TD-198946
CAS No. : 364762-86-7
MCE 国际站:TD-198946
产品活性:TD-198946是一种噻吩并唑衍生物。它是一种高效的软骨形成剂。
研究领域:Others
作用靶点:Others
In Vitro: TD-198946 is a potent chondrogenic agent. TD-198946 strongly induces chondrogenic differentiation without promoting hypertrophy in cell and metatarsal organ cultures. TD-198946 induces stronger Col2a1 promoter activity than insulin in ATDC5 cells. In C3H10T1/2 cells, ATDC5 cells and primary mouse chondrocytes, TD-198946 dose-dependently stimulates endogenous expression of the chondrocyte markers Col2a1 and Acan, with maximum effects around 1-10 μM.
In Vivo: When administered directly into the joint space, TD-198946 successfully prevents and repaires degeneration of the articular cartilage. TD-198946 exerts its effect through the regulation of Runx1 expression, which is downregulated in both mouse and human OA cartilage compared with normal tissue. TD-198946 has disease-modifying effects on progressed osteoarthritis. TD-198946 may prevent the progression of osteoarthritis by acting on the remaining chondrocytes rather than repairing damaged cartilage, it may be most effective as a therapeutic during the early or middle stages of osteoarthritis, before the articular cartilage is fully eroded. Cartilaginous cell-sheets are generated by culturing mouse and canine costal chondrocytes and human mesenchymal stem cells with TD-198946 on temperature-responsive dishes. The transplanted cell-sheets are then successfully used to promote the reconstruction of permanent cartilage, with no evidence of chondrocyte hypertrophy in the knee articular cartilage defects created in mice and canines.

文献和实验可引起移植排斥反应。此外,免疫球蛋白分子上存在的Gm、Am、Km标记均属异型抗原,可用以鉴别IgG、IgA及K轻链的异型。 在不同种属动物组织间也可发现有共同抗原,称这种抗原为异嗜性抗原。Forssman首先发现这种抗原,故亦称之为Forssman抗原。即这种抗原无种属特异性,它可共同存于人、不同种动物与微生物之间,因此它与疾病的发病学和诊断有一定意义。 目前已发现多种异嗜性抗原,如大肠杆轿O86含有人的B血型物质,肺炎球菌14型含有人A血型物质,它们与人血型抗体的产生
