Iberdomide


Iberdomide

CAS 1323403-33-3

as HCl: 1560678-63-8

MW 449.5 g/mol, C25H27N3O5

(S)-3-(4-((4-(Morpholinomethyl)benzyl)oxy)-1-oxoisoindolin-2-yl)piperidine-2,6-dione

(3S)-3-[7-[[4-(morpholin-4-ylmethyl)phenyl]methoxy]-3-oxo-1H-isoindol-2-yl]piperidine-2,6-dione

8/13/2026, APPROVAL 2026, FDA 2026, Zenbexus, cc-220, cc 220, 8V66F27X44, 79L3645KFI

To be used in combination with daratumumab and hyaluronidase-fihj and dexamethasone for adults with multiple myeloma who have received at least one prior line of therapy, including a proteasome inhibitor and an immunomodulatory agent

Iberdomide is a modulator of the E3 ubiquitin ligase complex containing cereblon (CRL4-CRBN E3 ubiquitin ligase), with immunomodulating and pro-apoptotic activities. Upon administration, iberdomide specifically binds to the cereblon (CRBN) part of the ligase complex, thereby affecting the ubiquitin E3 ligase activity, and targeting certain substrate proteins for ubiquitination. This induces the proteasome-mediated degradation of certain transcription factors, including Ikaros (IKZF1) and Aiolos (IKZF3) which are transcriptional repressors in T-cells. This leads to a reduction of their protein levels, and the modulation of the immune system, including activation of T-lymphocytes. In addition, this leads to a downregulation of other proteins, including interferon regulatory factor 4 (IRF4), which plays a key role in the proliferation of certain cancer cell types. CRBN, the substrate recognition component of the E3 ubiquitin ligase complex, plays a key role in the ubiquitination of certain proteins.

Iberdomide, sold under the brand name Zenbexus, is an anti-cancer medication used for the treatment of multiple myeloma.[1] It is a cereblon-modulating protein degrader[1] and a thalidomide analog.[2]. It is taken By mouth.[1]

Iberdomide was approved for medical use in the United States in August 2026.[3]

Medical uses

Iberdomide is indicated in combination with daratumumab, hyaluronidase, and dexamethasone for the treatment of adults with multiple myeloma who have received at least one prior line of therapy including a proteasome inhibitor and an immunomodulatory agent.[3]

Society and culture

Legal status

Iberdomide was approved for medical use in the United States in August 2026.[12] The U.S. Food and Drug Administration (FDA) granted the application for iberdomide priority review, breakthrough therapy, and orphan drug designations.[3]

Names

Iberdomide is the international nonproprietary name.[13]

Abstract

The PI3K/Akt signaling pathway is a key pathway in cell proliferation, growth, survival, protein synthesis, and glucose metabolism. It has been recognized recently that inhibiting this pathway might provide a viable therapy for cancer. A series of bis(morpholino-1,3,5-triazine) derivatives were prepared and optimized to provide the highly efficacious PI3K/mTOR inhibitor 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea 26 (PKI-587). Compound 26 has shown excellent activity in vitro and in vivo, with antitumor efficacy in both subcutaneous and orthotopic xenograft tumor models when administered intravenously. The structure−activity relationships and the in vitro and in vivo activity of analogues in this series are described.

Abstract

A new, practical, and convergent synthetic route of gedatolisib, an antitumor agent, is developed on a hectogram scale which avoids the Pd coupling method. The key step is adopting 6-(4-nitrophenyl)-1,3,5-triazine-2,4-diamine and 2,2′-dichlorodiethyl ether to prepare the key 4,4′-(6-(4-nitrophenyl)-1,3,5-triazine-2,4-diyl)dimorpholine in 77% yield and 98.8% purity. Gedatolisib is obtained in 48.6% yield over five simple steps and 99.3% purity (HPLC). Purification methods of the intermediates and the final product involved in the route are given.

Ezobresib is an investigational new drug that has been evaluated for the treatment of cancer. It inhibits Bromodomain and Extra-Terminal domain (BET) proteins, with potential antineoplastic activity.[1] Developed by Bristol Myers Squibb, this therapeutic agent has been studied for its efficacy in treating various cancers, including solid tumors and hematological malignancies.[2] Despite showing promise in early-phase clinical trials, recent developments suggest that Bristol Myers Squibb has decided to discontinue further development of ezobresib.[3]

BMS-986158 is under investigation in clinical trial NCT02419417 (Study of BMS-986158 in Subjects With Select Advanced Cancers).

Ezobresib is an inhibitor of the Bromodomain (BRD) and Extra-Terminal domain (BET) family of proteins, with potential antineoplastic activity. Upon administration, ezobresib binds to the acetyl-lysine binding site in the BRD of BET proteins, thereby preventing the interaction between BET proteins and acetylated histones. This disrupts chromatin remodeling and prevents the expression of certain growth-promoting genes, resulting in an inhibition of tumor cell growth. BET proteins (BRD2, BRD3, BRD4 and BRDT) are transcriptional regulators that bind to acetylated lysines on the tails of histones H3 and H4, and regulate chromatin structure and function; they play an important role in the modulation of gene expression during development and cellular growth

Selective estrogen receptor degraders (SERDs) bind to the estrogen receptor (ER) and downregulate ER-mediated transcriptional activity. The degradation and downregulation caused by SERDs can be useful in the treatment of various proliferative immune mediated disorders, cell proliferation disorders, including cancers such as breast cancer, ovarian cancer, endometrial cancer, prostate cancer, uterine cancer, gastric cancer, and lung cancer as well as mutations due to emerging resistance. Some small molecule examples of SERDs have been disclosed in the literature (see, e.g., WO2005073204, WO2014205136, and WO2016097071). Nonetheless, there is a need for new SERDs to treat ER-positive cancers, such as breast cancer, gastric cancer, and/or lung cancer.

As described in U.S. Pat. No. 10,654,866 (the ‘866 patent) a series of SERDs of the following formula have been discovered, along with pharmaceutically acceptable salts thereof:

wherein one of R1 and R2 are independently Cl, F, —CF3, or —CH3, and the other is H.

Oritinib represents a third-generation EGFR TKI engineered by Nanjing Sanhome Pharmaceutical. This agent specifically targets both EGFR-sensitizing mutations and the T790 M resistance mutation,
thereby addressing resistance mechanisms linked to prior-generation EGFR-TKIs. In 2024, the NMPA granted approval for Oritinib to treat adult patients with locally advanced or metastatic NSCLC who have experienced disease progression during or following EGFR-TKI therapy and possess confirmed EGFR T790 M mutation-positive status. The mechanism of action of Oritinib involves irreversible binding to mutant EGFR, including the T790 M variant, which in turn suppresses down stream signaling pathways responsible for tumor cell proliferation and survival [28]. The mechanism of Oritinib effectively inhibits tumor growth in patients harboring T790M-mediated resistance to first- and second-generation EGFR-TKIs. Clinical efficacy was established in a Phase II trial (NCT03823807) enrolling patients with EGFR T790 Mmutation-positive NSCLC who had experienced disease progression following prior EGFR-TKI therapy. This study documented an ORR of 60.5 % and a median PFS of 9.6 months, highlighting substantial anti
tumor efficacy in this specific patient cohort. In terms of safety, Oritinib exhibited favorable tolerability. The predominant treatment-related adverse events were rash, diarrhea, and elevated liver enzymes, pri
marily of mild (Grade 1) or moderate (Grade 2) severity. No dose-limiting toxicities were encountered, and the overall safety profile aligned with those observed for other third-generation EGFR-TKIs [29].
The synthetic route of Oritinib Mesylate, shown in Scheme 7, begins with nucleophilic substitution reaction between Orit-001 and Orit-002 to yield Orit-003, which further reacts with Orit-004 via nucleophilic substitution to produce Orit-005 [30]. Orit-005 subsequently undergoes another nucleophilic substitution with Orit-006 to generate Orit-007. Following this, Orit-007 is reduced to form Orit-008. Finally, an amidation reaction between Orit-008 and Orit-009 affords Oritinib.

Befotertinib (D-0316) is an orally active EGFR tyrosine kinase inhibitor. Befotertinib can inhibit the proliferation of tumor cells. Befotertinib can be used in the research of EGFR T790M-positive non-small cell lung cancer (NSCLC).

Befotertinib is an orally available inhibitor of the epidermal growth factor receptor (EGFR) mutant form T790M, with potential antineoplastic activity. Upon administration, befotertinib specifically binds to and inhibits EGFR T790M, a secondarily acquired resistance mutation, which prevents EGFR-mediated signaling and leads to cell death in EGFR T790M-expressing tumor cells. Compared to some other EGFR inhibitors, befotertinib may have therapeutic benefits in tumors with T790M-mediated drug resistance. EGFR, a receptor tyrosine kinase that is mutated in many tumor cell types, plays a key role in tumor cell proliferation and tumor vascularization.

Befotertinib (Surmana). Befotertinib (17), an oral, highly selective, third generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) developed by Betta Pharmaceuticals and InventisBio, was approved in China in May 2023 for the second-line treatment of patients
with locally advanced or metastatic nonsmall cell lung cancer (NSCLC) with positive EGFR T790 M mutation who have disease progression on previous EGFR TKI therapy. 140 139 NSCLC
has a high incidence and disease burden in China, which has spurred the development of multiple EGFR TKIs by Chinese companies.
Achromatography-free process route to befotertinib (17) has been reported in the patent literature by researchers at InventisBio (Scheme 29), although details about scale and yields were not provided.
141 142 The reaction sequence closely follows that of osimertinib, a third generation EGFR inhibitor
that was first approved in 2015 and was covered in our previous review.
Osimertinib and befotertinib share a common backbone, differing only in N-substitution on the indole ring.
Friedel−Crafts arylation of 1H-indole with 2,4-dichloropyrimidine (17.1) gave the 3-pyrimidinyl indole 17.2. The trifluoroethyl moiety in indole 17.4 was introduced via Nalkylation of 17.2 with triflate 17.3. This was followed by an SAr reaction with nitroaniline 17.5 to provide amino pyrimidine 17.6. Next, N,N,N′-trimethylethylenediamine (17.7) displaced the electrophilic aryl fluoride in an SNArreaction to generate intermediate 17.8. The acrylamide moiety was installed using a three-step sequence: hydrogenolytic
reduction of the nitro group to the corresponding aniline, acylation with 3-chloropropanoyl chloride, and immediate elimination to the acrylamide. Mesylate salt formation and crystallization furnished befotertinib mesylate (17) in eight steps from 17.1.

Zongertinib is an orally bioavailable inhibitor of the receptor tyrosine kinase human epidermal growth factor receptor 2 (HER2; ErbB2; HER-2), with potential antineoplastic activity. Upon oral administration, zongertinib covalently binds to and inhibits the activity of both wild-type and HER2 mutants, including HER2 mutants with exon 20 insertion (ex20ins) mutations. This prevents HER2-mediated signaling and may lead to cell death in HER2-expressing tumor cells. HER2, a receptor tyrosine kinase overexpressed on a variety of tumor cell types, plays an important role in tumor cell proliferation and tumor vascularization.

Example
        The following examples further illustrate but do not limit the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, all of which are included in the scope of protection of the present invention.
        The specific conditions not disclosed in the experimental methods of the following examples can be selected according to conventional methods and conditions, or according to the product instructions.
        Unless otherwise specified, “room temperature” in the following examples refers to 20°C to 25°C. The term “h” used herein refers to hours.
        Example 1
        Step 1:
        
        Under nitrogen, N-methylpyrrolidone (137.6 g) was heated to 30-35°C to obtain the compound of Formula 1 (14.4 g, 1.3 eq) and the compound of Formula 2 (19.14 g, 1 eq). Bis(triphenylphosphate)palladium dichloride (0.46 g, 0.01 eq) and cuprous iodide (0.113 g, 0.01 eq) were added sequentially. Triethylamine (9.45 g, 1.5 eq) was then added under nitrogen. The reaction mixture was heated to 65-75°C and maintained at this temperature for 2 hours. The reaction process was monitored by liquid chromatography-mass spectrometry. The reaction was terminated when the content of the compound of Formula 2 was ≤0.1%. After completion of the reaction, the reaction solution was cooled to 35-45°C and N-acetyl-L-cysteine (1 g, 0.1 eq) was added directly. The reaction was stirred for 4-5 hours. The resulting product was cooled to room temperature, precipitated with water, centrifuged, and washed with pure water to obtain a crude filter cake. The crude filter cake was vacuum-dried and then slurried with a mixture of ethyl acetate and n-heptane (5 mL of the mixed solvent, wherein the volume ratio of ethyl acetate to n-heptane was 1:1) at a rate of 5 mL per gram of crude filter cake. The resulting slurry was vacuum-dried to yield the compound of Formula 3 with a yield of 85.97% and a purity of 98.2%.
        The NMR data for the compound of Formula 3 are as follows : 1 H NMR (400 MHz, d-DMSO): δ ppm: 8.93 (1H, d, J = 2.0 Hz); 8.63 (1H, d, J = 2.0 Hz); 8.49 (1H, s); 8.11 (1H, d, J = 2.0 Hz); 7.92 (1H, dd, J = 1.6 Hz; J = 8.0 Hz); 7.52 (1H, d, J = 8.0 Hz); 3.88 (3H, s); 2.59 (3H, s); 1.65 (9H, s).
        Step 2:
        
        Under nitrogen, methanol (160 g) and water (50 g) were sequentially added to the compound of formula 3 (20 g, 1.0 eq). The reaction system was stirred at reflux for 18 hours with process control. The resulting product was cooled to room temperature and filtered to obtain a filter cake (no drying required). Recrystallization was performed by adding 10 times the mass of the filter cake in methanol. The resulting mixture was stirred at 60-70°C for 8-10 hours, then cooled to 40-50°C and subjected to a gradient cooling process at a cooling rate of 5°C per 1 to 1.5 hours to slowly form a solid precipitate. The resulting mixture was filtered, the filter cake was washed with methanol, and vacuum dried to obtain the compound of formula 4 in a 91% yield and 99.7% purity.
        The NMR data for the compound of Formula 4 are as follows : 1 H NMR (400 MHz, d-DMSO): δ ppm: 8.73 (1H, d, J = 2.0 Hz); 8.52 (1H, t, J = 2.0 Hz); 8.21 (1H, d, J = 2.0 Hz); 8.06 (1H, s); 7.86 (1H, dd, J1 = 2.0 Hz; J2 = 8.0 Hz); 7.49 (1H, dd, J1 = 1.6 Hz; J2 = 7.6 Hz); 3.86 (3H, s); 2.56 (3H, s).
        Step 3:
        
        Under nitrogen, THF (448 mL), compound of formula 4 (29.1 g, 1 eq), and compound of formula 5 (24.6 g, 0.9 eq) were added, stirred, and cooled to -65°C to -60°C. At this temperature, potassium tert-butoxide (19 g x 3) was added in batches every 0.5 h. The reaction process was controlled by liquid phase detection. After 2 hours, the reaction temperature was raised to -5 to 0°C. The reaction solution was washed with purified water, stirred for 0.5-1 hour, washed with brine, and separated to obtain an organic phase. N-acetyl-L-cysteine (11.41 g, 0.7 eq) was added to the organic phase, stirred, washed with brine, neutralized, and concentrated under reduced pressure. The resulting filter cake was washed with purified water and made into a slurry. The resulting product was washed again with purified water and dried under vacuum to obtain compound of formula 6 with a yield of 88.2% and a purity of 98.6%.
        The NMR data for the compound of formula 6 are as follows : 1 H NMR (400 MHz, d-DMSO): δ ppm: 10.53 (1H, s); 8.75 (d, J = 2.0); 8.53 (d, J = 2.4); 8.24 (1H, s); 8.23 (d, J = 2.4); 8.21 (d, J = 1.6); 8.09 (dd, J1 = 1.6; J2 = 8.4); 7.94 (dd, J1 = 2.0; J2 = 8.0); 7.71 (d, J = 8.8); 7.53 (d, J = 8.0); 3.56 (2H, s); 2.59 (3H, s); 2.34-2.35 (8H, m), 2.16 (3H, s).

SYN

Olverembatinib(24) wasdeveloped by Ascentage Pharma as anorally available, third-generation
tyrosinekinase inhibitor (TKI) for the treatment of chronic myeloid leukemia (CML), acute myeloid leukemia, acute lymphoblastic leukemia (ALL), and solid tumors.167 It received its first approval inChina inNovember 2021 and was approved for use in adults with TKI-resistant CML chronicphaseandCML-acceleratephaseharboringtheT315I “gatekeeper” mutation.168 The current mainstay of CML
treatmentiscenteredaroundTKIs;however,resistancetoTKItherapy, often through BCR-ABL1 kinase domain point mutations, remains a challenge for early generation therapies.169Olverembatinibretainsitsefficacybyfunctioningasan ATP-bindingsiteinhibitorofwild-typeBCR-ABL1kinaseand broadly relatedmutants including T315I, which otherwise confers resistance against all first and second generation TKIs.168
Thesynthesisofolverembatinibhasbeenreportedinseveral patents,170−172 aswell as a journal article173 that details the divergentapproachtorelatedanalogues. Inarecentpatent,170 the synthesis of olverembatinib began with a Sonogashira coupling of commercially available alkyne 24.1 with
