生物活性
产品描述 |
一种具有细胞渗透性的、有效的、快速起效的、不可逆的 G-谷氨酸半胱氨酸合成酶 (γ-glutamylcysteine synthetase) 抑制剂,可降低细胞内谷胱甘肽的水平,其对黑色素瘤、乳腺卵巢癌标本的 IC50 值分别为1.9μM、8.6μM 和29μM。 |
靶点 |
γ-glutamylcysteine synthetase |
体外研究 |
L-Buthionine-(S,R)-sulfoximine (BSO: 50μM) treatment for 48 hr results in a 95% decrease in ZAZ and M14 melanoma cell line GSH levels, and a 60% decrease in GST enzyme activity. GST-π protein and mRNA levels are significantly reduced in both cell lines[1]. L-Buthionine-(S,R)-sulfoximine (BSO) induces oxidative stress in a cell by irreversibly inhibiting gglutamylcysteine synthetase, an essential enzyme for the synthesis of glutathione (GSH). L-Buthionine-(S,R)-sulfoximine (BSO) induces ferroptosis in cancer cells |
体内研究 |
BSO causes an elevated frequency of DNA deletions during mouse development. BSO treatment reduced GSH concentration in mouse fetuses by 55% and 70% at 2mM and 20mM BSO doses, respectively, compared to untreated mice. Co-treatment with 2mM BSO and 20mM NAC depleted GSH to a similar extent as 2mM BSO, consistent with the function of BSO to inhibit the g-GCS enzyme indispensable for GSH synthesis. Like GSH, cysteine levels dropped following BSO treatment. |
本计算器可帮助您计算出特定溶液中溶质的质量、溶液浓度和体积之间的关系,公式为:
质量 (g) = 浓度 (mol/L) x 体积 (L) x 分子量 (g/mol)
