  studies showed that Comp-43 reduces mHTT levels by targeting GPR52 and promotes survival of mouse primary striatal neurons. Moreover, in vivo study showed that Comp-43 not only reduces mHTT levels but also rescues HD-related phenotypes in HdhQ140 mice. Taken together, our study confirms that inhibition of GPR52 is a promising strategy for HD therapy, and the GPR52 antagonist Comp-43 might serve as a lead

  GPR52是一种孤儿G蛋白偶联受体（GPCR），最近被认为是亨廷顿氏病（HD）（一种无法治愈的单基因神经退行性疾病）的潜在药物靶标。在这项研究中，我们发现GPR52的纹状体敲低可降低成年HDhQ140小鼠的mHTT水平，从而将GPR52确认为HD靶标。此外，通过结构-活性关系（SAR）研究，我们发现了一种高效且特异的GPR52拮抗剂Comp- 43，IC 50值为0.63μM 。进一步的研究表明，Comp- 43通过靶向GPR52降低mHTT水平，并促进了小鼠原代纹状体神经元的存活。此外，体内研究表明Comp- 43不仅降低了mHTT水平，而且还挽救了HDhQ140小鼠的HD相关表型。两者合计，我们的研究证实，抑制GPR52是HD治疗的一种有前途的策略，而GPR52拮抗剂Comp- 43可能充当进一步研究的先导化合物。

  report the first regioselective route to C3-hydroxyarylated pyrazoles obtained through reaction of pyrazole N-oxides with arynes using mild conditions. Importantly, this method does not require the C4 and C5 positions of the pyrazole to be functionalized to observe regioselectivity. Using this method, we completed the synthesis of a recently reported JAK 1/2 inhibitor. Our synthesis produces the desired
