Z-Asp-CH2-DCB 是一种不可逆的广谱 caspase 抑制剂，Z-Asp-CH2-DCB 也能抑制具有 caspase 样活性的蛋白酶。Z-D-CH2-DCB 并以剂量依赖的方式阻断 PBMC 细胞中的金黄色葡萄球菌肠毒素 B (SEB) 刺激的 IL-1β、TNF-α、IL-6 和 IFN-γ 的产生，和降低 SEB-1 刺激的 T 细胞增殖。Z-Asp-CH2-DCB 可预防 SU5416 诱导的间隔细胞凋亡和肺气肿的发生。
Z-Asp-CH2-DCB (10-100 μM) blocks the production of IL-1β, TNF-α, IL-6, and IFN-γ in SEB-stimulated (200 ng; 16 hours) PBMC in a dose-dependent manner. The production of the chemokines MCP-1, MIP-1α, and MIP-1β was also suppresses. The inhibitory effect of Z-Asp-CH2-DCB on TSST-1-activated PBMC is similar, reducing IL-1β, IL-6, TNF-α, IFN-γ, MCP-1, MIP-1α, and MIP-1β to 10, 36, 25, 10, 11, 25, and 30%, respectively, of levels in untreated cells.
Z-Asp-CH2-DCB (10-100 μM; 48 hours) inhibits T-cell proliferation in PBMC stimulated with 200 ng of SEB/ml .
