4 nitroquinoline 1 oxide

4-Nitroquinoline 1-oxide (4-NQO) 是一种化学致癌物，可通过形成大量嘌呤加合物来诱导细菌、真菌和动物的突变。

Milbemycin A4 oxime is a derivative of milbemycin A4 and a component of milbemycin oxime , compounds that both have insecticidal and nematocidal activity. Milbemycin A4 oxime (0.05 mg kg) reduces the number of microfilariae of the heartworm D. immitis in naturally infested dogs. It inhibits the growth of clinical isolates of C. glabrata with MIC80 values ranging from 16 to greater than 32 μg ml. Milbemycin A4 oxime (2.5 μg ml) blocks efflux of fluconazole from a clinical isolate of C. glabrata, but not from a strain lacking the efflux pumps CgCDR1 and PDH1, and reduces the MICs of fluconazole and 4-nitroquinoline 1-oxide in wild-type C. glabrata. It enhances adriamycin-induced inhibition of cell growth, as well as increases the intracellular accumulation of adriamycin and the P-glycoprotein substrate rhodamine 123 , in adriamycin-resistant, but not -sensitive, MCF-7 breast cancer cells in a concentration-dependent manner.

Deacetylasperulosidic Acid 是海巴戟果实的主要植物化学成分。它能够防止体外 4-硝基喹啉1-氧化物诱导的 DNA 损伤，抑制 IL-2的产生以及自然杀伤细胞的活化。它具有抗原活性，抑制仓鼠卵巢细胞和小鼠中染色体畸变的诱导。它可增加超氧化物歧化酶活性，从而具有抗氧化活性。
