RNASE L Inhibitor

RNase L-IN-1 is a RNase L inhibitor with an IC₅₀ of 15.9 μM. RNase L-IN-1 binds to the ATP-binding pocket of RNase L, and inhibits ribosomal RNA cleavage. RNase L-IN-1 can be used for the research of RNase L-associated cellular processes.

2-5A TEA (2′,5′-ApApA TEA) is a 5'-triphosphorylated (2',5') oligoadenylate. When covalently linked to an antisense molecule complementary to the target sequence, 2-5A TEA activates RNase L, which subsequently degrades the target RNA bound to the 2-5A TEA chimera. 2-5A TEA can be used in research related to respiratory syncytial virus infection, colorectal adenocarcinoma and melanoma.

2-5A pentasodium solution (100 mM) (2′,5′-ApApA pentasodium solution (100 mM)) is a 5'-triphosphorylated (2',5') oligoadenylate. When covalently linked to an antisense molecule complementary to the target sequence, 2-5A pentasodium solution (100 mM) activates RNase L, which subsequently degrades the target RNA bound to the 2-5A pentasodium solution (100 mM) chimera. 2-5A pentasodium solution (100 mM) can be used in research related to respiratory syncytial virus infection, colorectal adenocarcinoma and melanoma.

NCI-65828 (N-65828) sodium is a cell-permeable small molecule inhibitor. NCI-65828 inhibits the ribonuclease activity of human angiogenin and zebrafish Rnasel-1/3, as well as the activity of Mycobacterium tuberculosis AccD5 and its holoenzyme complex. NCI-65828 induces neuronal developmental defects, impairs vascular development, inhibits neurite outgrowth, and reduces protein synthesis in stem cells and neural progenitor cells, but shows no significant growth inhibitory effect on various human tumor cell lines. NCI-65828 is primarily used to study the role of angiogenin-like ribonucleases in neural and vascular development, to establish effect models of ALS-related angiogenin mutants, and in research related to amyotrophic lateral sclerosis, frontotemporal dementia, and tuberculosis.

GS-646089 is a broad-spectrum antiviral nucleoside analog that exhibits significant inhibitory activity against respiratory syncytial virus (RSV), human metapneumovirus (hMPV), rhinovirus (enterovirus) and enteroviruses. The IC₅₀ of GS-646089 targeting RNA-dependent RNA polymerase (RdRp) ranges from 43 to 46 nM. GS-646089 blocks viral replication by being converted into a triphosphate metabolite intracellularly, which competes with ATP for incorporation into nascent RNA strands and acts as an immediate chain terminator. GS-646089 is the parent compound of the double prodrug GS-7682 (HY-161877), and is used in studies of acute respiratory viral infections and infections caused by related pathogens.
