Galantide, a non-specific galanin receptor antagonist, is a peptide consisting of fragments of galanin and substance P. Galantide recognizes two classes of galanin binding sites (KD<0.1 nM and ~6 nM) in the rat hypothalamus. Galantide dose dependently (IC50=1.0 nM) antagonizes the galanin-mediated inhibition of the glucose-induced insulin secretion from mouse pancreatic islets. Galantide appears to bind to a single population of SP receptors (KD~40 nM).

Fleroxacin is a broad-spectrum antimicrobial fluoroquinolone. It strongly inhibits the DNA-supercoiling activity of DNA gyrase.

GRP-60367 is the first small molecule rabies virus (RABV) entry inhibitor, which has nanomolar effect on some RABV strains.Grp-60367 inhibits the entry of a subset of the RABV strain.Grp-60367 showed the specificity and effective anti-RABV activity of the scaffold. In the dose-response analysis, the EC50s range from 2 to 52 nM in different host cell lines.
