Applications of macrocyclic molecules in cancer therapy: Target cancer development or overcome drug resistance

Applications of macrocyclic molecules in cancer therapy: Target cancer development or overcome drug resistance
2023-11-30
(Press-News.org)

This review was designed by Professor Xiaoling Song and Professor Biao Jiang and written by Pr. Xiaoling Song and a Ph.D. student, Yifan Wu (Shanghai Institute for Advanced Immunochemical Studies, ShanghaiTech University) to summarize the application of macrocyclic molecules in cancer treatment. Macrocyclic compounds are cyclic molecules with a structure of 12 or more atoms. In the past decades, macrocycles have received increasing attention in drug development. The U.S. Food and Drug Administration has approved several macrocyclic drugs for cancer therapy. However, the importance of this class of cancer drugs is still not widely known.

Song and Wu comprehensively summarized the applications of both FDA-approved macrocyclic drugs in the past 15 years and those promising macrocyclic small molecules currently under development for cancer therapy, providing strong evidence for the applications of macrocyclic compounds in cancer treatment (Figure). First, macrocyclic molecules can target proteins critical for tumorigenesis or cancer development. Macrocyclic compounds can block nearly 80% of cancer's signature characteristic events to control cancer occurrence and progression, suggesting a space for using macrocyclic compounds in cancer therapy. Secondly, macrocyclic compounds can effectively overcome drug resistance caused by on-target mutations in targeted cancer therapy. Small compact macrocyclic molecules can enter the binding pocket, bind to mutant proteins, and inhibit their activities, especially those with resistant mutations around the binding pocket. These macrocyclic compounds developed recently for overcoming cancer drug resistance include the pyrazole- or pyrimidine-based TRK inhibitor Selitrectinib and the next-generation ROS1/ NTRK inhibitor Repotrectinib (TPX-0005).

Additionally, the authors reviewed the ongoing clinical trials for these novel macrocyclic drug candidates, and some of them have shown excellent therapeutic efficacy. For example, recent data from the latest Phase 1/2 clinical trial showed that first-line use of repotrectinib in ROS1-positive TKI-naïve lung cancer patients resulted in long-term progression-free survival (PFS) of 35.7 months (TRIDENT-1, NCT03093116. Byoung Chul Cho, et al. 2023 WCLC. OA 03.06).

Finally, Song and Wu provided novel insights into macrocyclic molecular drugs regarding their future directions, limitations, and combinational therapy with other drugs in clinics. This comprehensive review is beneficial for the development of novel cancer treatment strategies.

2023-11-30
In his Value Creation project in Cell Ag class, Tufts senior Adham Ali faced an intriguing assignment: work with a group of peers to design a product that uses cellular agriculture (or cell ag, for short) to make life easier for consumers. Majoring in biochemistry, Ali took the class as part of his minor in cell ag—a minor he registered for only this semester, because it’s brand-new at Tufts. It’s also the world’s first and only undergraduate degree in the field. Usually used as part of a nascent—and rapidly growing—field that cultivates lab-grown meat from cells in bioreactors, the processes of cellular agriculture ...

Scientists create framework to guide development and assessment of urban climate action plans

Scientists create framework to guide development and assessment of urban climate action plans
2023-11-30
With the world projected to be highly urbanized by 2050, cities are encouraged to take urgent climate actions to mitigate and adapt to the threats of climate change. As climate change intensifies and urbanization increases rapidly, local governments are expected now more than ever to lead climate action planning. However, studies show the limitations of the existing climate action plans (CAPs). So scientists from Hiroshima University have created an Urban Climate Action Planning (UCAP) framework to guide the development of urban CAPs and support the assessment of the level of suitability of these plans. Their work is published ...

A new bacterial species from a hydrothermal vent throws light on their evolution

A new bacterial species from a hydrothermal vent throws light on their evolution
2023-11-30
A new bacterial species discovered at the deep-sea hydrothermal vent site ‘Crab Spa’ provides a deeper understanding of bacterial evolution. Deep-sea hydrothermal vents are hot springs on the ocean floor. Sea water penetrates into the ocean crust, becomes heated, and rises to the seafloor surface carrying dissolved nutrients. Around these vents, far from any sunlight, vibrant biological communities are found. Here, microbes play the role of primary producers through chemosynthesis—similar to the role that plants play on land through photosynthesis. Researchers at Hokkaido University, in collaboration with colleagues at Woods ...

Social media posts that promote tobacco are increasing, AI detection technology finds

2023-11-30
When teenagers and young adults see pro-tobacco content on social media, they face higher risks. They are more likely to report using tobacco products such as e-cigarettes (also called vapes), more likely to start using those products for the first time and less likely to view them as harmful. Algorithms programmed to automatically remove tobacco ads are designed to protect youth—but they don’t always work or are not implemented well enough by social media platforms, according to Julia Vassey, MPH, a health behavior researcher in the department of population ...

Identifying Australia's most elusive birds

Identifying Australias most elusive birds
2023-11-30
University of Queensland scientists have analysed more than 3.8 million volunteer hours of birdwatching data to identify Australia’s most elusive species. Louis Backstrom from UQ’s School of the Environment led the research and said the Coxen’s fig-parrot was the bird that was most elusive to Australian birdwatchers, based on the data found in the eBird and Birdata databases. “Coxen’s fig-parrots are small, dumpy, green parrots with very short tails, and historically they were scattered in rainforests between Bundaberg in Queensland and the Hastings River in New South Wales,” Mr ...

Air pollution from fossil fuel use accounts for over 5 million extra deaths a year

2023-11-30
Air pollution from using fossil fuels in industry, power generation, and transportation accounts for 5.1 million extra deaths a year worldwide, finds a new modelling study published by The BMJ today. This equates to 61% of a total estimated 8.3 million deaths worldwide due to ambient (outdoor) air pollution from all sources in 2019, which could potentially be avoided by replacing fossil fuels with clean, renewable energy sources. These new estimates of fossil fuel-related deaths are larger than most previously reported values ...

Social media use linked to risky health behaviors in young people

2023-11-30
Social media use is associated with risky health behaviours in young people including increased alcohol, drug and tobacco use, anti-social behaviour, risky sexual behaviours and gambling, finds a review of the latest evidence published by The BMJ today. Exposure to risky health behaviour content on social media such as alcohol advertising had the strongest evidence of harm, particularly in relation to alcohol use and unhealthy eating. The researchers say further research is needed to establish causality, understand effects on ...

Actively monitoring cervical lesions linked to heightened long term risk of cervical cancer

2023-11-30
Actively monitoring abnormal cells (lesions) that line the cervix rather than removing them straight away is associated with an increased long term risk of cervical cancer, suggests a study published by The BMJ today. The researchers stress that the absolute risk of cervical cancer remains low, but the results show that compared with immediate treatment, active surveillance was associated with a nearly fourfold higher risk of cervical cancer 20 years after diagnosis. Cervical intraepithelial neoplasia (CIN) refers to abnormal changes of the cells that line the cervix. CIN is divided into grades - CIN1, 2 or 3. The higher the number, ...

Internet is fuelling new wave of misogyny, says linguistics expert

2023-11-30
Society has gone backwards in its treatment of women with the internet fuelling new forms of misogyny, according to the author of a new book. Linguist and researcher Deborah Cameron says that prejudice, discrimination and abuse should not be regarded as yesterday’s problems. Rather than fading away in the twenty-first century, they have evolved in ways that reflect today’s conditions, her research suggests. Her book Language, Sexism and Misogyny analyses the way sexism and misogyny are expressed today in advertising and media, drawing on evidence from academic research to provide a comprehensive ...
