Description：Seladelpar (MBX-8025) is an orally active, potent and specific PPARδ agonist with an EC50 of 2 nM. Seladelpar shows more than 750-fold and 2500-fold selectivity over the PPARα and PPARγ receptors, respectively. Seladelpar can be used for the study of primary biliary cholangitis.

In Vitro：Seladelpar (MBX-8025) is an orally active, potent (2 nM), and specific (>750-fold and >2500-fold compared with PPAR-α or PPAR-γ receptors, respectively) PPAR-δ agonist being developed as a lipid-altering agent[1]. Seladelpar is a potent, and selective PPAR-δ agonist (50% effect concentration human PPAR-δ=2 nM, PPAR-α=1,600 nM) that demonstrates favorable effects on insulin resistance, diabetes, and atherogenic dyslipidemia[2].

In Vivo：From weaning, female Alms1 mutant (foz/foz) mice and wild-type littermates are fed an atherogenic diet for 16 weeks; groups (n=8-12) are then randomized to receive Seladelpar (10 mg/kg) or vehicle (1% methylcellulose) by gavage for 8 weeks. Despite minimally altering body weight, Seladelpar normalizes hyperglycemia, hyperinsulinemia, and glucose disposal in foz/foz mice. Serum alanine aminotransferase ranges 300-600 U/L in vehicle-treated foz/foz mice; Seladelpar reduces alanine aminotransferase by 50%. In addition, Seladelpar normalizes serum lipids and hepatic levels of free cholesterol and other lipotoxic lipids that are increased in vehicle-treated foz/foz versus wild-type mice. This abolished hepatocyte ballooning and apoptosis, substantially reduce steatosis and liver inflammation, and improve liver fibrosis. In vehicle-treated foz/foz mice, the mean nonalcoholic fatty liver disease activity score is 6.9, indicating nonalcoholic steatohepatitis (NASH); Seladelpar reverses NASH in all foz/foz mice (nonalcoholic fatty liver disease activity score 3.13). In atherogenic diet-fed Wt mice, administration of Seladelpar reduces body weight by ～18% (Pfoz/foz mice. These animals develope severe hyperglycemia, hyperinsulinemia, and whole-body insulin resistance after 16 weeks (Pfoz/foz mice (Pfoz/foz mice (PWt mice (P[2].

Animal Administration：Mice[2] From weaning (week 4), Alms1 mutant (foz/foz) NOD.B10 mice or Wt littermates (female mice in both groups) are fed an atherogenic diet (23% fat, 0.2% cholesterol and 45% simple carbohydrate; 4.78 kcal/g digestible energy) ad libitum for 16 weeks, after which groups are randomized (n=8-12 mice/group) to once-a-day oral administration (by gavage) for 8 weeks of Seladelpar (10 mg/kg in 1% methylcellulose) or vehicle (controls). Animals are housed under 12-hour light/dark cycle and constant temperature of 22°C and receive maximal humane care[2].
