Background: Blockade of the renin angiotensin<br />

aldosterone system is recommended<br />

in patients with arterial hypertension. The new<br />

direct renin inhibitor has been shown to be effective<br />

and safe in hypertensive patients in randomized<br />

clinical trials. However, there are only<br />

few prospective data on blood pressure control<br />

in patients with the direct renin inhibitor aliskiren<br />

in a daily practice setting available.<br />

Methods: In the non-interventional 3A Registry<br />

patients were eligible for inclusion in whom<br />

the physician had decided to modify the antihypertensive<br />

therapy. This included treatment<br />

with the direct renin inhibitor aliskiren or an<br />

ACE inhibitor (ACE-I)/angiotensin receptor<br />

blocker (ARB) or agents not blocking the reninangiotensin-system<br />

(RAS), alone or on top of<br />

an existing drug regimen. Patients were prospectively<br />

followed for one year. Here we report<br />

the for the first time the results of the 2-year<br />

follow-up.<br />

Results: Of the 14988 patients recruited by 923<br />

physicians in Germany in 2008 and 2009, two<br />

year follow-up has been available in 61%.<br />

Patients with aliskiren showed better blood<br />

pressure reduction after two years than patients<br />

with ACE-I/AR or without RASS-blockade both<br />

in the office blood pressure (mean reduction in<br />

BP in %: 12.9+12/10.3+14 vs. 10.9+13/8.5+13 vs<br />

10.5+12/9.0+13; p-value < 0.001/< 0.01) and in<br />

the 24-hr ambulatory blood pressure (mean reduction<br />

in % , 8.4+11/7.7+12 vs. 6.3+11/5.4+12<br />

vs. 7.2+9/6.6+10; p-value < 0.05/0.05).<br />

Conclusions: In this large real life registry in<br />

hypertensive patients an aliskiren-containing<br />

regimen showed better blood pressure reductions<br />

after 2 years than patients without RASblockade,<br />

or an ACE-I/ARB-containing regimen.<br />

These results support the findings from<br />

randomised clinical trials<br />

Activation of the peroxisome proliferator-activated<br />

receptor gamma (PPARγ) exhibits beneficial<br />

effects on the regulation of genes involved<br />

in glucose and lipid metabolism. However,<br />

the currently used synthetic PPARγ agonists,<br />

the thiazolidinediones, lead to increased body<br />

weight, fluid retention and increased risk for<br />

heart failure. These side effects reveal the need<br />

for further investigation of favorable PPARγ ligands.<br />

Besides its antihypertensive properties, the angiotensin<br />

type 1 (AT1) receptor blocker telmisartan<br />

has been shown to act as partial agonist of<br />

PPARγ. In the present study we characterized<br />

new PPARγ agonists (compounds 1-3) based<br />

on the structure of telmisartan to develop new<br />

therapeutic strategies against insulin resistance<br />

and type 2 diabetes mellitus. PPARγ is the<br />

“master regulator” of adipocyte differentiation,<br />

and its activity closely correlates with the degree<br />

of differentiation. Adipocyte differentiation<br />

assay was performed with 3T3-L1 cells and analyzed<br />

by Oil-Red O staining. Cells stimulated<br />

with compounds 2 and 3 show a stronger differentiation<br />

grade compared to telmisartan at<br />

1µM and 10µM and a similar differentiation level<br />

like the full agonist pioglitazone. Luciferase assay<br />

with COS-7 cells, transiently transfected with<br />

pGal4-hPPARγDEF, pGal5-TK-pGL3 and pRL-<br />

CMV confirmed the results of Oil-Red O staining.<br />

Compared to pioglitazone, luciferase activity<br />

increased more pronounced with compound<br />

3. For further characterization, we performed<br />

ligand-binding domain (LBD) studies using<br />

time-resolved Fluoreszenz-Resonanz-Energy-<br />

Transfer with the corepressor NCoR1 and the<br />

coactivators PGC-1α, SRC-1 and TRAP220.<br />

Binding of our compounds to the PPARγ-LBD<br />

caused a conformational change which resulted<br />

in dose-dependent release of NCoR1 similar<br />

to telmisartan and pioglitazone and selective<br />

coactivator recruitment. Microarray analysis<br />

and qRT-PCR showed a differential geneexpression<br />

under distinct agonist stimulation.<br />

Here, we reported new PPARγ ligands with partial<br />

and full agonistic receptor activation and selective<br />

cofactor recruitment/gene expression.<br />

Thus, these new PPARγ ligands act like SP-<br />

PARMs. Metabolic efficacy of these compounds<br />

needs to be elucidated in the future.<br />
