Brief Introduction of ADC Drug Production Technology
Drug-to-antibody ratio (DAR, drug-to-antibody ratio) The number of cytotoxic drugs connected to each antibody is the drug-to-antibody ratio (DAR). When the DAR increases, the drug metabolism rate of ADC drugs increases, the half-life decreases, and the systemic toxicity increases. Ideally, when the DAR is 4, the drug has the highest efficacy. Therefore, in actual production, the drugs with DAR ...

J.Med.Chem publish; Predicting Regioselectivity of AO, CYP, FMO and UGT Metabolism Using Quantum Mechanical Simulations and Machine Learning
Abstract – Unexpected metabolism in modification and conjugation phases can lead to the failure of many late-stage drug candidates or even withdrawals of approved drugs. Thus, it is critical to predict the sites of metabolism (SoM) for enzymes, which are known to interact with drug-like molecules, in the early stages of the research. The study presents methods for predicting the ...
