常見問題列表
生物活性
4-Diethylaminobenzaldehyde 是一種可逆的醛脫氫酶 (ALDHs) 抑制劑，對 ALDH1 的 Ki 為 4 nM。4-Diethylaminobenzaldehyde 具有較強的抗雄激素作用 (IC50= 1.71 μM)。體外研究
4-Diethylaminobenzaldehyde (DEAB) is reversible competitive inhibitor of ALDH1 (competitive with the aldehyde substrate) with a K
i
value of 4 nM, and irreversibly inactivates ALDH7A1 via formation of a stable, covalent acyl-enzyme species.
The Temozolomide (TMZ)-resistant cell line LN18 is treated with a combination of TMZ and 4-Diethylaminobenzaldehyde for 10 days. As indicated by colony formation assay, the clonogenic capacity of LN18 cells exposed to TMZ in combination with 4-Diethylaminobenzaldehyde (DEAB) is significantly attenuated.
