Description

Field

[0001] The present disclosure relates generally to compounds of formula (I) for cancer prevention and therapy, and their use in anti-cancer therapy, especially against cancer-related proteins including ALK, ROS1, MET, EGFR and FLT3. Background

[0002] Lung cancer is the leading cause of cancer related death in China and the world wide. In China, the incidence of lung cancer is already surpassed other types of cancer, and each year there are about 800,000 people died from lung cancer. The five-year survival rate of lung cancer is also very low, and it is only about 17%. And this rate havn't change too much since 70s in the last century. This is because traditional chemotherapy and radio-therapy killed normal cells together with cancer cells, which causes decreased immunity and dysfunction of patients physiology. Recently precision medicine provides targeted therapy to patients with specific driver genes which greatly reduced the toxic effect of traditional chemotherapy and radio-therapy and greatly improved patients quality of life.

[0003] Treating ALK (Anaplastic Lymphoma Kinase) mutation positive non-small cell lung cancer with specific small molecular tyrosine kinsae inhibitors greatly improved the efficacy of cancer therapy and patient quality of life. According to the pathological classification, lung cancer can be divided into small cell lung cancer and non-small cell lung cancer. The latter accounts for about 80% of the total number of lung cancer patients. In lung cancer, patients with EML4-ALK gene fusion are about 3-7% of the total number of non-small cell lung cancer patients. The incidence ratio has no significant difference between Asian and western caucasion populations. In clinics, such mutations are often observed in young non-smoker patients (Soda et al. 2007; Nishio et al. 2017; Chan et al., 2017). ALK is a typrosine receptor kinase. Gene fusion of this gene is a strong cancer driver gene which was firstly discovered in anaplastic large cell lymphoma patients, and later were found in many other diseases including diffused large B-cell lymphoma and Inflammatory Myofibroblastic Tumor (IMT) (Wellmann et al., 1997). ALK forms fusion genes with different partners and leads to consitutively activated ALK kinase activities to transform normal cells become cancer cells(Soda et al., 2007; Choi et al., 2008; Cha et al., 2016). In lung cancer, the major fusion partner with ALK is Echinoderm microtubule-associated protein-like 4, EML4. ALK also can form fusion proteins with many other different partners, such as KIF5B, to drive cancer formation (Takeuchi et al. 2008). Such ALK fusion positive cancer cells are highly dependent on ALK kinase activities and inhibition of ALK kinase activity leads to the death of such cells. Several ALK kinase inhibitors have been approved to treat ALK mutant positive cancer. In 2011, Crizotinib developed by Pfizer was approved by FDA to treat ALK positive non-small cell lung cancer. In 2016, Crizotinib was approved to treat non-small cell lung cancer patients with ROS1 (c-ros oncogene 1 receptor tyrosine kinase,c-ros) mutation. With this drug, the progression free survival of the patients was increased to about 10 months (Nishio et al, 2017). Regardless of with or without pretreatment, Crizotinib showed greater benefit to patients. It increased median progression free survival from 7.2 months with chemotherapy to 9.6 months, and which was increased to 13.6 months in Asian patients (Nishio et al., 2017). And the objective response rate was increased from 20% to 65% comparing those treated with chemotherapy. Treating ALK fusion positive patients with specific tyrosing kinase inhibitors provides great benefit to patients in clinics and it made a new milestone in lung cancer therapy.

[0004] There are more than 20 different genes were reported serve as partners of ALK. These different forms of ALK fusion proteins are also highly depend on ALK kinase activity and sensitive to ALK kinase inhibitors. In addition, ALK gene fusions not only play important roles in non-small cell lung cancer, they are also found be critical for many other diseases inincluding patients with ALCL, colorectal cancer (Lin et al., 2009; Lipson et al., 2012), IMT(Lawrence et al., 2000) and ovarian cancer (Ren et al., 2012). ALK gene amplification and activating mutants were also reported in glioblastoma (Chen et al., 2008; George et al., 2008; Janoueix-Lerosey et al., 2008; Mosse et al., 2008). Different ALK fusion forms were found for critical for different disease types. For example, the most frequently observed form is EML4-ALK in non-small cell lung cancer and the most frequently found form is NPM-ALK in ALCL. Furthermore, ALK gene amplification and mutation were also reported in glioblastma. Some of these ALK mutations are also sensitive to ALK inhibitors, and potentially benefit from ALK inhibitor development.

[0005] Although there are great benefit for patients of using ALK kinase inhibitors in clinic, drug resistance eventually developed usually about one year after drug treatment initation. Part of the reason is due to ALK gene amplification or acquired resistance mutations in ALK protein, including L1196M, L1198F, L1152R, L1151TIN, C1156Y, F1174C, G1202R , ,D1203N, S1206Y (Bordi et al., 2017; Dagogo-Jack and Shaw, 2016; Drizou et al., 2017). The most frequent mutation is the Point mutation L1196M which was called gatekeeper mutation. Because Crizotinib is hard to reach brain, resistance was also developed after the occurance of brain metasis. Other resistance mechanisms are activation of other driver genes, including EGFR mutation or activation (30-35%), c-KIT amplification (10%) or Kras or other gene mutations (5%) (Bordi et al., 2017).

[0006] Studies on the drug resistance mechanisms promoted the development of the second generation of ALK kinase inhibitor drugs, which include Ceritinib (Novartis, LDK378), Alectinib (Roche, CH542802) and Brigtinib (Ariad, AP26113). These drugs can overcome many acquired resistance mutations in ALK, including gatekeeper mutation L1196M. In addition, these drugs can penetrate into the brain very well and inhibit the growth of brain metasized tumor. Within these drugs, certinib was approved by FDA in 2014 to treat patients progressed on Crizotinib treatment or patients who are not Crizotinib-tolerated. Second line treatment with Ceritinib increased progression free survival for about 4 months comparing to second line chemotherapy (Shaw et al., 2017). Alectinib was approved in 2014 in Japan and 2015 by FDA in US. It is about 10 fold more potent than Crizotinib in inhibiting ALK kinase activities. The advantage of second line using Alectinib over chemotherapy after Crizotinib resistance was recently reported (Asao et al., 2017). It increased the patients' progression free survival up to 35 months. This indicated that of using ALK kinase inhibitor drugs with optimized drug treatment strategies might make the uncontrolled tumor growth to a controllable chronic diseases. Brigatinib (Takeda) was firstly approved by FDA as breakthrough designation on April 28, 2017 for second line treatment ALK-positive patients who developed resistance to Crizotinib. Comparing to the other two other 2 nd< generation drugs, Brigatinib not only effectively inhibited G1269A, C1156Y, I1171S / T, V1180L, it also blocked the resistance mediated by G1202R (Zhang et al., 2016). In addition, Brigatinib can blocked the activities of both ALK and EGFR, the repsonse rate is 55% and disease control rate was about 86%. Currently, it has been granted priority review as a first-line treatment for ALK positive non-small cell lung cancer.

[0007] Although the development of newer generation more specific tyrosine kinase inhibitor drugs showed high reponse rate in ALK mutant positive non-small cell lung cancer, drug resistance still occurrs. The 3 rd< generation ALK kinase inhibitor Lorlatinib (PF-06463922) can overcome many known acquired ALK resistant mutations, but resistance to Lorlatinib eventually occurred in patients. The number of patients with ALK rearrangement mutation is big and it continues rising. Drug resistance to targeted therapy becomes a big obstacle to improve patients survival and does not fit the development need of the society. The need to overcome drug resistance is big and the developing need of new types of drugs to overcome resistance is urgent.

[0008] Proteolysis targeting technology is a new strategy of drug design. Traditional small molecular design only inhibit the kinase activity of ALK protein, whereas the acquired resistant mutations on the protein are the basis of certain resistance mechanism. We utilize the platform of Proteolysis targeting drug (PROTAD) to develop new ALK targeting drugs. The action mechanisms of these drugs is distinct from traditional small kinase inhibitors. These PROTAD drugs not only inhibit the activity of target proteins such as ALK, but also are able to get rid of target proteins through proteolysis. By using the PROTAC technology, we would like to develop new drugs targeting cancer driver genes such as ALK fusion proteins and getting rid of these target proteins ultimately so as to treat cancer and overcome drug resistance.Summary of the Invention

Generally, such constructs are carried or transported from one organ or part of the body to another organ or part of the body. The carrier is compatible with the other ingredients of the formulation, including the compounds useful in the present disclosure, and is not harmful to the patient, and the carrier must be "acceptable." Some examples of materials that can be used as pharmaceutically acceptable carriers include, but are not limited to, sugars such as lactose, glucose, and sucrose; starches such as corn starch and potato starch; cellulose and its derivatives such as sodium carboxymethyl cellulose, ethyl cellulose and cellulose acetate; powdered tragacanth; malt; gelatin; talc; excipients such as cocoa butter and suppository wax; oils such as peanut oil, cottonseed oil, safflower oil, sesame oil, olive oil, corn oil and soybean oil; glycols such as propylene glycol; polyols such as glycerol, sorbitol, mannitol, and polyethylene glycol; esters such as ethyl oleate and ethyl laurate; agar; buffers such as magnesium hydroxide and aluminum hydroxide; surfactant phosphate buffer solution; and other common non-toxic compatible substances used in pharmaceutical preparations.

[0136] A "therapeutically effective amount" of a compound of the disclosure depends on the age, sex, and weight of the patient, the patient's current medical condition, and the cancer progression of the patient being treated.

[0137] The term "room temperature" used herein refers to the ambient temperature, such as a temperature of 20-30 °C.

[0138] The compound developed by the present invention belongs to a specific protein-degrading agent, which is composed of three parts: a target protein anchoring part, a protein degradation system (such as an E3 ligase) recruitment part, and a linker. In the present disclosure, an inhibitor targeting ALK protein is selected as an anchoring part, and an E3 ligase ligand is combined with an ALK protein inhibitor through a linker to develop a degradation agent targeting ALK protein. Through the specific recognition of target proteins by ALK-TKIs, the phosphorylation of ALK protein is inhibited, and at the same time, E3 ligase specifically ubiquitinates ALK protein to achieve degradation and elimination, and finally can remove the target protein from tumor cells. Because ALK mutation-positive lung cancer cells are highly dependent on the presence and activity of ALK protein, completely degrading ALK protein and inhibiting residual ALK activity can not only inhibit tumorigenesis and progression, but also potentially overcome resistance to targeted drugs. In addition, the degrading agent designed and developed by the present invention can also target and inhibit other tyrosine kinase receptors including ROS1, c-MET, insulin receptor, IGFIR and EGFR with lung cancer drivering mutation, etc. The compounds developed by the present invention provide potentially alternative treatments for cancers that are positive for these targets. This research will provide a new treatment strategy for lung cancer patients in the context of precision medicine.Examples
