Chunying Gao, Ph.D.

Drug transporters play a key role in the absorption, distribution, metabolism, elimination and toxicity (ADME-Tox) of many drugs by controlling the entry or exit of drug molecules into and out of tissues or organs. Due to the importance of drug transporters in these processes and the potential drug-drug interactions among drug molecules on these transporters, in vitro transport studies on a standard panel of drug transporters are recommended by the FDA, EMA, and PDMA regulatory agencies to evaluate the potential interactions as substrates and/or inhibitors among the investigational drugs. The current panel includes P-gp, BCRP, OATP1B1, OATP1B3, OAT1, OAT3, OCT2, MATE1 and MATE2-K; although regulatory agencies are routinely requesting data on additional transporters outside of the current group. 

According to the FDA guidance,[1] several in vitro models are recommended for each transporter:

ABC Transporters

BCRP, P-gp

Caco-2 cells, commercial or in-house membrane vesicles, knock-out/down cells, transfected cells (MDCK, LLC-PK1, etc.)

SLC Transporters


Hepatocytes, transfected cells (CHO, HEK293, MDCK, etc.)


Transfected cells (CHO, HEK293, MDCK, etc.)


Commercial or in-house membrane vesicles, transfected cells (CHO, HEK293, MDCK)


Alliance Pharma has established a set of cell- or membrane vesicle-based assays to support filing packages for the studies recommended by regulatory agencies. For ABC transporters, a membrane vesicle assay (for P-gp and BCRP) and MDR1/MDCK bidirectional permeability assay (for P-gp) has been established. For SLC transporters, an assay platform based on transiently transfected HEK293 cells has been optimized and validated, and can be used for both screening of substrate/inhibitor and Km/IC50 determination.

3 Essential Features of Mass Spectrometry That Every Bioanalytical Scientist Needs to Understand

May 31, 2017 11:39:55 AM / by Dr. Mitch Johnson


Scientists who specialize in developing mass spectrometric methods know that the methods must be individually tailored to successfully support a pivotal clinical trial or to provide bioanalytical support along any phase of the drug development process. A specific mode of mass spectrometry called multiple reaction monitoring (MRM) is a powerful tool because it uses multiple mass spectrometers in tandem to increase sensitivity and selectivity of analysis, generating the most reliable data. Read on to find out why this matters to experts in the fields of pharmacokinetics, bioequivalence, toxicity, and bioanalysis.

Extreme Sensitivity

Mass spectrometry has the ability to accurately determine concentrations of biomarkers present in human matrices down to nanomolar levels. D-erythro-Sphingosine-1-phosphate (S1P) is a biomarker for certain diseases such as atherosclerosis and cancer.

Method Development and Validation for the Quantification of D-erythro-Sphingosine-1-phosphate (S1P) in Human Plasma Using LC-MS/MS

Versatility and Customization

Instrumentation techniques are customizable. Liquid chromatography tandem mass spectrometry has the ability to monitor several different classes of compounds. There are intricate parameters of mass spectrometry that can be optimized for every study. See below how LC-MS/MS techniques have been used to analyze compounds like cholesterol and ManNAc, which are endogenously present in plasma, and goserelin, a synthetic hormone used to treat prostate and breast cancer.

Method Development and Validation for the Quantitation of ManNAc in Human Plasma Using HILIC LC‑MS/MS

A Rapid and Sensitive Method for the Quantification of Goserelin in Human Plasma Using HPLC-MS/MS


By coupling liquid chromatography with mass spectrometry, concentrations of several compounds in a sample can be achieved in a run as short as 3 minutes. Whether you are interested in analyzing several different drugs or a parent compound and its metabolites, it can be done in the same run making study conduct very efficient.
