Novel Natural Compounds Derived From Tcm In The Treatment Of Food Induced Anaphylaxis, Ibrahim Musa

NYMC Student Theses and Dissertations

Food allergy is a highly prevalent disease affecting about 30 million people in the U.S. It is managed primarily by food avoidance due to lack of promising treatment options. ASHMI (anti-asthma herbal intervention) which consists of three components, Sophorae flavescentis, Ganoderma lucidum, Glycyrrhiza uralensis has been shown to inhibit allergic lung inflammation in antigen sensitized and challenged mice. In this study we isolate and identify the active compound in Sophorae flavescentis, characterized the mechanism of IgE inhibitory effect, biomarkers and potential to prevent food anaphylaxis.

To separate and identify the compounds we used column chromatography, high-performance liquid chromatography, mass …

Pharmacological Blockade Of The 20-Hete Receptor Lowers Blood Pressure And Alters Vascular Function In Mice With Vascular Smooth Muscle- Specific Overexpression Of Cyp4a12-20-Hete Synthase, Kevin Agostinucci

NYMC Student Theses and Dissertations

20-hydroxyeicosatetraenoic acid (20-HETE) is the ω-hydroxylation product of arachidonic acid catalyzed by CYP4A and 4F enzymes. 20-HETE is a vasoactive eicosanoid of the microcirculation exhibiting effects on both vascular smooth muscle cells (VSMC) and endothelial cells (EC). In VSMCs, 20-HETE’s bioactions include the stimulation of contraction, migration, and growth. In ECs, elevated 20-HETE is associated with reduced nitric oxide (NO) bioavailability, increased angiotensin converting enzyme (ACE) expression, and the promotion of inflammation. Recently in our laboratory, we identified GPR75 as a novel target of 20-HETE that promotes changes in blood pressure and vascular function. The aim of this study is …
