半岛bd体育手机客户端 名称
L-Buthionine sulfoximine
L-BSO
半岛bd体育手机客户端 介绍
L-Buthionine-(S,R)-sulfoximine 是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1.9 μM、8.6 μM 和29 μM。
生物活性

L-Buthionine-(S,R)-sulfoximine is a cell-permeable, potent, fast acting and irreversible inhibitor ofg-glutamylcysteine synthetaseand depletes cellular glutathione levels. TheIC50value of L-Buthionine-(S,R)-sulfoximine on melanoma, breast and ovarian tumor specimens are 1.9 μM, 8.6 μM, and 29 μM, respectively.

IC50& Target

γ-glutamylcysteine synthetase[1].

体外研究
(In Vitro)

L-Buthionine-(S,R)-sulfoximine (BSO: 50 μM) 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 g-glutamylcysteine synthetase, an essential enzyme for the synthesis of glutathione (GSH)[2].
L-Buthionine-(S,R)-sulfoximine (BSO) induces ferroptosis in cancer cells[3].

体内研究
(In Vivo)

BSO causes an elevated frequency of DNA deletions during mouse development. BSO treatment reduced GSH concentration in mouse fetuses by 55% and 70% at 2 mM and 20 mM BSO doses, respectively, compared to untreated mice. Co-treatment with 2 mM BSO and 20 mM NAC depleted GSH to a similar extent as 2 mM 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[2].
