Description
Technical Field
The invention belongs to the field of drug development, and particularly relates to 1,4(1,4) -diphenyl heterocycle hexa-tomato-12,43-diyl derivatives, processes for their preparation and their use.
Background
Hepatitis c virus HCV belongs to the family flaviviridae, which includes at least three genera: pestiviruses (pestiviruses), which cause disease mainly in cattle and pigs; flaviviruses (flaviviruses), the major cause of dengue and yellow fever; and the hepatitis c virus (hepaciviruses), HCV being the only member of this genus. Flavivirus members, greater than 68, can be divided into different groups based on serological relatedness; clinical symptoms present with diversity, including fever, encephalitis, and hemorrhagic fever. Flaviviruses associated with human diseases of global interest include dengue hemorrhagic fever virus (DHF), yellow fever virus, shock syndrome virus and japanese encephalitis virus. Since the HCV genome is similar in structural and phenotypic characteristics to human flaviviruses and pestiviruses, it is classified as a flaviviridae HCV. Hepatitis c virus is a positive-stranded RNA virus that surrounds a lipid-containing envelope, with spikes, outside the nucleocapsid. HCV has three in vitro cell culture systems of Huh7, Huh7.5 and Huh 7.5.1. The Hepatitis C virus was first discovered in 1974, and in 1989, the gene sequence of the virus was found by the scientists Michael Houghton (Michael Houghton) and colleagues in the United states by using a molecular biology method, and the Hepatitis C virus was cloned and named Hepatitis C (Hepatitis C) and Hepatitis C Virus (HCV).
HCV virions are enveloped positive strand RNA viruses, HCV-RNA consisting of approximately 9500-10000bp, 319-341bp in the 5 'and 3' noncoding regions (NCR) and 27-55bp, respectively, containing several forward and reverse repeats, possibly associated with gene replication, the genomic order being 5 '-C-E1-E2-p 7-NS2-NS3-NS4A/4B-NS5A-NS 5B-3', encoding a polyprotein precursor of approximately 3014 amino acids in length, which can be cleaved by the action of host cells and viral self-proteases into 10 viral proteins, including three structural proteins, namely the nucleocapsid protein (or Core protein, Core) of molecular weight 19KD and two glycoproteins (E1 protein of molecular weight 33KD, E2 protein of molecular weight 72 KD), p7 encoding an integral membrane protein, its function may be an ion channel. The non-structural protein part comprises NS2, NS3, NS4A, NS4B, NS5A and NS 5B; nonstructural proteins are important to the life cycle of the virus. NS2/3 and NS3/4A have protease activity and are involved in the cleavage of viral polyprotein precursors. In addition, the NS3 protein also has helicase activity and is involved in unwinding HCV-RNA molecules to facilitate RNA replication. NS5B has RNA-dependent RNA polymerase activity and is involved in HCV genome replication; NS5B lacks proofreading function, and therefore mutations occur at a high frequency when the HCV viral genome replicates. The exact mechanism of action of NS5A is not well understood, but NS5A interacts with a variety of host cell proteins, and is an essential protein in viral genome replication and virion packaging, and therefore NS5A is an attractive target for the development of HCV-specific antiviral therapies.
HCV has been found to be divided into six genotypes 1-6, with the different genotypes responding differently to different treatments. HCV has remarkable heterogeneity and high variability, and the analysis and comparison of HCV strains with known whole genome sequences show that the nucleotide and amino acid sequences of the HCV strains have large differences, and the variation degrees of various parts of the HCV genome are inconsistent, such as the most conservative 5 '-NCR, the homology is 92-100%, and the variation degree of the 3' NCR region is high. The most conserved, non-structural (NS) region of the C region is the second of the HCV-encoding genes, and the most variable region encodes the envelope protein E2/NS 1. Researchers have classified HCV viruses into different genotypes based on sequence similarity of HCV genomes, each genotype may be further classified into different subtypes, and at least 24 subtypes of 6 genotypes have been found so far. HCV has different genotypes distributed around the world, genotype 1, genotype 2 and genotype 3 all occur around the world, genotype 4 and genotype 5 are mainly distributed in the middle east and africa, and genotype 6 is mainly found in southeast asia. The major genotype 1 in the united states accounts for about 70% of HCV patients (of which 1a is about 36% and 1b is about 24%), with the remaining 30% being predominantly genotype 2 and genotype 3. About 66% of HCV patients in China are genotype 1b, and 14% are genotype 2 a. According to epidemiological statistics published in 2014 in the journal of Chinese internal medicine, China has obvious regional differences, and the types 2, 3 and 6 account for a high proportion in the west and south of China.
Hepatitis C Virus (HCV) has severely compromised human health, causing chronic liver diseases such as cirrhosis and hepatocellular carcinoma in a large number of infected individuals, estimated to be 2-15% of the world population. HCV viruses are transmitted mainly through body fluids, and there is no vaccine to prevent HCV infection to date. According to the world health organization, there are over 2 million infected individuals worldwide, with at least 3 to 4 million people infected per year. Once infected, approximately 20% of people clear the virus, but the rest become HCV carriers. HCV patients are a large population, with an estimated 3% of the global population being about 1.7 billion HCV patients. HCV patients in the united states account for 1.4% of the population, approximately 3-4 million people. The epidemiological data of HCV patients lack authority in china, the most conservative estimate is 0.42% of the population, and some reports suggest that HCV patients in china are up to 3.8% of the population, and the number estimates that HCV patients in china should be between 6 million and 3 thousand and 8 million. Of HCV patients, 10% to 20% of chronically infected individuals eventually develop liver-destructive cirrhosis or cancer.
For a long time and even now in many developing countries, either acute or chronic hepatitis c, the standard treatment regimen is peginterferon (α -2a or α -2b) in combination with ribavirin. The treatment scheme of the combination of polyethylene glycol interferon (alpha-2 a or alpha-2 b) and ribavirin has a plurality of problems, including long medication period, great toxic and side effects, low response ratio of patients and the like. Therefore, there is a need to develop more effective and novel therapies to address the unmet medical need caused by HCV infection. The development of Drugs (DAAs) against HCV targets in recent years has made tremendous progress in these areas, and the current trend in HCV therapy worldwide is towards DAA combinations that do not require interferon and ribavirin. The main DAA drugs are NS5B inhibitors, NS5A inhibitors, NS3/4A inhibitors. Advantages (or potential advantages) of the DAA combination compared to interferon in combination with ribavirin include: high persistent virus response rate SVR (basically curable), shortened treatment cycle, avoidance of drug resistance, pursuit of broad spectrum (effective against multiple genotypes of HCV).
The first successful DAA drugs were NS3/4A inhibitors, including Telaprevir (Vertex/Janssen), boceprevir (merck), all approved by the FDA in 2011. NS5B inhibitors include ABT-333 in the Gelidide combination of Sofosvubir and Eberavid. NS5A is the last successfully developed drug for these three DAAs, including DAClatatasvir of BMS, Ledipasvir (in combination with Sofosbuvir) and GS-5816 of Gilidide, ABT-267 of triple drug of Alberd, ACH-3102 of Achillion, MK-8742 of Merck, and so on. NS5A inhibitors may cause a faster and greater reduction in viral load in patients than NS3/4A and NS5B inhibitors. In addition, ACH-3102 and GS-5816 are still active on many of the Daclatasvir and Ledipasvir resistance mutations.
