Electrospray-ionization mass spectrometry study of cyclodextrin complexes with A007 prodrugs
摘要:
Electrospray-ionization mass spectrometric (ESIMS) studies of several A007 prodrugs in aqueous cyclomaltohexaose (alpha-cyclodextrin, alpha-CD), cyclomaltoheptaose (beta-cyclodextrin, beta-Cl), and cyclomaltooctaose (gamma-cyclodextrin, gamma-CD) were performed. The acetic acid derivative of A007 should metabolize in vivo before becoming the A007 prodrug, while on the other hand, the glycine-modified A007 prodrug has surfactant-like physical properties and slowly hydrolyzed in the aqueous cyclodextrins by releasing free A007. ESIMS studies give insight into the process of prodrug hydrolysis in the presence of cyclodextrins and, hence, the influence of cyclodextrins on the timely release of the A007 prodrug. Formation of various molecular aggregates and cyclodextrin inclusion complexes of A007 prodrugs and their hydrolyzed products was demonstrated by ESIMS. (C) 2009 Elsevier Ltd. All rights reserved.

This invention relates to a novel class of compounds which are cysteine protease inhibitors, including but not limited to, inhibitors of cathepsins K, L, S and B. These compounds are useful for treating diseases in which inhibition of bone resorption is indicated, such as osteoporosis.
The present invention provides a compound of Formula (I) or the pharmaceutically acceptable salts, esters, and prodrugs thereof, which are ERK2 inhibitors. The invention also provides a pharmaceutical composition comprising an effective amount of at least one compound of Formula (I) and a pharmaceutically acceptable carrier. The invention also provides a pharmaceutical composition comprising an effective amount of at least one compound of Formula (I) and an effective amount of at least one other pharmaceutically active ingredient (such as, for example, a chemotherapeutic agent), and a pharmaceutically acceptable carrier.
The present invention relates to a novel class of substituted spirocyclic compounds. These compounds can inhibit histone deacetylase and are suitable for use in selectively inducing terminal differentiation, and arresting cell growth and/or apoptosis of neoplastic cells, thereby inhibiting proliferation of such cells. Thus, the compounds of the present invention are useful in treating a patient having a tumor characterized by proliferation of neoplastic cells. The compounds of the invention may also be useful in the prevention and treatment of TRX-mediated diseases, such as autoimmune, allergic and inflammatory diseases, and in the prevention and/or treatment of diseases of the central nervous system (CNS), such as neurodegenerative diseases. The present invention further provides pharmaceutical compositions comprising the compounds of the instant invention and safe dosing regimens of these pharmaceutical compositions, which are easy to follow, and which result in a therapeutically effective amount of these compounds in vivo.
