He is the author or co-author of more than 400 articles and co-editor of nine books. He is among the 300 most cited scientists worldwide from 1965-1978 and among the 500 most cited scientists 1973-1982. He has lectured extensively in the United States and 26 foreign countries.


Development of a system of analysis useful for Drug Discovery and the reduction of Adverse Drug Reactions (ADR): The system utilizes a comprehensive library of monoclonal antibodies specific and inhibitory to each of the human liver cytochrome P450s responsible for the metabolism of drugs and non-drug xenobiotics. The P450s also metabolize certain classes of endobiotics such as steroids, prostaglandins and arachidonic acid. The single or combinatorial use of the monoclonal antibodies (MAbs) "reaction phenotype" that is, determine the quantitative metabolic contribution of each cytochrome P450 isoform to a substrates metabolism. Thus, the MAb system identifies drugs or metabolic pathways catalyzed by a single P450 and those catalyzed by two or more cytochrome P450s. The drugs metabolized by a single P450 can be used as markers for in vivo analysis of a patients cytochrome P450 phenotype. The MAb system also identifies drugs metabolized by a polymorphic P450 and drugs metabolized by a common P450 which may result in drug-drug toxic reactions. The library of monoclonal antibodies are specific and inhibitory to human cytochrome P450 1A1, 1A2, 2A6, 2B6, 2C8, 2C9, 2C19, 2D6, 2E1, and 3A4. The MAb system is a new, specific and precise method for quantitating drug metabolism catalyzed by each cytochrome P450. The MAb system can also analyze New Chemical Entities (NCEs) for Drug Discovery as well as currently used drugs, for the reduction of drug toxicity due to Adverse Drug Reactions (ADR). The MAb system should thereby yield information for the improvement of Drug Therapeutics.
