所述“室温”不是精确的温度值，是指10-30℃温度范围。
本发明中，“晶体”或“多晶型”指的是被所示的X射线衍射图表征所证实的。本领域技术人员能够理解，这里所讨论的理化性质可以被表征，其中的实验误差取决于仪器的条件、样品的准备和样品的纯度。特别是，本领域技术人员公知，X射线衍射图通常会随着仪器的条件而有所改变。特别需要指出的是，X射线衍射图的相对强度也可能随着实验条件的变化而变化，所以峰强度的顺序不能作为唯一或决定性因素。事实上，XRPD图谱中衍射峰的相对强度与晶体的择优取向有关，本文所示的峰强度为说明性而非用于绝对比较。另外，峰角度的实验误差通常在5％或更少，这些角度的误差也应该被考虑进去，通常允许有±0.2°的误差。另外，由于样品高度等实验因素的影响，会造成峰角度的整体偏移，通常允许一定的偏移。因而，本领域技术人员可以理解的是，本发明中一个晶型的X射线衍射图不必和这里所指的例子中的X射线衍射图完全一致，本文所述“XRPD图相同”并非指绝对相同，相同峰位置可相差±0.2°且峰强度允许一定可变性。任何具有和这些图谱中的特征峰相同或相似的图的晶型均属于本发明的范畴之内。本领域技术人员能够将本发明所列的图谱和一个未知晶型的图谱相比较，以证实这两组图谱反映的是相同还是不同的晶型。
“晶型”和“多晶型”以及其他相关词汇在本发明中指的是固体化合物在晶体结构中以特定的晶型状态存在。多晶型理化性质的不同可以体现在储存稳定性、可压缩性、密度、溶出速度等方面。在极端的情况下，溶解度或溶出速度的不同可以造成药物低效，甚至毒性。
在一些实施方案中，本发明的新晶型CS1、CS2、CS5和CS6是纯的、单一的，基本没有混合任何其他晶型。本发明中，“基本没有”当用来指新晶型时指这个晶型含有少于20％(重量)的其他晶型，尤其指少于10％(重量)的其他晶型，更指少于5％(重量)的其他晶型，更指少于1％(重量)的其他晶型。
需要说明的是，本发明中提及的数值及数值范围不应被狭隘地理解为数值或数值范围本身，本领域技术人员应当理解其可以根据具体技术环境的不同，在不背离本发明精神和原则的基础上围绕具体数值有所浮动，本发明中，这种本领域技术人员可预见的浮动范围多以术语“约”来表示。
本发明中所述“反溶剂”是指对式(I)化合物的不良溶剂，所述气固渗透法是指：将起始原料置于具有特定溶剂氛围的密闭环境中，起始原料不直接与溶剂接触，而是通过溶剂挥发扩散与起始原料间接接触制备得到新固体形态的方法。
本发明提供的晶型CS1、CS2、CS5和CS6具有下列优势：
(1)本发明提供的晶型与现有技术油状物相比，纯度显著提高。现有技术油状物的纯度仅为83.87％，而本发明的晶型纯度较高。在具体的实施例中，本发明提供的晶型纯度大于98％，在另一个具体的实施例中，本发明提供的晶型的纯度大于99％。本发明的晶型具有较强的杂质排除能力，且还可通过结晶工艺得到纯度更高的原料药，并且不容易出现溶剂残留的问题，使得样品残留溶剂容易达标并符合质量要求，适合药用；
(2)本发明提供的晶型引湿性低，能够克服高引湿性带来的弊端，如因吸水发生重量变化导致原料晶型组份含量不确定；且有利于药品的长期贮存，降低物料储存以及质量控制成本。本发明提供的晶型CS1、CS2和CS5在80％相对湿度条件下增重量分别为0.042％、0.101％和0.325％，引湿性低。本发明晶型CS1、CS2和CS5的低引湿性能够很好地对抗药物制剂和/或存储等过程中晶型不稳定以及由环境湿气等外来因素所引起的制剂不可加工等问题，有利于制剂制备中的准确定量和后期的运输和储存；
(3)本发明提供的晶型稳定性好，从而保证样品的质量标准一致可控，符合药物应用及制剂工艺中对晶型的苛刻要求。本发明的晶型CS1、CS2和CS5在25℃/60％相对湿度和/或40℃/75％相对湿度和/或60℃/75％相对湿度条件下至少可稳定放置1个月，优选的至少可稳定放置6个月，优选的至少可稳定放置一年。因此，本发明的晶型CS1、CS2和CS5具有良好的稳定性，有利于样品的保存和制剂的稳定；
(4)本发明提供的晶型溶解性良好，可降低给药剂量从而降低药品的副作用并提高药品的安全性，且在口服后不需要高剂量即可达到所需的治疗血药浓度，有利于药物在人体内的吸收，从而达到理想的药物生物利用度和药效，符合药用要求；
(5)本发明提供的晶型机械稳定性好，降低制剂制备时研磨或压片过程发生转晶的风险。本发明的晶型CS1、CS2、CS5和CS6具有高的研磨稳定性，制剂加工过程中常需要原料药的研磨粉碎，高的研磨稳定性能够减小制剂加工过程中发生原料药晶型结晶度改变和转晶的风险。
此外，本发明提供一种药用组合物，所述药用组合物包含治疗和/或预防有效量的本发明晶型CS1、CS2、CS5或CS6，以及至少一种药学上可接受的赋形剂。
进一步的，本发明提供GFT-505的晶型CS1、CS2、CS5或CS6在制备治疗非酒精性脂肪肝炎和/或II型糖尿病和/或血脂异常和/或动脉粥样硬化疾病的药物制剂中的用途。

实施例10：现有油状物和本发明晶型CS1、晶型CS2的纯度对比
采用HPLC测定根据现有技术制备得到的油状物、本发明的晶型CS1和本发明晶型CS2的纯度，结果如下表9所示。
表9
形态 油状物 晶型CS1 晶型CS2
纯度 83.87％ 99.25％ 99.56％
药物的纯度对于保证药物的疗效和安全性，防止药物不良反应的发生具有重要意义。现有油状物的杂质含量极高，会使药物含量明显偏低或活性降低；杂质含量高也会使毒副作用显著增加，因此不能作为原料药用于制剂的制备。
本发明晶型的纯度较高，利于工业化生产。本发明的晶型具有较强的杂质排除能力，且还可通过结晶工艺得到纯度更高的原料药，并且不容易出现溶剂残留的问题，使得样品残留溶剂容易达标并符合质量要求，适合药用。

晶型CS2在80％相对湿度下平衡后，相较于30％的起始相对湿度，增重0.101％，几乎无引湿性，方便长期贮存放置，其DVS图如图19所示。此外，在DVS前后分别检测晶型CS2的XRPD图，结果如图20(上图为DVS前的XRPD图，下图为DVS后的XRPD图)所示，表明DVS前后晶型CS2没有发生变化。
晶型CS5在80％相对湿度下平衡后，增重0.325％，属于略有引湿性，其DVS图如图21所示。此外，在DVS前后分别检测晶型CS5的XRPD图，结果如图22(上图为DVS前的XRPD图，下图为DVS后的XRPD图)所示，表明在动态水分吸附实验前后晶型CS5没有变化。

有引湿性：引湿增重小于15％但不小于2％
略有引湿性：引湿增重小于2％但不小于0.2％
无或几乎无引湿性：引湿增重小于0.2％
实施例12：晶型CS1、CS2和CS5的稳定性研究

药物的稳定性至关重要，尤其在市售有效期内，保持较好的稳定性能够减少药物由于晶型变化而导致药物溶出速率及生物利度改变的风险，对保证药物疗效和安全性，防止药物不良反应的发生具有重要意义。更稳定的晶型在结晶工艺过程中更加可控，不容易出现混晶，且在制剂工艺及储存过程中，不容易转变成其它晶型，从而保证样品的质量标准一致可控，并确保制剂产品的溶出曲线不会随着储存的时间变化而发生改变。
结果表明，本发明晶型CS1、CS2和CS5具有良好的稳定性，符合药物应用中及制剂工艺中对晶型可能的苛刻要求。
实施例13：晶型CS1、CS2、CS5和CS6的动态溶解度研究
为测试本发明晶型CS1、CS2、CS5和CS6的溶解性，发明人做了如下实验：
将本发明中的晶型CS1、CS2和CS5样品分别用pH1.8SGF(模拟胃液),pH5.0FeSSIF(模拟进食状态下人工肠液)，pH6.5FaSSIF(模拟空腹状态下人工肠液)和H 2O配制成饱和溶液，在1个小时、4个小时后和24个小时后采用高效液相色谱测定饱和溶液中样品的含量。将本发明中的晶型CS6样品分别用pH1.8SGF(模拟胃液),pH5.0FeSSIF(模拟进食状态下人工肠液)和pH6.5FaSSIF(模拟空腹状态下人工肠液)配制成饱和溶液，在1个小时、4个小时后和24个小时后采用高效液相色谱测定饱和溶液中样品的含量。晶型CS1的溶解度实验结果如表13所示，晶型CS2的溶解度实验结果如表14所示，晶型CS5的溶解度实验结果如表15所示，晶型CS6的溶解度实验结果如表16所示。

溶解度是药物的关键性质之一，直接影响药物在人体内的吸收。不同晶型药物的溶解度可能会存在明显差异，体内吸收动态也会发生变化，造成生物利用度的差异，最终影响到药物的临床安全性和疗效。
从以上数据可知，本发明的晶型CS1、CS2和CS5在SGF、FaSSIF、FeSSIF和水中的溶解度，以及本发明晶型CS6在SGF、FaSSIF和FeSSIF的溶解度符合药用要求，尤其是在FaSSIF(模拟空腹状态下人工肠液)和FeSSIF(模拟进食状态下人工肠液)中的溶解度较高。本发明晶型CS1、CS2、CS5和CS6理想的溶解度，可降低给药剂量从而降低药品的副作用并提高药品的安全性，且在口服后不需要高剂量即可达到所需的治疗血药浓度，有利于药物在人体内的吸收，达到理想的药物生物利用度和药效，符合药用要求。
实施例14：晶型CS1、CS2、CS5和CS6的研磨稳定性研究
取本发明晶型CS1、CS2、CS5和CS6各约20毫克，分别用研钵手动研磨5分钟，研磨前后对样品进行XRPD测试。晶型CS1的测试结果见图32(上图为研磨前，下图为研磨后)，晶型CS2的测试结果见图33(上图为研磨前，下图为研磨后)，晶型CS5的测试结果见图34(上图为研磨前，下图为研磨后)，晶型CS6的测试结果见图35(上图为研磨前，下图为研磨后)。从图中可以看出，本发明晶型CS1、CS2、CS5和CS6经过研磨后晶型不变且结晶度保持良好。
更好的机械稳定性表现在一定机械应力的作用下，仍可保持稳定的物理化学性质。具有较好的机械稳定性的晶型药物对结晶设备要求低，无需特别的后处理条件，在制剂过程中更加稳定，可显著降低药物的开发成本，提升药物质量，具有很强的经济价值。
上述结果表明，本发明的晶型CS1、CS2、CS5和CS6在后续的工艺过程中具备更好的机械稳定性，为后续制剂工艺提供更多选择。例如，可以通过后续干法研磨手段对晶型CS1、CS2、CS5和CS6进行研磨从而得到粒径更小的颗粒。
实施例15：本发明晶型CS1、CS2、CS5和CS6与现有油状物的形态对比
本发明晶型CS1与油状物的形态对比图如图36所示，本发明晶型CS1、CS2、CS5和CS6均呈浅黄色粉末状，取样及定量方便，而根据现有技术方法得到浅黄色油状物，呈粘稠的蜂蜜状(如图36右图)。油状物的取样和定量通常比较困难，且油状物纯度低，稳定性较差，不利于药物存储。此外，油状物作为原料药做成固体制剂往往需要特殊复杂的处理工序，增加制备成本，不利于制剂的制备。
上述实施例只为说明本发明的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本发明的内容并据以实施，并不能以此限制本发明的保护范围。凡根据本发明精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围之内。
