Signum Biosciences, Inc., ROHTO Pharmaceutical Co., Ltd. Alliance Brings Unprecedented Momentum to Signal Transduction

PRINCETON, N.J., Sept. 17 /PRNewswire/ -- In what promises to be a new era in skincare marketing, Signum Biosciences, a private biotechnology company with an extensive program to develop Signal Transduction Modulation (STM) anti-inflammatory molecules, has signed investment and licensing agreements with Rohto Pharmaceutical Co., Ltd. of Osaka, Japan, a publicly traded manufacturer and marketer of skincare, pharmaceutical and other healthcare related products

The agreements, which provide Signum with combined upfront license fees and investment funds in the seven figures, give Rohto a non-exclusive right to develop and sell products in Japan that contain Signum's anti-inflammatory compound Arazine, the lead molecule involving the company's signal transduction modulation technology.

The parties have agreed to immediately enter negotiations for an exclusive license for the Japanese market. Rohto and Signum also have undertaken a broad R&D collaboration to develop an array of Arazine based products that draw on the compound's triple-action capabilities.

The science of staying healthy comes to skin care.

Arazine works with the body's cellular management systems in three distinct ways:

It blocks inflammation and neutrophil infiltration in chronic redness, acne skin irritation, and other skin conditions by modulating GPCR signal transduction pathways.

It acts as an antioxidant to neutralize free radicals and prevent UV damage, cellular degeneration and production of chemicals that cause further damage.

Through both its anti-inflammatory and antioxidant properties, Arazine reverses the effects of chronic irritation to moderate effects of skin aging.

Dr. Gregory Stock, Signum Biosciences CEO commented: "Rohto is an ideal partner to develop skincare products using our STM technology. They have a strong emphasis on quality, they excel at product development, and the Japanese consumer is very discerning. Our collaboration will produce exciting products in 2009 that open up a new category of skincare agents."

Kunio Yamada, President and CEO of Rohto stated: "Signum's STM technology is impressive, and we are happy to get the Japanese rights to it. Our broad alliance with Signum has extraordinary potential, and as a result I've agreed to serve on Signum's Board of Directors and I have invited Signum to establish a laboratory in RVK (Research Village Kyoto), our R&D facility."
