1-Methyladenine is a methylated adenine nucleotide and a product of alkylation damage in DNA[1-2]. 1-Methyladenine is used in research related to DNA damage and developmental biology[3-4].
In vitro, diploid yeast Saccharomyces cerevisiae BZ34 (adenine auxotroph) was treated with 1-Methyladenine (20mg/L) for 24–48 hours. 1-Methyladenine completely inhibited cell growth, but did not cause cell death or induce cytotoxic or genotoxic effects[5]. Starfish oocytes were treated with 1-Methyladenine (1µM) for 3–10 minutes. 1-Methyladenine induced germinal vesicle breakdown (GVBD). When starfish oocytes were co-treated with 1-Methyladenine and the calcium ionophore A23187 (20µM), the formation of the fertilization envelope was completely suppressed, and the oocyte’s ability to form a fertilization envelope in response to elevated calcium was blocked[6].

1-Methyladenine是一种甲基化的腺嘌呤核苷酸，是DNA中烷基化损伤的产物[1-2]。1-Methyladenine可用于DNA损伤、发育生物学的相关研究[3-4]。
在体外，1-Methyladenine（20mg/L）处理二倍体酵母Saccharomyces cerevisiae BZ34（腺嘌呤营养缺陷型）24-48小时。1-Methyladenine完全抑制细胞生长，但不导致细胞死亡且未诱发细胞毒性或遗传毒性效应[5]。1-Methyladenine（1μM）处理海星卵母细胞3-10分钟。1-Methyladenine可诱导胚泡破裂 （GVBD）。1-Methyladenine与钙离子载体A23187（20μM）共处理海星卵母细胞会完全抑制受精膜的形成，同时阻断了卵母细胞响应钙升高形成受精膜的能力[6]。
| Cell experiment [1]: | |
Cell lines | Diploid yeast Saccharomyces cerevisiae BZ34 (adenine auxotroph) |
Preparation Method | Yeast cells from stationary phase culture were washed and resuspended in synthetic complete (SC) medium in which adenine was replaced by 1-Methyladenine (20mg/L). Cultures were incubated in a shaker water bath at 30°C. Growth was monitored at 24 and 48 hours. |
Reaction Conditions | 20mg/L; 24-48h |
Applications | 1-Methyladenine completely inhibited cell growth (without causing cell death) and did not induce cytotoxic or genotoxic effects, as measured by the frequency of gene conversion and reverse mutation. |
