Fragment-Vased Drug Design (IMAGE) Ohio Supercomputer Center Caption A simulation created at the Ohio Supercomputer Center by Ohio State’s Chenglong Li, Ph.D., illustrates MDL-A (ball-and-stick) binding with a section of GP130 (yellow ribbon). Li is using fragment-based drug design to block Interleukin-6, a small protein molecule that plays a role in breast and prostate cancer.
