In continuation of my update on Rapamycin
"Allosteric regulators are better than proteasome-affecting agents used in clinics because they do not induce classical drug resistance," Dr. Gaczynska said. "They bind to sites on the proteasome molecule used by natural regulatory proteins. They are more specific and are not restricted to proteasome inhibition but can activate the proteasome under certain conditions."
The new strategy was serendipitously found during experiments with rapamycin, a drug that in a highly publicized study by the UT Health Science Center's Barshop Institute for Longevity and Aging Studies was found to extend life span in mice.
Potential
The Molecular Pharmacology report and follow-up studies describe the unexpected and highly desired effects that rapamycin and similar compounds elicit on the proteasome. Based on these studies, it would be possible to design a new line of proteasome regulators with anti-cancer properties, Drs. Osmulski and Gaczynska said....
