Comparative study of pheophytin a and pheophytin b monolayers

Abstract

I wish to thank my adviser, Professor Quentin Van Vifinkle, for his continued interest and support in initiating and bringing to fruit the research reported herein. It is an understatement to say that without his unusual courage of moral conviction and high standards for academic performance this work could not have come into being. I wish to acknowledge the assistance of the members of the Chemistry Department Machine and Glassblowers Shops in construc tion of various pieces of apparatus used in the research. I am indebted to H.F. Blanck Jr., P. Kullavanijaya, and J, Larry for assistance in calculations of the osciallator and dipole strengths of the visible and ultraviolet light absorption of the chlorophylls and several of their derivatives, I wish to thank H.F. Blanck Jr., and J. Larry for as sistance in performing the work on the spectroscopic and stability studies, and for many stimulating discussions. I am especially appreciative for the support my family has given me, and for the patience shown in the hardships endured to accomplish this work.

Anti-Inflammatory Activities of Euglena gracilis Extracts

“…Here we report that pheophytins also quenched reactive oxygen species (Figure 6) and increased the reducing potential in cells (Figure 5). However, pheophytin a (sFE2) only prevents LPS-induced lipid peroxidation (Figure 7), revealing a more meaningful activity for pheophytin a or different stability [45]. The pheophorbides in sFE8 reported a substantial reduction in TNF-α production, with no antioxidative potential.…”
