TAK-448 acetate is an oligopeptide analog that acts as a potent agonist of the KISS1 receptor (GPR54; IC₅₀=460pM, EC₅₀=632pM)[1-2]. TAK-448 acetate is a C‑terminal analog of endogenous kisspeptin‑54. Acute administration stimulates the release of luteinizing hormone (LH) and follicle‑stimulating hormone (FSH), while sustained exposure downregulates the pituitary‑gonadal axis, thereby rapidly reducing testosterone levels. TAK‑448 acetate is primarily utilized in research related to endocrine regulation and prostate cancer therapy [3-4].
In vivo, TAK-448 acetate (in the form of the sustained‑release formulation TAK-448‑SR(1M)) was administered as a single subcutaneous injection (0.03–3mg/kg) to male F344/N Jcl‑rnu/rnu rats bearing VCaP prostate cancer xenografts (starting from week 7 post‑implantation, repeated every 4 weeks). TAK-448 acetate significantly reduced plasma testosterone and LH levels, suppressed the growth of testes, prostate, and seminal vesicles, and rapidly lowered plasma prostate‑specific antigen levels[5]. In a mouse model of metabolic dysfunction‑associated steatotic liver disease (MASLD) using DIAMOND male mice, continuous subcutaneous infusion of TAK‑448 acetate (0.3nmol/h) via osmotic minipumps for 6 weeks, TAK‑448 acetate significantly inhibited hepatic de novo lipogenesis, reduced the synthesis of free fatty acids associated with obesity, diabetes, and hepatocellular carcinoma, ameliorated hepatic steatosis and insulin resistance, and down‑regulated the expression of key lipid‑droplet regulators such as CIDEA and the transcription factor SREBP‑1c[6].

| Animal experiment [1]: | |
Animal models | DIAMOND mice (C57BL/6J × 129S1/Svlm background) |
Preparation Method | Mice were fed a Western diet with sugar water (WDSW) for 6 weeks to induce metabolic dysfunction-associated steatotic liver disease (MASLD), then subcutaneously administered TAK-448 acetate (0.3nmol/h) via osmotic minipumps for 6 weeks while maintaining WDSW. Deuterium-labeled water (²H₂O) was provided during the final week to trace de novo lipogenesis (DNL). Mice were sacrificed for hepatic and metabolic analyses. |
Dosage form | 0.3nmol/h; subcutaneous continuous infusion; 6-week duration. |
Applications | TAK-448 acetate significantly reduced hepatic DNL, decreased intrahepatic fatty acid synthesis, and lowered liver triglyceride content, serum free fatty acids, and ALT levels. TAK-448 acetate improved insulin sensitivity and glucose tolerance, and downregulated key lipogenic regulators via AMPK activation, demonstrating therapeutic potential against MASLD. |
