摘要:
We describe a bis-benzylidine piperidone, RA190, which covalently binds to the ubiquitin receptor RPN13 (ADRM1) in the 19S regulatory particle and inhibits proteasome function, triggering rapid accumulation of polyubiquitinated proteins. Multiple myeloma lines, even those resistant to bortezomib, were sensitive to RA190 via ER stress-related apoptosis. RA190 stabilized targets of human papillomavirus (HPV) E6 oncoprotein, and preferentially killed HPV-transformed cells. After p.o. or i.p. dosing of mice, RA190 distributed to plasma and major organs excepting brain, and potently inhibited proteasome function in skin and muscle. RA190 administration i.p. profoundly reduced growth of multiple myeloma and ovarian cancer xenografts, and oral RA190 treatment retarded HPV+ syngeneic mouse tumor growth, without impacting spontaneous HPV- specific CD8+ T cell responses, suggesting its therapeutic potential. The bis-benzylidine piperidone RA190 is a new orally-available proteasome inhibitor. Multiple myeloma, cervical and ovarian cancers are particularly sensitive to RA190.
摘要:
Disclosed herein is a method for selectively modifying a substitutable carbon atom of an organic compound containing an amine, a sulfide, or an amine and a sulfide. The method makes use of the reactivity of amines and sulfides, which can be selectively oxidized to form oxides that are inert under the conditions of many modification reactions and selectively reduced, by protecting the amine, the sulfide, or the amine and the sulfide in the organic compound as an oxide; subjecting the oxide-containing organic compound to reaction conditions suitable to effect a modification reaction; and deprotecting the amine, the sulfide, or the amine and the sulfide in the modified oxide-containing organic compound using a reducing agent, thereby selectively modifiying a substitutable carbon atom of an organic compound containing an amine, a sulfide, or an amine and a sulfide.
摘要:
The present invention relates to a method for preparing t-butyl 2-((4R,6S)-6-formyl-2,2-dimethyl-1,3-dioxan-4-yl)acetate having optical activity, which is a core intermediate in the preparation of a variety of HMG-CoA reductase inhibitors. According to the preparation method of the present invention, it is possible to easily mass-produce t-butyl 2-((4R,6S)-6-formyl-2,2-dimethyl-1,3-dioxan-4-yl)acetate in the form of a solid of high and uniform purity by using a polymer-supported TEMPO.
