KP-S54

KP-S54 is an antiviral agent derived from GS-441524 (HY-103586) and also a SARS-CoV-2 Mac1 and MERS-CoV Mac1 inhibitor. KP-S54 blocks interferon-induced reversal of ADP-ribosylation, with an IC₅₀ value of 44 nM against SARS-CoV-2 and an IC₅₀ value of 91 nM against MERS-CoV. KP-S54 produced no detectable antiviral efficacy in a SARS-CoV-2-infected mouse model. KP-S54 can be used for research related to SARS-CoV and MERS-CoV infection.

Beschreibung

In Vitro

KP-S54 (compound 18c) exhibits inhibitory activity against recombinant SARS-CoV-2 Mac1 (IC₅₀ = 44 nM) and MERS-CoV Mac1 (IC₅₀ = 91 nM)^[1].
KP-S54 (1 μM) exhibited half-lives of 17, 41, and 35 min in mouse, rat, and human liver microsomes, respectively, with 32.8% remaining in mouse MLM after 15 min^[1].
KP-S54 (500 μM; 5 h) exhibited a PAMPA permeability of approximately 4.72 × 10^-6 cm/s^[1].

In Vivo

Viral Infection

KP‑S54 (compound 18c) (100 mg/kg; intraperitoneal injection, once daily, from 1 day before infection to day 6 after infection) produced no detectable antiviral efficacy in a SARS‑CoV‑2-infected mouse model^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
