產(chǎn)品描述:

色霉素A3Chromomycin A3,CMA3CAS7059-24-7,同義名Aburamycin b,由灰色鏈霉菌Streptomyces griseus)代謝純化所得的一種蒽醌抗生素,具有抗菌、抗真菌和抗腫瘤活性。常用作一種熒光DNA染料,非常適合用來篩查經(jīng)子染色質(zhì)存在的精蛋白缺乏(protamine deficiency)。在二價(jià)金屬離子存在的條件下,色霉素A3CMA3)通過與DNA特異性結(jié)合與可逆作用來阻斷大分子合成。另外,通過結(jié)合到DNA小溝,色霉素A3有效調(diào)控與DNA促旋酶的競(jìng)爭(zhēng)性抑制,從而顯著影響拓?fù)洚悩?gòu)酶II活性。CMA3對(duì)非小細(xì)胞性肺癌和宮近癌呈現(xiàn)體外細(xì)胞毒性,作用于HCC44A549,ME180 HeLa細(xì)胞的IC50s分別是1,42,6040nM。CMA3還能通過改善Sp1Sp3轉(zhuǎn)錄因子結(jié)合來抑制氧化應(yīng)激和DNA損傷誘導(dǎo)的神經(jīng)損傷。具體內(nèi)活性。

文獻(xiàn)1Esterhuizen AD et al. Chromatin packaging as an indicator of human sperm dysfunction. J Assist Reprod Genet. 2000 Oct;17(9):508-14. PMID: 11155324

體外研究:

樣本類型(Sample type):Semen Preparation

應(yīng)用目的(Purpose):Using CMA3 staining to determine quality chromatin packaging

實(shí)驗(yàn)方法(Assay):CMA3 staining thin smears were prepared, air dried, and ?xed in methanol/acetic acid 3:1 at room temperature for 20 min. The slides were air-dried and stained with 60–100µl CMA3 in a dark chamber for 20 min. Slides were then washed in McIlvaine buffer and mounted using Dabco. Two hundred spermatozoa were evaluated under a Nikon ?uorescent microscope.

體外研究:

樣本類型(Sample type):Semen aliquots

應(yīng)用目的(Purpose):Using CMA3 staining to assess the packaging quality of the chromatin in sperm

實(shí)驗(yàn)方法(Assay):The spermatozoa were washed again, fixed in methanol/glacial acetic acid (3:1) at 4℃ for 5 min and then spread on slides. For CMA3 staining, each slide was treated for 20 min with 100µl of CMA3 solution (0.25 mg/ml in McIlvaine buffer, pH 7.0, containing 10 mM MgCl2). The slides were then rinsed in buffer and mounted with buffered glycerol. Microscopic analysis of the slides was performed on a fluorescent Zeiss axioplane microscope with the appropriate filters.

體外研究:

細(xì)胞類型(Cell type):PC3 cells

藥物配制(Preparation):Chromomycin A3 was dissolved in ethanol as 1:1000 stock solution.

實(shí)驗(yàn)方法(Assay):PC3 cells were seeded at indicated densities in 12-well plates in triplicates and treated with DMSO, atorvastatin (10 μM), cyclohexamide (10 μg/ml) and chromomycin A3 (5 μM) or atorvastatin plus cyclohexamide or chromomycin A3. The cells were cultured for 2, 3 and 4 d, trypsinized, and counted by the cell counter Cellometer Auto T4.
