Application of particle swarm optimization to understand the mechanism of action of allosteric inhibitors of the enzyme HSD17β13 Open
Understanding a drug candidate's mechanism of action is crucial for its further development. However, kinetic schemes are often complex and multi-parametric, especially for proteins in oligomerization equilibria. Here, we demonstrate the u…
