This is amino acids 86 to 100 fragment of class II-associated invariant chain peptide called CLIP. The major histocompatibility complex class II molecule displays peptide fragments of foreign proteins to trigger a defensive reaction from the immune system. Before insertion of the foreign peptides into the binding groove, a place-holding peptide CLIP is removed. This is accomplished by the molecule DM, which is shown to increase the dissociation rate of a CLIP peptide from class II.

GRL-0820 (SARS-CoV-2-IN-6) is a potent SARS-CoV-2 3CLpro inhibitor that can be used to study novel coronavirus infections.

S3QEL-2 is a selective complex III superoxide-producing site inhibitor with neuroprotective effects that inhibits PC-3 cell proliferation in pyruvate-starved medium in a dose-dependent manner.
