背景技术Background technique
肿瘤生物治疗是应用现代生物技术及其相关产品进行肿瘤防治的新疗法,因其安全、有效、不良反应低等特点,成为继手术、放疗、化疗之后肿瘤治疗的第四种模式,其通过调动宿主的天然防御机制(比如抑制IDO介导的肿瘤免疫逃逸机制)或给予天然产生的靶向性很强的物质来获得抗肿瘤的效应。Tumor biotherapy is a new treatment for cancer prevention and treatment using modern biotechnology and related products. Because of its safety, effectiveness, and low adverse reactions, it has become the fourth mode of tumor treatment after surgery, radiotherapy and chemotherapy. The host's natural defense mechanisms (such as inhibition of IDO-mediated tumor immune escape mechanisms) or the naturally occurring highly targeted substances to achieve anti-tumor effects.
吲哚胺-吡咯-2,3-双加氧酶(Indoleamine-pyrrole-2,3-dioxygenase,IDO)是一种含铁血红素单体蛋白,由403个氨基酸残基组成,包括两个折叠的α-螺旋结构域,大结构域包含催化口袋,底物可在催化口袋内与IDO发生疏水等作用。IDO是催化色氨酸转化为甲酰犬尿氨酸的酶,广泛分布在人和其他哺乳动物(兔、鼠)除肝脏以外的组织中,是肝脏以外唯一可催化色氨酸分解代谢的限速酶,而色氨酸是细胞维持活化和增殖所必需的氨基酸,也是构成蛋白质不可缺少的重要成分。IDO与干扰素(interferon,IFN)、白细胞介素(interleukin,IL)、肿瘤坏死因子等多种细胞因子关系密切,它们在一定条件下可激活IDO。而T-细胞的细胞周期中存在一个对色氨酸水平非常敏感的调节点,一方面,IDO使局部色氨酸耗竭,致使T-细胞停滞于G1期中期,从而抑制了T细胞的增殖;另一方面,IDO催化色氨酸代谢产生的主要产物犬尿素由氧自由基介导引起细胞内氧化剂和抗氧化剂改变而诱导T-细胞凋亡,这是存在于机体的固有的免疫抑制机制。目前大量研究表明IDO在白血病细胞中较高表达,使局部T细胞增殖受抑,抑制T-细胞介导的免疫反应,使T-细胞活化信号转导受阻,从而介导肿瘤细胞逃逸免疫系统的攻击。已经发现大多数人类肿瘤组成性地表达IDO。因此,IDO是一个具潜力的癌症免疫治疗的靶标。Indoleamine-pyrrole-2,3-dioxygenase (IDO) is a heme-containing monomeric protein consisting of 403 amino acid residues, including two folds. The alpha-helical domain, the large domain contains a catalytic pocket, and the substrate can be hydrophobic with the IDO in the catalytic pocket. IDO is an enzyme that catalyzes the conversion of tryptophan to formyl kynurenine. It is widely distributed in tissues other than the liver of humans and other mammals (rabbits, mice) and is the only restriction outside the liver that catalyzes the catabolism of tryptophan. Fast enzyme, which is an essential amino acid for cells to maintain activation and proliferation, is also an indispensable component of protein. IDO is closely related to interferon (IFN), interleukin (IL), tumor necrosis factor and other cytokines, and they can activate IDO under certain conditions. In the cell cycle of T-cells, there is a regulation point that is very sensitive to tryptophan levels. On the one hand, IDO depletes local tryptophan, causing T-cells to arrest in the middle of G1 phase, thereby inhibiting the proliferation of T cells; On the other hand, IDO catalyzes the main product produced by the metabolism of tryptophan. Canine urea is induced by oxygen free radicals to induce changes in intracellular oxidants and antioxidants to induce T-cell apoptosis, which is an intrinsic immunosuppressive mechanism present in the body. A large number of studies have shown that IDO is highly expressed in leukemia cells, which inhibits the proliferation of local T cells, inhibits T-cell-mediated immune responses, and blocks T-cell activation signal transduction, thereby mediating tumor cell escape from the immune system. attack. Most human tumors have been found to constitutively express IDO. Therefore, IDO is a potential target for cancer immunotherapy.

In general, amorphous drug products have no regular crystal structure and often have other defects, such as poor product stability, difficulty in filtration, agglomeration, and poor fluidity. These differences often lead to difficulties in production amplification. The stability of the existing crystal form needs to be improved. Therefore, it is necessary to improve the various properties of the compound. We need to study in depth to find new crystal forms with high purity and good chemical stability.
