As a comparison, the ECL1 of GIPR partially unwound with the presence of three proline residues (P195 ECL1 , P197 ECL1 and P199 ECL1 ), resulting in reduced interactions between ECL1 and tirzepatide compared to that in GLP-1R (Fig

With regard to glutamine metabolism, inhibition of glutamine utilization has likewise been incorporated into the clinical development strategy of metabolic targeting plus immunotherapy. Animal studies have shown that JHU083, a prodrug of the glutamine antagonist 6-diazo-5-oxo-L-norleucine (DON), not only suppresses tumor growth, but also reshapes the transcriptional profile and antigen-presentation/inflammatory cytokine characteristics of tumor-associated macrophages, shifting them from an immunosuppressive tendency toward a functional state more favorable for antitumor immunity (118)
