Apramycin(Nebramycin II) is an aminoglycoside antibiotic used in veterinary medicine. IC50 value:Target: Apramycin stands out among aminoglycosides for its mechanism of action which is based on blocking translocation and its ability to bind also to the eukaryotic decoding site despite differences in key residues required for apramycin recognition by the bacterial target. The drug binds in the deep groove of the RNA which forms a continuously stacked helix comprising non-canonical C.A and G.A base pairs and a bulged-out adenine. The binding mode of apramycin at the human decoding-site RNA is distinct from aminoglycoside recognition of the bacterial target, suggesting a molecular basis for the actions of apramycin in eukaryotes and bacteria.

Urocortin II, a neuropeptide hormone within the corticotropin-releasing factor (CRF) family—which comprises mammalian CRF, urocortin I, urocortin III, frog sauvagine, and piscine urotensin I—displays 34, 43, and 37-40% sequence homology with rat and human CRF, human urocortin I, and human urocortin III, respectively. This compound enhances rabbit ventricular myocyte shortening and relaxation in both a time- and concentration-dependent manner. In vivo studies reveal that urocortin II lowers arterial blood pressure in both normotensive and spontaneously hypertensive rats through peripheral CRF2 receptor agonism, inducing dose-dependent tachycardia and hypotension at doses of 3 and 30 pmol/kg. Additionally, it mitigates the visceral pain response to colorectal distension at 10 and 20 μg/kg in conscious rats and delays gastric emptying in mice.
