帕金森病(Parkinson′s disease,PD)又称为震颤性麻痹,是一种常见的神经退行性疾病,具有进行性、多发性和起病隐匿等特点,主要表现为行动迟缓、肌强直、静止性震颤和姿势不稳。PD在50岁以前人群中发病很少,60岁以后发病迅速上升。据估计,中国PD患者超过200万名,其中65岁以上人群发病率约为1.7%,随着中国逐渐步入老龄化,这个数字有上升的趋势。Parkinson's disease (PD), also known as paralysis shaking, is a common neurodegenerative disease characterized by progressiveness, multiple occurrence, and insidious onset. It mainly manifests as slowness of movement, myotonia, and Resting tremor and postural instability. PD rarely occurs in people before the age of 50, and its incidence increases rapidly after the age of 60. It is estimated that there are more than 2 million PD patients in China, and the incidence rate among people over 65 years old is about 1.7%. As China gradually ages, this number has an upward trend.

By selectively inhibiting monoamine oxidase, it can reduce the decomposition of dopamine and increase the extracellular level of dopamine in the high striatum of the brain. The increased dopamine level can alleviate the symptoms of Parkinson's disease. . This drug is used as a monotherapy (without levodopamine) or as an adjuvant therapy (combined with levodopamine) to treat idiopathic Parkinson's disease.

帕金森症是一种进行性、无法治愈的神经系统疾病,需要长期用药,雷沙吉兰需要每日给药。由于帕金森症主要发病对象为老年人,患者具有记忆力差,容易忘事的特点,因此开发长效帕金森症药物将有极大的市场,本发明人前期的专利CN109422668B提供了一种用于治疗帕金森病的长效雷沙吉兰前药,具有较好的长效效果。Parkinson's disease is a progressive, incurable neurological disease that requires long-term medication, and rasagiline requires daily dosing. Since Parkinson's disease mainly affects the elderly, and patients have poor memory and are prone to forgetting things, the development of long-acting Parkinson's disease drugs will have a huge market. The inventor's early patent CN109422668B provides a method for The long-acting rasagiline prodrug for the treatment of Parkinson's disease has a good long-acting effect.

由于药物的不同晶型对于药物在体内的溶出和吸收有一定的关系,为了保证雷沙吉兰前药在体内稳定的血药浓度,需要对长效前药的多晶型进行研究,获得在药学上可用的稳定晶型,以利于药物更好的发挥长效作用。Since different crystal forms of the drug have a certain relationship with the dissolution and absorption of the drug in the body, in order to ensure the stable blood concentration of the rasagiline prodrug in the body, it is necessary to study the polymorphic form of the long-acting prodrug to obtain the A stable crystalline form that is pharmaceutically available to facilitate the long-acting effect of the drug.

发明内容Contents of the invention

本发明在前期研究成果的基础上,进一步的研究了长效雷沙吉兰前药的多种晶型,其目的在于提供成药性更加的式(Ⅰ)所述化合物多种稳定的晶型,具体为晶型Ⅰ、晶型Ⅱ、晶型Ⅲ和晶型IV,其中晶型Ⅰ、晶型Ⅱ和晶型Ⅲ表现出良好的稳定性。On the basis of the previous research results, the present invention further studies multiple crystal forms of long-acting rasagiline prodrugs, with the purpose of providing multiple stable crystal forms of the compound described in formula (I) with better pharmaceutical properties. Specifically, they are crystal form I, crystal form II, crystal form III and crystal form IV, among which crystal form I, crystal form II and crystal form III show good stability.

本发明的另一个目的在于提供式(Ⅰ)所述化合物多种稳定晶型的制备方法。Another object of the present invention is to provide methods for preparing multiple stable crystal forms of the compound described in formula (I).

本发明的再一目的在于提供式(Ⅰ)所述化合物多种稳定晶型的用途。 Another object of the present invention is to provide the use of multiple stable crystal forms of the compound described in formula (I).

式(Ⅰ)所述化合物为MAO-B抑制剂衍生物,属于雷沙吉兰前药,本发明人通过对雷沙吉兰的结构进行修饰,最终得到的具有长效属性的前体药物,式(Ⅰ)所述化合物通过皮下或肌肉后,在体内形成药物贮库,可持续的释放并转化为雷沙吉兰,保证疗效的同时,还具有长效的作用。但是,注射类长效药物存在药物释放速度的不稳定和释放不完全的问题,其中药物释放速度不稳定表现为药物注射后短时间内的突释或释放过慢,导致药物的副作用增加或无法达到有效血药浓度;而释放不完全则表现为后期药物未能完全的在体内释放,从而导致药物的生物利用度降低。而这都与晶型药物的物理稳定性密切相关。
The compound described in formula (I) is an MAO-B inhibitor derivative and belongs to the rasagiline prodrug. By modifying the structure of rasagiline, the inventor finally obtained a prodrug with long-acting properties. After the compound of formula (I) passes through the subcutaneous or muscle, it forms a drug reservoir in the body, is continuously released and converted into rasagiline, which not only ensures the curative effect, but also has a long-lasting effect. However, injectable long-acting drugs have problems with unstable drug release speed and incomplete release. The unstable drug release speed is manifested by sudden release or too slow release within a short time after drug injection, resulting in increased side effects or inability to Reach the effective blood drug concentration; incomplete release means that the drug is not completely released in the body at a later stage, resulting in reduced bioavailability of the drug.
