Twenty-nine Methods for Amide Synthesis: Mechanisms, Characteristics, Applications, and Selection

Twenty-nine Methods for Amide Synthesis: Mechanisms, Characteristics, Applications, and Selection

The preparation of amides is one of the most common reactions in organic synthesis and a key reaction for the preparation of peptide drugs and nucleic acid drugs in recent years. […]

Analysis Method for Drug-to-Antibody Ratio (DAR) of Antibody-drug Conjugates

Analysis Method for Drug-to-Antibody Ratio (DAR) of Antibody-drug Conjugates

The Drug-to-Antibody Ratio (DAR) is the most important quality attribute of ADC drugs because it determines the “payload” that can be delivered to tumors, directly impacting safety and efficacy. Here, we […]

RNA-targeted Gene Therapy

RNA-targeted Gene Therapy

In the early 21st century, after the completion of the Human Genome Project, it was discovered that many diseases were caused by gene mutations leading to insufficient expression of functional […]

The Latest Developments in ADC Payloads

The Latest Developments in ADC Payloads

Driven by increasingly mature technologies, ADC payloads have undergone three generations of innovation. In the first generation of ADC drugs, traditional chemotherapy agents such as methotrexate, vincristine, and doxorubicin were used […]

The Magical Biotin

The Magical Biotin

What is Biotin? Biotin, with a molecular weight of 244.31, consists of two cyclic structures. The first ring is the imidazolone ring, the primary site for binding with avidin; the […]

Comparison and Analysis of SMDC, ADC, and DAC

Comparison and Analysis of SMDC, ADC, and DAC

In order to more effectively deliver chemotherapy drugs, Small Molecule Drug Conjugates (SMDC), Antibody Drug Conjugates (ADC), and Degradation Antibody Conjugates (DAC) have been successively explored and developed, enhancing the […]

Preparation Methods of Microspheres

Preparation Methods of Microspheres

There are various techniques for the preparation of microspheres, and the selection of an appropriate method depends on the physicochemical properties of the drug. Currently, the most widely used methods […]

ADCs

Several Ways of Thiol Coupling in ADCs

The popularity of thiol coupling in ADC preparation can be attributed to three factors: It is essential to note that a reduction step is always required before coupling to release […]

What is Peptide Nucleic Acid (PNA)

What is Peptide Nucleic Acid (PNA)?

Peptide Nucleic Acid (PNA) is a synthetic polymer similar to DNA or RNA. PNA can be said to have been born in Denmark, where it was originally developed by Peter E. […]
