Problems solved by technology

[0016] However, alteration of the basic ring system or substitution of substituents at one or more positions at positions 4 and 10-12a often results in synthetic tetracyclines with significantly reduced antimicrobial activity or practically no antimicrobial activity

Embodiment

[0087] The following exemplary data are used to provide a further understanding of the present invention, but are not meant to limit the effective scope of the present invention in any way.

[0088] Several studies have been performed to examine the efficacy of doxycycline and two non-antibiotic biochemically modified tetracyclines (CMT-3 and CMT-8) on certain pathological features of aortic stenosis involving matrix metalloproteinases- 9 (MMP-9) synthesis, angiogenesis and apoptosis.

[0089] The study was performed using tissue collected from four surgically removed stenotic tricuspid valves. Valve tissue samples were incubated with different concentrations of tetracycline (TC), CMT-3, CMT-8 or solvent for 10 days.

[0090] Gelatinases (MMP-2 and MMP-9) were assayed from valve tissue samples. The analyzed bands were related to the total protein measured using the Bio-Rad DC protein assay kit (Bio-Rad, Hercules, CA).

[0091] All cultured valves expressed bands consistent ...

Abstract

The present invention is for a method for treating aortic stenosis in a mammal in need thereof. The method comprises administering an effective amount of a non-antibacterial tetracycline formulation, to the mammal.

Description

Background technique [0001] The aortic valve connects the heart's lower left chamber (ventricle) to the body's largest artery, the aorta. Aortic stenosis, also known as aortic stenosis, is a condition in which the valve of the artery becomes narrow. This narrowing prevents the aortic valve from opening fully, which prevents blood from flowing from the heart into the aorta and on to the rest of the body. As a result, the heart pumps less blood with each beat and less blood reaches all parts of the body. [0002] Aortic stenosis can be mild, moderate, or severe. Symptoms may include fatigue, dizziness, chest pain or pressure, fainting, shortness of breath, palpitations, heart murmurs, or swelling of the ankles or feet. If left untreated, aortic stenosis can lead to serious heart problems, including heart failure and sudden death. [0003] Treatment options for aortic stenosis include surgery and / or medication. Rarely, the opening of the aortic valve can be widened using a t...
