代表性研究成果
案例一：瑞戈菲尼（REG）是一种口服多激酶抑制剂，用于治疗胃肠道间质瘤、转移性结直肠癌和晚期肝细胞癌。REG水溶性低，目前以其一水合物形式（REG·H2O）上市，化合物专利于2024年到期，晶型专利于2027年到期。为提高REG水溶性，丰富REG固体形式，突破其晶型专利壁垒，本研究合成了REG与丙二酸（REG–MA）、戊二酸（REG–GA）和庚二酸（REG–PA）的三种共晶，对其进行了全面的固态表征。与商用晶型相比，REG–GA和REG–PA具有显著提高的表观溶解度和溶解速率，同时不影响药物的吸湿性和物理化学稳定性。此外，共晶的形成也改善了REG的可压片性。表明REG–GA和REG–PA具有较大的潜力用于REG改良型制剂的开发。（CrystEngComm 2021, 23, 653–662. DOI: 10.1039/d0ce01341b）
案例二：维罗非尼（VEM）是一种选择性的BRAF V600激酶抑制剂，临床上用于治疗具有BRAF V600突变阳性的发生转移或不可切除的黑色素瘤。VEM难溶于水，目前以无定形固体分散体形式上市，其化合物专利于2024年到期，晶型专利于2030年到期。为开发水溶性更高、稳定性更好的固体形式，本研究制备了VEM与D-樟脑磺酸（D-CSA），L-樟脑磺酸(L-CSA）及DL-樟脑磺酸(DL-CSA）的三个盐。结果表明，三种盐型的吸湿性、稳定性、可压片性均优于无定形VEM；且大鼠体内的口服吸收远远优于无定形VEM，盐型中维罗非尼的Cmax和AUC值分别比无定形提高了9倍和4倍左右。这可能是由于无定形的VEM在体内结晶，而樟脑磺酸盐在体内保持稳定的晶相所致。这一工作为开发具有更好的体内外性质的VEM改良型制剂提供了研究基础。（Journal of Drug Delivery Science and Technology 2022, 70, 103230. DOI: 10.1016/j.jddst.2022.103230）
案例三：利巴韦林（RBV）是一种广谱抗病毒药物，溶解度高（140 mg/mL），剂量大（800-1200 mg/日），血药浓度峰谷效应和不良反应较严重。为了降低药物的溶解度和溶解速率，减缓药物释放，从而降低峰谷效应和不良反应，本研究制备了利巴韦林与溶解度相对较低的3,5-二羟基苯甲酸、没食子酸、巴比妥酸形成的三个共晶。体外释放曲线显示，形成共晶有效降低了药物的释放速率，特别是3,5-二羟基苯甲酸形成了氢键框架结构来包结药物，其释放速率降低最为明显。研究表明，与溶解度相对较低的共晶配体形成共晶是延缓药物释放的有效策略。（Cryst. Growth Des. 2014, 12, 6399–6408. DOI: 10.1021/cg501247x）
案例四：阿昔洛韦是一种嘌呤核苷类似物，用于治疗单纯疱疹病毒感染，药用晶型为其2/3水合物（ACV·2/3H2O）。阿昔洛韦是一种BCS IV类药，溶解度低（约1.6 mg/mL），渗透性差（log P = 1.56），导致经皮吸收受限。本研究制备了阿昔洛韦与马来酸的盐，以及与富马酸和戊二酸的两种共晶。体外溶出和经大鼠皮肤的渗透性评价显示，与药用晶型相比，盐和共晶的最大表观溶解度均有显著提高；阿昔洛韦与富马酸和戊二酸共晶的累计渗透量和渗透速率有明显改善，而马来酸盐的渗透性有所降低。表明形成共晶可同时改善药物的水溶性和经皮渗透性。（CrystEngComm 2013, 15, 6457–6460. DOI: 10.1039/c3ce41017j）
案例五：阿德福韦酯（AD）是一种核苷酸类似物，用于治疗慢性乙肝。AD易降解，化学稳定性差，其降解路径包括磷酸酯水解和腺嘌呤基团聚合。为提高其稳定性，本研究制备了AD与没食子酸的共晶，以及与水杨酸和马来酸的盐。动态水分吸附实验显示，AD在70% RH下逐渐吸水转晶形成其二水合物，而共晶和盐在高湿度下保持稳定。在加速稳定性实验条件下，AD原料药逐渐降解，6个月后药物含量仅为93%；形成共晶或盐后，其降解过程得到明显抑制，6个月后的药物含量仍超过98%。为进一步考察共结晶分别对水解和聚合过程的影响，将样品置于60 °C/75% RH条件下，发现3天后AD原料药有27%发生水解，有51%发生聚合，而共晶和盐的水解和聚合过程均受到显著抑制，表现出显著改善的稳定性。结合晶体结构分析，提出AD稳定性提高的相关机制：AD与配体共结晶形成了稳定的异元氢键超分子合成子，同时相邻的药物分子被共晶配体隔开，能够同时抑制AD的水解和聚合反应。（Eur. J. Pharm. Sci. 2016, 85, 141–148. DOI: 10.1016/j.ejps.2015.10.006）
案例六：替莫唑胺（TMZ）是治疗恶性胶质细胞瘤的一线药物，具有体内消除快，口服半衰期短，稳定性差和压片性能差等问题。黄芩素（BAI）具有显著的抗胶质瘤活性及良好的血脑屏障通透性，但水溶性差（16.0 μg/mL），口服生物利用度低。为克服传统复方药物均一性差、稳定性差、制剂相容性差的问题，并同时优化两种药物理化性质，本研究制备了替莫唑胺与黄芩素的药物-药物共晶。研究表明，形成共晶后，替莫唑胺的物理化学稳定性和压片性均得到显著改善；黄芩素的最大溶解度提高到原料药的25倍以上，而替莫唑胺的溶解度降低至原料药的1/10左右，极大地减小了二者的溶解度差异，改善了制剂相容性。大鼠口服药动学实验显示，形成共晶后，黄芩素的最大血药浓度及口服生物利用度显著增加；替莫唑胺的口服半衰期延长至原料药的2.6倍，说明其在病灶处的作用时间可能会相应地延长。因此，替莫唑胺-黄芩素共晶有望开发为一种克服传统复方药物的固有缺陷，且理化性质和药动学性质明显优于各原料药的改良型复方制剂。（Cryst.
