interactive cycles of design, synthesis and screening, accompanied by computational evaluation and optimization. Two MMP3Is, e(I) and l(II), were selected because of their effective inhibitory activity (3.2 and 10.2 µM, respectively) and water solubility. Both MMPIs showed a broad range of inhibitory effects against almost all the MMPs tested. In an in vitromodel of inflammatory OA, e(I) was the most effective
自 2007 年以来,金属蛋白酶 (MMP) 被认为是治疗骨关节炎 (OA) 的潜在目标,其主要致病事件是关节软骨的广泛退化。MMP3 是一种对这些退行性变化至关重要的酶。然而,在 MMPs 抑制剂 (MMPIs) 的临床试验期间,选择性、低生物利用度和不良代谢特征的问题导致有限的有益效果,因此没有理由进一步开展临床研究。在之前的一项工作中,一种新的透明质酸 (HA) 烷基衍生物 HYADD4®,之前被批准用于膝关节 OA 的关节内治疗,在体外和体内进行了研究作为 MMP3I。分子模拟研究证实了这种 HA 衍生物的烷基侧链与 MMP3 的额外 S1' 口袋之间的相互作用。然而,HYADD4® 的高分子量和极性 HA 骨架意味着高去溶剂化能量成本,这可能会降低其抑制效力。在这项研究中,通过设计、合成和筛选的交互循环,以及计算评估和优化,开发了一类基于小肽主链 (CGV) 化学衍生的新型 MMP3Is。选择了两种

This invention relates generally to olefin metathesis, and more particularly relates to the ring-opening, ring insertion cross-metathesis of cyclic olefins with internal olefins such as seed oils and the like. In one embodiment, a method is provided for carrying out a catalytic ring-opening cross-metathesis reaction, comprising contacting at least one olefinic substrate with at least one cyclic olefin as a cross metathesis partner, in the presence of a ruthenium alkylidene olefin metathesis catalyst under conditions effective to allow ring insertion cross metathesis whereby the cyclic olefin is simultaneously opened and inserted into the olefinic substrate. The invention has utility in the fields of catalysis, organic synthesis, and industrial chemistry.
