Study Supports Development Potential in Several Therapeutic Areas
Zengen, Inc. announced today that its researchers have discovered that activation of melanocortin receptors (MCR) subtypes MC1R and MC3R could be a novel strategy to control inflammatory disorders.
The findings, "Targeting Melanocortin Receptors as a Novel Strategy to Control Inflammation," appear in the March 2004 issue of Pharmacological Reviews, a publication of the American Society for Pharmacology and Experimental Therapeutics (ASPET).
"MCR activation causes a collective reduction of the major molecules involved in the inflammatory process," said Anna Catania, M.D., professor of endocrinology, School of Internal Medicine, University of Milan and lead author of the study. "This discovery is significant because it shows that treatment with melanocortin peptides doesnt abolish the inflammatory response but instead modulates it. An advantage of melanocortins in the treatment of inflammation is that their influences are broad and are not restricted to a specific mediator or chemical pathway."
Recognition and cloning of five melanocortin receptors has greatly improved understanding of peptide-target cell interactions. Preclinical investigations indicate that activation of certain MCR subtypes, primarily MC1R and MC3R, could be useful in treatment of localized and systemic inflammatory disorders. These include: organ transplantation, chronic inflammatory diseases, acute inflammation, inflammation within the brain and neurogenerative disorders, peripheral neuropathies, systemic host reactions, ischemia and reperfusion injury and infections.
"The study results also indicate that certain melanocortin peptides have antimicrobial effects," said James Lipton, Ph.D., chief scientific officer and director of Zengen and study author. "Unlike corticosteroids, melanocortins do not reduce microbial killing activity, but enhance it. We are encouraged by these findings and will continue our research and development efforts in peptide technology."
Zengens researchers also conducted a separate study on melanocortin receptors that was published in the February 2004 issue of the Journal of Leukocyte Biology. The study, titled, "Autocrine inhibitory influences of alpha-melanocyte-stimulating hormone in malignant pleural mesothelioma," showed that activation of express melanocortin 1 receptor (MC1R) by selective peptides or peptidomimetics might provide a novel strategy to reduce mesothelioma cell proliferation by taking advantage of an endogenous inhibitory circuit based on alpha-Melanocyte-Stimulating Hormone ((-MSH), and its receptor MC1R.

Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz (Germany) together with scientists from Dresden, Leipzig, Sofia (Bulgaria) and Madrid (Spain) have now developed and characterized a novel, metal-organic material which displays electrical properties mimicking those of highly crystalline silicon. The material which can easily be fabricated at room temperature could serve as a replacement for expensive conventional inorganic materials used in optoelectronics.
Silicon, a so called semiconductor, is currently widely employed for the development of components such as solar cells, LEDs or computer chips. High purity...

When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, one can ask how it can be influenced in a controlled way.
We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold...
