Immunomodulatory drugs (IMiDs), such as thalidomide and lenalidomide (Len), are effective drugs for the treatment of multiple myeloma. The combination of SHIN1 and Len can further increase the sensitivity of MM cells to IMiDs. Therefore, this study provides the basis for the exploration of a possible strategy for the SHIN1 and Len combination treatment for MM.

Using a literature search methodology comprising searches of PubMed (unlimited time-frame) and international hematology/oncology conference abstracts (2019-2023) for terms including IKZF1, IKZF3, Ikaros, Aiolos, CELMoD, IMiD, iberdomide, mezigdomide, and MM, this paper reviews the importance of Ikaros and Aiolos in MM, the mechanism of action of the IMiDs and CELMoD agents and their relative potency for targeting Ikaros and Aiolos, and preclinical and clinical data on iberdomide and mezigdomide. Emerging data suggest iberdomide and mezigdomide have promising activity, including in IMiD-resistant settings, and, pending phase 3 findings, may provide additional treatment options for patients with MM.

In addition, pomalidomide only overcomes lenalidomide refractoriness in a subset of patients. We will discuss the biological aspects of these agents, including their mechanisms of action, efficacy, and toxicity profile, and provide a comprehensive review of current literature. Special attention will be paid to ongoing and future clinical trials that provide insights into the potential of these novel therapies in the management of MM.

We adopted BioID2-dependent proximity labelling (BioID2-CRBN) to characterise the CRBN interactome in the presence and absence of various IMiDs and the proteasome inhibitor, bortezomib...Here we identify Non-Muscle Myosin Heavy Chain IIA (MYH9) as a putative CRBN neointeractor that may contribute to the haematological toxicity of IMiDs. These studies provide proof of concept for proximity labelling technologies in the mechanistic profiling of IMiDs and related E3-ligase-modulating drugs.

Furthermore, with the deep penetration of two-photon excitation, Ru-Poma achieved drug-resistant circumvention in a 3D tumor cell model. Thus, we describe the first sample of the CRBN-targeting Ru(II) complex active in PDT.

However, thalidomide and its approved derivatives remain plagued by several shortcomings, such as structural instability and poor solubility. Herein, we present a review of strategies for mitigating these shortcomings and highlight contemporary drug discovery approaches that have generated novel thalidomide analogs with enhanced efficacy as cereblon effectors and/or anticancer agents.

Altogether, compound 1 is a valuable chemical biology tool to study the role of PRC1 in cancer. Importantly, we show that CRBN can be utilized to develop bridged PROTACs, expanding the bridged PROTAC technology for degrading undruggable proteins.

The vast majority of current cereblon (CRBN) ligands is based on the thalidomide scaffold, relying on glutarimide as the core binding moiety...In this new orientation it forms additional hydrophobic interactions and is not available for direct interactions with the canonical neo-substrates. We therefore propose this chemotype as an attractive building block for the design of PROTACs.

Preclinical studies of mezigdomide have demonstrated its anti-proliferative and apoptotic effects in MM, along with its immune-stimulatory effects and its synergistic activity with other antimyeloma agents, including in lenalidomide-/pomalidomide-resistant MM cell lines and mouse xenograft models. Early-phase clinical trial data indicate notable activity in heavily pretreated patients with RRMM, including those with triple-class-refractory disease, together with a tolerable and manageable safety profile. This review summarizes current preclinical and clinical findings with mezigdomide and its potential future roles in the treatment of MM.

Lenalidomide (LEN; a second-generation immunomodulatory drug [IMiD]) has been employed as an additional therapeutic option for ATL since 2017, but its mechanism of action has not been fully proven, and recent studies reported emerging concerns about the development of second primary malignancies in patients treated with long-term IMiD therapy. Finally, a novel cereblon modulator (CELMoD), iberdomide (IBE), exhibited a broader and deeper spectrum of growth suppression to ATL cells with efficient IKZF2 degradation, which was not observed in other IMiD treatments. Based on these findings, our study strongly supports the novel therapeutic advantages of IBE against aggressive and relapsed ATL.

Cereblon-targeting degraders, including immunomodulatory imide drugs lenalidomide and pomalidomide alongside cereblon E3 ligase modulators like iberdomide and mezigdomide, have demonstrated significant anti-myeloma effects...Despite their evident efficacy, approximately 5% to 10% of MM patients exhibit primary resistance to lenalidomide, and resistance commonly develops over time. Understanding the intricate mechanisms of action and resistance to this drug class becomes imperative for refining and advancing novel therapeutic combinations.
