p388/adr

Zosuquidar trihydrochloride (LY-335979 trihydrochloride) 是一种P-糖蛋白抑制剂，Ki 值为 59 nM。

Dihydrocytochalasin B (H2CB) 是一种细胞分裂抑制剂，抑制胞质分裂并改变细胞的形态,破坏 Swiss 3T3 小鼠成纤维细胞的肌动蛋白结构，抑制血清生长因子在静止培养物中刺激 DNA 合成的能力,瓦解肌动蛋白细胞结构并抑制 3T3 细胞中 DNA 合成的启动。低剂量的 H2CB 会导致细胞变圆和肌动蛋白微丝束的丢失。

A 30312 is a fused indole, which overcomes multidrug resistance in P388 Adr cells in vitro. It potentiates the cytotoxicity of the antitumor drugs Adriamycin, vincristine and vinblastine in multidrug-resistant cells with no effect on drug-sensitive parent P388 cells.

FD-211 is a δ lactone originally isolated from M. lutea with anticancer activity.1 It is cytotoxic to adriamycin-susceptible P388, T-24, HeLa, A549, and HL-60 cancer cells (IC50s = 4, 0.5, 1, 1, and 0.2 μg/ml, respectively), as well as adriamycin-resistant HL-60/ADR cells (IC50 = 0.1 μg/ml). FD-211 also inhibits DNA, RNA, and protein synthesis in HeLa cells (IC50 = 1.25 μg/ml for all). |1. Nozawa, O., Okazaki, T., Sakai, N., et al. A novel bioactive δ lactone FD-211.
