生物活性

SID 26681509 quarterhydrate is a potent, reversible, competitive, and selective inhibitor of human cathepsin L with an IC50 of 56 nM. SID 26681509 quarterhydrate inhibits in vitro propagation of malaria parasite Plasmodium falciparum and inhibits Leishmania major with IC50s of 15.4 μM and 12.5 μM, respectively. SID 26681509 quarterhydrate shows no inhibitory activity against cathepsin G[1].

IC50 & Target

IC50: 56 nM (Human cathepsin L), 0.5 μM (Cathepsin V), 15.4 μM (Plasmodium falciparum), 12.5 μM (Leishmania major)[1]

体外研究
(In Vitro)

After a 4 hr preincubation with cathepsin L, SID 26681509 becomes more potent, demonstrating an IC50 of 1.0 nM. SID 26681509 is determined to be a slow-binding and slowly reversible competitive inhibitor. Through a transient kinetic analysis for single-step reversibility, inhibition rate constants are kon = 24,000 M-1s-1 and koff = 2.2 × 10-5 s-1 (Ki = 0.89 nM). Molecular docking studies are undertaken using the experimentally-derived X-ray crystal structure of papain/CLIK-148[1].
SID 26681509 inhibits papain and cathepsins B, K, S, and V with IC50 values determined after one hour ranging from 618 nM to 8.442 μM. SID 26681509 shows no inhibitory activity against the serine protease cathepsin G[1].
SID 26681509 inhibits cathepsin V activity with an IC50 value of 0.5 μM. SID 26681509 (1-30 μM) blocks high-mobility group box 1 (HMGB1)-induced TNF-α production dose dependently without altering cell viability[2].
