PG-901
Based on 1 Customer Validation
PG-901 is a selective MC5R agonist and also an MC3R/MC4R antagonist. PG-901 activates the MC5R‑cAMP‑PKA signaling axis in skeletal muscle, mediating increased skeletal muscle glucose uptake and enhanced glycolysis. PG-901 downregulates genes related to pro-hypertrophy, cardiac remodeling, inflammation, and fibrosis, including αSMA, αSKA, TGF-β, IL-6, NOS2, Col3A1, Nppb, and CTGF, and reduces JNK/ERK phosphorylation and cAMP levels. PG-901 synergizes with insulin to increase glucose uptake in myotubes, improves glucose tolerance in wild-type mice, and lowers fasting plasma glucose in MC4R-deficient mice. PG-901 can be used in research related to diseases such as cardiac hypertrophy, heart failure, and diabetes.

In Vitro
PG-901 (10-100 nM) increases glucose uptake in immortalized human LHCN-M2 myotubes in a dose-dependent manner, with 10 and 100 nM producing 2-DG uptake of 344.2 and 393.8 nmol/mg, respectively; at 100 nM, it increases glucose uptake in myotubes derived from primary human vastus lateralis muscle[5].
PG-901 (0.1 nM) prevents Ang II-induced leucine incorporation and attenuates the induction of Tgfb1/Ctgf in H9c2 cells; it inhibits JNK phosphorylation in NMCMs and prevents Ang II-induced leucine incorporation[3].
PG-901 has an EC50 = 0.072 nM for hMC5R; it is also a full antagonist of hMC3R and hMC4R (Kb = 1.0 nM and 0.53 nM, respectively)[7].

In Vivo
PG-901 (1 µg/g body weight; intraperitoneal injection; single injection; 15 minutes before glucose bolus) improves glucose tolerance in healthy wild-type C57Bl6 mice and does not improve glucose tolerance in MC5R-deficient mice[5].
PG-901 (1 µg/g; intraperitoneal injection; two injections; six-hour interval) lowers fasting blood glucose in MC4R knockout mice and maintains this effect during the two injections spaced six hours apart[5].
