Dual inhibitors of inosine monophosphate dehydrogenase and histone deacetylase based on a cinnamic hydroxamic acid core structure
摘要:
Small molecules that act on multiple biological targets have been proposed to combat the drug resistance commonly observed for cancer chemotherapy. By combining the structural features of known inhibitors of inosine monophosphate dehydrogense (IMPDH) and histone deacetylase (HDAC), dual inhibitors of IMPDH and HDAC based on the scaffold of cinnamic hydroxamic acid (CHA) have been designed, synthesized, and evaluated in biological assays. Key features, including the linker length, linker functionality, substitution position, and interacting groups, have been explored. Their individual contribution to the inhibitory activities against human IMPDH1 and IMPDH2 as well as HDAC has been assessed. (C) 2010 Elsevier Ltd. All rights reserved.
allow release of the desired products from the solidsupport under very mild conditions is of great interest in organic synthesis and combinatorial chemistry. We describe an enzyme-labile safety-catch linker which releases alcohols and amines through i) enzymatic cleavage of an amino group and ii) subsequent lactam formation. The linker group was investigated on different polymeric supports: TentaGel

In this paper we report the scope and limitations of Pd(0)-mediated coupling reactions between aromatic iodides linked to a polystyrene resin and terminal acetylenes and olefins (Heck reactions). Optimized reaction conditions were evaluated with a number of different reagents. The optimized reaction conditions were frequently found to be superior to those previously reported in the literature and resulted in excellent yields of the products upon cleavage from the solid phase.

Straightforward syntheses of two tert-alkoxysilyl chloride functionalised resins 3 and 31 that allow facile attachment of 1 degrees, 2 degrees, 3 degrees alcohols and phenols to the solid-phase have been achieved. Resin 3 displayed useful loading levels (0.7 mmol/g), and it was stable to storage in activated form. Siloxanes from reaction of 3 with alcohols and phenols were compatible with a variety of reaction conditions commonly used in solid-phase synthesis. (c) 2006 Published by Elsevier Ltd.
