From Drug Discovery & Development, Algorithm Helps Scientists Decipher How Drugs Work Inside the Body:
Researchers at Columbia University Medical Center (CUMC) have developed a computer algorithm that is helping scientists see how drugs produce pharmacological effects inside the body. The study, published in the journal Cell, could help researchers create drugs that are more efficient and less prone to side effects, suggest ways to regulate a drug’s activity, and identify novel therapeutic uses for new and existing compounds.
…The method involves creating a computational model of the network of protein interactions that occur in a diseased cell. Experiments are then performed to track gene expression changes in diseased cells as they are exposed to a drug of interest. The DeMAND algorithm combines data from the model with data from the experiments to identify the complement of proteins most affected by the drug. …
The study’s senior author notes that the process “could accelerate the drug discovery process and reduce the cost of drug development by unraveling how new compounds work in the body.” Read more here.
