  • the invention belongs to the technical field of medicine and chemical industry, and relates to a tricyclic diterpene analog and its synthesis and application in antitumor.
  • Hedgehog (Hh) signaling pathway plays a crucial role in embryonic development, tissue regeneration and tumorigenesis. Abnormal activation of the Hh signaling pathway can cause a series of diseases, including basal cell carcinoma, medulloblastoma, rhabdomyosarcoma, breast cancer, lung cancer, gastric cancer, adenocarcinoma, and colon cancer. Smoothened (SMO) protein plays a key role in the Hh signaling pathway, and inhibiting the activity of SMO protein is one of the important means to inhibit the Hh signaling pathway (Nat Rev Mol Cell Biol.2013, 14, 416-29). In recent years, the research and development of drugs targeting SMO has achieved leapfrog development.

Abstract

Disclosed are a tricyclic diterpene analogue represented by formula (I) and a preparation method therefor. By using testosterone as a raw material, and by means of methylation, ethylene glycol protection, oxidation, Baeyer-Villiger oxidation, reduction, hydrolysis and other reactions, and passing through cyanation and a Wittig reaction to extend a carbon chain, a corresponding parent nucleus compound is obtained; and the parent core compound is subjected to amidation to obtain the tricyclic diterpene analogue. Also disclosed is an application of the tricyclic diterpene analog in inhibiting a smoothened (SMO) protein and resisting against tumors. The tricyclic diterpene analog binds to a cysteine rich domain (CRD) at an N-terminal of the SMO protein to inhibit the activity of a hedgehog (Hh) signaling pathway, which thus inhibits the growth of tumor cells and has good tumor-resisting application prospects. In addition, the present application may solve the problem of drug resistance of existing clinical SMO inhibitors, thus providing a new solution for the treatment of related diseases.

Description

一种三环二萜类似物及其合成和应用A kind of tricyclic diterpene analog and its synthesis and application 技术领域technical field
本发明属于医药化工技术领域,涉及一种三环二萜类似物及其合成和在抗肿瘤方面的应用。The invention belongs to the technical field of medicine and chemical industry, and relates to a tricyclic diterpene analog and its synthesis and application in antitumor.
背景技术Background technique
癌症治疗已成为全世界面临的重要问题。世界卫生组织国际癌症研究机构(IARC)发布的2020年全球最新癌症负担表明,中国新发癌症人数及中国癌症死亡人数均居全球第一。除了手术治疗外,药物治疗是最为重要的治疗方式。因此,研究新型抗肿瘤药物一直是医药领域的研究热点。Cancer treatment has become an important issue facing the world. According to the latest global cancer burden in 2020 released by the International Agency for Research on Cancer (IARC) of the World Health Organization, the number of new cancers and the number of cancer deaths in China rank first in the world. In addition to surgery, drug therapy is the most important treatment. Therefore, the study of new anti-tumor drugs has always been a research hotspot in the field of medicine.
Hedgehog(Hh)信号通路在胚胎发育、组织再生以及肿瘤发生中起着至关重要的作用。Hh信号通路异常激活会引起一系列的疾病,包括基底细胞癌、髓母细胞瘤、横纹肌肉瘤、乳腺癌、肺癌、胃癌、腺癌以及结肠癌等。Smoothened(SMO)蛋白在Hh信号通路上起着十分关键的作用,抑制SMO蛋白的活性是抑制Hh信号通路的重要手段之一(Nat Rev Mol Cell Biol.2013,14,416-29)。近年来,针对SMO的药物研发已经取得了跨越式的发展,三种SMO的抑制剂,如诺华公司的索尼德吉(LDE225/Sonidegib,Drugs.2015,5,1559-66)、罗氏制药的维莫德吉(GDC0449/Vismodegib,Drug Discovery.2012,11,437-438)及辉瑞制药的格拉德吉(Glasdegib,Clin Cancer Res.2019,25,6021-6025)均已被美国FDA批准上市,其中索尼德吉和维莫德吉在治疗基底细胞癌(BCC)的病人上有着非常显著的效果,格拉德吉在治疗急性髓性白血病(AML)的病人上可以明显的延长病人的寿命。针对其他癌症,目前一些SMO抑制剂也正处于临床研究中,因此SMO抑制剂在癌症治疗方面具有十分广阔的应用前景(Cell Chem Biol.2017,24,252-280)。但研究表明,大部分SMO抑制剂,包括已上市的索尼德吉、维莫德吉和格拉德吉均作用于SMO的7次跨膜结构域上,属非保守区,该区域极易产生耐药性突变(D473H&E518K等)。近期研究发现,SMO的N端Cysteine Rich Domain(CRD)不仅可以结合胆固醇(Nature.2016,535,17-522;Cell.2016,166,1176-1187),还可以发生胆固醇修饰(Molecular Cell.2017,66,154–162),并且该区域相对比较保守,不易产生突变。抑制SMO的CRD和胆固醇的结合可以很好的抑制Hh信号通路,进而起到抗肿瘤作用。Hedgehog (Hh) signaling pathway plays a crucial role in embryonic development, tissue regeneration and tumorigenesis. Abnormal activation of the Hh signaling pathway can cause a series of diseases, including basal cell carcinoma, medulloblastoma, rhabdomyosarcoma, breast cancer, lung cancer, gastric cancer, adenocarcinoma, and colon cancer. Smoothened (SMO) protein plays a key role in the Hh signaling pathway, and inhibiting the activity of SMO protein is one of the important means to inhibit the Hh signaling pathway (Nat Rev Mol Cell Biol.2013, 14, 416-29). In recent years, the research and development of drugs targeting SMO has achieved leapfrog development. Three kinds of SMO inhibitors, such as Novartis’s Sonidegib (LDE225/Sonidegib, Drugs.2015,5,1559-66), Roche’s Both Moderji (GDC0449/Vismodegib, Drug Discovery.2012, 11, 437-438) and Pfizer’s Glasdegib (Clin Cancer Res. 2019, 25, 6021-6025) have been approved for marketing by the US FDA. Ji and Vimodji have very significant effects in the treatment of patients with basal cell carcinoma (BCC), and Gladji can significantly prolong the life of patients in the treatment of patients with acute myeloid leukemia (AML). For other cancers, some SMO inhibitors are currently in clinical research, so SMO inhibitors have very broad application prospects in cancer treatment (Cell Chem Biol. 2017, 24, 252-280). However, studies have shown that most of the SMO inhibitors, including the marketed Sonideji, Vemodji and Gladji, all act on the 7 transmembrane domains of SMO, which is a non-conserved region, and this region is very prone to resistance. Drug mutations (D473H&E518K, etc.). Recent studies have found that the N-terminal Cysteine Rich Domain (CRD) of SMO can not only bind cholesterol (Nature.2016,535,17-522; Cell.2016,166,1176-1187), but also undergo cholesterol modification (Molecular Cell.2017 ,66,154–162), and this region is relatively conserved and not prone to mutations. Inhibiting the combination of CRD and cholesterol of SMO can well inhibit the Hh signaling pathway, and then play an anti-tumor effect.
