Preparation and biological evaluation of 5-substituted retinoic acids
摘要:
Various 5-substituted retinoic acids were prepared by a palladium-catalyzed cross coupling reactions of vinyl nonaflates and E-or Z-3-tributylstannyl-2-beten-1-ol as a key reaction. These coupling products were then converted to the corresponding all-E-and 9Z-retinoic acid analogs via Horner -Emmons reaction and subsequent basic hydrolysis, and their biological activities were evaluated. The all-E-derivatives, 5-butyl and isobutyl analogs exhibited stronger effects for anti-proliferative and differentiation-inducing activities in HL-60 cells. In contrast, in 9Z-derivatives, none of the analogs showed any activity. (C) 2008 Elsevier Ltd. All rights reserved.

The invention features methods of treating a proliferative disorder characterized by elevated Pinl marker levels and/or reduced Pinl Ser71 phosphorylation in a subject by administering a retinoic acid compound. Additionally, the invention features methods of treating proliferative disorders (e.g., proliferative disorders characterized by elevated Pinl marker levels) by administering a retinoic acid compound in combination with another anti-proliferative compound. Finally, the invention also features methods including high-throughput screens for discovering and validating Pinl inhibitors.

The invention features all-trans retinoic acid (ATRA)-related compounds capable of associating with Pin1 and methods of identifying the same. The invention also provides methods of treating a condition selected from the group consisting of a proliferative disorder, an autoimmune disease, and an addiction condition characterized by elevated Pin1 marker levels, Pin1 degradation, and/or reduced Pin1 Ser71 phosphorylation in a subject by administering a retinoic acid compound. Additionally, the invention features methods of treating proliferative disorders, autoimmune diseases, and addiction conditions (e.g., diseases, disorders, and conditions characterized by elevated Pin1 marker levels) by administering a retinoic acid compound in combination with another therapeutic compound. The invention also features a co-crystal including Pin1 and a retinoic acid compound. Finally, the invention also provides methods of developing and identifying enhanced Pin1 -targeted ATRA-related compounds based on the newly defined unique binding pockets in the Pin1 active site revealed from the co-crystal structure, structure-activity relationship, and structural modeling.
