| 产品描述: | M-31850 is a potent, selective and competitive β-hexosaminidase (Hex) inhibitor with IC50s of 6.0 µM and 3.1 µM for human HexA and human HexB, respectively. M-31850 also competitively inhibits β-N-acetyl-D-hexosaminidase OfHex2 with a Ki of 2.5 μM |
| 靶点: |
IC50: 6.0 µM (human HexA) and 3.1 µM (human HexB). Ki: 2.5 μM (OfHex2) |
| 体外研究: |
M-31850 shows some activity towards Jack Bean Hex (JBHex) and bacterial Hex from Streptomyces plicatus (SpHex) (IC50 of 280 µM and >500 µM for JBHex and SpHex, respectively).
M-31850 produces a dose dependent increase in MUG hydrolysis (Hex S levels) in lysates from treated infantile Sandhoff disease (ISD) cells.
M-31850 increases the half-life of the mutant Hex A from Adult forms of Tay-Sachs (ATSD) cells more than two-fold at 44° C, relative to the enzyme heated in the presence of DMSO. M-31850 acts as a classic competitive inhibitor of Hex (Km increases and Vmax is unaffected by increasing amounts of M-31850), with a Ki of 0.8 μM. |
| 体内研究: |
M-31850 显示出对 Jack Bean Hex (JBHex) 和来自 Streptomyces plicatus (SpHex) 的细菌 Hex 的一些活性 (JBHex 和 SpHex 的 IC50 分别为 280 μM 和 >500 μM)。 M-31850 在经处理的婴儿桑德霍夫病 (ISD) 细胞的裂解物中产生 Mug 水解 (Hex S 水平) 的剂量依赖性增加。 M-31850 将 Tay-Sachs (ATSD) 细胞成体形式的突变体 Hex A 的半衰期在 44° C 下延长两倍以上,相对于在DMSO 的存在。M-31850 作为 Hex 的经典竞争性抑制剂 (Km 增加,Vmax 不受 M-31850 增加量的影响),Ki 0.8 μM。 |
