Abstract

The Paeonia suffruticosa ANDR. (P. suffruticosa) is commonly used in traditional medicine for various purposes. Suffruticosol A (Suf-A), isolated from P. suffruticosa, is a beneficial compound with antibiofilm, antivirulence, and anti-inflammatory properties. The aim of the present study was to investigate the biological effects of Suf-A on osteogenic processes in pre-osteoblasts. It was determined here in that Suf-A (>98.02%), isolated from P. suffruticosa, showed no cytotoxicity at 0.1-30 μM; however, it induced cytotoxicity at 50-100 μM in pre-osteoblasts. Suf-A increased osteogenic alkaline phosphatase activity and expression levels of noncollagenous proteins. Adhesion and trans-migration on the extracellular matrix were potentiated by Suf-A, but not by wound-healing migration. Suf-A did not affect autophagy or necroptosis during osteoblast differentiation. We found that Suf-A increased runt-related transcription factor 2 (RUNX2) levels and mineralized matrix formation. RUNX2 expression was mediated by Suf-A-induced BMP2-Smad1/5/8 and mitogen-activated protein kinase signaling, as demonstrated by Noggin, a BMP2 inhibitor. These results suggest that Suf-A is a potential natural osteogenic compound.

摘要

牡丹皮(Paeonia suffruticosa ANDR.)在传统医学中常用于多种用途。从牡丹皮中分离得到的牡丹酚 A(Suf-A)是一种有益的化合物,具有抗生物膜、抗病毒和抗炎特性。本研究旨在探讨 Suf-A 对成骨前体细胞成骨过程的生物学影响。结果表明,Suf-A(>98.02%)从牡丹皮中分离出来,在 0.1-30μM 时没有细胞毒性,但在 50-100μM 时对成骨前体细胞表现出细胞毒性。Suf-A 增加了成碱性磷酸酶活性和非胶原蛋白的表达水平。Suf-A 增强了细胞在细胞外基质上的黏附和迁移,但对创伤愈合迁移没有影响。Suf-A 在成骨细胞分化过程中不影响自噬或坏死。我们发现 Suf-A 增加了 runt 相关转录因子 2(RUNX2)的水平和矿化基质的形成。BMP2 抑制剂 Noggin 表明,Suf-A 通过诱导 BMP2-Smad1/5/8 和丝裂原活化蛋白激酶信号通路来介导 RUNX2 的表达。这些结果表明 Suf-A 是一种有潜力的天然成骨化合物。
