Abstract

The present disclosure relates to compounds of formula I, wherein the variables are as defined in the specification, pharmaceutical compositions containing them, processes for preparing them and their use.

Description

Heteroaromatic carboxamide compounds and uses thereof
Cross reference to related applications
The present application claims priority from International application PCT/CN2021/089684 filed on 25 th 4 th 2021, the contents of which are incorporated herein by reference in their entirety.
Technical Field
The present disclosure provides heteroaromatic carboxamide compounds that inhibit the bruton's tyrosine kinase BTK. The disclosure also provides methods of preparing these compounds, pharmaceutical compositions comprising these compounds, and methods of using these compounds in the treatment of BTK-related diseases or disorders.
Background
Bruton's Tyrosine Kinase (BTK), a non-receptor tyrosine kinase belonging to the Tec family of kinases, is widely expressed in hematopoietic cells other than T cells. BTK plays a key role in signaling through B cell antigen receptor (BCR) and fcγreceptor (fcγr) in B cells and bone marrow cells, respectively, and is involved in all aspects of B cell development including proliferation, maturation, differentiation, apoptosis and cell migration. Abnormal BTK expression and/or activity has been demonstrated in different cancers and autoimmune diseases.
Significant progress has been made in developing BTK inhibitors as therapeutics targeting hematologic malignancies and chronic inflammatory diseases. In fact, the first generation BTK inhibitor ibrutinib (PCI-32765, imbruvica) has been successfully treated for B-cell malignancies and is approved for Chronic Lymphocytic Leukemia (CLL), recurrent or refractory Mantle Cell Lymphoma (MCL) andMacroglobulinemia (WM). However, treatment disruption occurs in up to 30% of ibrutinib patients, which leads to poor clinical results. While second generation BTK inhibitors that provide greater BTK selectivity, such as acartinib (acalabrutinib), zebutinib (zanubrutinib), and tiratinib (tirabrutinib), can limit off-target toxicity, they are irreversible BTK inhibitors. The compound reacts covalently and irreversibly with cysteine-481 in the ATP binding site of BTK, and thus does not overcome the common mechanism of ibrutinib resistance that occurs in 30% of patients after treatment lasting more than 12 months. Notably, reversible BTK inhibitors include vicat brutinib (vecabrutinib), ARQ-531, and LOXO-305, which inhibit BTK activity in the presence of the C481S mutation independent of cysteine-481 interaction with BTK, and clinical evidence began to appear to show that they can overcome resistance to irreversible BTK inhibitors. In addition, there is currently no approved BTK targeted therapy for chronic autoimmune indications. The slow progression in autoimmune/inflammatory diseases may be due at least in part to the stringent safety requirements of these indications, such as RA and SLE requirements. Accordingly, efforts have been made to find reversible BTK inhibitors with better efficacy and lower toxicity.

General synthetic method
General synthetic method for preparing 1H-pyrazolo [4,3-c ] pyridine-7-carboxamide analogs having general structures shown in A-1 and A-2 (scheme 1)
Based on the synthesis of analogous compounds in the literature (WO 2017042100), A-1-1 is synthesized from the commercially available starting material 2,4, 6-trichloropyridine, followed by bromination and subsequent deprotection to give intermediate A-1-2. Treatment of A-1-2 with hydrazine gives the corresponding cyclized compound A-1-3, which, after separation from its regioisomer A-1-4b, is converted into the key intermediate compound A-1-4a. The target compound with the general structure of A-1 is obtained by carrying out selective and continuous bell wood reaction on two chlorine groups on a key intermediate A-1-4a 4, 6-dichloro-1H-pyrazolo [4,3-c ] pyridine-7-formamide and then carrying out a plurality of steps of functional group conversion. Or compound A-1-1 can be converted to intermediate A-2-2 after carboxylation, amide formation and deprotection. After ring closure and protection, A-2-2 is then converted to the key intermediate A-2-4a. After treatment of A-2-4a with the corresponding amine and subsequent Suzuki reaction, a 4-nitrogen analog having the general structure shown in A-2 can be obtained

Wherein Ra is R 1 attached to the ring through C and Rb is R 1;P1 or P 2 attached to the ring through N or O is a protecting group, R 1 and Ar are as defined herein for formula I.
As described in pathway 1, intermediate B-1-1 can be obtained from commercially available 4-bromo-2, 6-difluorobenzonitrile according to the two-step process disclosed in WO2010059658 (but modified). The protected formylation gives compound B-1-2, which is then converted to compound B-1-3a after separation from its regioisomer B-1-3B. B-1-3a and its deprotected form B-1-3c as key intermediates can be used as starting points for target compounds represented by B-1 or B-2, respectively, prepared in a multi-step sequence.
Or in some cases also use path 2. According to the improved process disclosed in US20180127370 and WO2004065367, commercially available methyl 5-bromo-2-hydroxy-4-methylbenzoate is converted to methyl 5-bromo-2-methoxy-4-methyl-3-nitrobenzoate, which is subsequently converted after the reduction step to the compound methyl 3-amino-5-bromo-2-methoxy-4-methylbenzoate. Subsequent ring closure reactions result in key intermediate B-1-6, which is converted to key intermediate B-1-9 after many bond and functional group conversion steps. The key intermediate B-1-9 is used to prepare the target compound represented by B-1.

PK protocols
ICR mice (male, 6-8 weeks old, 26-30g, each route of administration n=9) were purchased from Shanghai family planning institute (SIPPR) (Shanghai, china). Animals were housed in chambers maintained at a temperature of about 20-26 ℃ and a relative humidity of 40% -70% with a light-dark cycle of 12:12h, free access to food and water. All methods related to animals accord with the Chinese experimental animal management principle. Animal research programs are reviewed and approved by the animal care and use committee. ICR mice received test compounds either intravenously (IV; 1 mg/kg) or orally gavaged (PO; 10 mg/kg) after overnight fast. Food was administered 4 hours after administration. The compounds were formulated in DMA, solutol HS-15 and saline (10:10:80, v/v/v) to give nominal concentrations of 0.2mg/mL (i.v. route) and 1mg/mL (p.o. route) for administration. Blood samples (110 μl) were collected through the jugular sinus at the appropriate time points (each time point n=3). The blood samples were placed in test tubes containing K2EDTA and centrifuged at 5,500rpm for 10 minutes under frozen conditions to separate the plasma. Plasma samples were stored at-20 ℃ prior to analysis. Plasma (20. Mu.L) was mixed with 100. Mu.L of ACN-containing internal standard in 96-well plates to precipitate proteins. After vortexing for 10 seconds, the plates were centrifuged at 3,760rpm for 10 minutes at 4℃and 60. Mu.L of supernatant was diluted with 60. Mu. L H2O prior to LC/MS/MS analysis. Pharmacokinetic parameters were determined using non-compartmental WinNonlin (Pharsight, mountain View, CA, USA) analysis.
Efficacy study
The general procedures for animal care and feeding are in accordance with standard procedures, i.e., the life sciences committee, national research committee. The OCI-LY10 tumor cell line was maintained in vitro as a suspension culture in IMDM medium, which was modified to supplement 20% heat-inactivated fetal bovine serum, 37 ℃ in 5% CO 2 air. Tumor cells will be routinely subcultured for no more than 4-5 passages. Cells grown in exponential growth phase were harvested and counted for tumor inoculation. Each mouse was inoculated subcutaneously in the right flank with OCI-LY10 tumor cells (1X 10 7) in 0.1ml IMDM medium and high concentration Matrigel mixture (1:1 ratio) for tumor development. Mice were randomly assigned to groups based on tumor volume and body weight, such that the average starting tumor size and body weight were the same for each treatment group. Treatment was started when the average tumor volume reached about 120-180mm 3. Tumor size measurements were taken twice weekly with calipers and recorded. Tumor volume was estimated using the following formula (mm 3):TV=a×b2/2, where "a" and "b" are the long and short diameters of the tumor, respectively.
TVs were used to calculate tumor growth inhibition and tumor growth delay. For Tumor Growth Inhibition (TGI), the values were calculated using the following formula:
% T/c= (treatment TVfinal-treatment TVINITIAL)/(medium TVfinal-medium TVINITIAL) ×100
% Tgi= [1- (treatment TVfinal-treatment VTINITIAL)/(mediator TVfinal-mediator TVINITIAL) ]x100
"TVfinal" and "TVINITIAL" are average tumor volumes of the last day and the beginning day.
