Experiment 1 Reporting the Activity Data of This PDC [1]
Indication Type 2 diabetes
Efficacy Data Body weigth change
10%
Administration Time Every day; over 8 days
Administration Dosage 2.5 µM
Evaluation Method Body weigth change assay
MOA of PDC
In vitro studies revealed that the tesaglitazar-[F7, P34]-NPY conjugate selectively activates PPARγ in NPY7R-expressing cells and enhances adipocyte differentiation and adiponectin expression in adipocyte precursor cells.Additionally, tesa-NPY induces adipocyte differentiation in vivo.
Description
The mice treated with tesa and tesa-NPY (3) did not change significantly, whereas their littermates treated with [F7, P34]-NPY (2) or vehicle/untreated lost approximately 3% of their body weight (Figure 7A).

Experiment 2 Reporting the Activity Data of This PDC [1]
Indication Type 2 diabetes
Efficacy Data Cholesterol level
2.8
Administration Time Every day; over 8 days
Administration Dosage 2.5 µM
MOA of PDC
In vitro studies revealed that the tesaglitazar-[F7, P34]-NPY conjugate selectively activates PPARγ in NPY1R-expressing cells and enhances adipocyte differentiation and adiponectin expression in adipocyte precursor cells.Additionally, tesa-NPY induces adipocyte differentiation in vivo.
Description
The influence of tesa, tesa-NPY (3), and [F7, P34]-NPY (2) on the plasma lipids was also analyzed (Figure 9). The vehicle/untreated db/db mice showed elevated levels of triglycerides and free fatty acids (FFA) compared to the lean C57BL/6N mice. Treatment with tesa and tesa-NPY (3) led to a normalization of the triglycerides, FFA, whereas [F7, P34]-NPY (2) and vehicle/untreated had no influence on the lipid metabolism (Figure 9A/B). The cholesterol levels were unchanged by any treatment as these levels were also comparable in the untreated db/db mice compared to the lean mice (Figure 9C).

Experiment 3 Reporting the Activity Data of This PDC [1]
Indication Type 2 diabetes
Efficacy Data HbA1C change
1.05%
Administration Time Every day; over 8 days
Administration Dosage 2.5 µM
MOA of PDC
In vitro studies revealed that the tesaglitazar-[F7, P34]-NPY conjugate selectively activates PPARγ in NPY1R-expressing cells and enhances adipocyte differentiation and adiponectin expression in adipocyte precursor cells.Additionally, tesa-NPY induces adipocyte differentiation in vivo.
Description
Whereas in the vehicle/untreated mice, the HbA1C values increased by approximately 2%, a graduated reduced increase was seen for [F7, P34]-NPY (2), peptide conjugate (3), and tesa (Figure 8A). Body temperature, which decreased to 35 C in the vehicle/untreated db/db controls, was normalized to 36 C in all of the treated mice including the mice treated with [F7, P34]-NPY (2) (Figure 8B). Treatment with tesa and tesa-NPY (3) led to normalization of the plasma concentration of ketone bodies and adiponectin, whereas [F7, P34]-NPY (2) and vehicle/untreated showed no effect (Figure 8C/E). Treatment had no major influence on the insulin and Mcp-1 levels (Figure 8D/G). The serum leptin concentration was reduced in the mice treated with tesa, whereas no reduction was detectable in all of the other treated mice (Figure 8F).
