epidermal growth factor receptor tyrosine kinase, inhibitor, antineoplastic, TAS3351, TAS 3351, CU9YW8A5TP

Emupertinib is a potent, small-molecule epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor. It possesses selective antineoplastic potential for targeting specific mutant profiles of cancer cells. The compound was originally developed by Taiho Pharmaceutical Co., Ltd. under the developmental code TAS3351

Development Profile

The International Nonproprietary Name (INN) for this therapeutic chemical structure was formally proposed under the World Health Organisation (WHO) proposed INN list 132 in early 2025. Global research pipelines list the compound’s structural classification profile within non-small cell lung cancer (NSCLC) primary discovery programs. The drug currently remains a specialized compound designated for global laboratory research use only, rather than standard human prescription or veterinary clinical treatments

 -5-methylpyrazine-2-carboxamide The title compound was obtained by following the same method as in Example 29 (step 6), except that 5-methylpyrazine-2-carboxylic acid was used instead of 5-(fluoromethyl)-2-methylpyrazole-3-carboxylic acid used in Example 29.

(Step 4)
Synthesis of N-(4-(4-amino-6-ethynyl-5-(quinoline-3-yl)-7H-pyrrolo[2,3-d]pyrimidine-7-yl)bicyclo[2.2.1]heptan-1-yl)-5-methylpyrazine-2-carboxamide (compound (1))
[Chemical Formula 7]

It can be obtained by deprotecting the acetylene protecting group TES of N-(4-(4-amino-5-(quinoline-3-yl)-6-((triethylsilyl)ethynyl)-7H-pyrrolo[2,3-d]pyrimidine-7-yl)bicyclo[2.2.1]heptan-1-yl)-5-methylpyrazine-2-carboxamide obtained in Step 3 under basic conditions.
 The reagents used to create basic conditions are not particularly limited as long as the reaction proceeds, but examples of inorganic bases include metal hydroxides (sodium hydroxide, calcium hydroxide, etc.), metal hydrides (lithium hydride, sodium hydride, etc.), and metal carbonates (sodium carbonate, potassium carbonate, cesium carbonate, calcium carbonate, lithium carbonate, magnesium carbonate, sodium bicarbonate, etc.). Examples of organic bases include metal alkoxides (sodium methoxide, potassium tert-butoxide, etc.), metal amides (sodium amide, lithium diisopropylamide, etc.), alkyl metal compounds (n-butyllithium, trimethylaluminum, etc.), alkylamines (triethylamine, tetramethylethylenediamine, piperidine, 1,4-diazabicyclo[2.2.2]octane, etc.), heterocyclic amines (diazabicycloundecene, pyridine, imidazole, etc.), and quaternary ammonium fluorides (tetra-n-butylammonium fluoride). Preferably, the reagent used to create basic conditions is a reagent that does not contain fluoride ions, more preferably a metal carbonate, and even more preferably potassium carbonate. These can be used alone or in combination to adjust the pH to the desired level.
 The amount of reagent used is not particularly limited as long as the reaction proceeds, but for example, 0.1 to 50 moles can be used per mole of the starting compound (the compound represented by formula (II)). Preferably, 0.1 to 10 moles, and more preferably 0.1 to 2 moles.

Sonrotoclax

CAS 2383086-06-2

MW 890.1 g/mol, MFC49H59N7O7S

FDA APPROVED 5/13/2026, Beqalzi, APPROVALS 2026, BGB-11417, BGB 11417, 30R67U9KYS

N-[4-[(4-hydroxy-4-methylcyclohexyl)methylamino]-3-nitrophenyl]sulfonyl-4-[2-[(2S)-2-(2-propan-2-ylphenyl)pyrrolidin-1-yl]-7-azaspiro[3.5]nonan-7-yl]-2-(1H-pyrrolo[2,3-b]pyridin-5-yloxy)benzamide

To treat adults with relapsed or refractory mantle cell lymphoma after at least two lines of systemic therapy, including a Bruton’s tyrosine kinase inhibitor

Sonrotoclax is a potent, orally active Bcl2 inhibitor. Sonrotoclax has effective cell killing effect against a variety of lymphoma and leukemia cell lines.

Regulatory Status & Primary Indication

On May 13, 2026, the U.S. Food and Drug Administration (FDA) granted accelerated approval to sonrotoclax for treating adult patients with relapsed or refractory mantle cell lymphoma (MCL). [1]

  • Eligibility Requirement: Patients must have undergone at least two prior lines of systemic therapy, which must include a Bruton’s tyrosine kinase (BTK) inhibitor.
  • Clinical Performance: In the supporting Phase 1/2 BGB-11417-201 trial, sonrotoclax demonstrated an overall response rate (ORR) of 52% and a median time to response of 1.9 months

Sonrotoclax is an orally bioavailable inhibitor of the anti-apoptotic protein B-cell lymphoma 2 (Bcl-2), with potential pro-apoptotic and antineoplastic activities. Upon oral administration, sonrotoclax specifically binds to and inhibits the activity of the pro-survival protein Bcl-2. This restores apoptotic processes and inhibits cell proliferation in Bcl-2-overexpressing tumor cells. Bcl-2, a protein that belongs to the Bcl-2 family, is overexpressed in various tumor cell types and plays an important role in the negative regulation of apoptosis. Its tumor expression is associated with increased drug resistance and cancer cell survival.

Sonrotoclax is an investigational new drug that is being evaluated for the treatment of hematologic malignancies, particularly chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL).[1] It is a potent and selective BCL2 inhibitor that can overcome resistance associated with BCL2 mutations, such as the G101V variant, which limits the effectiveness of first-generation inhibitors like venetoclax.[2]

xample 16. Preparation of 2-(3. 5-dichloro-4-(4-hvdroxy-3-isopropylbenzyl) phenoxy)-N-methylacetamide (MA-JD21; 10b)

0142] 2-(3, 5-dichloro-4-(4-hydroxy-3-isopropylbenzyl) phenoxy) acetic acid (100 mg, 0.27 mmol, 1 equiv.) was dissolved in methanol (5 mL) in a sealed tube. Sulfuric acid (1 drop) added to it and the reaction was sealed and heated to 65°C for one hour while stirring. It was cooled to room temperature and TLC analysis (ethyl acetate: hexane 1 : 1) shows complete conversion to the intermediate methyl ester. To this was then added 40% methyl amine in water (320μ1, 4mmol, 15 equiv.). The reaction is resealed and heated to 65°C for one hour. The reaction flask was cooled to room temperature and sodium hydroxide (0.5N, 10 mL) added to it. The reaction product was extracted with dichoromethane (3 x 50 mL). The organic layers were combined, dried on anhydrous Mg2S04, filtered and concentrated. Purification by flash chromatography (50% hexane in ethylacetate) gave the product as a white solid (65 mg, 0.17 mmol, 63%). XH NMR (400 MHz, MeOH-c¾): 5=7.12 (s, 2H), 7.01 (d, IH, J=1.98Hz), 6.77 (dd, IH, J=8.21Hz, 2.26Hz), 6.62 (d, IH, J=8.21Hz), 4.56 (s, 2H), 4.15 (s, 2H), 3.23 (septet, IH, J=7.14Hz), 2.85 (s, 3H), 1.17 (d, 6H, J= 6.93Hz).

Elisrasib (D3S-001) is a next-generation, orally available KRAS G12C inhibitor developed by D3 Bio that demonstrates high potency, sustained target engagement, and strong clinical activity in advanced solid tumors, including those resistant to first-generation inhibitors. As of April 2026, clinical trials show it has a 52% objective response rate (ORR) in G12C inhibitor-naive patients and a 30% ORR in refractory populations.

Key Aspects of Elisrasib (D3S-001):

  • Mechanism of Action: It is a highly potent, covalent inhibitor that selectively binds the GDP-bound (inactive) form of the KRAS G12C mutant, effectively halting tumor cell proliferation and metastasis.
  • Superior Efficacy: Preliminary data suggests elisrasib may be more potent than earlier inhibitors like sotorasib and adagrasib, providing higher target occupancy at lower doses.
  • Clinical Performance (AACR 2026 Data):
    • Naive Patients: 52% ORR, with a median duration of response (mDOR) of 16.5 months and median progression-free survival (mPFS) of 12.2 months at the 600 mg dose.
    • Refractory Patients: 32% ORR, with a mDOR of 15.6 months and mPFS of 8.1 months.
  • Targeted Cancers: Clinical trials are focused on KRAS G12C-mutant tumors, specifically non-small cell lung cancer (NSCLC), colorectal cancer (CRC), and other solid tumors.
  • Safety Profile: The drug has shown good tolerability and a safe profile in early studies.

Elisrasib is in Phase 1/2 development and was highlighted for its promising results in treating patients with KRAS G12C-mutant tumors

Elisrasib is an orally bioavailable inhibitor of the oncogenic KRAS substitution mutation G12C, with potential antineoplastic activity. Upon oral administration, elisrasib selectively targets the KRAS G12C mutant and inhibits KRAS G12C-mediated signaling. This may halt proliferation and metastasis in susceptible tumor cells. KRAS, a member of the RAS family of oncogenes, serves an important role in cell signaling, division and differentiation. Mutations of KRAS may induce constitutive signal transduction leading to tumor cell proliferation, invasion, and metastasis.

Example 17

Step 6: Synthesis of Compound 17

      Dichloromethane (5 mL) was added to a dry reaction flask, and then compound 17-6 (50 mg, 82.29 μmol, 1 eq), 2-fluoroacrylic acid (14.82 mg, 164.58 μmol, 2 eq), and N,N-diisopropylethylamine (31.90 mg, 246.87 μmol, 43.00 μL, 3 eq) were added. The mixture was stirred. The reaction system was cooled down to −60° C. and O-(7-azabenzotriazol-1-yl)-N,N,N,N-tetramethyluronium hexafluorophosphate (37.55 mg, 98.75 μmol, 1.2 eq) was added. The mixture was then stirred for 0.5 h. The mixtures were combined for treatment. The reaction mixture was quenched by adding water (5 mL) to the reaction solution and the layers were separated. The organic phase was dried with anhydrous sodium sulfate and filtered. The filtrate was concentrated under reduced pressure to give a crude product, which was purified by a high-performance liquid chromatography column {column: Welch Xtimate C18 100*25 mm*3 μm; mobile phase: [H 2O(0.05% HCl)-ACN]; acetonitrile %: 20%-50%, 8 min} to give compound 17.

To a 50 L glass reactor was charged Compound 15 (1.91 kg, 1.0 eq) and DMF (13.9 kg). The mixture was agitated at 20-30° C. until all of the solids were dissolved. Compound 2 (1.70 kg, 1.2 eq) and DMF (3.8 kg) were charged. The mixture was agitated at 20-30° C. until all of the solids were dissolved. DIPEA (2.20 kg, 5.50 eq) was charged at 20-30° C. and the mixture was cooled to −20-−10° C. under agitation. Ethyl cyanoglyoxylate-2-oxime (Oxyma) (0.48 kg, 1.1 eq) was charged to the reactor and the reaction mixture was agitated at −20 to −10° C. for 30 min. PyBOP was charged as a DMF solution (1.89 kg dissolved in 3.62 kg DMF, 1.2 eq) to the reactor at −20 to −10° C. in </=1 h. The reaction mixture was agitated at −20 to −10° C. for 1-3 h. Reaction monitoring by HPLC showed the reaction was complete.
      The crude reaction mixture was diluted with EtOAc (3.6 kg) and partitioned with a mixture of EtOAc (65 kg) and brine (25 wt %, 132 kg). The biphasic mixture was agitated at 20-30° C. for 1 h and filtered through a pad of diatomite. EtOAc (11 kg) was used to rinse the reactor and spent filter aid wet cake. The combined filtrates were allowed to stand for 1 h before the phases were separated. The organic layer was washed once with brine (25 wt %, 90 kg×2). HCl (0.6 M aqueous solution, 71 kg) was charged to the isolated organic layer at 5-20° C. The biphasic mixture was agitated at 10-20° C. for 1 h. The phases were separated, and the upper lean organic phase was extracted with HCl (0.6 M aqueous solution, 30 kg). The combined rich aqueous phases were washed three times with EtOAc (34 kg×3). To the washed aqueous phase was charged EtOAc (34 kg) and the pH was adjusted to pH 9-10 by charging Na 2CO aqueous solution (30 wt %) at 10-20° C. The mixture was agitated at 10-20° C. for 1 h and the phases were separated. The lean aqueous phase was extracted with EtOAc (34 kg), and the combined rich organic phases were washed twice with brine (25 wt %, 90 kg×2). The resulting organic layer was then washed with a solution of acetic acid in brine (prepared by dissolving 0.23 kg glacial acetic acid and 8 kg 25 wt % brine in 115 kg water) (39 kg×2), a solution of Na 2CO in brine (prepared by dissolving 1.3 kg Na 2CO and 8 kg 25 wt % brine in 31 kg water) (40 kg), and brine (25 wt %, 92 kg), respectively. The crude organic solution was then treated with CUNO® by filtering through a cartridge and the filtrate was concentrated under reduced pressure at NMT 40° C. to ˜30 L. The crude residue was then crystallized by charging n-heptane (57 kg) with seed (0.040 kg).
      The crude product was then further purified by recrystallization with a mixture of EtOAc and n-Heptane to give purified Compound A as a white solid.

Elecoglipron (AZD5004 / ECC-5004) is a glucagon-like peptide 1 (GLP-1) receptor agonist. In vitro, AZD5004/ECC5004 binds the human GLP-1 receptor with high affinity (IC₅₀ ~ 2.4 nM), drives G s-coupled cAMP signaling with low-nanomolar potency (EC₅₀ ~ 2–6 nM in HEK293/β-cell cAMP and GSIS assays), shows partial agonism in some cell systems without detectable β-arrestin recruitment or receptor internalization, and potentiates glucose-stimulated insulin secretion (EC₅₀ ~ 5.9 nM). In in vivo non-human primate studies, oral dosing produced robust pharmacodynamic effects — insulin secretion and glucose clearance with estimated EC₅₀ ~ 0.022 nM — and dose-dependent reductions in body-weight gain over long-term dosing, consistent with GLP-1-mediated metabolic effects

O-GlcNAcase enzyme inhibitor, ASN90, ASN 90, E9QIS63WUM, ASN 120290

Egalognastat (ASN90) is a potent, selective, and brain-penetrant O-GlcNAcase (OGA) inhibitor (\(IC_{50} = 10.2 \text{ nM}\)). It acts as a disease-modifying agent in pre-clinical studies for neurodegenerative conditions by enhancing protein O-GlcNAcylation, which regulates tau and \(\alpha \)-synuclein pathology. Egalognastat is under investigation for diseases like Alzheimer’s and Parkinson’s.

Key Details on Egalognastat (ASN90):

  • Mechanism: As a substrate-competitive OGA inhibitor, it binds to the OGA enzyme and reduces the removal of O-GlcNAc from proteins.
  • Disease Targets: It is primarily studied for tauopathies and \(\alpha \)-synucleinopathies.
  • Efficacy: Preclinical data shows it raises O-GlcNAcylation of brain proteins and has shown therapeutic potential in models of neurodegeneration.
  • Distinction: Unlike earlier sugar-based inhibitors (like Thiamet G), Egalognastat is chemically distinct.
  • Status: It is primarily used for research and preclinical development.
  • Related Research: Recent studies (2025) have analyzed the potential synaptotoxic effects of OGA inhibitors, including Egalognastat (ASN90) and Ceperognastat, indicating that while they are effective for removing misfolded proteins, they may interfere with synaptic plasticity.

75 mg (0.114 mmol) of tert-butyl 4-(8-((5-chloro-4-((2-(N,N-dimethylaminosulfonyl)phenyl)amino)pyrimidin-2-yl)amino)-6-methyl-2,3-dihydrobenzo[b][1,4]dioxin-5-yl)piperidine-1-carboxylic acid ester was dissolved in dichloromethane (10 mL), and trifluoroacetic acid (1 mL) was added. The mixture was stirred at room temperature for 12 hours. The starting material disappeared as detected by TLC. Water (20 mL) was added, and the mixture was separated. The aqueous phase was extracted twice with dichloromethane (20 mL × 2). The organic phases were combined, dried over anhydrous sodium sulfate, and the solvent was removed by rotary evaporation. The crude product was purified by silica gel column chromatography (methanol:dichloromethane = 1:50) to obtain the final product (30 mg, yield 47.2%).
