Abstract
Description
Technical Field
[0001] This invention provides an inhibitor for inhibiting programmed cell death, specifically relating to its preparation method and methods and uses for treating and preventing inflammatory and degenerative diseases. Background Technology
[0002] Programmed cell death (PCD) is a highly inflammatory form of cell death that can be induced by various promoting factors, such as necrosis factor (TNF) and FAS ligand. This process can occur in a variety of cell types and is considered a major mode of cell death under pathological conditions, directly associated with a range of inflammatory and degenerative diseases. These diseases include neurodegenerative diseases, stroke, coronary artery disease, myocardial infarction, retinal degeneration, inflammatory bowel disease, kidney disease, liver disease, and many other related conditions.
[0003] RIPK1 (receptor-interacting protein kinase 1) participates in many key intracellular inflammatory signaling pathways, including necroptosis. Scientific experiments have confirmed that this protein can induce a wide range of inflammatory cellular processes by causing cell rupture. RIPK1 is a major regulator of NF-κB signaling and death response, which are key cellular determinants in response to a wide range of inflammatory and death-promoting stimuli in human diseases.
[0004] Therefore, RIPK1 inhibitors can provide more effective inhibition of programmed cell death, and can be used to prevent and treat related inflammatory and degenerative diseases. Summary of the Invention

Subsequently, the Boc protecting group is removed under acidic conditions to obtain a free amine (Formula Ib-3). Then, using an amide condensation reagent, the generated free amine (Formula Ib-3) is condensed with the corresponding acid (Formula III) to obtain the target product (Formula I).
[0110] Option 3:
[0111]
[0112] Boc-L-serine is reacted with a suitable substituted 1-fluoro-2-nitrobenzene using a base to give I-1.

Then, I-14 is converted to α-iodophenyllactam (Formula I-15) via a trimethyliodosilane-mediated iodination reaction, followed by conversion to α-aminophenyllactam with sodium azide, and then Staudinge reduction with triphenylphosphine to generate α-aminophenyllactam (Formula I-16). This is then condensed with an amide condensing agent and a suitable acid (b) to give product I-17. Methylation under basic conditions yields the final product I.
[0119] Option Six:
[0120]
[0121] Compound I-4 is deprotected under acidic conditions (e.g., but not limited to TFA, HCl) to yield the free amine I-5. Different alkynyl compounds (formula a) are reacted with I-4 or I-5 under Sonogashira coupling conditions to yield I-18 or I-19. These are then condensed with a suitable acid (b) using an amide condensing agent (e.g., but not limited to HOAT, EDCI, HATU) to give the final product I.
[0122] Option Seven:
[0123]
[0124] Boc-L-cysteine is reacted with a suitably substituted 1-fluoro-2-nitrobenzene using a base to give I-20. The nitro group is then reduced to an amine I-21 (reduction conditions include, but are not limited to, Zn / AcOH, Fe / NH4Cl / EtOH, Zn / NH4Cl / EtOH), followed by intramolecular condensation using a condensation reagent to give an intermediate of formula I-22 (condensation reagents include, but are not limited to, HOAT, HOBT, HATU, EDCI, BOP, TCFH / NMI). The compound of formula I-22 is methylated to give I-23, followed by deprotection of the Boc group under acidic conditions (e.g., but not limited to TFA, HCl) to give trifluoroacetate I-24. I-23 or I-24 is then reacted with compounds containing different R groups. 6 The alkynyl compound (a) was reacted under Sonogashira coupling conditions to give I-25 or I-26, respectively. Then, it was condensed with an acid (b) using an amide condensing agent (such as, but not limited to, HOAT, EDCI, HATU, TCFH) to give the final product I.
[0125] Option 8:
[0126]
[0127] Under alkaline conditions, Boc-L-cysteine reacts with a suitably substituted thiophene derivative I-27 to give I-28. Nitro reduction of compound I-28 yields I-29, which is then subjected to intramolecular condensation to give compound I-30. I-30 is alkylated to give I-31, which is then reacted with NIS to give iodide I-31. Under acidic conditions, deprotection of the Boc group yields I-35. Then, following Scheme 7, a Sonogashira coupling reaction and an amide condensation reaction are performed (condensation reagents include, but are not limited to, HOAT, EDCI, HATU, and TCFH) to give the final product I.

Then, an anhydrous N-Boc-L-serine solution dissolved in DMF was slowly added dropwise to the system. After reacting for 2 hours, 18.22 g of 2-fluoro-4-bromonitrobenzene was slowly added to the solution. The reaction was continued at 0℃ for 1 hour, then at room temperature for 3 hours. EA (80 ml) was added to the reaction solution, and the solution was slowly poured into a 0.5 M ice-cold hydrochloric acid conical flask. The system was tested with pH paper until it reached a weakly acidic state. Extraction was performed with ethyl acetate, followed by washing with water and saturated brine. The solution was dried over anhydrous sodium sulfate, concentrated, and separated by rapid column chromatography (25%-55% EA in PE) to obtain the yellow intermediate M-1.
