The cover of this issue of Trends in Pharmacological Sciences features the work “Molecular Glue Meets Antibody: Next-Generation Antibody–Drug Conjugates” by Yiran Tao, Yuxi Wang, Ying Lu, and Bin Yu.

Research Background

Antibody–drug conjugates (ADCs) have revolutionized the field of oncology by enabling the targeted delivery of cytotoxic therapeutics. However, several persistent limitations continue to restrict the broader therapeutic potential of ADCs, including the limited diversity of payloads. In addition, the emergence of drug resistance mechanisms has created new challenges for the clinical efficacy of ADC-based therapies. To overcome these obstacles, researchers have begun exploring innovative payload strategies, leading to the development of molecular glue–antibody conjugates (MACs). By employing molecular glues as payloads, MACs provide a novel approach to addressing the current limitations of conventional ADCs.

Research Significance

Molecular glue–antibody conjugates (MACs) offer several remarkable advantages and represent a breakthrough advancement in this field. Due to the catalytic and event-driven properties of molecular glues, MACs have the potential to achieve enhanced therapeutic efficacy. Compared with traditional ADCs, MACs may reduce off-target effects, improve treatment safety, and ultimately enhance the therapeutic index. Currently, two MAC candidates have already entered clinical trials, further validating their promising clinical potential. This progress not only introduces new possibilities for cancer therapy, but also offers renewed hope for improving patient outcomes and quality of life.

Research Outlook

This study provides an in-depth discussion of the mechanisms, recent advances, and the potential of molecular glue–antibody conjugates (MACs) to surpass traditional ADCs and molecular glues alone. Despite their exciting promise, MACs still face multiple developmental challenges. Future research should focus on further elucidating their mechanisms of action and optimizing their design and synthesis strategies to improve stability and efficacy. In addition, several critical issues remain to be addressed, such as achieving more precise control over molecular glue release and minimizing immunogenicity. With continued scientific advances and technological innovation, MACs are expected to play an increasingly important role in cancer therapy, paving the way for more effective anticancer treatments and driving the next generation of oncology therapeutics.

Cover Design Concept

• The cover design closely revolves around the central theme of the article — molecular glue–antibody conjugates (MACs). Through a microscopic perspective, the artwork visualizes biomolecular interactions at the cellular level and intuitively illustrates the mechanism of action of MACs. The image depicts the conjugation between antibodies and molecular glue payloads, as well as their interactions on the cell surface, highlighting the core concept of MACs as an emerging therapeutic strategy. This visually compelling presentation draws readers’ attention to this innovative research field.

• The overall color palette features a deep brown background, creating a sophisticated and professional scientific atmosphere while enhancing the visibility of the molecular structures in the foreground. The antibody components are rendered in red to emphasize their critical role as delivery carriers within MACs, while the molecular glue payloads are highlighted in green to underscore their functional importance. Cell membranes and associated biological structures are represented using purple, blue, and orange tones, adding visual depth and improving scientific clarity. This rich combination of colors not only makes the composition more dynamic, but also helps readers quickly distinguish and understand the various molecular components.

• The overall artistic style adopts a realistic 3D rendering approach, delivering a strong sense of advanced technology and modern scientific aesthetics. Through detailed modeling and lifelike material rendering, the microscopic biomolecular world is transformed into an intuitive and highly visualized representation, aligning with the precision, professionalism, and visual impact expected from scientific journal covers. Ultimately, the cover design received high recognition from both the research team and the journal editors, and was successfully selected for publication as the journal cover artwork.
