noncytotoxic

JAK3-IN-11 (Compound 12) exhibits potent, noncytotoxic, irreversible, orally active JAK3 inhibitory activity (IC50 = 1.7 nM) with an excellent selectivity profile (>588-fold compared to other JAK isoforms), covalently binds to the ATP-binding pocket in JAK3. JAK3-IN-11 strongly inhibits JAK3-dependent signaling and T-cell proliferation which is a promising tool for studying autoimmune diseases [1].

INF39 is a noncytotoxic and irreversible NLRP3 inhibitor.

Hexa-D-arginine is an inhibitor of furin,blocks the activation of Pseudomonas aeruginosa exotoxin A in vivo.

LIMK1 inhibitor BMS-4 is a compound targeting LIM Kinase (LIMK) 1 2, specifically inhibiting the phosphorylation of its substrate cofilin, while remaining noncytotoxic on A549 cells.

PD-128763 is a selective inhibitor of poly(ADP-ribose) polymerase. PD-128763 has an IC50 value against the purified enzyme approximately 50X lower than 3-aminobenzamide (3-AB), a widely used specific inhibitor of the enzyme. Exposure of exponentially growing cells to a noncytotoxic concentration (0.5 mM) of PD 128763 for 2 h immediately following X irradiation increased their radiation sensitivity, modifying both the shoulder and the slope of the survival curve. When recovery from sublethal damage and potentially lethal damage was examined in exponential and plateau-phase cells, respectively, postirradiation incubation with 0.5 mM PD 128763 was found not only to inhibit both these processes fully, but also to enhance further the level of radiation-induced cell killing. This is in contrast to the slight effect seen with the less potent inhibitor, 3-AB. The results presented suggest that the mechanism of radiosensitization by PD 128763 is related to the potent inhibition of pol......
