William Kinney, PhD

Co-Founder, Senior VP, Research & Development

Dr. Kinney is a drug discovery scientist, process development chemist, and entrepreneur with greater than 30 years of experience in large pharmaceutical (Wyeth, Johnson & Johnson), biotechnology (Magainin), and non-profit (Blumberg Institute) research and development.

He has demonstrated expertise in drug design; synthesis; lead optimization of peptides, small molecules, natural products, and cGMP drug development; and is inventor of three molecules that advanced to human clinical trials – Perzinfotel (CNS disorders and pain), Squalamine (oncology and AMD), and Trodusquemine (obesity).  He was the chemistry leader on the initial squalamine IND project team, delivering drug substance to launch a Phase I clinical trial on time and on budget. The squalamine cGMP scale-up campaign required building and leading an internal process group, partnering with analytical chemistry on method development and stability studies, working with multiple domestic and international collaborators, and writing the CMC section of the IND.

In 2000, he joined Johnson & Johnson, where he pursued peptide-mimetic integrin antagonists and urotensin-II receptor modulators for cardiovascular indications.  He also made seminal discoveries with respect to self-assembling collagen-mimetic peptides that stimulate platelet aggregation.

Currently, Dr. Kinney is co-founder and Vice President of Research and Development at Enterin, Inc. where he leads scale-up of drug substance and drug product for the ENT-01 IND for the treatment of Parkinson’s Disease.  His scientific contributions include 80 publications, invited lectures, and oral presentations and inventorship on 42 issued U.S. patents.
