noncytotoxic

Hexa-D-arginine 是稳定的furin 抑制剂，能够作用于 furin (Ki:106 nM)、PACE4 (Ki:580 nM)、PC1 (Ki:13.2 nM)。它在体外和体内均可阻断假单胞菌外毒素 A 和炭疽毒素的毒性。

JAK3- in -11 (Compound 12) 是表现出强效的、无细胞毒性、不可逆、口服活性的JAK3抑制活性，IC50值为1.7 nM，具有出色的选择性(高于其他 JAK3 亚型的588倍)，共价结合到 JAK3 的 ATP-binding pocket。 JAK3-IN-11 强烈抑制 JAK3 依赖的信号转导和T 细胞增殖，是研究自身免疫性疾病的有效工具。

INF39 是无细胞毒性的NLRP3不可逆抑制剂。

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......
