生物活性

Fluchloralin is a dinitroaniline herbicide that effectively controls annual gramineous and broadleaf weeds primarily by inhibiting tubulin synthesis and cell division. Fluchloralin exhibits cytotoxicity and genotoxicity, and promotes cell apoptosis by activating apoptotic signaling proteins, forming DNA ladder bands, inducing cell shrinkage and nuclear fragmentation[1][2].

体外研究
(In Vitro)

Fluchloralin (5-20 μg/mL; 24-72 h) 在 CHO 和 MEF 细胞中表现出剂量和时间依赖性的细胞毒性[2]
Fluchloralin (2.5-20.0 μg/mL; 4-12 h) 会在 CHO 细胞中诱导具有统计学意义、时间依赖性的染色体畸变[2]
Fluchloralin (1.0-20.0 μg/mL; 12 h) 使 CHO 细胞的姐妹染色单体交换水平产生具有统计学意义的升高[2]
Fluchloralin (5-20 μg/mL; 30 h) 对同步化 MEF 细胞的 DNA 合成产生剂量依赖性抑制作用,且不影响胸苷转运[2]
Fluchloralin (5-20 μg/mL; 6 h) 可使同步化 MEF 细胞在处理后 12 h 时的 DNA 合成水平下降近 50%,且不影响胸苷转运[2]
Fluchloralin (5-20 μg/mL; 24-72 h) 可诱导 CHO 细胞发生细胞凋亡,DNA 梯状条带形成及典型的细胞核变化可证明这一点[2]

Cell Cytotoxicity Assay[2]

Cell Line: Chinese hamster ovary (CHO) cells, mouse embryo fibroblast (MEF) cells
Concentration: 5, 10, 15 and 20 μg/mL
Incubation Time: 24 h; 48 h; 72 h
Result: Induced a dose-dependent decrease in cell viability in both cell lines, with greater toxicity observed in CHO cells than MEF cells.
Reduced viability to 50% in CHO cells treated with 20 μg/mL for 72 h.
Reduced viability to 50% in MEF cells treated with 20 μg/mL for 72 h.

Apoptosis Analysis[2]

Cell Line: Chinese hamster ovary (CHO) cells
Concentration: 5, 10 and 20 μg/mL
Incubation Time: 24 h; 48 h; 72 h
Result: Induced a characteristic DNA ladder pattern in agarose gels of DNA from treated CHO cells.
Revealed apoptotic features including cell shrinkage and nuclear fragmentation via microscopic observation.
Induced apoptosis at 20 μg/mL after 72 h of treatment.
体内研究
(In Vivo)

Fluchloralin (0.5-2 mg/L;水体浸泡;共 4 天) 对斑马鱼胚胎具有剂量依赖性发育毒性,包括存活率降低 (LC50 = 2.004 mg/L)、形态缺陷、神经毒性、心脏毒性、肝脏损伤及脑部细胞凋亡增加[1]

Animal Model: Transgenic zebrafish (olig2:dsRed, cmlc2:dsRed, lfabp:dsRed;elastase:GFP); wild-type zebrafish (reared at 26-28.5 °C on a 13 h light/11 h dark cycle, 8 hours post-fertilization)[1]
Dosage: 0.5 mg/L; 1 mg/L; 2 mg/L
Administration: aquatic immersion; daily; 96 hours
Result: Significantly increased the number of apoptotic cells in the brain region of zebrafish.
Caused developmental toxicity to multiple organs (nervous system, heart, liver, pancreas) in zebrafish embryos.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
