BALTIMORE--(BUSINESS WIRE)--Arginetix, Inc. today announced it has closed a $10.75 million Series A financing. The company is developing small molecule inhibitors of the enzyme arginase for the treatment of endothelial dysfunction, including pulmonary arterial hypertension, atherosclerosis and asthma.

The financing was co-led by Quaker BioVentures and MedImmune Ventures, a wholly owned venture capital fund of the AstraZeneca Group. Maryland Health Care Product Development Corp., Osage University Partners, Red Abbey Venture Partners, and company co-founder Acidophil LLC also participated in the round.

Arginetix will utilize this financing for further discovery and to continue development of its first-in-class arginase inhibitors for cardiovascular and pulmonary indications. The company's scientific foundation is based on licensed intellectual property of its scientific co-founders, David Christianson, Ph.D. at the University of Pennsylvania and Dan Berkowitz, M.D. at The Johns Hopkins University.

“This financing is an important endorsement for the potential for Arginetix’ discovery and development programs,” said Gary Lessing, CEO and co-founder. “The company is fortunate to be working with a talented and experienced group of investors, including both traditional and corporate-based life sciences firms. Their expertise in the discovery and development of drugs and their track record at building world-class companies will be invaluable to Arginetix’ continued success.”

“Arginetix is pursuing major clinical opportunities using their technology for patients with cardiovascular and pulmonary diseases. The company’s recent research has added further validation for this important innovation,” says Dr. Geeta Vemuri, partner at Quaker BioVentures.

“Arginase appears to be an attractive target with therapeutic potential in a wide range of cardiovascular and pulmonary indications. We are pleased to support their development efforts through this investment and look forward to working with the management team,” says Eva M. Jack, Managing Director at MedImmune Ventures.

About Arginetix

Arginetix is a biopharmaceutical company dedicated to developing and commercializing novel therapeutic small molecule inhibitors of arginase. Arginase is an enzyme that competes with endothelial Nitric Oxide Synthase (eNOS) for the use of the common substrate L-arginine. Elevated Arginase limits L-arginine available for eNOS resulting in both a reduction in Nitric Oxide (NO) production (reducing signaling critical for normal function) as well as eNOS "uncoupling" leading to the production of damaging reactive oxygen species (ROS). Further, arginase also leads to the production of ornithine which increases polyamine, stimulating cell division, contributing to hyperplasia and fibrosis. Together the decrease in NO, the increase in ROS and the increase in ornithine are major causes of endothelial dysfunction. Indications include Pulmonary Arterial Hypertension, asthma, atherosclerosis and other diseases of endothelial dysfunction.
