined activities. Robots are unstoppable, parallel-processing machines that can handle several sequential phases in any workflow at the same time without pausing or "taking breaks."
Another element that increases the popularity of robots in automation is precision. The robotic systems can dramatically improve the accuracy and reproducibility of the data collection procedure and quality, which is difficult for a researcher to do manually.
