| 体外研究： | KGP94 (10 or 20 μM, 24 h) reduces expression of M2 (macrophage) markers (Arginase-1 and CD206) and cells invasion of primary bone marrow-derived macrophages or Raw264.7. KGP94 (25 μM, 24 h) impairs the incasive capacities of both prostate and breat cancer cells by 53% and 88%, respectively. KGP94 (25 μM, 24 h) suppresses secreted CTSL activity by 94% and 92% in PC-3ML and MDA-MB-231, repsectively. |
