RESEARCH

The Kulp laboratory accesses two extraordinary resources at the center:  The Blumberg’s Natural Products Discovery Institute (NPDI), which houses a vast natural products collection (former Merck and Schering Plough Collection), and the Baruch S. Blumberg Institute’s faculty that developed world class assays for the hepatitis B virus (HBV) and hepatocellular carcinoma (liver cancer). The U.S. Natural Product Library has a track record of yielding novel bioactive compounds. Some have led to “blockbuster” drugs such as Primaxin®, Mevacor®, Ivomec®, and Cancidas®. Indeed, natural products are the source of 50% of marketed drugs. One goal of the lab is to identify new natural products for the treatment of hepatitis B that specifically target unique points in the viral life cycle including cccDNA silencing.  To achieve a functional cure for hepatitis B, or at least a sustained virological response without treatment, will require either (i) suppression of the integrated DNA (cccDNA) or (ii) a multi-target approach with the outcome of a prolonged virological suppression. The end products of the research will be novel natural products that are effective against the HBV and could be used in combination.

Another project in the Kulp lab is aimed at determining the basis for the selectivity of compounds targeting of liver cancer cells versus non-liver cancer cell lines, in tissue culture. The compounds are selectively toxic to HepG2, Huh7 and other liver cancer lines, relative to “non-cancerous” liver lines THLE2, PH5CH and even more than 20 other cancer lines that are of other organs.

Dr. Kulp’s background is in the field of bioorganic chemistry with specialization in (i) protein nuclear magnetic resonance (NMR) structure determination, (ii) computational methods for studying protein structure, (iii) synthetic peptide chemistry, and (iv), computer-aided drug design with a specialty focus on computational fragment-based methods. His Ph.D. work, in part, concentrated on stabilizing a-helical peptides for development as a new class of drug molecules and the study of peptide/protein structure in solution and on solid surfaces by NMR. During his postdoctoral training at the Naval Research Laboratory, he developed peptide nanopores as stochastic sensing elements and patented a new class of b-helical peptide architectures. After completing his postdoctoral fellowship, Dr. Kulp was hired as a federal staff scientist where he helped develop a program to study biointerfaces. He chose to leave the Navy and follow his research interests in therapeutic discovery. In 2010, Dr. Kulp joined BioLeap, a small business that specializes in protein-protein interactions and that had a proprietary fragment-based computational chemistry software platform. He participated in development of novel inhibitors for DHFR, PCSK9, 11b-HSD, and recA. During that time, he integrated molecular dynamics and docking software into BioLeap’s proprietary fragment-based discovery platform. From 2013 to 2014, Dr. Kulp was the project leader for BioLeap’s PCSK9 program, which consisted of modeling (BioLeap), assays (Broad Institute of MIT and Harvard), and chemical synthesis (WuXi and BioDuro).  In 2014, Dr. Kulp founded Conifer Point Pharmaceuticals as a computational consulting company to help accelerate medicinal chemistry projects and increase customer success in: hit identification, lead qualification/optimization, and likelihood of grant awards, attracting investment funding, or licensing/collaboration opportunities. Dr. Kulp joined the Blumberg Institute in 2013 as an Assistant Professor.

In addition to his active investigation program, Dr. Kulp, as Director of Academics, oversees educational training at the institute. This includes high school programs, college internships, MS and PhD degrees, post-doctoral training, and doctor of medicine education.
