further explore the development of noviomimetics and evaluate their efficacy using a luciferase refolding assay, immunoblot analysis, a c-jun assay, and an assay measuring mitochondrial bioenergetics. These new noviomimetics were designed and synthesized and found to induce Hsp70 and improve biological activity. Noviomimetics 39e and 40a were found to induce Hsp70 and exhibit promising effects in cellular
热休克蛋白90(Hsp90)是一种正在研究中的用于治疗癌症和神经退行性疾病的伴侣蛋白。衍生自新霉素(novologues)的神经保护性Hsp90 C-末端抑制剂包括KU-32和KU-596。这些创新分子调节分子伴侣,并导致热休克蛋白70(Hsp70)的诱导。与酚醛清毒剂KU-596和KU-32相比,“拟诺维制剂”用一个简单的环己基部分取代了合成复杂的酚醛新糖,以保持生物学功效。在这项研究中,我们进一步探索仿拟药物的开发,并使用荧光素酶复性测定,免疫印迹分析,c-jun测定和测量线粒体生物能的测定来评估其功效。这些新的仿拟药物是经过设计和合成的,可诱导Hsp70并改善其生物学活性。仿拟药物发现39e和40a在细胞测定中诱导Hsp70并显示出有希望的作用。
