Prodrug Activation Strategies in Drug Discovery

A prodrug, also known as a precursor drug, generally refers to a class of compounds that are themselves inactive or have weak activity but, after conversion within a biological organism, […]

Differences Between Protein Degraders and Traditional Small Molecule Drugs

Targeted protein degradation (TPD) is an emerging protein degradation technology in recent decades that utilizes the cell’s own protein clearance mechanisms, such as lysosomal degradation and proteasomal degradation, to degrade target […]

Research Progress of Dual-Loading ADCs

Antibody-drug conjugate (ADC) combines the tumor targeting specificity of monoclonal antibodies and the potent cell killing activity of cytotoxic drugs (warhead/payload), through a carefully designed chemical linker (linker). The two are […]

Self-Replicating RNA

Principles and Applications of Self-Replicating RNA Design

The emergence of RNA synthesis in vitro and in vivo delivery methods has garnered significant attention in the biomedical field, particularly regarding the applications of synthetic mRNA. However, in most biological […]

Advances in Non-Viral Vector Delivery Systems for Nucleic Acid Drugs

Nucleic acid drugs are mainly divided into two major categories: small nucleic acid drugs and mRNA. Small nucleic acid drugs, also known as oligonucleotide drugs, include antisense nucleotides (ASO), small […]

ADC payloads

History of ADC Payloads and Its Pharmacokinetic Profiles

Chemotherapy drugs are an important means of tumor treatment. At present, chemotherapy drugs based on different mechanisms have been developed, which can act on the initial raw materials such as […]

ADC toxicity

Effects of ADC Toxicity and Optimization Strategies

So far, the FDA and EMA have approved six ADC drugs for patients with solid tumors. Fig. 1 depicts the composition of each ADC (targeting antigen, mAb type, payload, and linker), […]

inhibitors

Peptide Covalent Inhibitors Targeting Protein-Protein Interactions

Covalent drugs refer to those drug molecules that form strong bonds with receptors through the formation of covalent bonds. It all began with aspirin in 1899, gained prominence with ibrutinib in […]

ligands in PROTACs

Thalidomide Analogs and Other CRBN Ligands in PROTACs

History of Thalidomide During the 1950s-1960s, thalidomide was widely used as an antiemetic for pregnant women, leading to a tragic outcome with thousands of cases of malformed babies. However, in 1965, […]

Trastuzumab ADC

Review of Structure-Activity Relationship Based on Trastuzumab ADC

Many approaches have been developed to improve the physical/chemical properties, potency and selectivity of antibody-drug conjugates (ADCs). Trastuzumab (Tz), a monoclonal antibody targeting HER2, was approved by the FDA in […]
