Effect of dietary patterns on the blood/urine concentration of the selected toxic metals (Cd, Hg, Pb) in Korean children.

This study was aimed to examine the association the blood/urinary concentration of toxic metal (Hg, Pb, and Cd) with children's dietary patterns. This cross-sectional study included 1026 school children aged 8-17 years. Dietary patterns were defined using factor loading scores for 108 foods from a Semi-Quantitative Food Frequency Questionnaire.

The Relationship between Occupational Status and Physical Activity in Korea.

This study examined the association between occupational status and physical activity (PA) in Korea. A total of 9,000 Koreans age 10 to 89 years participated in the Korean Survey of Citizens' Sports Participation project in 2012. However, 3,851 participants were excluded from the analysis (housewives, students, and the jobless), providing a sample size of 5,149 participants (3,165 men and 1,984 women) for this study.

Development of 3D-QSAR CoMSIA models for 5-(biphenyl-2-yl)-1H-tetrazole derivatives as angiotensin II receptor type 1 (AT1) antagonists.

As a development strategy for backups of Fimasartan (1), a comparative molecular similarity indices analysis (CoMSIA) of a set of sixty-five 5-(biphenyl-2-yl)-1H-tetrazole derivatives has been performed to find out the pharmacophore elements for angiotensin II receptor type 1 (AT1) blockade. The most potent compound containing pyrimidin-4(3H)-one ring, Fimasartan (1) was used to align the molecules. As a result, we obtained 3D-QSAR model which provided good predictivity for both the training set (q(2)=0.

Synthesis and antihypertensive activity of pyrimidin-4(3H)-one derivatives as losartan analogue for new angiotensin II receptor type 1 (AT1) antagonists.

The discovery, in vitro and in vivo studies of the highly potent AT(1) antagonist 12a (BR-A-657, Fimasartan) antagonists are presented. A series of pyrimidin-4(3H)-one derivatives as losartan analogue were synthesized and evaluated for a novel class of AT(1) receptor antagonists. Among them, 12a containing thioamido moiety displayed both high in vitro functional antagonism and binding affinity [IC(50)=0.

Safety, tolerability, pharmacokinetics, and pharmacodynamics of fimasartan following single and repeated oral administration in the fasted and fed states in healthy subjects.

Background And Objectives: Fimasartan (BR-A-657) is a novel, non-peptide angiotensin II receptor antagonist with a selective type I receptor blockade effect. Two first-in-human studies investigated the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of fimasartan.

Methods: Fasted single oral tablet doses of fimasartan 20-480 mg or placebo were administered to 40 healthy male subjects (aged 19-54 years) in a double-blind, randomized, sequential-group design.
