In this study, 4‐{2‐(2‐thienyl)ethoxy}phthalonitrile ( 3 ) and its tetra substituted peripherally metal‐free 4 ), lead (II) 5 magnesium 6 cobalt 7 phthalocyanines were synthesized. The structural characterization of the obtained compounds was performed by a combination FTIR, 1 H‐NMR, UV–vis, MALDI‐TOF techniques. inhibitory properties these determined using Ingkaninan's methods against cholinesterase enzymes. Compound had highest enzyme effect toward AChE BuChE enzymes with IC 50 values...

High-density lipoprotein cholesterol (HDL-C) levels are inversely related to the risk of coronary artery disease (CAD). Alterations in HDL-C subclass distribution and HDL-associated enzyme activities may be more important than total HDL for progression CAD. We intended investigate relationship with CAD.Our study included 101 patients stable disease, 64 healthy subjects. Serum lipoprotein-associated-phospholipase A2 (HDL-LpPLA2), paraoxonase 1 (PON1), subfraction were measured. found...
