of 5,6,7,8-tetrahydropyrido[3,4-b]pyrazine-based hydroxamic acids enabled us to establish the following structure-activity relationships; the existence of the hydroxamic acid, the sulfonamide, and the phenyl moieties are crucial for a potent HB-EGF shedding inhibitory activity, and the stereochemistry of the alpha carbon of hydroxamic acid is also important. In addition, from the comparison of their
HB-EGF脱落抑制剂有望成为治疗因角质形成细胞增殖引起的皮肤疾病的有效药物。为了发现新的HB-EGF脱落抑制剂并阐明它们的构效关系,使用5,6,7,8-四氢萘啶基异羟肟酸和5,6,7,8-四氢吡啶并[3,4-b]吡嗪-已经合成了基于羟基的异羟肟酸。在合成的化合物中,乙氧基乙氧基衍生物3o和甲氧基丙氧基衍生物3p表现出比CGS 27023A更有效的HB-EGF脱落抑制活性。5,6,7,8-四氢吡啶并[3,4-b]吡嗪基异羟肟酸的结构修饰使我们能够建立以下结构-活性关系;异羟肟酸,磺酰胺的存在 苯基部分对于有效的HB-EGF脱落抑制活性至关重要,异羟肟酸的α碳的立体化学也很重要。此外,通过比较它们的HB-EGF脱落抑制活性和MMPs抑制活性,我们发现,与MMP-1相比,负责HB-EGF脱落的酶的S1'口袋深。
