Introduction Degrader-Antibody Conjugates (DAC) are a novel entity that combines the payload of Protein Degradation Targeting Chimeras (PROTAC) with monoclonal antibodies through a type of chemical linker (DAC =PROTAC + ADC). This article collects several examples of DAC from scientific and patent literature and documents specific challenges associated with DAC construction. Overall, these examples indicate … Read more
DAC (Digital-to-Analog Converter) and ADC (Analog-to-Digital Converter) are essential components for converting between digital and analog signals, widely used in electronic systems for various applications such as digital signal processing, data acquisition, and control. So, do you know how to implement DAC and ADC? Methods for Implementing DAC 1. Resistor Network A resistor network is … Read more
Currently, there are 15 ADC drugs approved globally, among which 6 ADC drugs have been approved in China, namely Trastuzumab emtansine, Brentuximab vedotin, Trastuzumab deruxtecan, Vidofludimus, Gemtuzumab ozogamicin, and Sacituzumab govitecan. This article provides a brief summary based on the currently approved ADC drugs worldwide, the types of tumors they are suitable for, and how … Read more
1. Mechanism of ADC Action Antibody-drug conjugates (ADC) (Click to enter the database to search for global ADC drug information) enter the body, the antibody part binds to the targeted antigen on the surface of tumor cells, tumor cells will endocytose the ADC molecule. Among them, some can bind to Fc receptors in the endosome, … Read more
In the early 20th century, Paul Ehrlich first proposed the famous “magic bullet” theory, suggesting that drugs could be developed to specifically target pathogenic structures without harming normal tissues and cells. Subsequently, the concept of antibody-drug conjugates (ADCs) was introduced, combining the target specificity of monoclonal antibodies with the anti-tumor properties of cytotoxic molecules. After … Read more
As of now, the toxicity and prevention measures of ADC in solid tumors are known as follows: ① The indications for ADCs are rapidly expanding, gradually shifting from late-stage to early-stage, and from single therapy to combination strategies. ② The toxicity characteristics of most ADCs are similar to the cytotoxicity of their payloads. ③ Certain … Read more
▎This article is contributed by Ying’en Biotech (slightly edited) Since the first antibody-drug conjugate (ADC) was approved for the treatment of acute myeloid leukemia in 2000, after more than twenty years of exploration and development, 14 ADC drugs have been successfully approved for clinical treatment of tumors. In August 2022, the FDA announced the accelerated … Read more
Introduction Antibody-drug conjugates (ADC) are comprised of monoclonal antibodies that target specific antigens linked to small molecule cytotoxic drugs via a linker, combining the powerful killing effects of traditional small molecule chemotherapy with the tumor-targeting properties of antibody drugs. Since the first ADC (Gemtuzumab-ozogamicin (trade name: Mylotarg)) was approved for the treatment of CD33-positive acute … Read more
Last week, while introducing the “Breakthroughs and Innovations in Lung Cancer Treatment” from the “AACR 2021 Annual Report on Anti-Cancer Progress”（>> Click to review）, I mentioned a popular research topic—Antibody-Drug Conjugates (ADCs), which saw two new ADCs approved and two ADCs expanding their indications in 2021. Some readers expressed a desire to learn more about … Read more
The development of ADC drugs has not been smooth sailing, with nearly 100 years of history since the concept of the “magic bullet” was proposed, but ultimately, the clouds have parted to reveal the moon. DS8201 has redefined ADC, but it is not the end of ADC drugs, rather a new beginning. A comprehensive understanding … Read more
