摘要:
The present invention pertains, at least in part, to novel substituted tetracycline compounds. These tetracycline compounds can be used to treat numerous tetracycline compound-responsive states, such as bacterial infections and neoplasms, as well as other known applications for tetracycline compounds such as blocking tetracycline efflux and modulation of gene expression.
摘要:
The tetracycline class of antibiotics has played a major role in the treatment of infectious diseases for the past 50 years. However, the increased use of the tetracyclines in human and veterinary medicine has led to resistance among many organisms previously susceptible to tetracycline antibiotics. The recent development of a modular synthesis of tetracycline analogs through a chiral enone intermediate has allowed for the efficient synthesis of novel tetracycline analogs never prepared before. The present invention provides more efficient routes for preparing the enone intermediate and allows for substituents at positions 4a, 5, 5a, and 12a of the tetracycline ring system.

摘要:
7-Disubstituted-phenyl tetracycline compounds are disclosed herein. Also disclosed is a method for treatment or prevention of spinal muscular atrophy using the 7-disubstituted-phenyl tetracycline compounds. This invention also relates to a method for treating or preventing a subject having spinal muscular atrophy. The method includes administering to the subject an effective amount of a tetracycline compound of formula (1), such that the spinal muscular atrophy is treated or prevented. Advantageously, the tetracycline compounds used in this method of the invention have one or more of the following characteristics: 1) potency in modulating mRNA splicing, 2) potency in modulating SMN protein levels, 3) central nervous system (CNS) and/pr brain penetration, 4) decreased phototoxic properties and 5) decreased antibacterial properties.
